The de Havilland DH.65 Hound was a 1920s British two-seat day bomber built by de Havilland at Stag Lane Aerodrome.
The Airco DH.1 was an early military biplane of typical "Farman" pattern flown by Britain's Royal Flying Corps during World War I. By the time the powerplant for which it was designed was sufficiently plentiful it was obsolete as an operational aircraft, and apart from a few examples sent to the Middle East it served as a trainer and Home Defence fighter.
The de Havilland DH.14 Okapi was a British two-seat day bomber of the 1910s built by de Havilland. The aircraft was designed as an Airco DH.4 and DH.9 replacement, but it never entered production.

The Bristol Boarhound was a British army cooperation and liaison aircraft of the 1920s. It was a two-seat biplane with wings of equal span, of steel frame construction with fabric covering.
The Vickers Vixen was a British general-purpose biplane of the 1920s. Designed and developed by Vickers in a number of variants, with 18 Vixen Mark V sold to Chile. A prototype of a version with metal wings was built as the Vickers Vivid. The Vixen also formed the basis of the closely related Venture and Valparaiso aircraft, which were also built and sold in small numbers in the 1920s
The Sopwith B.1 was an experimental British bomber aircraft of the First World War. A single-seat, single-engined biplane, the B.1 was built by the Sopwith Aviation Company for the Royal Navy. Although only two were built, one was used for bombing raids over France.
The Nieuport London was a British night bomber aircraft designed in the First World War. A twin-engined triplane, the London was dogged by the unavailability and unreliability of its engines, and did not fly until 1920. Only two were built.
The Boulton & Paul P.7 Bourges was a prototype British twin-engined biplane day bomber built by Boulton & Paul to replace the Airco DH.10 Amiens. Despite demonstrating excellent performance and manoeuvrability, only three prototypes were built, post World War I cost cutting leading to the DH.10 not being replaced.
The de Havilland DH.56 Hyena was a prototype British army cooperation aircraft of the 1920s. A single-engined biplane, the Hyena was designed against an RAF requirement, but was unsuccessful with only two being built, the Armstrong Whitworth Atlas being preferred.
