variants with their own articles =The Hawker Harrier was an experimental biplane torpedo bomber aircraft built by
Hawker Aircraft to a specification issued in the1920s for theRAF .Development
In avyear|1925, the British air ministry laid down specifications for a high altitude bomber to replace the
Hawker Horsley and for a coastal torpedo bomber (Specifications 23/25 and 24/25). As these specifications were similar, the Air Ministry announced that a single competition would be held to study aircraft submitted for both specifications. Mason 1994, p.193.Sydney Camm ofHawker Aircraft designed the Harrier to meet the requirements of Specification 23/25, with the prototype ("J8325") first flying in February avyear|1927, the first of the competitors to the two specifications to . The Harrier was a two seat biplsne with single bay wings powered by a gearedBristol Jupiter VIII. It was armed with oneVickers machine gun and oneLewis gun carrying a maximum of 1,000 lb (~500 kg) of bombs. Lewis 1980, p.162.]The prototype Harrier was tested at the Aeroplane and Armament Experimental Establishment (A & AEE) at Martlesham Heath in November 1927, where, while it met the requirements of Specification 23/25, and had satisfactory handling, the geared engine meant that it was underpowered, and it had an inferior bombload to the Hawker Horsley, the aircraft it was meant to replace. It was therefore modified to carry a torpedo. On testing the modified aircraft, however, it was found to still be underpowered, being incapable of taking off with torpedo, gunner and a full fuel load. It was therefore not considered further, the competition ultimately being won by the
Vickers Vildebeest . Mason 1994, p.200.]The prototype was used by Bristol as an engine testbed, flying with the 870 hp
Bristol Hydra and the 495 hp Bristol Orion engines.pecifications (Harrier (Bomber))
