Ribursli/Behemoth class carrier with 340 crew. The C8V fleet carrier was the first major foray of the Imperial Klingon navy into carrier technology. Designed as the answer to the Federation Ark Royal class, the C8V was put into service in the 2280s and has been in production ever since. Usually operates in Carrier Battle Groups that can consist of a mix of assault ships and command ships. It is known a handful were lost in the kinshaya war during the initial phases of the invasion and that despite the resource shortages, Houses have done their best to keep these operational for prestige reasons.
D'aka/ Mover class assault ship with 62 crew and 800 troops. The T-3 was no longer in production by the end of the 23rd Century, with 480 vessels having been built. Since then, most have been allocated to reserve fleets, 112 destroyed, 5 scrapped and 53 sold to private interests.

older assault ship with Houses that cannot afford newer models. House Koryak has a few T-3 assault ships in varying degrees of operational condition. The House tries to keep them operational to keep face within Klingon society.

T-3K vessel IKS G’ongTHa is one such vessel. Originally commissioned in the early 2270s, the G’ongTHa has seen action in many of the assault actions of the 2270s and 2280s and is decorated accordingly with these victories. In recent years the credit has not been there to maintain the warp drive system and the ship has been restricted to being docked for training purposes. Many warriors start with the static ship before moving onwards to other, operational assault ships.

There are plans afoot to take parts from the T-3H vessel IKS H’rea to restore the G’ongTHa back to operational status.

Mas To Gal/ Throne Seeker assault ship with 76 crew and 1400 troops. The T-5B were produced, about 14 per year, at Fonawl and Mustaka. By the end of the 23rd century, the T-5 was still in production, with over 343 vessels having been built. Over the years, 4 vessels were allocated to reserve fleets, 47 destroyed, with 14 T-5As and 4 T-5Bs sold to private interests. About 120 of the T-5A models were converted to the T-5B design

This assault ship discontinued production in the early 2300s, with resources being re-distributed to newer assault ship models and smaller ship designs. The T-5 is the most numerous assault ship amongst the Houses and many are now being passed down to the smaller Houses as the Great Houses acquire the newer, larger models.

House N’reden, a minor House in the driftward region of the Empire, has recently acquired a handful of early T-5A models and a T-5B in a blood debt from House MoraKh. This minor House is now looking to upgrade the design to T-5B standard.

House MoraKh is looking to introduce a T-5C upgrade to bring the T-5 up to T-12 standard, increase automation to free up extra space for more troops.

IKS R’karia, a T-5A Mas To Gal assault ship was part of the assault teams involved in the Tabula Rasa campaign. The decorated ship, along with famed Brigadier L’tek, had been involved in the campaign from early on, securing many worlds for the Klingon Empire and assuring a supply of dilithium and other minerals were sent back to the Empire. Once the Metar were uncovered, the R’karia was assigned to try and stem the Metar advance. When this proved impossible, the ship was assigned a rearguard action whilst the main body of the fleet withdrew, pending the detonation of the second Shiva device to seal the systems into their subspace prison.

The R’karia was last seen trying to get to a safe distance, her propulsion systems had been badly mauled by the Metar and her escorting D-10 and D-7 had suffered equally as bad. None of the ships escaped the blast and were pulled back into the Tabula Rasa systems, along with the Metar. The ships are considered lost honourably in battle.
Carrier of Doom/Na Ra'den assault ship with 82 crew, 2,400 troops. The T12 Carrier of Doom class was introduced in the late 2270s. These vessels were produced at Fonawl, Iosia and Mustaka, at a rate of about 14 per year. They were the biggest assault ships in the Imperial Klingon navy at the time of their commission. They were used in the assault on Mrzicann where the 800 000 defenders were forced to surrender within 12 hours.

Starfleet Intelligence nicknamed them the 'Mantis' class due to their shape. Over 102 vessels have been built. Over the years, 2 vessels were allocated to Klingon Imperial Marine Training Command, and 12 destroyed - mostly in the ISC Pacification War. The war highlighted a flaw in the design: the short range of its disruptor fire. These weapons were designed only for close in fire support, making these ships require escorts in space-based battles.

Largest assault ships in service. Devised in the late 2260s by House MoraKh, as a larger assault ship in their House tradition of planetary assaults. These soon became the assault ship of choice for the Great Houses. In the reign of Chancellor Azetbur, with a reduced demand for invasion forces to keep the Federation aid on-side, the T-12 ships were mothballed in numbers to free up resources for the rebuilding of Kronos.

With the growing discontent from the outer colonies of the Empire in the latter years of Azetbur, the T-12 forces were re-activated by order of General Gorak to send troops to quell the growing unrest. In concert with T-15 assault ships the T-12 were able to deploy troops quickly to bring the insurrection to heel. Following the assassination of Azetbur by Gorak, and the subsequent dishonouring of his House, the T-12 force of House Gorak is awaiting re-allocation to those Houses loyal to new Chancellor Kaarg.

IKS Bo’thada is the former flagship of General Gorak. The General rejected calls to serve aboard a D-9, D-7 or D-9 cruiser, preferring the company of the warriors under his command. Gorak led by example and his choice of flagship matched this. This T-12 vessel had a custom upgrade of the command and control facilities, allowing the General to control his planetary actions from this ship. This earned the warship the designation as T-12D due to the significant differences to previous vessels of the class. The Bo’thada was involved in Gorak’s campaigns to bring the colonial unrest to a halt, the General unleashing the full might of the 2400 troops on his ship to full effect. With the completion of the campaign, the Bo’thada was ordered back to the House dockyard to undergo a deep refit. Midway through this refit the General assassinated Chancellor Azetbur and work on this ship ceased. The ship now awaits its new owner as Chancellor Kaarg disbands the dishonoured House belongings.

IKS R’shar is the sole warship belonging to House R’shar. This House has their entire belongings and family members all aboard this assault ship. The House specialises in assault operations and has successfully fought alongside several Chancellors. With all of the House based aboard the ship, all of the victories and wealth are turned over back into the ship, constantly improving the systems and weapons. This T-12 is considered to be amongst the most advanced in service and has been given the designation T-12G.

The T15 Beachhead class assault carrier with 90 crew and 5000 troops was quickly put into service in the mid-2280s as an assault ship version of the existing carrier design recently introduced. The vast hanger bays made for assault shuttles as well as 5000 troops. The successful blitzkrieg assalt on Ch'ramak was an early indication of the wisdom of this decision. This design is still in production as a replacement for the earlier assault ships. To-date there are over 20 in service with production continuing pace with the carrier variant as resources allow.

