Stealth helicopter


Stealth helicopters are helicopters that incorporate stealth technology to avoid detection. Helicopters are in many ways less suitable for stealth technology than airplanes are, because of the noise generated by their rotor blades, which also give off a strong radar signature. In recent years, designs for blades have emerged that can significantly reduce noise, which is a major issue for clandestine use of helicopters. A raid on the compound of Osama bin Laden in May 2011 utilized what appeared to be two Sikorsky UH-60 Black Hawks, heavily modified for quieter operations and employing stealth technology to be less visible to radar.
