Airspeed AS10 Oxford

A British Commonwealth Aircrew Navigational and Radio Communications Trainer during World War II.

Airspeed Oxford 1 (AS592)

During the late 1930's, the Airspeed Envoy was developed by Airspeed to meet the requirements of Specification T.23/36. The result was the Airspeed AS10 Oxford which was used for pilot and navigation / radio operator training and brought large scale production success to Airspeed.

The 3-seat, cantilever monoplane saw great success as one of the RAF's most versatile trainers. In its dual control / 2 front-seat configuration it was a stable and reliable pilot-trainer and with one seat pushed back and a set of controls removed, it was easily adapted for both 'prone bomb-aimer' training as well as a superb aerial photography platform. The 3rd seat could also be pushed back to easily align with the chart table for advanced navigator instruction, as well as providing wireless operator access.

In addition to its training role, the Oxford was also pressed into service as a Transport Ambulance.

The prototype (L4534) flew from the Airspeed airfield at Portsmouth for the first time on 19th June 1937 and the type remained in RAF service until 1954. Nicknamed the 'Ox-box', the Oxford was the preferred trainer for the Empire Air Training Scheme (EATS) and the British Commonwealth Air Training Plan (BCATP) which sent thousands of airmen to Canada to train on Oxfords.

Sadly, one dark episode for the Oxford was in 1941 when the much celebrated aviatrix Amy Johnson went The first Christchurch built Oxford was (X6250) flew in March 1941.

Ultimately, some 8,751 were ordered with 4,411 being built by Airspeed at Portsmouth and 550 at Christchurch. These were supplemented by production by De Havilland at Hatfield (1,515), Percival Aircraft at Luton (1,525) and Standard Motors at Coventry (750).

Airspeed Oxford Production at Portsmouth during 1941

It is reported that 165 aircraft were cancelled and not built, giving a total of 8,586 completed.

Mr Alan Butler (Chairman of both Airspeed and De Havilland) stated at the Airspeed 1946 Ordinary General Meeting that 'the peak production rate of the Oxford was an astonishing seventy-five per month in the spring of 1942'.

After the war, 152 suplus aircraft were converted to the AS.65 Consul, a 6-seat commercial aircraft, whilst a number of remaining Oxford's were purchased by the Hellenic Air Force and saw service by the RHAF during the Greek Civil War between 1946 and 1949.

The Oxford continued with a number of overseas air forces although it was finally retired from the RAF in 1956.
