Project history: These four ships, laid down as DD927-930, were originally designated as destroyers, then frigates, in a new category which persisted until 1975. They owed their large size to the requirement for high speed, deeply loaded, in a seaway, and were originally designed in 1944-46 with conventional destroyer batteries, the only major innovation being the 127mm/54 guns in a twin semi-automatic version. However, as the design developed it became clear that fast carrier escorts would require maximum anti-aircraft capability, including not only guns but also fighter-direction equipment (symbolized visually by the heavy stabilized SPS-8 height-finder). For a time, it appeared that the gun battery would consist entirely of the new 76mm/70 twin automatic anti-aircraft guns, which was considered more effective than the new rapid-fire 127mm/54 (itself firing faster than the earlier twin type), but the latter was retained at the personal insistence of Admiral Nimitz, at least partly in view of the inability of the lighter weapon to deal with submarines forced to the surface. In fact the large CIC and the heavy radar were even more important; as early as 1945 it was clear that carrier fighters, controlled by the carrier and by radar-pickets such as Mitschers, would be the primary air defence of the fast carrier task force. Anti-submarine capability was secondary, as the high speed of the task force would in itself guarantee almost complete immunity. For example, in the design of the propellers and of the hull itself, high speed (to keep up with the task force) took priority over silencing. The primary ASW weapon was to be a guided torpedo, fired from a fixed tubes, with a pair of rocket launchers (Weapon Alfa) as back-up.
    High speed in a small ship meant a very compact machinery installation. All four were considered experimental, and gave considerable trouble in service, so that Mitscher and John S. McCain had to be reboilered. Indeed, engine trouble was sometimes given as the reason for the early retirement of the class. On trials, Mitscher made 34.84kts on 75,862shp at 4550t.
