Twelve twin-engine, advanced training, Avro Anson Mk I were ordered in 1938. They were used by the 13th Naval Cooperation Squadron in patrol and convoy escort missions during the war in 1940 – 1941.
They formed the core of the Hellenic Air Force in the Middle East, as 5 Anson escaped to Egypt after the front in Greece collapsed. The Avro Anson Mk I continued to serve under British command, always with the 13th Naval Cooperation Squadron, until they were replaced by the Blenheim Mk IV.
