Having re-equipped with Whirlwind HAS.7's, the squadron joined for a commission in the Middle and Far East in late 1957. During this time, the squadron was involved in various exercises and troop moves as a result of the deteriorating situation in Aden. Shortly after this, the squadron was heavily involved in a salvage operation when two ships collided and caught fire in the Persian Gulf. A fire party was boarded and the wounded evacuated in 845 NAS helicopters. For its part in this long and difficult operation, the squadron was awarded the Boyd Trophy for the Navy's most outstanding piece of aviation in the year. During the 1950s, 845 NAS was the only squadron to operate as a front line ASW unit and was responsible for developing most of the doctrine used by today's ASW squadrons.