This assault carrier refit of Ribursli was designed by House MoraKh as a successor design to the T-12. In the event, the current sparse numbers of T-15 mean that they are used in concert with the T-12 for blitzkrieg assaults on planets. With a short design-to-production rate due to being based on the successful Ribursli carrier, the T-15 was seen in service from the mid-2280s. The T-15 proved to be essential for the Kinshaya War in both deploying troops to defend worlds of the Klingon Empire but also in the later stages of the war to counterattack and secure territory.

WoQ' a'/Ultimate Power B-14. This was first proposed in the High Council and green-lit in 2288 as a successor to the B-12. A lack of resources and willingness has kept this ship on the construction slip ever since. The WoQ’ a’ was proposed as a follow-on to the B-12 Sword of Kahless battleship. Chancellor Kesh proposed the design in 2288 to secure his position as leader of the most powerful House in the Empire. As construction of the second and third B-12 battleships was then underway, the WoQ’ a’ remained in ‘development Hell’.

Shortly after the launch of the second B-12, the Tabula Rasa event created a potential new source of minerals to complete warships faster. The B-14 programme was working off the back of the B-12 design and a realistic date of 2293 was set for initiating construction of the hull. As the third B-12 was nearing completion, Chancellor Kesh was killed in a challenge for leadership by General Gorkon. With Kesh now dead, the B-14 programme was immediately frozen. The civil war that consequently erupted saw House g’Iogh making sure that House Kesh would not cut short their new-found position as Emperor. The prototype B-12 was laid down some point in the mid-2290s and progressed little from being a modified B-12 hull number 5. An intelligence analysis from the turn of the century determined that at current progress the prototype would be finished by the mid 2320s.

With the return of the now-House of Kaarg to power, the B-14 WoQ’ a’ programme is set to restart and the prototype could be ready for trials in under 4 years.

B-13 Ber'taa. Cancelled project from the 2280s which was seen as the new terror by 2288. A wrecked hull from this design floats over Hydrax as a symbol of their liberation, a visible sign of the abject failure of this design in actual combat. The prototype and early pre-production model was sent to the kinshaya front to test the design in combat. The warship showed a number of design flaws resulting in the execution of several engineering officers and this still did not save the ship from eventual destruction.












qeyleS bat'leH/Sword of Kahless battleship. Three built with at least another in a partial state of construction. Upgrade of this B-12 design with a view to production was postponed to prioritise smaller ships. Crew 770. Vessels include: B12-001 IKS qeyleS bat'leH, B12-002 IKS yejquv ghop and B12-003 IKS wo'HubwI', flagship of the House G'Iogh, which was destroyed in 2291. After this point the B-12 was mothballed, only seeing service to protect Kronos against the kinshaya and featured in Operation Hammerblow. The Sword of Kahless was mothballed again after the war and has been seen seldom since.

3 built, 1 left, 1 under construction but unfinished. The second vessel of the class, yejquv ghop, was acquired by Brigadier Kerla from the discommended House of General Grokh, for his treason on Chang’s ship, Dakronh. General Kerla worked as the right hand man of Chancellor Azetbur, acting as her enforcer. This second battleship was unmatched except by the prototype. The second B-12 yejquv ghop was lost in the final moments of Operation Hammerblow when General Kerla turned the potential failure of the mission into victory by assaulting the flagship and escorts of the kinshaya forces. The yejquv ghop was destroyed, taking the kinshaya flagships with her. The action secured the name of Kerla in the Hall of Heroes as well as reaffirming the B-12 as a Goliath of a warship. Rumour has it the son of Kerla was promised a B-12 of his own by Azetbur once he had achieved the appropriate rank.

Intelligence does suggest the House of g’Iogh is building a fourth B-12 but that this will not be in service for at least four years. The construction was halted early on and the battleship has been overlooked in favour of restoring a large number of smaller vessels.









Emperor Melkor's early Accuser class flagship mupwI'

pumwI'/Accuser class dreadnought with crew of 660. 38 built to-date. This is the B-11, the latest incarnation of the legendary B10 battleship. It takes twice as long as Emperor class to build these ships. Used as battlegroup leader, a refit is due once prioritised smaller ship refits/new builds completed. The lead ship was brought back online in 2294.

This vessel fought in the Tabula Rasa and Klingon civil war. The kinshaya Pacification War exposed the sluggish nature of the Accuser class and many were lost as a result. The cloaking devices were found to be less effective for these larger vessels, allowing the kinshaya a chance to detect the dreadnought. Post-Praxis there was a lack of resources and the D-10 Riskadh class had the flexibility for troop transportation whereas the Accuser class was a pure old school battlewagon.

Surviving vessels are:

  • B11-013 pumwI'/Accuser (replacement for lost prototype).
  • B11-103 mupwI'
  • B11-104 Kesh (named by the House of Kesh for their Chancellor and Head of House).
  • B11-107 ????
  • B11-108 ????
  • B11-109 ????
  • B11-110 ????
  • B11-111 ????
  • B11-112 ????
  • B11-113 ????
  • B11-114 ????


  • Kaarg's vessel is B11-104 Kesh, named for his late father and Chancellor. The kinshaya war saw the ship pushed into service before being mothballed. With Kaarg now Chancellor, his connections with the other Great Houses means his battleship has been prioritised for re-activation. The old 'Kronos One' moniker attached to D-7 K'T'inga class battlecruisers seems irrelevant to the new Chancellor as he will make his mark with a new flagship that will be untouchable to any Constitution class treachery as per 2293.

    The Accuser class was retained for the fleet flagship role only. The dreadnought is not a diplomatic emissary like the D-7 K'T'inga class, this is a battlewagon built in low numbers to take out primary capital ships and facilities of the enemy. After the Klingon Civil War in the early 2290s and the kinshaya War of Pacification, only 14 B-11 Accuser class remain in service. Under the later years of the Azetbur Era, these battleships were mothballed in favour of resurrecting and building a larger number of the smaller warship types. With the coming to power of Chancellor Kaarg, he has made a request to resurrect the B-11 warship belonging to his House to stand as a symbol or the rebuilding of the Empire. The Kesh is due to re-enter service in 2313.

    In 2292, Melkor, so-called 'Emperor' in 2292, used the Accuser class mupwI' as his early flagship. Captain Torlek got an Accuser class dreadnought, IKS mIl’oD, later on in the campaign; it was commanded by one of Melkor’s top officers. The crew, realising his treachery, killed him and swore allegiance to Chang.

    At least 14 left in various states. Command ships for multiple fleet size actions. Houses MoraKh, Kaarg and Stex each have a B11. (Leaves room for others later.) These warships are decorated with the victories that each House has amassed with these flagships. The five warp nacelles are necessary to allow a smooth transition to warp with the inferior Klingon warp technology. This is the largest class of Klingon ship fitted with a cloaking device to-date.

