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,[3] 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 mahogany 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.[4][5]
Described as "a boat that will fly, [instead of] an aeroplane that will float",[3] only one P.B.1 was built;[3] the prototype was displayed at the Olympia Aero Show in March 1914.[3] 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.[6] 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,[6] but other sources state that the PB.1 never flew.[7][8]
Following the conclusion of the attempted flight testing, the P.B.1 was dismantled on 28 July 1914, with its engine being used in the Pemberton-Billing P.B.9 single seat scout aircraft.[1]

Notes
- 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.[1] 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.[2]
