The British were the first to undertake a successful attack by aerial torpedo: in the Aegean Sea using a Short Type 184 in 1915. The late-war Sopwith T.1 was specially designed to be used as a embarked torpedo bomber. Built as a single-seater due to the weight of the torpedo, the Cuckoo was of typical and proven no-nonsense Sopwith construction methods.
Too late to take part in the Great War, they served honorably postwar being well-loved by their crews, specially the Wolseley Viper-engined Cuckoo II.
Very cute -I know, what an adjetive- drawing of how to aim a “tin fish” with a Cuckoo.
