They were developed in parallel with the 35-metre long Fairmile D motor torpedo boats ("dog boats"), specifically due to the need to hunt down German E-boats at a time of scarcity of suitable diesel engines. While sixty were planned, only an initial batch of nine were ordered on 8 November 1940, of which seven were completed.
