The Hawker Harrier was an experimental biplane torpedo bomber aircraft built by Hawker Aircraft to a specification issued in the 1920s for the RAF.
The Blackburn Shark was a British carrier-borne torpedo bomber built by the Blackburn Aircraft company in England. It first flew on 24 August 1933 and went into service with the Fleet Air Arm, Royal Canadian Air Force, Portuguese Navy, and the British Air Observers' School, but was already obsolescent by 1937 and in the following year, replacement by the Fairey Swordfish began.
The Handley Page Heyford was a twin-engine British biplane bomber of the 1930s. Although it had a short service life, it equipped several squadrons of the RAF as one of the most important British bombers of the mid-1930s, and was the last biplane heavy bomber to serve with the RAF. The first aircraft of the type were deployed at RAF Upper Heyford, near Bicester in Oxfordshire.
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 Blackburn B-5 Baffin biplane torpedo bomber was a development of the Ripon, the chief change being that a 545 hp (406 kW) Bristol Pegasus I.MS radial replaced the Ripon's Napier Lion water-cooled inline engine.
The Fairey Hendon was a British monoplane, heavy bomber of the Royal Air Force, designed by Fairey Aviation in the late 1920s. The aircraft served in small numbers with one Squadron of the RAF between 1936 and 1939. It was the first all-metal low-wing monoplane to enter service with the RAF.
The Short Bomber was a British two-seat long-range reconnaissance, bombing and torpedo-carrying aircraft designed by Short Brothers as a land-based development of the very successful Short Type 184.
The Handley Page H.P.54 Harrow was a British heavy bomber of the 1930s built by Handley Page and used by the Royal Air Force, being used for most of the Second World War as a transport. It was a twin-engine, high-wing monoplane with a fixed undercarriage.
The Hawker Dantorp H.B. III was a Danish single-engined biplane bomber of the 1930s. It was a development of the British Hawker Horsley designed for the Danish Navy. Two examples were built in Britain as a precursor to license production in Denmark. Financial constraints meant this was not realised and the Hawker-built examples were the only aircraft produced. They served until the German invasion of Denmark in 1940.
The Avro 571 Buffalo was a prototype British carrier-based torpedo bomber biplane, designed and built by Avro in the 1920s. It was not selected for service, the Blackburn Ripon being ordered instead.
The Handley Page H.P.24 Hyderabad was a British twin-engine biplane heavy bomber built by Handley Page which served with the Royal Air Force between 1925 and 1933. It was the last wooden heavy bomber to serve with the RAF.
The Blackburn B-3 was a prototype British torpedo bomber designed and built by Blackburn Aircraft as a potential replacement for the Ripon. It was unsuccessful, with only the two prototypes being built.
The Handley Page HP.34 Hare was a British two-seat high-altitude day bomber designed and built at Cricklewood by Handley Page. It was designed by Harold Boultbee to meet the requirements of Air Ministry Specification 23/25 for a replacement for the Hawker Horsley in the day bomber role, competing against the Blackburn Beagle, Hawker Harrier, Gloster Goring and Westland Witch. The Hare was a conventional biplane, with single-bay unequal-span staggered wings, of mixed wood and metal construction. It had a crew of two with the pilot in an open cockpit aft of the wing with a gunner/bomb aimer behind him.
The Handley Page Hanley was a British torpedo bomber aircraft of the 1920s. A single-engine, single-seat biplane intended to operate from the Royal Navy's aircraft carriers, it was not successful, with only three aircraft being built.
The Handley Page HP.14, also designated Handley Page R/200 was a prototype British naval reconnaissance aircraft of World War I, capable of operating from the decks of the Royal Navy's aircraft carriers or as a floatplane. Only three were built, the Parnall Panther being preferred.
The Vickers Type 207 was a single-engined two-seat biplane designed as a shipborne torpedo bomber to an early 1930s specification. Structurally innovative, only one was built.
The Handley Page Handcross was a single-engined biplane day bomber built to an Air Ministry specification. It was not put into production and only the three prototypes were built.
The Handley Page H.P.43 was a three-engined biplane bomber-transport built to an Air Ministry specification. It did not fly well and the biplane configuration was out-dated at completion; the only one constructed was later turned into a monoplane and led to the Handley Page H.P.54 Harrow.
The Handley Page H.P.47 was a British single-engined low-wing monoplane built to an Air Ministry specification for a general-purpose bomber and torpedo bomber aircraft. Only one was built.
The Handley Page H.P.31 was a two-seat single-engined biplane built to a British specification for a carrier-based torpedo bomber and reconnaissance aircraft. After trials, the Blackburn Ripon was preferred, though the Harrow played a significant role in the development of automatic slots.
