John C. Butler-class destroyer escort

The John C. Butler class destroyer escort originated during World War II. The lead ship was USS John C. Butler (DE-339), commissioned on 31 March 1944. The class was also known as the WGT type from their Westinghouse Geared Turbine drive. Of the 293 ships originally planned, 206 were canceled in 1944 and a further four after being laid down; three were not completed until after the end of World War II.

The standard armament for the class was two 5 in dual purpose guns, four 40 mm and ten 20 mm anti-aircraft guns, and three 21 in torpedo tubes. It also carried two depth charge racks, eight depth charge projectors and one hedgehog projector as secondary weapons. The ships had a maximum speed of 24 kn.

The most notable ship of this class was USS Samuel B. Roberts (DE-413), which gained fame during the Battle of Leyte Gulf, where it, along with several other ships engaged a number of cruisers and battleships of the Imperial Japanese Navy in a torpedo attack, where it was sunk after taking several hits. During this action, Samuel B. Roberts achieved a speed of 28.7 kn for over an hour by running her engines at 660 psi.

A floating history museum of the destroyer escorts resides in Albany, NY. USS Slater (DE 766) (a related Cannon-class DE) is docked during temperate months on the Hudson River in Albany, New York. An Edsall class destroyer escort, USS Stewart, is also on display as a museum ship in Galveston, Texas.
