This requirement was laid down in <a href="http://en.wikipedia.org/wiki/List_of_Air_Ministry_Specifications" target="_blank">Specification F9/26</a>. The Bulldog was designed by <a href="http://en.wikipedia.org/wiki/Frank_Barnwell" target="_blank">Frank Barnwell</a>, the Chief Designer of the Bristol company, (who had served as a Captain in the <a href="http://en.wikipedia.org/wiki/British_Army" target="_blank">British Army</a> during the <a href="http://en.wikipedia.org/wiki/World_War_I" target="_blank">First World War</a>), as a private venture to meet the requirements of this specification. The prototype Bulldog, the Bulldog Mk. I first flew on 17 May 1927.<a href="http://en.wikipedia.org/wiki/Bristol_Bulldog#cite_note-Mason-0" target="_blank">[1]</a> After initial consideration of all the types entered to meet the specification, the Bulldog and the <a href="http://en.wikipedia.org/wiki/Hawker_Hawfinch" target="_blank">Hawker Hawfinch</a> were selected for more detailed evaluation.<a href="http://en.wikipedia.org/wiki/Bristol_Bulldog#cite_note-Mason-0" target="_blank">[1]</a> While the Bulldog's manoeuvrability and strength were praised by the RAF,<a href="http://en.wikipedia.org/wiki/Bristol_Bulldog#cite_note-Barnes-1" target="_blank">[2]</a> it initially had poor spinning recovery properties and was therefore fitted with a lengthened rear fuselage. In this form, it was declared the winner of the competition, having slightly superior speed<a href="http://en.wikipedia.org/wiki/Bristol_Bulldog#cite_note-Barnes-1" target="_blank">[2]</a> and was easier to maintain,<a href="http://en.wikipedia.org/wiki/Bristol_Bulldog#cite_note-Barnes-1" target="_blank">[2]</a> and required fewer changes to produce an operational aircraft than the Hawfinch.<a href="http://en.wikipedia.org/wiki/Bristol_Bulldog#cite_note-Mason-0" target="_blank">[1]</a> The full-production Bulldog came in the form of the Mk.II, which had a modified structure but in every other respect was identical to the original Bulldog; having two 0.303 in (7.7 mm) Vickers machine guns; a <a href="http://en.wikipedia.org/wiki/Hardpoint" target="_blank">capacity</a> for four 20 lb (9 kg) bombs; a 450 hp (336 kW) <a href="http://en.wikipedia.org/wiki/Bristol_Jupiter" target="_blank">Bristol Jupiter</a> radial engine; giving the Bulldog a maximum speed of just under 180 mph (290 km/h) and a range of 300 miles (480 km). The aircraft then entered production in 1928, entering service the following year, and becoming, during the early 1930s, the most widely used aircraft in the RAF. It was cheap to maintain and thus, at a time of defence budget constraints, was the more preferable option to any other competitors. The Mk. IIA was again virtually similar to its predecessor, though it had a new Jupiter engine and a strengthened structure.  <a href="http://en.wikipedia.org/wiki/Image:Bristol_Bulldog_REJS.jpg" target="_blank"><img src="http://upload.wikimedia.org/wikipedia/commons/thumb/8/8d/Bristol_Bulldog_REJS.jpg/180px-Bristol_Bulldog_REJS.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>  <a href="http://en.wikipedia.org/wiki/Image:Bristol_Bulldog_REJS.jpg" target="_blank"><img src="http://en.wikipedia.org/skins-1.5/common/images/magnify-clip.png" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> A Bristol Bulldog preserved at the <a href="http://en.wikipedia.org/wiki/Royal_Air_Force_Museum" target="_blank">RAF Museum</a>, Hendon   The Bulldog proved to be quite a successful export to foreign air forces, seeing service with <a href="http://en.wikipedia.org/wiki/Australia" target="_blank">Australia</a>, <a