    It is believed one of the other B-11 warships has been allocated to House g’Iogh as a gesture of alliance between J’bok of the House g’Iogh and the House of Kaarg. This is now the largest vessel the formerly disgraced House possesses, although Intelligence suggests they are also in possession of assault ships. Rumours still abound that they are aspiring to build the fourth Sword of Kahless B-12 class vessel.

    Author's notes: these are the equivalent of the real-life Russian Kirov class Heavy Missile Crusers. These Goliaths were created by the Soviet Navy and forced the USN to resurrect their Iowa class battleships as a response. After the fall of the Soviet Union these Kirov class warships became too expensive to upkeep and by 1999 all but the last member, Petr Velikiy, were laid up awaiting repairs or scrapping. In recent years, Vladimir Putin has announced the resurrection of all four Kirov class vessels, although the former-Frunze looks like it may never happen and the first for revival, Admiral Lazerev (former Kalinin) has been put back from 2012 to 2018 just this month (June 2013).



  • pumwI'/Accuser class dreadnought with crew of 660. This earlier version of the legendary B-11 had only 2 Graf unit warp nacelles and additional heavy weapons, giving the battleship status, lesser manoevreability and heavier armament. This variant has been phased out with the later Accuser class design.

    pumwI'/Accuser class carrier with crew of 660. This was an experiment by the Klingons in the 2280s to quickly get their numbers of carriers raised. The classic B-11 design was stripped and redesigned for fighter groups. A dozen or so entered service although it is unknown how many are operational as the C8V has been prioritised over this C-11V variant. The additional carriers became useful during the kinshaya War of Pacification and it is possible that Chancellor Kaarg may yet use this design to project power with a revitalised Imperial Klingon navy.

    This carrier variant of the B-11 was converted from 4 incomplete Accuser class hulls during the kinshaya invasion. This was used as a quick-fix measure to get large carriers up and running to stop the kinshaya armada pushing deeper into Klingon space. Shown to be an effective fleet carrier, at least two C-11V were retained as carriers after the war but it is thought the others are lined up by their Houses to have their original construction completed as B-11 variant.

    Komo Val/ Ever Victorious class pocket battleship with 1070 crew 480 troops. First appearing just before the launch of Excelsior, the Komo Val was the most sophisticated ship the Klingons had ever designed. It was a game-changer. As with Excelsior, there were construction difficulties (transwarp for the NX 2000) due to the shortage of rare minerals. After the crude L-13 Fat Man, this is a technical ship. The prototype had shakedown issues from all of the technology. After Praxis the L-24 program slowed to a crawl. Despite the Federation fearing the Klingons had an advantage with the delays of NX 2000, only 1 was operational in the 2290s with the others awaiting components. After the destruction of Kronos One over Ch'ramak, Chancellor Azetbur took on the Komo Val as her new flagship. Chancellor Kaarg inherited six and prioritised completing them and production of others.

    The L-24 program was kick-started by Chancellor Azetbur when Kronos was in danger of being overrun by the kinshaya. The battleship could resist the effect of the PPD. These ships soon were out of service after the war due to shortage of parts.



    L-24 class, most advanced warship the Klingons have built. Requires rare minerals and high tech, slowing production. The troops can be beamed down within 7 minutes. The Tabula Rasa campaign, and later the kinshaya war, sped up the construction through necessity. The prototype and pre-production vessels were built at the Taamar shipyard, production expanding to a second facility at Gnuu Re' by the mid-2290s.

    With the rise to power of Chancellor Kaarg, the mineral reparations from the Interstellar Concordium and the supplies gained from mining in the Far Stars duchy in Lyran space have been used to build more L-24 warships. Houses that ordered these pocket battleships are now able to bring them online. In 2313 it is discovered there are far more operational than was first thought.
    Keth Ke Se/ Fang Filled Maw class pocket battleship with 487 crew 200 troops. The L-20 Keth Ke Se was the most expensive ship ever constructed at he time the prototype was built. Built for House Kinzan, this was the direct ancestor of the Komoval design. Keth Ke Se and Virkon remain the only two in service, with a possible third incomplete hull. Still 2 in service. Designed by Captain Kanger and built at the Thoras shipyards. This ship has an assault shuttle bay fitted on the lower hull. The prototype destroyed three Romulan ships in the Triangle region.

    With the success of Keth Ke Se and Virkon, serious thought has now been given for the completion of the unfinished third hull and potential orders for more. The two existing ships have been updated with new command and control systems and classified as L-20B.



    The L-13 Kel'rianda/Fat Man - with 1062 crew and 420 troops - was the first attempt by the Empire to build a battleship to match Starfleet's Federation class dreadnought. The design was of limited success with a final L-13D variant coming out in the 2280s before being superceded by the prototype L-24 class. The L-13B design was scrapped at initial prototype stage, the L-13C appeared in the early 2270s as an upgrade. All surviving members are of the D-variant, although these are being run down (similar to the Russian Typhoon class SSBNs in the early 2010s). Twenty-one were eventually produced at Taamar

    The final nail in the coffin for the Fat Man design was the kinshaya war, which highlighted the shortcomings of this now-obsolete design. The Fat Man was used as a monitor design, protecting vital colonies and worlds against kinshaya attacks.






















    VoDIeh/ Emperor class battlecruiser with 505 crew. C-10 an upgrade from -A and -B versions with new systems. This was developed from the D-7 K'T'inga class as the D-7XDN project to upscale the already successful K'T'inga into a light dreadnought to either supplement or replace the bulkier B-11 class Accuser dreadnought.

    The additional warp nacelles gave the VoDIeh class more range in a manner similar to the Federation Constellation class deep range cruiser. The result is a deep range strike cruiser that was designed to penetrate deep into Federation space and take out strategic targets. These ships were planned to divide and disable Starfleet responding to a Klingon offensive in the inevitable war.

    General Chang was behind the project, taking the prototype as his flagship during the civil war of 2292. General Kalnor also possessed another of the earlier pre-production VoDIeh class ship. Chang crippled the ship before killing Kalnor in the rite of Blood Peace. Captain Torlek got an Emperor class cruiser, IKS may van Bom, and Chang noted it belonged to Colonel Drakkor, a close personal friend of his, who saved hundreds helping in the evacuation of qvaQ starbase. Chang could not alter his death but could find a worthy successor.

    The VoDIeh was next used in the kinshaya War of Pacification in deep strike missions deep behind enemy lines - performing the very rle for which it was designed. Some of the most successful missions of the war against kinshaya supply lines and support bases.

