TheAvro 504is a single-enginebiplanebombermade by theAvro aircraft companyand under licence by others. Production duringWorld War Itotalled 8,970 and continued for almost 20 years,[2]making it the most-produced aircraft of any kind that served in any military capacity during the First World War. More than 10,000 were built from 1913 until production ended in 1932.[3][4]
Design and development
[edit]First flown fromBrooklandsbyFred "Freddie" Raynhamon 18 September 1913,[5]powered by an 80 hp (60 kW)Gnome Lambdaseven-cylinderrotary engine,the Avro 504 was a development of the earlierAvro 500,designed for training and private flying. It was atwo-bayall-wooden biplane with a square-sectionfuselage.

Operational history
[edit]Small numbers of early aircraft were purchased by theRoyal Flying Corps(RFC) and theRoyal Naval Air Service(RNAS) prior to the start of the First World War, and were taken to France when the war started. One of the RFC aircraft was the first British aircraft to be shot down by the Germans, on 22 August 1914. The pilot was2nd Lt.Vincent Waterfall and his navigatorLtCharles George Gordon Bayly (both of5 Sqn RFC)[9][10]The RNAS used four 504s to form a special flight to bomb theZeppelinworks atFriedrichshafenon the shores ofLake Constance.Three set out fromBelfortin north-eastern France on 21 November 1914, carrying four 20 lb (9 kg) bombs each. While one aircraft was shot down, the raid was successful, with several direct hits on the airship sheds and the destruction of the hydrogen generating plant.[11]
Soon obsolete as a frontline aircraft, it came into its own as a trainer, with thousands being built during the war, with the major production types being the 504J and the mass production 504K, designed with modified engine bearers to accommodate a range of engines to cope with engine shortages. 8,340 Avro 504s had been produced by the end of 1918.[12]
In the winter of 1917–18 it was decided to use converted 504Js and 504Ks to equip Home Defence squadrons of the RFC, replacing ageingB.E.2cs,which had poor altitude performance. These aircraft were modified as single-seaters, armed with a Lewis gun above the wing on aFoster mounting,and powered by 100 hp (75 kW) Gnome or 110 hp (82 kW) Le Rhône engines. 274 converted Avro 504Js and Ks were issued to eight home defence squadrons in 1918, with 226 still being used as fighters at the end of the First World War.[13]
Following the end of the war, while the type continued in service as the standard trainer of theRAF,large numbers of surplus aircraft were available for sale, both for civil and military use. More than 300 504Ks were placed on the civil register in Britain. Used for training, pleasure flying, banner towing and evenbarnstormingexhibitions (as was ongoing in North America following World War I with the similar-role, surplusCurtiss JN-4sandStandard J-1s); civil 504s continued flying in large numbers until well into the 1930s.
The embryonicair service of the Soviet Union,formed just after the First World War, used both original Avro 504s and their ownAvrushka( "Little Avro" ) copy of it for primary training as theU-1in the early 1920s, usually powered by Russian-made copies of theGnome Monosoupaperotary engine. This Russian version of the 504 was replaced by what would become the most produced biplane in all of aviation history, thePolikarpov Po-2,first known as theU-2;the type remained in Soviet service till the late 1920s, and much later elsewhere.
Although Avro 504s sold to China were training versions, they participated in battles amongwarlordsby acting as bombers with the pilot dropping hand grenades and modified mortar shells[citation needed].
The improved, redesigned and radial-engined 504N with a new undercarriage was produced by Avro in 1925. After evaluation of two prototypes, one powered by theBristol Luciferand the other by theArmstrong-Siddeley Lynx,the Lynx-powered aircraft was selected by the RAF to replace the 504K. 592 were built between 1925 and 1932, equipping the RAF's five flying training schools, while also being used as communication aircraft. The 504N was also exported to the armed forces of Belgium, Brazil, Chile, Denmark, Greece, Siam and South Africa, with licensed production taking place in Denmark, Belgium, Canada, Siam and Japan.
The RAF's 504Ns were finally replaced in 1933 by theAvro Tutor,with small numbers continuing in civilian use until 1940, when seven were impressed into RAF service, where they were used for target- and glider-towing.
The 504 was the first British aeroplane to strafe troops on the ground[14]as well as the first British aircraft to make a bombing raid over Germany.[2][15]It was also the first Allied aeroplane to be downed by enemyanti-aircraftfire and was the first aircraft flown by many future aces, includingBilly Bishop.
The 504 is easily recognisable because of the single skid between the wheels, referred to as the "toothpick" in the RAF.[citation needed]
