Maiden Flight of Sikorsky-Boeing's Defiant Helicopter
Several companies are developing helicopters that could replace the U.S. Army’s aging Black Hawk fleet in the coming decades. One of those futuristic aircrafts, Sikorsky-Boeing’s Defiant, took its first test flight two weeks ago.
The Defiant is based on Sikorsky’s experimental X2 technology, which holds the record for being the fastest helicopter technology in the world. A demonstration craft reached 435 km/h in 2010, beating the 1986 record of 400 km/h by the Fédération Aéronautique Internationale.