    Recent intelligence reports that VoDIeh class vessels from various Houses are being refit ready for deployment. The list of potential destinations for these ships is currently too long to identify the target.

    The VoDieH proved useful in the kinshaya and kinshaya wars with their deep range ability. Currently these vessels are used as flagships in the region need Vudar and kinshaya space, as well as command ships for operating in the remote Far Stars duchy region of Lyran space. IKS VentaH is one such VoDieH class operating in the Far Stars duchy. She is operated by House P’tookH as their flagship, whilst sending out B’rel class scouts and PIh class science vessels to locate minerals and resources for the House.

    Vessels include: IKS voyge, IKS v I'nIchu.
    The D-24 tel'Iw/Bloodwing battlecruiser with 430 crew is the first Klingon design to enter service after the Praxis Event. This is from a Klingon designer known as Kleev.
    Death Boot by KoraH.

    Hegh daS Death Boot by KoraH.

    The D-13 Hegh daS/Death Boot battlecruiser with 85 - 420 crew was the last battlecruiser design prior to the Praxis Event of 2293. The prototype was undergoing testing at the time of the explosion, whilst the second was dashed to pieces along with the yard. Production was re-started from Z'hai yards a decade after the Praxis explosion. After a decade testing the sole member of the heavy destroyer class, production is now underway and is looking to be the lean-manned reploacement for the K'teremny class.














    The D-9 Warrior's Anger was created by Doj'kan of House Gorthas as an evolution of his D8-134 SuvwI' QeH in 2270. Based upon an enlarged version of the D8 hull, the D-9 suvwI' Qeh/Warriors Anger class is a command cruiser variant, used to lead squadron and task group sized elements of the Imperial Klingon fleet. She has 395 crew. The length is 336 metres, beam 156 metres and height 78 metres. This is a design with more power, yet less agility; the Klingons ensure these ships are guarded by smaller picket ships.

    The D-9 Warrior's Anger class was designed in the Dek'Go'Kor Military Academy yards. The D-9 was designed to be a command ship that would take over the role from the D-10 Riskadh. The prototypes were rebuilt from older series D-7G K'T'inga warships from the 2270s. The extensive rebuild included an additional warp nacelle and extensive command and control systems. These prototypes - Starfleet designation D-7CNC/XD-9A - were tested extensively along the Federation border in preparation for General Chang's perceived imminent war with Starfleet. The first D-9As appeared around 2287 and were seen during the Tabula Rasa campaign and later civil war quite extensively.

    After Praxis the D-9 Warrior's Anger is the largest class of vessel still in production besides the L-24 Komo Val. Armed with 2 forward and rear disruptors with 2 forward photon torpedo bays and GHRC. Upgrade with new command & control systems due. During the Interstellar Concordium Pacification War the Warrior's Anger class command cruisers were used along with D-7 K'T'inga class cruisers to form squadrons that were both fast and could hit hard.

    With the resources for building and restoring warships being drained from the Klingon Defence Force, the Warrior's Anger command cruiser has become the capital ship of choice for Houses, requiring less to maintain than the B-11 Accuser or C-10 Emperor classes. Many of the Warrior's Anger class are named for Generals and famous leaders of Great Houses. There were an estimated 30 in service by the 2290s and over 70 in service today.

    Vessels include: IKS tlh'lwnuy, IKS poQuyno, IKS jaDu, IKS Hengen, IKS Qinguq.


    The D-10 Riskadh battlecruiser was introduced on 9th June 2269. This ship was designed for superiority and to carry three companies of marines for boardings and ground assault. Each of the massive cargo bays contains ground vehicles, 150 troops in cryo-stasis and ample transporters. Houses have converted them into carriers (D-10C), an ELINT/scout version (D-10E) and also transports (D-10T). In 2275 one D-10 was converted into the D-10R IKS Molkatha, a research ship for new weapons systems. She was refitted in 2277 and a prototype assault disruptor refit in 2290. Only 3 were sold to outside nations, mostly the Lyrans. Two main variants in service: D-10F is 2300s stopgap refit of the D variant and the D-10G a deep refit of the Riskadh.

    During the Tabula Rasa campaign, D-10s were present in numbers, leading the assaults on the virgin planets and their minerals. One, along with a K'T'inga and B'rel, was involved in the attack on U.S.S. Potemkin, Cochise, Kerch and Hirayama. When the Metar were awakened, those same D-10s were used as command and control assets until they were overrun by the advanced ancients. When Kesh died and the battle for success started, D-10s were involved in the civil war that followed, aiding in the rival Houses fighting for leadership. The D-10s were fond to be a good compromise for power and armour over the larger, sluggish Sword of Kahless battleships.

    The next major observed use of D-10 Riskadh was during the kinshaya War of Pacification. As the kinshaya crossed into Klingon space, so D-10s were used to land troops, co-ordinate resistance and fight the kinshaya warships head on. The great battle of Operation Hammerblow had some 35 D-10s involved. The big capital ships were able to soak up lots of damage from the kinshaya battlecruisers before they were destroyed. It was from some of the glorious battles of this war that many Houses have gained respect for the D-10. For all the lack of agility, the Riskadh has the weapons, the armour and the she power to assault worlds and space stations that appeals to the martial nature of Klingon culture.

    The D-10 Riskadh has found a role as flagship and assault ship, examples being seen in numbers in kinshaya space and assaulting Ch'ramak. Their poor agility means that they rely on either picket ships dfending them, or sheer armoured plating to survive attacks. As the D-7 K'T'inga is modernised and the L-24 Komo Val come on line, so a question remains over the need for the Riskadh. Ultimately the combination of assault ship and command ship makes the D-10 a design that will continue to be needed.

    Most numerous capital ships, used as flagship by medium and smaller Houses that cannot afford D-9 or B-11. These minor flagships are decorated with the emblems of past victories and are treated as symbols of the prestige of that House. The additional assault ship aspects of the design mean that this has been used in the kinshaya campaigns, many of them bearing the markings of previous battles in that region.

    The IKS B’wos is one such D-10, involved in battles including at Hydrax. This veteran battlecruiser is now a far cry of its former self, being the flagship of House B’oeke that opposed the decision by Chancellor Azetbur to withdraw from kinshaya space. The B’wos stayed behind as long as was strategically possible, only withdrawing when it was in danger of losing their ability to warp out under cloak with the sole remaining D-7 K’Tinga class escort.

    The D-10 was repaired with copious hull plating patches stuck over the holes that the kinshayas had put in the side of this valiant warship. Recently this flagship has started a refit to D-10F standards, with a future view to performing a deep refit to –G standards once a suitable substitute flagship is located.

