|Role||Single-seat Flying Boat|
|National origin||United Kingdom|
The Pemberton-Billing P.B.1,[nb 1] sometimes known as the "Supermarine", was a 1910s British single-seat flying-boat built by Pemberton-Billing Limited, which later became the Supermarine Aviation Works. Only one P.B.1 was built, and it never flew any distance further than a hop.
Design and development
The P.B.1 was a single-seat open cockpit biplane powered by a 50 hp (36 kW) Gnome rotary engine driving a three-bladed pusher propeller, which was mounted in a tractor configuration nacelle between the upper wings and the fuselage. It had a single-step hull designed by the naval architect Linton Hope, with a spruce skin over a mahogony structure, and covered with waterproof fabric. It had two-bay wings constructed of spruce and Ash, with ailerons on the upper wing and floats under the lower wingtips. The pilot sat in a cockpit aft of the wing trailing edge.
Described as "a boat that will fly, [instead of] an aeroplane that will float", only one P.B.1 was built; the prototype was displayed at the Olympia Aero Show in March 1914. It was rebuilt during April 1914, with the pilot's cockpit moved forward to the nose of the aircraft, and the Gnome engine mounted on top of the fuselage, driving two 3-bladed pusher propellers via chain drives. Following the modifications, the P.B.1 entered testing, but failed to achieve flight during testing on Southampton Water on 30 May 1914. Noel Pemberton Billing, the head of Pemberton-Billing Limited and designer of the PB.1, claimed that the aircraft made a short hop during June, but other sources state that the PB.1 never flew.

- Pemberton Billing aircraft underwent a retrospective redesignation in 1916, with the original P.B.1 design, as displayed at Olympia, redesignated P.B.7, and the modified aircraft as tested during May–June 1914 redesignated P.B.9. The P.B.9 landplane scout, which was built in August 1914 using the engine of the P.B.1 became the P.B.13 as part of the same redesignation.
