Avro 685 York

1st Flight 1942

The Avro York was a British transport aircraft developed during the Second World War.

The design was derived from the Avro Lancaster heavy bomber, several sections of the York and Lancaster being identical.

Due to the importance of Lancaster production, York output proceeded at a slow pace until 1944, after which a higher priority was placed upon transport aircraft.
