USS Bainbridge (CGN-25) was a U.S. Navy nuclear-powered development of the Leahy-class cruiser. Originally a guided missile destroyer leader, the class was re-designated guided missile cruiser in 1975. As with USS Long Beach (CGN-9) and USS Enterprise (CVN-65), Bainbridge was the only member of its single-ship class.
Bainbridge (DLGN-25) was largely identical to the Leahy-class except for the replacement of her four 1200 lb/in2 steam boilers with two D2G reactors, and related increases in displacement, length and beam. Bainbridge's engineering department carried 7 officers and 156 enlisted men respectively 3 and 42 more than a contemporary steam-powered vessel.
The lessons learned on Bainbridge were later adapted to the next nuclear-powered ship, USS Truxtun (CGN-35) and the California and Virginia classes of nuclear-powered cruiser.
