The Auster was a twice-removed development of an American Taylorcraft design of civilian aircraft, the Model A. The Model A had to be redesigned in Britain to meet more stringent Civil Aviation standards and was named the Taylorcraft Plus C.[1][2] After the start of the Second World War, the company developed the model further as an air observation post (AOP)—flown by officers of the Royal Artillery and used for directing artillery fire of British Army Royal Artillery units.
Prewar Taylorcraft C/2, impressed by the RAF in September 1941, seen postwarAuster I converted postwar to Taylorcraft Plus D, restored in wartime markings as LB382 of 653 Squadron RAF
The Plus C was re-engined with the Blackburn Cirrus Minor I engine and was re-designated as the Taylorcraft Plus D. Most of the civil Plus Cs and Ds were impressed into Royal Air Force service, the Plus Cs were re-engined with the Cirrus Minor I and re-designated as Plus C2.
Pre-war tests identified the Taylorcraft Model D as the most suitable aircraft for the AOP role. Three more Ds were purchased from Taylorcraft and a trials unit, D Flight, under Major Charles Bazeley RA, formed at Old Sarum on 1 February 1940. The flight with three Austers and one Stinson 105, and three artillery and one RAF pilots, moved to France where they trained with artillery and practiced fighter avoidance with Hurricanes of Air Component before moving south to train with French artillery. The flight did not participate in the fighting and withdrew without loss to the UK. However, the War Office then ordered 100 Stinson L-1 Vigilants. Formation of the RAF's Army Cooperation Command in December 1940 led to the RAF rejecting the very notion of light AOP aircraft.
Intercession by General Alan Brooke led to an accommodation that led to the first AOP pilot course for artillery officers taking place in October 1940 and in 1941, the first AOP squadron, No 651, formed. Stinson Vigilants eventually arrived in early 1942 but most had been severely damaged in transit leading to the adoption of the Taylorcraft Auster 1 and an order for 100 aircraft placed. Some of the Stinsons were resurrected but found to be too big for the AOP role.[3]
The Auster II was a re-engined aircraft with an American 130 hp (97 kW) Lycoming O-290 engine. Due to the shortage of American engines that version was not built but led to the Auster III (Model E), which was the same as the Auster I but had a 130 hp (97 kW) de Havilland Gipsy Major engine. The next development was the Auster IV (Model G) which had a slightly larger cabin with three seats and used the Lycoming O-290. The major production version was the Auster V (Model J) which was an Auster IV with blind flying instruments, and a conventional trimmer design.[4][5]
Post war, the Auster Mark V was used as the basis for the Auster J/1 Autocrat intended for the civilian market; the British firm having changed their name to Auster and stopped licensing from Taylorcraft. Further military aircraft were supplied post war; the Auster AOP6, Auster T7 (a trainer), and the Auster AOP9.
Operational history
The Auster Mark III, IV and V were issued to 12 RAF, one Polish and three Royal Canadian Air Force (RCAF) air observation post (AOP) Squadrons. The first to deploy was No. 651 Squadron RAF. The leading elements landed in Algiers on 12 November 1942 with eight aircraft, 11 Royal Artillery (RA) pilots, 39 RA soldiers and 25 airmen (mostly maintenance technicians). The normal strength of an AOP squadron was 12 aircraft, 19 RA officers (all pilots), 83 RA other ranks and 63 RAF including two administrative officers. Aircraft were fitted with the Army's No 22 Wireless, an HF set providing two-way voice communications with artillery units and formations on the ground.
No. 664 Squadron RCAF, No. 665 Squadron RCAF, and No. 666 Squadron RCAF were also issued with the Auster Mk. IV and V, formed in the UK at RAF Andover in late 1944 and early 1945. The RCAF squadrons were manned by Canadian personnel of the Royal Canadian Artillery and the RCAF, with brief secondment to the squadrons with pilots from the Royal Artillery; control was maintained in the UK by 70 Group, RAF Fighter Command. The three squadrons deployed from RAF Andover, England, to the Netherlands, to Dunkirk in France, where the last Canadian 'shots' in Europe were fired, and later to occupied Germany. No. 656 Squadron RAF was assigned to 14th Army and used Austers in Burma, generally with flights assigned to each corps. In European theatres a squadron was generally assigned to each corps, but under command for technical matters of an RAF group.
Postwar Auster AOP aircraft were reorganised into independent flights (probably because the RAF used Wing-Commanders, equivalent to Lieutenant-Colonels, to command squadrons while the army insisted on a major's command) including 1903 Flight in Korea that had artillery pilots from several Commonwealth countries. There was also an Auster-equipped Liaison Flight, No 1913, in that theatre. Air OP flights also operated in the Malayan Emergency. Several AOP squadrons were reformed within the Royal Auxiliary Air Force in 1949 and these operated some AOP.5s, AOP.6s and AOP.9s until at least March 1957, when the Auxiliary Air Force was disbanded. All Auster AOP units were transferred to the Army Air Corps when it was formed in September 1957, with AAC squadrons using numbers starting with 651. The air observation duties, counter-insurgency and casualty evacuation roles performed by Auster and similar light aircraft were generally taken over by light helicopters from the mid-1960s.
Several Taylorcraft Austers formed, with other civil light aircraft, part of the initial equipment of the Sherut Avir, formed in November 1947 as the air component of the Jewish paramilitary organisation Haganah, which later became part of the Israeli Air Force. They were supplemented early in 1948 by six ex-RAF Austers that had been assembled from hulks of 25 aircraft purchased as scrap. These aircraft formed the core of Israel's air force in the early part of the 1947–1949 Palestine war, being used for reconnaissance and resupply missions, while also being used to drop home-made bombs on Arab forces.[7]