    Since 2305, Azetbur began to marshal resources to the KDF to renovate House fleets in exchange for retained or renewed loyalty. Part of this was to work on flagships to lead from the top and D-10 Riskadh, D-9 Warrior’s Anger and B-11 Accuser class warships were identified for this refitting. In addition to this, new B-11 and L-24 Komoval class were to be constructed at newly rebuilt or constructed shipyards. The Federation was kept in the dark to this refurbishment of the KDF to keep relations sweet until the new ships were online. For six years, Azetbur was able to play down the growing rumours of the renewed strength of the KDF. Part of the longevity of Azetbur’s reign can be put down to the careful retention of loyalty in the right Houses to keep her position as chancellor. Azetbur wanted the Empire to realise it was self-sufficient and not dependent on aid anymore. Upgrading her flagship from the battered Kronos One to the new Komoval was part of this deliberate move.

    The D-10G Riskadh class upgrade was designed by House B’oeke for their flagship B’wos. The deep refit would renew the warship with state of the art sensors and propulsion systems, upgrading ablative armour and cloaking technology and providing the ship with the best weapon systems the House could obtain. The assault phaser mount design tested on Molkatha would be fitted on the B’wos to give her an element of the weaponry enjoyed by the Accuser and Sword of Kahless battleships. The refit D-10G design was also taken up by Torlek and his House in the Far Stars duchy region of the Lyran Star Empire. Torlek had been sent out here in 2292 by General Chang, to find his destiny and forge stronger links with their Lyran coalition partners. Torlek had been instrumental in aiding Chang in defeating the renegade ‘Emperor’ Melkor and his forces. Torlek had taken his Accuser class battleship, D-10 and a handful of cruisers into Far Stars territory to forge the links Chang spoke of. Torlek went so far as to paint some of his warships in Lyran colours to demonstrate the strong brotherhood between the warrior nations. The attempt to market Klingon designs to the Lyrans proved futile, but the markings made Torlek’s D-10s stand out. The upgrades proposed by House B’oeke appealed to Torlek, who was ever-aware that he was pioneering into the unknown as he had to be ready for whatever enemy forces he might stumble across. It also would give him the power to conquer worlds in the name of the coalition. By 2313, Torlek had refurbished the first of his ships to D-10G standards, with a second docked mid-refit.

    The House of Duras was one of the next Houses to apply the D-10G standard to their Riskadh class vessels. Their proximity to the Romulan Star Empire was cited as their reasoning. The assault phaser fitment was also a statement of power and prestige for the House and secured their status as one of the Great Houses of the High Council. The Starfleet intelligence report on the KDF in 2300 under-estimated the fleet size and capability of the ships. Yards were declared as destroyed or inoperable when this simply was not the case. The original entries stating only 1 Accuser class was operational with seven under construction fell far short of the mark when nearly half a dozen had been named in the recent Klingon Civil War of 2292. Equally the numbers of major warships had been under-estimated in the face of a 14000-ship fleet. L-24 and B-11 numbers had been under-estimated, as had D-10 and D-9 class.

    Author notes: basically saying the Klingons have about 14 capital ships for a fleet that is built up House fleet by House fleet, for a race of warriors too. It is simply too few. If I were a Klingon, I would want more than one Accuser class just for my fleet to crush my enemies, drive them before me and hear the lamentation of their women LOL. Azetbur the cunning, professional politician comes from speaking to you and the best way she can stay in power for 18 years is to give gifts of warships to loyal Houses. I also reiterate the clever, strategic, warrior Klingons will spread their shipyards around the Empire for both proximity to their Houses and for flexibility in time of war. Praxis may have wrecked the Qo’noS system but not the military-industrial complex. The picture of a battered, make-do fleet is more for Azetbur’s era, especially around the period from 2298 – 2304. A fleet build-up (like the Russians from 2007) is highly likely given the martial nature of the Klingons.

    Members of the class include: Glorious, Mind Burner, Riskadh and Varg'cel. Later variant vessels include: Claw of the Riyity, Glory, Gloryseeker and Wargiver.






















































































































    The D-7 Koro class battlecruiser came as an evolution of the D-6. These were introduced in the mid-2240s as the technological and military answer to the Federation Constitution class heavy cruiser. The previous D-6 class were matched by the Federation Ares class and the Klingons wanted to re-assert their military dominance. The Koro class was raced into service in 2245; later intelligence showed that this was at the cost of inferior construction standards and a lack of shielding on their reactors. In the event, the Constitution class was shown to be a match for the D-7.

    Between 2245 and 2265 the Koro class was built in numbers and became the standard frontline battlecruisers of the Empire; the status of any House was measured by how many D-7 Koro battlecruisers they possessed. These became the principal warship class of the Imperial Klingon Defence Force Order of Battle. During the Great Expansion of the Empire the D-7 was at the forefront, both in terms of battles, propaganda and exports. The D-7 offered for export were the 'monkey model' variants minus the ablative armour and better weapons systems. Intelligence showed that the numbers of D-7 bought by the Romulans and Lyrans were minimal and they never taken up by those nations.

    As the capabilities of the Constitution and Federation classes became known, the Dek'Go'Kor Naval Academy worked ceaselessly to further develop the D-7 design. Almost every House that ordered the Koro design had innovations to improve the combat abilities of this warship. The IKS Gr'oth was an example of the further ablative armour and upgraded weapons systems that the D-7 had over its predecessors. With these new developments the D-7 was quickly evolving into a new variant: the D-7L K'T'inga.

    The original design of the D-7A was a rush job with the aforementioned reactor and construction issues. The B model allowed these rushed factors to be ironed out and the later C, D and E models brought further improvements to the design. Cloaking technology was introduced in the later models after the short-lived alliance with the Romulans. Construction was wound down to a minimum after the introduction of the new D-7G K'T'inga class battlecruiser design.

    A programme was launched to upgrade Koro class to the new K'T'inga versions but for lesser Houses this was not possible. Hybrid D-7H Koro class appeared as Houses strived to have the best warships but lacked the resources for a full D-7 upgrade. Of the hundreds of D-7 Koro class built, most are still in service. The Houses continue to upgrade their Koro class warships with some enhanced to a degree that they are all but indistinguishable from the new K'T'inga class design.

    Author notes: The D-7 was the battlecruiser seen in the Original Series. Always referred to as D-7, this received a fan designation of Klolode class. The original script for In Thy Image, the pilot episode of Star Trek: Phase Two - which became Star Trek: The Motion Picture - named the D-7 models that were used as Koro class. These were discarded when the change was made from TV to movie standard and a new design called K'T'inga class by Gene Roddenberry was used. I use this as justification to call D-7 Koro and D-7G K'T'inga.

