SSP class airship

In 1916, design commenced at RNAS Kingsnorth on an SS class -type airship that would have a more comfortable purpose-built car, and not simply be an adaptation of an aeroplane fuselage. The SSP cars were of rectangular cross-section, had a blunt nose, and could accommodate a crew of three. As the name suggests, the SSP was powered by a Green engine mounted on bearers to the rear of the car, powering a diameter four-bladed propeller in pusher configuration. Four examples of the type were later fitted with Rolls-Royce Hawk engines. but because of the success of the SSZ type it was decided that these would become the standard SS variant, and the SSP programme was terminated. ==Operators==