href="http://en.wikipedia.org/wiki/Denmark" target="_blank">Denmark</a>, <a href="http://en.wikipedia.org/wiki/Estonia" target="_blank">Estonia</a>, <a href="http://en.wikipedia.org/wiki/Finland" target="_blank">Finland</a>, <a href="http://en.wikipedia.org/wiki/Japan" target="_blank">Japan</a>, <a href="http://en.wikipedia.org/wiki/Latvia" target="_blank">Latvia</a>, <a href="http://en.wikipedia.org/wiki/Siam" target="_blank">Siam</a>, <a href="http://en.wikipedia.org/wiki/Spain" target="_blank">Spain</a> and <a href="http://en.wikipedia.org/wiki/Sweden" target="_blank">Sweden</a>. The Bulldog was withdrawn from RAF service in 1937, being replaced by the <a href="http://en.wikipedia.org/wiki/Hawker_Hurricane" target="_blank">Hawker Hurricane</a> and <a href="http://en.wikipedia.org/wiki/Supermarine_Spitfire" target="_blank">Supermarine Spitfire</a>, both of which would become legends of the RAF for their contributions during the <a href="http://en.wikipedia.org/wiki/World_War_II" target="_blank">Second World War</a>. The Bristol Bulldog's career was not over though, for the type continued to serve with other air forces.Operational history The Bulldog never saw combat service with the RAF, though during the <a href="http://en.wikipedia.org/wiki/Abyssinia_Crisis" target="_blank">Abyssinia Crisis</a> of 1935-36, Bristol Bulldogs were sent to the <a href="http://en.wikipedia.org/wiki/Sudan" target="_blank">Sudan</a> to reinforce <a href="http://en.wikipedia.org/wiki/Middle_East_Command" target="_blank">Middle East Command</a>. <a href="http://en.wikipedia.org/wiki/Douglas_Bader" target="_blank">Douglas Bader</a>, better known for his Second World War actions, lost both of his legs when his Bristol Bulldog crashed while he was performing unauthorised flying <a href="http://en.wikipedia.org/wiki/Aerobatics" target="_blank">acrobatics</a>. A number of Bulldogs, ex-Latvian aircraft, saw service during the <a href="http://en.wikipedia.org/wiki/Spanish_Civil_War" target="_blank">Spanish Civil War</a>, as part of the forces fighting the Nationalists. Nineteen Bulldogs also saw combat as part of the <a href="http://en.wikipedia.org/wiki/Finnish_Air_Force" target="_blank">Finnish Air Force</a> during the <a href="http://en.wikipedia.org/wiki/Winter_War" target="_blank">Winter War</a> against the <a href="http://en.wikipedia.org/wiki/Soviet_Union" target="_blank">Soviet Union</a>, which began in 1939. The Bulldogs fought well against their Soviet opponent, gaining six kills by five pilots for the loss of one of their own,<a href="http://en.wikipedia.org/wiki/Bristol_Bulldog#cite_note-FAF_in_Color-2" target="_blank">[3]</a> the types shot down being two <a href="http://en.wikipedia.org/wiki/Polikarpov_I-16" target="_blank">Polikarpov I-16s</a> and four <a href="http://en.wikipedia.org/wiki/Tupolev_SB-2" target="_blank">Tupolev SB-2s</a>,<a href="http://en.wikipedia.org/wiki/Bristol_Bulldog#cite_note-FAF_in_Color-2" target="_blank">[3]</a> both of which were quite superior in terms of technology compared to the Bulldog. In fact, the very first aerial victory of <a href="http://en.wikipedia.org/wiki/Finnish_Air_Force" target="_blank">Finnish Air Force</a> was achieved by a Bulldog piloted by SSgt Toivo Uuttu on 1 December 1939.<a href="http://en.wikipedia.org/wiki/Bristol_Bulldog#cite_note-Finnish_biplane_fighter_aces_-_Toivo_Uuttu-3" target="_blank">[4]</a> The Bulldog continued in service during the subsequent <a href="http://en.wikipedia.org/wiki/Continuation_War" target="_blank">Continuation War</a> against the Soviet Union, though without scoring any further kills or suffering losses.</blockquote>
