Stealth helicopters are helicopters that incorporate stealth technology to decrease an enemy's detection ability. [1] There are a diverse range of technologies used to achieve this decreased detectability; these have largely involved the reduction of several different signatures typically generated by a rotorcraft, including those of noise ...

As soon as weapons bay doors are opened ...
The presence of supersonic and jet-powered stealth aircraft such as the SR-71 Blackbird indicates that acoustic signature is not always a major driver in aircraft design, as the Blackbird relied more on its very high speed and altitude. One method to reduce helicopter rotor noise is modulated blade spacing. [49]
Iran has an air defense system that would require stealth technology to penetrate. [ 21 ] [ 22 ] In December 2009, South Korea 's JoongAng Daily newspaper reported that the RQ-170 Sentinel had been test-flown in South Korea for the past few months and that it was expected to be permanently deployed in 2010 to replace Lockheed U-2 reconnaissance ...
