U.S.S. Lexington

Constitution class

Constitution class refit

The Constitution class Starship Lexington, commissioned in December 2247, was refit to Mark III specifications in April 2261. In 2268, the Lexington, commanded by Commodore Robert Wesley, participated in the disastrous tests of the M-5 multitronic computer. During those tests, the multitronic unit malfunctioned and fired full phasers on the Lexington, killing 53 people on that ship, as well as the entire crew of the U.S.S. Excalibur NCC-1664.

Lieutenant Watley, presumably an ancestor of Deep Space 9 chief medical officer Julian Bashir, transferred from the Lexington to the U.S.S. Enterprise NCC-1701 a few months before the M-5 tests, and unknowingly met her descendant while the Enterprise was at Deep Space K-7 in 2268.

The Lexington was upgraded to the refit Mark I specifications in February 2276. In January 2284, the Lexington was refit to Mark III specifications, then to Mark IV in September 2291. The Lexington was scrapped in December 2296.

Note

The registry listed for the Lexington in the "Star Fleet Technical Manual," NCC-1703, conflicts with the registry given in The Star Trek Encyclopedia, which was also used on screen in the remastered version of The Ultimate Computer, as well as with the registry of the U.S.S. Hood NCC-1703, and must be disregarded. Additionally, although the "Federation Ship Recognition Manual" establishes that the Lexington was lost in February 2265, and a new ship with the same name and registry constructed to refit specifications in February 2276, this conflicts with on-screen evidence and must also be disregarded.
