The most recent aircraft to join the Army Historic Aircraft Flight (AHAF) was the De Havilland Chipmunk T10, WD 325. The Chipmunk holds many fond memories for all Army pilots, as it was this type that was used as the basic trainer on all Army pilot courses since the early 1950s. WD325 was one of the first aircraft to be delivered to Middle Wallop in 1953.

At its peak the School of Army Aviation, now the Army Aviation Centre (AACen), operated 21 aircraft and these were in daily use prior to their out-of-service date of March 1997.

The Chipmunk holds many fond memories for all Army pilots, as it was this type that was used as the basic trainer on all Army pilot courses since the early 1950s. Initially the Royal Air Force (RAF) was responsible for training Air Observation Post (AOP) pilots and the original aircraft were furnished in the standard RAF Training Command markings of silver with a yellow band. However, it was not until the formation of the Army Air Corps on 1 September 1957 that the markings reflected the familiar red and white colour scheme.

The Chipmunk T10 was popular as a trainer as it was easy to handle on the ground as well as in the air.