    My use of the Koro and K'T'inga class as being variants of the D-7 class battlecruiser is due to the appearance of the K'T'inga class CGI model being described as a 'D-7' in ST: Voyager episode "Prophecy". The D-7 has been said to be Klolode class in fandom with a later model with detailing being the Koro class. The appearance of the D-7 with the ablative armour and detailing in Star Trek: Axanar set in 2245 contradicts this with armoured plating and similar details to the later K'T'inga class. Tom Paris said the D-7 was out of service 'decades ago' and this will be true as the 2240s vintage ship will be superceded by improved D-7 K'T'inga class over the decades.

    The original D-7 model did not have the detailing that the Koro class and Gr'oth had. This was, of course, down to the 1960s production budget and needs. A detailed ship was not necessary as it was only watched on an NTSC-grade television. With HD TV and movies, more detailing was needed and I would argue this is why the new Gr'oth-style Koro class is what they 'really' look like. Besides, in the series the D-7 seen most were the Romulan ones, so the smooth look could be put down to removing the ablative armour as the cloaking device makes up for this. Perhaps these light-weight D-7 had a better speed performance in exchange for less armour?


    D-7 versions include: Atropos (Invincible) KL 10097, Flethish (Prominence) ChR 222 (In Romulan Service), Gortuk (Furious) KL 08422, Hakask (Horrendous) KL 99019, Jurakte (Assassin) KL 32533, Kahless (The Merciless One) KL 08405, Klathas (Pestilence) KL 68953, Klolode (Destruction) KL 02529, Klothos (Carnage) KL 99970, Lachesis (Havoc) KL 66065, Luctas (Starfire)ChR 316 (In Romulan Service), Makita (Executioner) KL 31060, Marta (Corona) ChR 333 (In Romulan Service), Meninarca (Gauntlet) ChR 400 (In Romulan Service), N'lanaes (Predator) ChR 385 (In Romulan Service), Parno (Broadsword) ChR 381 (In Romulan Service), Tabor (Powerful) KL 85269, Thanatos (Vengeance) KL 63573, Tor'stog (Deviser) KL 73796, Trelinitu (Starlight) ChR 566 (In Romulan Service), Tuer (Murderous One) KL 74717.

    The D-7L Q't'inga/K'T'inga class battlecruiser has 340 crew. Their are multiple variants in operation: D-7M is a 2290s refit of the L variant. D-7N is a stop-gap refit of the M variant; involves a quick refresh of all systems. D-7R is a reconnaissance/picket ship variant. D-7S is a deep refit of the M version taking 18 - 36 months. Involves new technology and strip-to-the-frames rebuild. All M refits advertised as S variant - strike version - but in truth most are the N variant due to time and lack of new technology supplies from factories. D-7T is the tanker variant constructed from M variants robbed to do N upgrades.

    The K'T'inga is the latest incarnation of the designs dating back to the D-6 of the early 23rd Century. The D-7 Koro class was the standard design encountered in the 2260s. This was upgraded with extra ablative armour-plating such as as seen with Koloth's ship IKS Gr'oth. This was designated the D-7F by Starfleet. Later during the V'ger Crisis of 2273, the K'T'inga class was first seen by long-distance probe. This was a re-working of the technology and armour seen on ships like Gr'oth, shared amongst the rest of the Klingon Houses to better the Klingon warship design. This was designated D-7G by Starfleet to reflect both the lineage of the design and also named K'Tinga to show the extent of the design re-working.

    Klingon Houses took quickly to the new design, personalising the internal fitments to match with the personal philosophies of each House. This brought about a rapid appearance of the K'T'inga class from 2270 through 2280. Ship yards were quick to re-tool themselves from building the D-7 Koro class to the newer design. This brought about Starfleet designations D-7H, D-7J and later D-7L. A later, larger version was seen in the late 2280s designated the D-9A/D-8E. This was the Warrior's Anger class command cruiser. Earlier D-7 models had their major systems upgrading to the D-7L/D-8D specifications, enhancing the warp, impulse and computer systems.

    Many D-7 K'T'inga class have had their aft torpedo launchers removing and an array adding. This was observed on Captain Kang's D-7M/D-8E warship K'Tanco when it encountered the Excelsior in the Azure Nebula in 2293. Ths modification is thought to be for two reasons: the Amar was destroyed by V'ger when retreating. The shame brought upon the crew and the Empire when Starfleet observed this act of 'cowardice' prompted the removal of the aft launcher by many so retreat was not an option. Other intelligence reports suggest the array was either an extra sensor, a communications array or possibly a concussive charge weapon or drone of sorts.

    Some K'T'inga class vessels were fitted for long-range missions during the latter years of the Kesh administration. Some vessels, such as IKS T'ong in 2290, missed their intended targets and would return later (Author's note: TNG The Emissary). Deep range Federation facilities were on the hit list, as were options for striking the Alpha Quadrant portion of the Federation. ome of the deeper space regions such as Far Stars Duchy in Lyran space was exploited and protected by long-range specialist Houses and their D-8 K'T'ingas. The IKS Voq'leng - one of the first proto-K'T'inga D-7 class set sail to find the kuvah'magh - the chosen one that will bring about a Second Empire.

    The D-7N upgrade came out of the Pacification War with the kinshaya. Several of the Houses had come up with innovations to fight off the superior kinshaya warships, as had the Dek'Go'Kor Naval Academy. The result was superior shielding and enhanced ablative armour qualities, along with more powerful disruptors and torpedoes. A strike version, the D-7S was devised for hit and run missions, being of lighter alloys and specialised weapons combinations to quickly overwhelm threats. These variants allow Houses to cherry-pick the qualities they espouse in their warships. Some go for performance, others for armoured qualities and heavy weapons. The D-8 has show it has come of age and has plenty of space to evolve ready for the threats of the future. Despite the Praxis explosion, D-8 construction still continues, with Chancellor Kaarg encouraging Houses to order more.

    K'T'inga's are the primary capital ships of the Klingon Empire and as they gain victories and famous accolades, so they are embellished with markings and extra badges to illustrate this. Just as a Klingon is loud and proud about their achievements, so their ships reflect this. Earlier model D-8s can have many of these markings, especially I.K.S. ghyywlnga (Federation callsign KRONOS ONE), which was marked up with many victories. Additional markings have been seen by Starfleet Intelligence for ships loaned to the Lyran Star Empire, especially in the Far Stars Duchy.

