The Short Seaford developed the Sunderland around four Bristol Hercules engines, a 20 mm dorsal turret, Browning machine guns, and a bomb or depth-charge load of about two and a quarter tons. Its 2,700-nautical-mile range suited search and patrol, although the aircraft was used more for moving personnel and maintaining communications than for anti-submarine attack. Entering service late in 1944 left little time for wartime employment. The type also became entangled in postwar service politics. The Navy could point to operating the Walrus while the RAF controlled long-range maritime flying boats, and the Seaford disappeared by 1950. Its technical capabilities did not guarantee a lasting place once service ownership and postwar priorities entered the decision.

Seaford: a heavily armed Sunderland successor
The Short Seaford added more powerful engines and heavier armament to the Sunderland design, then arrived late enough that transport and communications outweighed its wartime combat use.
