From the flight of the world’s first practical helicopter in 1939, Sikorsky has maintained their heightened commitment to innovation, excellence and safety. Sikorsky Aircraft is one of the world’s leading helicopter manufacturers, producing such well-known models as the UH-60 Black Hawk and SH-60 Seahawk, as well as experimental types like the Sikorsky S-72 X-Wing – and is considered a vital US defense contractor. Sikorsky has supplied the Presidential helicopter since 1957. Sikorsky’s VH-3 and VH-60 currently perform this role. In 2015, Lockheed Martin purchased Sikorsky from UTC for $9 billion.
