"Halford" was one of the three "Fletcher"-class destroyers to be completed (out of six planned) with a catapult for a float plane, the others being and . The catapult and an aircraft crane were located just aft of the number 2 smokestack, in place of the after torpedo tube mount, 5 inch mount number 3, and the 2nd deck of the after deck house which normally carried a twin 40 mm anti-aircraft gun on most ships of the class. (The twin 40 mm mount was moved to the fantail, just forward of the depth charge racks, where most ships of the class carried 20 mm mounts.) It was intended that the float plane be used for scouting for the destroyer flotilla which the ship was attached to. It would be launched by the catapult, land on the water next to the ship, and be recovered by the aircraft crane. It turned out to be not operationally suitable for the intended purpose, and the three ships were ultimately converted to the standard "Fletcher"-class configuration.
