The Sikorsky S-69, also known as the XH-59, was an experimental high-speed helicopter developed by Sikorsky Aircraft in the 1970s. It featured a coaxial rotor system combined with turbojet engines to achieve higher speeds than conventional helicopters. While the programme did not lead to a production aircraft, it provided valuable insights for future high-speed helicopter designs, influencing later developments like the Sikorsky X2 and Raider series.
