Airbus Hamburg-Finkenwerder, also known as Hamburg Finkenwerder Airport , is an aircraft manufacturing plant and associated private airport in the Finkenwerder quarter of southwest Hamburg, Germany. The airport is an integral part of the Airbus-owned plant, and is exclusively used by that company for corporate, freight, test, and delivery flights, including those of the former Airbus A380. In 1933, the Blohm & Voss shipbuilding company in Hamburg decided to diversify into aircraft manufacture, believing that there would soon be a market for all-metal, long-range flying boats, especially with the German state airline Deutsche Luft Hansa. It also felt that its experience with all-metal marine construction would prove an advantage. In order to do this, it created the Hamburger Flugzeugbau (HFB) as a subsidiary company. Initially manufacturing was carried out at the Blohm & Voss shipbuilding works, with an inland airfield and final assembly building for landplanes at Wenzendorf Aircraft Factory. In 1937, the HFB was reconstituted as a operating division of Blohm & Voss rather than as a separate company, and the Finkenwerder aircraft works and associated airfield were established in 1939 by this division. The works were substantially undamaged during World War II, and when manufacturing was revived there, using the previous HFB company identity, the facilities began a long series of progressive expansions and modernizations. During the Berlin Airlift, detachments from both No. 201 Squadron RAF and No. 230 Squadron RAF flew Short Sunderland V's. In 1964, both the HFB 320 Hansa Jet and the third prototype Transall C-160 made their first flights from the airport. Through a series of mergers and acquisitions, HFB and its Finkenwerder facility eventually became part of Airbus. Between April 2006 and July 2007, the runway was extended at the southern end, increasing its length from 2,684 m to 3,183 m, in order to accommodate the planned freight version of the Airbus A380. The foundations of the Fink II submarine pen are extant, just east of the north end of the runway.
