Sikorsky
The Sikorsky Aircraft Corporation is an American aircraft manufacturer based in Stratford, Connecticut. It was established by Igor Sikorsky in 1923 and was among the first companies to manufacture helicopters for civilian and military use.
On May 23, 1923 the "Sikorsky Aero Engineering Corporation" was founded near Roosevelt Field, New York, by Igor Sikorsky, an immigrant to the United States who was born in Kiev. In 1925 the company name was changed to "Sikorsky Manufacturing Company". In 1929 the company moved to Stratford, Connecticut, and became part of the United Aircraft and Transport Corporation (UATC) in July of that year (under the name of Sikorsky Aircraft Corporation?).
After the Air Mail scandal of 1934, the U.S. government concluded that such large holding companies as UATC were anti-competitive, and new antitrust laws were passed forbidding airframe or engine manufacturers from having interests in airlines. So UATC broke into three separate companies. Its manufacturing interests east of the Mississippi River (Pratt & Whitney, Sikorsky, Vought, and Hamilton Standard Propeller Company) were organized as the United Aircraft Corporation (now United Technologies Corporation (UTC)), headquartered in Hartford. The western manufacturing interests (including Northrop Aviation Corporation, formerly Avion Corporation), were folded into the Boeing Airplane Company, headquartered in Seattle. And United Airlines became a separate company.
Igor Sikorsky originally concentrated on the development of multi-engined landplanes and then amphibious aircraft. In the late 1930s, sales declined and United Aircraft merged his division with Vought Aircraft. He then began work on developing a practical helicopter. After first flying the VS-300 he developed the Sikorsky R-4, the first stable, single-rotor, fully controllable helicopter to enter full-scale production in 1942, upon which most subsequent helicopters were based.
On July 20, 2015, Lockheed Martin announced an agreement to purchase Sikorsky from UTC for $9.0 billion. Final approval (from the Chinese government) came in November 2015. The sale was completed on November 6, 2015.
