The Avro Anson is a British twin-engine, multi-role aircraft that served with the Royal Air Force, Fleet Air Arm and numerous other air forces prior to, during, and after the Second World War. Named for British Admiral George Anson, it was originally designed for maritime reconnaissance, but was soon rendered obsolete in that role. However, it was rescued from obscurity by its suitability as a multi-engine air crew trainer, becoming the mainstay of the British Commonwealth Air Training Plan. By the end of production in 1952, the Anson spanned nine variants and a total of 8,138 were built in Britain by Avro. From 1941, a further 2,882 were built by Canadian Federal Aircraft Ltd.
