bomber design, the Supermarine B.12/36 which was replaced by the Short Stirling. After the end of the war, the Supermarine division built the Royal Navy's first jet fighter, the Attacker, developed from the final Spitfire type. It served front line squadrons aboard aircraft carriers and RNVR squadrons at shore bases. The Attacker was followed by the more advanced Swift which served in the fighter and photo-reconnaissance roles. The last of the Supermarine aircraft was the Scimitar. In the shakeup of British aircraft manufacturing, Vickers-Armstrongs (Aircraft) became a part of the British Aircraft Corporation and the individual manufacturing heritage names were lost. History Founding In 1909 the British Noel Pemberton-Billing purchased a number of engineering workshops on of land at South in Sussex which he intended to develop as an airfield. At the same time, he built a number of unsuccessful aircraft of his own design. To promote the venture, he founded his own magazine Aerocraft. Despite attracting some aircraft constructors, the airfield venture failed within a year and about the same time he sold Aerocraft. In 1911, Pemberton-Billing purchased facilities to provide a base for a motor launch and yacht trading business at White's Yard off Elm Road (later renamed Hazel Road) on the River Itchen, upstream of Woolston, Southampton. To manage the business, Pemberton-Billing hired his friend Hubert Scott-Paine, whom he had first met while involved in property speculation in Shoreham, Kent. Pemberton-Billing, his wife and Scott-Paine lived on Pemberton-Billing's yacht Utopia. Under Scott-Paine's management the business was soon profitable, which allowed Billing (with the assistance of Scott-Paine) to design a series of flying boats with detachable propeller and wings so that with them removed it could be used as a motor launch. Pemberton-Billing submitted a patent application for his design in October 1913. After obtaining his aviator's certificate on 17 September 1913 following a £500 bet with Frederick Handley-Page that he could obtain it within 24 hour of commencing flight training, he decided to build his own aircraft. In partnership with Alfred Delves de Broughton, Billing established Pemberton-Billing Ltd on 27 June 1914 with capital of £20,000. Billing had 6,800 shares, Broughton 3,700 and works engineer Lorenz Hans Herkomer (1889–1922), 500. Herkomer's background was in electrical engineering and automobiles. Rumanian Carol Vasilesco was employed to prepare drawings and undertake the detailed design of airframes. On land at Oakbank Wharf on the river Itchen in Woolston, Southampton that Billing
