While not adopted by Britain's Royal Air Force, small numbers were bought by the Irish Free State and Bolivia, the latter of which used the type during the Chaco War. One modified Vespa was used to set a world altitude record of 43,976 ft (13,407 m) in September 1932.
The Vickers Vanox was a British biplane bomber design intended as a successor to the Virginia for the Royal Air Force. Although it underwent extensive development, it was not successful, only a single aircraft being built.
The Westland Interceptor was a fighter developed by the British company Westland Aircraft to Air Ministry Specification F.20/27. When tested in 1929 and 1930, it showed unsatisfactory handling characteristics and was rejected by the RAF in favour of the Hawker Fury biplane fighter.
The Gloster Goldfinch was a single-engined single-seat high-altitude biplane fighter of all-metal construction from the later 1920s. It did not reach production and only one was built.
The Bristol Type 118 was a general-purpose military aircraft, a two-seat biplane built by the Bristol Aeroplane Company in the early 1930s, powered by a Bristol Mercury radial engine and aimed at overseas markets. The Type 120 was a Bristol Pegasus-engined variant entered into an Air Ministry competition and later used for armament tests. Two aircraft were built.
The Bristol Type 146 was a British single-seat, eight-gun fighter monoplane prototype built to a mid-1930s Air Ministry contract. Powered by a radial engine, it was outclassed by Merlin-engined fighters and only one was built.
The Vickers Type 279 Venom was a British low-wing monoplane single-seat, single-engined, eight-gun fighter aircraft. It was fast and manoeuvrable but its Bristol Aquila radial engine was underpowered. Together with other designs built to the same specification, which included the Bristol Type 146, Gloster F.5/34, and Martin-Baker MB 2, it was rejected by the Air Ministry and only one Venom was built.
The Vickers Vireo was an experimental low wing all-metal monoplane built to explore both all-metal service aircraft and the use of catapult launched ship board fighters. Only one was built.
The Vickers Viastra was an all-metal 12-seat passenger high-wing monoplane, with variants powered by one, two and three engines. Two twin-engined Viastras operated commercially in Australia from 1931-6; another served as a Royal transport.
The Vickers Vellore was a large biplane designed as a freight and mail carrier, in single-engined and twin-engined versions, which saw limited use as freighters and long-range experimental aircraft. A final variant with a broader fuselage, the Vellox, was completed as an airliner.
The Vickers Type 161 was an unusual 1930s pusher biplane interceptor, designed to attack aircraft from below with a single upward-angle large calibre gun. The aircraft flew well but the concept was abandoned and only one was built.
The Vickers Type 253 was a single-engined two-seat biplane general-purpose military machine built to a 1930 government specification. It won a production contract, but this was transferred to the same company's monoplane equivalent, the Wellesley. Only one Type 253 was built.
The Hawker F.20/27 was a British fighter design built to an Air Ministry specification for an interceptor in the late 1920s. It was a single-seat biplane powered by a radial engine; the very similar but V-12-engined Hawker Fury development proved superior and only one F.20/27 was built.
The IAR 16 was a low-wing monoplane fighter designed in Romania in 1934.
