The Short Sunderland Mk I is the initial production variant of the RAF's primary maritime patrol flying boat of World War II, derived from the Empire class airliner and powered by Bristol Pegasus XXII engines. It entered service in 1938 and earned the German nickname 'Flying Porcupine' for its defensive armament.

History

Short Brothers flew the Sunderland prototype in October 1937, and Mk I deliveries to RAF Coastal Command began in June 1938. The type was immediately tasked with convoy escort and anti-submarine patrols in the Atlantic. Blackburn Aircraft produced additional airframes to meet wartime demand.

Variants

The Mk I with Pegasus XXII engines was followed by the Mk II with Pegasus XVIII and ASV radar, then the longer-range Mk III with flush hull steps, and the Mk V with Pratt & Whitney Twin Wasps.

Where you'll see it

Served with RAF Coastal Command from 1938, and also with Royal Australian, New Zealand, South African, and Canadian air forces throughout the war and into the 1950s.
