 Most ships of Garland's class had the rear torpedo tubes replaced by a 12-pounder AA gun after the evacuation of Dunkirk in 1940, but it is not known exactly when this modification was made. By 1942, the ship's short range AA armament had been augmented by two 20 mm (0.8 in) Oerlikon guns on her searchlight platform and another pair on the wings of the ship's bridge.' Y 'gun was also removed to allow her depth charge stowage to be increased. The .50-calibre machine gun mounts were replaced by a pair of Oerlikons later. The ship's director-control tower and rangefinder above the bridge were removed in exchange for a Type 271 target indication radar, after 1942, and 'B' gun was replaced by a Hedgehog anti-submarine spigot mortar. A Type 286 short-range surface search radar was probably also fitted mid-way through the war. The ship also received a HF / DF radio direction finder mounted on a pole mainmast.
