715 Naval Air Squadron (715 NAS) was a Naval air squadron of the Royal Navy Fleet Air Arm created in July 1936 to serve as a catapult flight of the Fleet Air Arm of the Royal Air Force. It was elevated to squadron status at the end of 1937, before being disbanded in January 1940. It was re-formed in August 1944 to operate as the Fighter Wing of the School of Air Combat, before being disbanded in March 1946, and absorbed into 736 Naval Air Squadron.^[3]

The flight originally came into being following a renumbering of the No. 403 (Catapult) Flight and operated in the 5th Cruiser Squadron in the China Station under the command of Lieutenant Commander E.O.F. Price, RN. Its shore-based headquarters was at Kai Tak Airport, Hong Kong, but it also had a satellite at Wei-Hai-Wei, China. The flight was initially equipped with Hawker Osprey III seaplanes, the navalised carrier-borne version of the Hawker Hart, and was stationed aboard the County-class cruisers: HMS Berwick, HMS Dorsetshire, and HMS Kent. It was re-equipped with Supermarine Walrus amphibious biplane in September 1936, and the last Hawker Osprey III left the flight in July 1937.

In 1937, HMS Berwick and HMS Kent left the 5th Cruiser Squadron for major refits, and the flight was rebased onto HMS Birmingham, HMS Cornwall, HMS Cumberland, and HMS Suffolk. At the end of this year, it was elevated from flight to squadron status.

On 24 May 1939 the squadron was transferred to Admiralty control, and operated from shore bases at Kai Tak and Seletar with seven Supermarine Walrus aircraft, on five RN cruisers. The squadron was disbanded at RAF Kai Tak on 21 January 1940 when all catapult squadrons were merged into 700 Naval Air Squadron.^[3]

On 17 August 1944 the squadron was re-formed at RNAS St. Merryn (HMS Vulture) to operate Fighter Air Combat Instructor and Fighter Leaders Courses, under the command of Lieutenant Commander (A) R.E. Gardner DSC, RNVR.

They used a collection of planes including the Supermarine Spitfire, a British single-seat fighter aircraft, Supermarine Seafire, a navalised version of the Supermarine Spitfire, and Vought F4U Corsair, an American carrier-based fighter-bomber, but also had access to a few Miles Master, a British two-seat monoplane advanced trainer, and North American Harvard IIB, an American single-engine advanced trainer aircraft.

On 12 December 1944 the command was passed on to Lieutenant Commander D.G. Carlisle DSC, SANF(V), and then to Lieutenant Commander F.R.A. Turnbull DSC & Bar, RN on 28 June 1945. Following the end of the Second World War, training continued for several months, but on 31 March 1946 the squadron was disbanded for the final time and reabsorbed into 736 Naval Air Squadron.^[3]
