Avro Anson Mark I

The first RAF aircraft to feature a retractable undercarriage, the Avro Anson entered service with No. 48 Squadron, Coastal Command, in 1936. Anson Mk Is escorted British shipping in the North Sea and English Channel during the Battle of Britain.

The Anson's nickname was 'Faithful Annie'. It was an adaptable aeroplane and remained in production until 1952. In 2020 the RAF brought the Poseidon into service to carry out a similar maritime role. This example was used for training with the Royal Australian Air Force and was later converted for airline use.
