The Hawker Hart is a British two-seater biplane light bomber aircraft that saw service with the Royal Air Force (RAF). It was designed during the 1920s by Sydney Camm and manufactured by Hawker Aircraft. The Hart was a prominent British aircraft in the inter-war period, but was obsolete and already side-lined for newer monoplane aircraft designs by the start of the Second World War, playing only minor roles in the conflict before being retired.
The Boulton Paul P.29 Sidestrand was a twin-engine biplane medium bomber of the Royal Air Force. Designed for daylight operations, it was manoeuvrable and provided with three defensive gun positions. Named after a village on the Norfolk coast near Boulton & Paul's factory in Norwich, the Sidestrand first flew in 1926 and entered service in 1928. It remained in service until 1936, equipping No. 101 Squadron RAF. It was an agile and relatively fast aircraft that was capable of aerobatic manoeuvres such as loops, rolls and spins.
The Fairey Aviation Company Fairey III was a family of British reconnaissance biplanes that enjoyed a very long production and service history in both landplane and seaplane variants. First flying on 14 September 1917, examples were still in use during the Second World War.
The Vickers Type 131 Valiant was a British general-purpose biplane produced by Vickers in 1927, with the intention of replacing the Royal Air Force's Airco DH.9As, but was unsuccessful, with only a single example built, which was sold to Chile.
The Vickers Vildebeest and the similar Vickers Vincent were two very large two- to three-seat single-engined British biplanes designed and built by Vickers and used as light bombers, torpedo bombers and in army cooperation roles. First flown in 1928, it remained in service at the start of the Second World War, with the last Vildebeests flying against Japanese forces over Singapore and Java in 1942.
Pobjoy Airmotors and Aircraft was a British manufacturer of small aircraft engines. The company was purchased by Short Brothers shortly before the start of World War II, production continuing until the end of the war.
The Miles M.20 was a Second World War British fighter developed by Miles Aircraft in 1940. It was designed as a simple and quick-to-build "emergency fighter" alternative to the Royal Air Force's Spitfires and Hurricanes should their production become disrupted by bombing expected in the anticipated German invasion of the United Kingdom. Due to the subsequent shifting of the German bombing effort after the Battle of Britain towards British cities in what became known as The Blitz, together with the dispersal of British fighter manufacturing, the Luftwaffe's bombing of the original Spitfire and Hurricane factories did not seriously affect production, and so the M.20 proved unnecessary and the design was not pursued.
The Handley Page Hinaidi was one of two twin-engine bombers built by Handley Page that served with the Royal Air Force between 1925 and 1935. The aircraft was developed from the Handley Page Hyderabad and named after Hinaidi, an RAF station in Iraq.
The Westland Wapiti was a British two-seat general-purpose military single-engined biplane of the 1920s. It was designed and built by Westland Aircraft Works to replace the Airco DH.9A in Royal Air Force service.
The Avro 549 Aldershot was a British single-engined heavy bomber aircraft built by Avro.
The Airspeed AS.45 Cambridge was a British advanced trainer of the Second World War built by Airspeed Limited. It did not reach the production stage.
The General Aircraft G.A.L.38 Fleet Shadower was a British long-range patrol aircraft design of the immediate pre-Second World War period. The Fleet Shadower was a highly specialized aircraft intended to follow enemy naval task forces over long times and radio back position information. However, the concept produced an ungainly and ultimately unsuccessful type. The Airspeed Fleet Shadower, built to the same requirement and of broadly similar appearance, also did not progress past the prototype stage.
The de Havilland DH.50 was a 1920s British large single-engined biplane transport built by de Havilland at Stag Lane Aerodrome, Edgware, and licence-built in Australia, Belgium, and Czechoslovakia.
The Saunders Roe A.37 Shrimp was a 1930s British two-seat four-engined experimental flying boat built by Saunders-Roe Limited ("Saro") at Cowes.
