Focke-Wulf, formerly known as Bremer Flugzeugbau, was an aerospace manufacturer in Germany that produced both civil and military aircraft before and during World War II. The company’s fighter aircraft designs were often modified versions of the Focke-Wulf Fw 190. Focke-Wulf merged with Albatros Flugzeugwerke in 1931, and Kurt Tank, a former engineer and test pilot for Albatros, became head of the technical department. The company went through various leadership changes and financial injections throughout its history, including increasing shareholding from HAG combine and C. Lorenz AG. Focke-Wulf is also known for producing the Fw 200 airliner, which made a nonstop flight between Berlin and New York City in August 1938. The Fw 190 Würger, produced from 1941-1945, was the mainstay single-seat fighter for the Luftwaffe. Focke-Wulf ceased operations in 1964 when it merged with Vereinigte Flugtechnische Werke.
