The squadron was re-formed briefly in 1945 and then again in 1947 as a fleet requirements unit to evaluate naval use of helicopters.

The aircraft were equipped with floats so that they could be launched from the ships by catapult and then recovered from the water by crane.

Early in World War II the squadron saw service protecting troop convoys and hunting raiders on the North America and West Indies Station.

705 Naval Air Squadron was briefly reformed in 1945 and carried out the role of torpedo training.