    The advent of the D-7S as a strike version of the K'T'inga class has created a design that rivals the L-24 Komo Val. The design shares many of the systems of the L-24 and requires less of the rare minerals that have stalled the L-24 programme for the last 20 years. Whilst barely half a dozen L-24 Komo Val are in serviceable condition, the D-8 K'T'inga upgrade is based upon available technology and parts. The proposed D-7X builds upon the incorporation of the L-24 technology and has been posited as a new battlecruiser design that will replace the L-24 Komo Val as the next generation of Klingon frontline battlecruiser. Ironic given that the L-24 was introduced in 2287 as the successor to the D-8 K'T'inga class.

    The continued delay with initial production of the L-24B Komo Val and the stalled Hegh daS/Death Boot programme has provided a window for the D-8H K'T'inga family to be upgraded for the 24th Century. The naval architects at Dek'Go'Kor are at full tilt working on the D-7X/D-8J programme, utilising the mineral supplies coming from the Far Stars Duchy region of Lyran space to work towards building up the Klingon Order of Battle once more. The ready supplies of hulls and parts is seen by Starfleet Intelligence as the most likely means by whih new Chancellor Kaarg will achieve his keynote speech declaration that he will build the fleet up to 18000 ships. It is a development that is to be scrutinised and followed with due concern.

    Star Trek: Voyager 'Prophecy' had the K'T'inga class CGI model used and identified by Tom Paris as a D-7 class battlecruiser. This makes the K'T'inga officially a direct refurbishment of the D-7 design from the Original Series, just like the Enterprise changed from the Original Series to The Motion Picture. The Klingons in Prophecy had set off in one of the intermediary designs from the Gr'oth to Amar evolution of the D-7 series.

    On a different note, the low res K'T'inga CGI model was used in the first season Enterprise episode 1x05 'Unexpected' as a Klingon battlecruiser. Obviously the design 'should' have been the D-5 or John Eaves' early D-6 model (then labelled D-4). The screencaps used here help to detail that CGI model.

    Author's notes: the K'T'inga class has been noted in various canon publications (including the excellent Haynes Bird of Prey Rotarran manual) to be a follow-up to the D-7 design from the Original Series. The designations used reflect an excellent real-world comparison to the K'T'inga: the Sukhoi Su-27 Flanker fighter. The Su-27 began life in the Soviet Union in the Late 70s as the prototype single-seater fighter designated the T-10/ RAM-K. This became a production model from the late-80s called the Su-27. Later designations came as the original single-seat Su-27 gained a second seat and other modifications. These were all Su-27 derivatives but given ther designations. Examples are: Su-30 twin seat fighter verion of the Su-27, Su-33 Flanker-D navalised version, Su-34 Fullback bomber version, Su-35(Su-27M Flanker-E modernised version) and Su-37 Flanker-F Thrust-vectoring improved two-seat fighter with multi-role.

    Just as with the new Sukhoi PAK FA T-50 being an upgrade of the Su-27, so the D-8 K'T'inga is likely to be upgraded and reclassified in the future as, for instance, the D-11, D-13 or D-15. As new major systems are created, so the D-8 design will evolve. The Dek'Go'Kor Naval Academy yards will create the new designs and the Houses will continue to personalise them to their own requirements.

    The Haynes Bird-of-Prey Rotarran manual makes it plain that each Klingon House that orders a ship personalises the weapons and general specifications of the ship to suit their own combat philosophy. This would explain Kang's ship IKS K'Tanko which was encountered in 2293 minus aft torpedo launcher. Major system upgrades would warant a new designation. The design changes from the TV show to the Motion Picture creates the D-8 designation to reflect this major change; the D-9 Warrior's Anger is another reflection of this major change. The D-7 designation is retained to reflect the lineage. This then brings up the issue of why the D-6 designation wasn't carried on. The simple reason is that Star Trek: Axanar's excellent D-6 design is a recent addition.

    On the 9th February 2013 I asked Rick Sternbach questions about the K'T'inga in relation to the Vor'cha:

    When asked about a design between K'T'inga and Vor'cha he replied:

    "Adrian - Not sure if there would be an intermediate step, but I suppose anything's possible. My sense of it is that the Vor'cha came about as an attempt by the Klingons to take in any technology that Starfleet had to offer (in the interests of friendship, uh huh) and quickly incorporate it into a new package. One could write entire techno-thriller novels over stuff like that."

    When asked about resource-heavy construction of Negh'var:

    "But knowing the Klingons, would they not put the effort into building the ships if they thought it necessary, even if it meant neglecting some parts of their civilization? Happens today in some places. This is what makes for cool stories."

    This makes the K'T'inga a long-lasting cruiser with plenty of room for upgrades. It also makes interesting comparisons to India (for example) of a country that put a lot of their GDP into military, above social needs.

    The D-7S/D-8H strike version as a rival to the L-24A Komo Val is based upon plenty of contemporary examples. The Su-35S as a stopgap for the PAK FA and the F/A-18 Super Hornet offered as a cheaper and available alternative to the expensive and delayed F-35 Lightning II. The YAH Commanche helicopter, a technical stealth marvel from the end of the Cold War, was cancelled in place of the AH-64D Longbow Apache due to the latter having active defence systems that the Commanche lacked.

    The D-7F Koro class variant was a command cruiser design that was the fore-runner of both the K'T'inga class and the Warrior's Anger class command cruiser. The Enterprise under Captain Kirk encountered the design at Kronos when they were on their classified mission regarding the Kitumba. This D-7F had enhanced weaponry and capabilty which made it a flagship design. Further examples of this class have been seen as flagships for the fleets of other Great Houses. Where Houses could not afford to build of able to obtain a Warrior's Anger class, this D7F variant has been used successfully as a substitute.

    Starfleet Intelligence reported the use of this design in the prolonged kinshaya campaign and examples appeared in the Interstellar Concordium's War of Pacification. Examples have been shown around the Mirak and Lyran border region, along with some on the Romulan border.

    Author's Note: This D-7 derivative design is by Tobias Richter and was used in Star Trek: Phase 2 episode 'Kitumba' as the command cruiser over Kronos.







    Direct forebear to the D-7 design. This mid-22nd Century battlecruiser replaced the venerable D-5 design. Introduced in the 2150s, the design could outrun the fastest Starfleet vessels then in service. In its so-called supercruise mode, the D6 was able to sustain a speed of warp 6.5. Crew of 250. The design evolved through the 23rd Century, losing the extraneous support struts and gaining extra structure around the command pod. The D-6 remains the principal warship of the Imperial Klingon Defence Force from the 2150s to the introduction of the D-7 in 2245.

