When it entered service with No.48 Squadron at RAF Manston in March 1936, the Avro Anson became the first monoplane type to achieve squadron service status and was also the first RAF aircraft to feature a retractable undercarriage. 

The RAF Anson Mk.I was equipped with a fixed forward firing .303 machine gun operated by the pilot and a single Lewis gun mounted in the manually traversed dorsal turret. It could also be equipped with a modest bomb load, something which was required by submarine hunting aircraft operated by Coastal Command. 

Despite the RAF entering the Second World War with 26 squadrons equipped with Avro Ansons, they were basically obsolete as a fighting machine and were quickly withdrawn to secondary training roles, a task for which the ‘Faithfull Annie’ was particularly well suited. 

As part of the Empire Air Training Scheme, many thousands of aircrew destined for service with Bomber Command were trained both in the UK and overseas.
