Some of the ships had an extra one or two Oerlikons fitted on top of the superstructure amidships. The Captain-Class units had additional 20 mm guns fitted in 'X' position, and on the director stand for 'X' position. Torpedo tubes: 3 21-inch (533 mm) torpedo tubes in a triple mount were mounted just aft of the stack. Hedgehog: British designed ahead throwing mortar which fired 24 bombs ahead of the ship, this was situated on the main deck just aft of A gun mount. Depth charges: Up to 200 were carried. Two sets of double rails each side of the ship at the stern, each set held 24 charges; eight (two on Captain-class units) K-gun depth charge throwers each holding 5 charges, were situated each side of the ship just forward of the stern rails. On Captain-Class ships, just forward of these double sets of ready racks were fitted along each side of the ship extending to midships, each set holding 60 depth charges (these ready rails were added after the ships first arrived in the UK)

The Buckley-class destroyer escorts were 102 destroyer escorts launched in the United States in 1943–44. They served in World War II as convoy escorts and anti-submarine warfare ships. The lead ship was USS Buckley (DE-51) which was launched on 9 January 1943. The ships had General Electric steam turbo-electric transmission. The ships were prefabricated at various factories in the United States, and the units brought together in the shipyards, where they were welded together on the slipways.

The Buckley was the second class of destroyer escort, succeeding the Evarts-class destroyer escort. One of the main design differences was that the hull was significantly lengthened on the Buckley; this long-hull design proved so successful that it was used for all further destroyer escort classes. The class was also known as the TE type, from Turbo Electric drive. The TE was replaced with a diesel-electric plant to yield the design of the successor Cannon-class destroyer escort ("DET").

A total of 154 were ordered with 6 being completed as high speed transport ("APD"). A further 37 were later converted after completion while 46 of the Buckleys were delivered to the Royal Navy under the Lend-Lease agreement. They were classed as frigates and named after captains of the Napoleonic Wars, and formed part of the Captain-class frigate along with 32 ships of the Evarts-class destroyer escort.