    Used early on in May 2242 to take the Romulan colony world of T'lach Kor. Motak Fal'tir and several other Romulan colonies were captured before operations were suspended. The Battle of Donatu V against Federation forces was the culmination of the experience from this campaign. D6 also played a heavy part in the Axanar campaign (see Star Trek Axanar).

    D6 was refurbished in both the 2270s and 2290s, with a further series of upgrades now underway. Service Life Extension Programme (SLEP) is underway to ensure they can remain at the forefront of the Klingon Order of Battle (ORBAT) for the next twenty years and beyond.

    It is a common misconception that the IKDF uses only the latest warships. Even in 2312 there are D-5, D-6 and early series D-7 warships still in service. With the Klingon culture favouring constant combat, the Klingons have evolved to use whatever weaponry they can get. Every design improves and evolves and the D-5, D-6 and D-7 have all changed over time; cloaking technology, ablative armour and new warp, impulse and sensor systems all work to improve the design, even changing the shape and size of the design.

    Vessels include: IKS Begh'poQ, IKV Blue Fire, IKS Chong'pogh, IKV Death Hand, IKS Deb'choS, IKS Duy'Hub, IKV Fencer, IKV Fury, IKS Gho'be', IKS GhoH'Sot, IKS Hob'DIS, IKS Hurgh'ragh, IKS Luq'argh, IKS MajQa'be', IKS NaS'puchpa', IKS Nay'par, IKS PiqaD'nem, IKS Qugh'tung, IKS Qup'SoH, IKS Qut'Such, IKS TaD'moH, IKS TajHu, IKS Tar'be, IKV Two Fingers and IKS Wuv'a'tem.

    The design of the 23rd Century evolution of the D-6 was done for Star Trek Axanar. Original version of the D-6 was designed by John Eaves as the D-4, later used as a designation for a patrol vessel in Star Trek Into Darkness, hence the change from D-4 to D-6.

    The Q-9B K'teremny - crew 340 - current version, quick to build to use on the kinshaya campaign. The design programme was started at Dek’Go’Kor military academy in the 2260s. As the new design was perceived by some High Council members to threten the D-7 Klolode design, the K'teremny was politically delayed for a decade. In 2279 the Prototype was launched and had total power failure. The crew had the misfortune for the whole affair to be observed by USS Knox, but the intelligence picture gained from the drone was not complete. A year later in 2280 the USS Bradley encountered IKS Raga in sector 24187. The ensuing battle resulted in the crippled Raga self-destructing after mauling the Bradley. The next famous encounter entered the dark annuls of Starfleet history when in 2286 the USS Hood was wrecked, USS Ajax crippled and USS Achilles damaged by Qrish, using its superior manoeuvring and weapons coverage. Later in 2288 the Romulan heavy cruiser Gallant Hand, executing a retaliatory strike into Klingon space, destroyed a flotilla of K’teremny. This as a blow to the Klingon Defence Force after so many had been commissioned. A thorough investigation by Imperial Intelligence put the losses on the overconfidence of the Klingon commanders. In 2291, defector Admiral Komax in an L-24 Komo Val class Komo Hesta was defeated by his pupil, Captain Klevalt, and his K’teremny squadron. Confidence in design was restored. A Q-9C is upcoming upgrade.

  • qa'HoS/ Relentless Light Cruiser with 280 crew. This light cruiser is based on the old D-6 design. This is the Klingon equivalent to Miranda class and can be an early command for a Klingon officer. With over 50 torpedoes onboard, this ship is the typical border patrol ship, ready to defend the Empire from invaders and stop escapees. Unlike the Miranda class, this vessel is still a combat-specialist with little scope for scientific study. The Suspicious class science vessel is reserved for this function. D-17E and -F variants are latest in service with -G version coming online.

    The PIh/ Suspicious class battle frigate has a crew of 45. This is most often the first command for a Klingon officer once they graduate from military academy. The Suspicious class comes in three versions. The battle frigate has a torpedo rollbar and marines for dealing with border patrols. These small ships offer a good potential for personal glory and have a closer-knit crew than perhaps a larger cruiser-sized vessel does.

    When comparing combat capabilities, the Suspicious class has the edge over the Federation Okinawa class. This is an acceptable compromise to Starfleet as the Okinawa class has a scientific cability the battle frigate Suspicious lacks. A lieutenant on the rise may be assigned to command a Suspicious class, patrolling the border regions or perhaps a sensitive region of facility.

    The PIh/ Suspicious class science vessel has a crew of 35. The vessel bristles with sensors and is the one true Klingon scientific ship. Any Klingon specialising in science and research would prefer to be assigned to one of these vessels. Some of these vessels have been modified for a specific Suppression of Enemy Astro Defences (SEAD) role. These would jam Federation border sensors during any attack over the border.

    The Suspicious class science or cargo versions do not have any marines onboard. These rely on the fighting skills of the crew themselves. As a result, these are not intended to put themselves into harms way. These vesssels have been employed from the start to locate minerals and useful chemicals for the Klingon Empire. The Hur'Q left the region around Qo'noS a 'mineralogical desert', as extensive studies by the U.S.S. Montrose and others have confirmed. The Empire, as a result, have always had scout vessels in abunance to scan for prospective new resources; the Suspicious class is the latest and best vessel for this role.

    The Suspicious class science vessel must use its cloaking device and cunning to evade threats, until reinforcements can arrive; failing this, the ship can use its sensors to blind and confuse the enemy. These vessels are also used for Electronic Intelligence (ELINT) and Signals Intelligence (SigINT) missions, monitoring Starfleet sensor ranges and communications signals. Often these ships can have crytographic specialists on board, breaking Starfleet and Federation codes and intepreting the messages hidden within. Intelligence reports also suggest these ships are better able to detect other cloaked vessels, for example Romulan ships. In any conflict, these ships would be the scouts sent ahead of the battlefleet to evaluate the enemy and suppress any threat sensors.

    Like the Bird of Prey, the Suspicious class can land on a planet surface. These ships can operate away for up to two years, studying a planet or phenomenon. Production and maintainance of these vessels have been a priority since Praxis, searching for a replacement source of energy. Some have studied the Tal'lhnor Nebula to seek a way of restarting the singularity that used to act as a power source.

    The cargo version is used as a covert means of supply, to get men and materials behind enemy lines or past threat sensors undetected. Intelligence reports suggest the Klingons used Suspicious class cargo vessels to ship ambassadors and manufactured goods to the Feresans. The effectivenes of the cloaking technology can be testified by the lack of detection of these multiple missions. Equally, covert trade and freight missions as well as previously in the Tabula Rasa and captured Kinshaya space. These ships have been shown they can sneak past Federation ships, with perhaps only the Phantom class super scout able to detect them.
