Sorley was instrumental in the specification of the armament of both the Supermarine Spitfire and the Hawker Hurricane, he founded the Empire Test Pilots' School, foresaw the need for air-to-air missiles in the post-Second World War world and, having left the RAF to join De Havilland, provided the RAF with such a weapon system.[2]
Sorley was appointed Officer Commanding No. 8 Squadron in 1931 and squadron leader at the Operational Requirements section at the Air Ministry in 1933.[2] It was during his time as squadron leader in charge at the Operational Requirements section that the Operational Requirement F.36/34, which governed the procurement of both the Supermarine Spitfire and the Hawker Hurricane, was amended on his recommendation[5] to change the armament from two .303in (7.7mm) Vickers machine guns in each wing to four .303in (7.7mm) Brownings.[6] This recommendation was based on extensive work carried out by Air Ministry staff, the mathematical calculations showing the need for eight machine guns being carried out by Captain F. W. "Gunner" Hill.[7] Sorley went on to be Officer Commanding, No. 4 Armament Training Station at RAF West Freugh in 1937.[2]
Upon his retirement from the RAF in 1948, Sorley joined the Board of De Havilland Propellers Ltd as its Managing Director, a post he held for twelve years. He recognised the need to diversify from manufacturing propellers due to the advent of the jet engine and was instrumental in the development of the de Havilland Firestreak airborne infrared missile, which became the RAF's main air defence weapon at the time.[2]

↑The attack on the Breslau became the subject of the first claim by the recently-formed RAF in the Prize Court, in which a share in the bounty for the destruction of the Breslau was claimed under the Naval Prize Act, 1918. An affidavit was presented to the court which included the following: "In addition to His Majesty's ships there took part in and were present at the destruction of the Breslau certain aircraft, a part of the Air Force, embarked in H.M.S.
