An impression of what the completed S.S.1 may have looked like while moored and in military colours. It bears serial N1293, one of a batch of serials (N1290 to N1299) set aside for Supermarine-built AD flying-boats, but of which only N1290 was completed. The remaining serials were cancelled in March 1918.

A series of illustrations from the Supermarine brochure of 1919 depicting the S.S.1, with drawings of the proposed machine in flight, after ‘‘Dropping the Planes” and “Ready for Packing on Submarine Deck”. Although it was included in the 1919 brochure, the S.S.1 has largely been forgotten in subsequent histories of the company.

Noel Pemberton Billing submitted his first patent application for the "slip-wing" system in late 1913, and supplemented this with additional ideas in 1914. The two layouts seen here incorporate elements developed for the proposed P.B.7 and "P.B.31”/S.S.1 (P.B.31 was allocated to the Nighthawk quadruplane).

The 15ft (4-57m)-long hull of the S.S.1 minus its wings, square-section boom and empennage. The flying-control mechanisms are shown, as is the position of the six-cylinder liquid-cooled engine in the rear section, which powered a chain-drive connected to the propeller mounted at the forward end of the empennage boom.

SUPERMARINE S.S.1. This three-view of the Supermarine S.S. 1 SingleSeat Bomber has been compiled from company blueprints, drawings and sketches. The equal-span single-bay unstaggered biplane wings were of 32ft (9-75m)-span. Technical details of the quick-release system remain undiscovered.
