The SSP (Submarine Scout Pusher) were a class of Royal Navy non-rigid airship or "blimp" developed by the United Kingdom during World War I as a successor to the earlier SS class airship.
Found to be inferior to a parallel development, the Submarine Scout Zero non-rigid, only a few were built.
The main role of these craft was to escort convoys and scout or search for German U-boats.
[1] In 1916, design commenced at RNAS Kingsnorth on an SS class -type airship that would have a more comfortable purpose-built car,[2] and not simply be an adaptation of an aeroplane fuselage.
[3] Six SSPs entered service between January and June 1917,[4] 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.
