    By the mid-2290s, more Constitution class had entered service in the latest configuration pioneered by the U.S.S. Levant, NCC 1843. With the Constellation, Excelsior, Oberth and Miranda classes delivered in larger and larger numbers, older classes such as Constitution class could now have an amended role to explore as a secondary ship, the Constellation and Shangri-La classes replacing it on longer range missions and Excelsior class now the number one explorer and first contact ship.

    The Constitution class still has a role within Starfleet. This famous design has been found to be very flexible and readily re-configured with the latest technology. Whilst Constellation class has the range to go further, Excelsior class has more facilities and prestige, yet the Constitution class is still a good all-round cruiser. And the design is battle-proven through some of the worst encounters Starfleet has ever had to face. Constitution II class is now being replaced by the Shangi-La and Excelsior class starships, now under construction. The design still is anticipated to be in service for another decade.

    Author's Notes:

    The registry numbers of the Constitution class are taken from Greg Jein's list from T-Negative magazine in 1975. In the starships from La Fayette to Krieger where registries are unknown, where possible Franz Joseph's registries have been used. Greg matched the registries to the list in Commodore Stone's office in Starbase 11, seen in TOS episode 'Court Martial'. Eagle, seen in an Okudagram in Star Trek VI, was given the registry by Mike Okuda of NCC 956. This is outwith the normal range of registries for the Constitution class and counter to registry established for it by Greg Jein in 1975. Therefore the Author has chosen to go with Greg Jein's list, which ironically was written the same year as Franz Joseph's 'Starfleet Technical Manual'.

    The Trek Place website is the source for these names and Greg Jein's registries. The additional Constitution class are from D.C. Fontana and Bob Justman's memos of August 8th and 9th 1967, featured in Stephen Whitfield and Gene Roddenberry's book 'The Making of Star Trek'. The 11 names selected by Bob Justman were: Enterprise, Essex, Excalibur, Lexington, Yorktown, Endeavour, Eagle, Constellation, Hornet, Wasp and La Fayette. [Obviously Constitution must have been the twelfth]. Greg Jein selected the following names for the twelve (as per Tomorrow is Yesterday): Constitution, Eagle, Endeavour, Enterprise, Essex, Excalibur, Exeter, Hood, Intrepid, Lexington, Potemkin and Yorktown.

    With the appearance of the Bozeman in TNG with the 1986 Okudagram displays on the Bridge, I have set the facts to match continuity. The 2270s refit bridge for me is the briefly-seen Star Trek IV bridge - as I have used on the Potemkin. This is the look for the Constitution class refits from the 2240s original production run. For the new-build 2280s Enterprise variant (yes, it's Enterprise variant as Enterprise was the first vessel so refit, as per 1980s fan technical manuals) I imagine a hybrid Star Trek V/VI bridge with the sleek controls of the Star Trek V bridge but with the colour displays from Undiscovered Country. Finally the newest variants have the bridge like the Sheffield, with the Enterprise B helm and Navigator stations and Tactical station at the back like on the Enterprise B.
