High Quality Content by WIKIPEDIA articles! The Charles F. Adams class is a ship class of 29 guided missile destroyers built between 1958 and 1967. Twenty three ships were built for the United States Navy, 3 for the Royal Australian Navy, and 3 for the West German Bundesmarine. The ships were based on the existing Forrest Sherman class, but were the first destroyers designed to serve as missile destroyers. They added 19 feet (5.8 m) of length to the center of the Forrest Sherman design to accommodate the ASROC launcher and changed the boilers from 600 psi (4,100 kPa) to 1,275 psi (8,790 kPa). Both of these changes ultimately caused significant maintenance problems for all ships in the class. The Charles F. Adams-class destroyers were the last steam-powered destroyers built for the U.S. Navy; beginning with the follow-on Spruance-class destroyers, all succeeding destroyer classes have been powered by gas turbines. The destroyers of this class served in the Cuban blockade of 1962 and the Vietnam War.
