The Sopwith Cuckoo

The Sopwith T.1 Cuckoo was a British biplane torpedo bomber used by the Royal Naval Air Service (RNAS), and its successor organization, the Royal Air Force (RAF).

The T.1 was the first landplane specifically designed for carrier operations, but it was completed too late for service in the First World War.

After the Armistice, the T.1 was named the Cuckoo.

The prototype T.1 first flew in June 1917,

powered by a 200 hp Hispano-Suiza 8Ba engine.

Official trials commenced in July 1917 and the Admiralty issued production orders for 100 aircraft in August.

Contractors Fairfield Engineering and Pegler & Company had no experience as aircraft manufacturers, however, resulting in substantial production delays.
