The Boeing–Sikorsky RAH-66 Comanche is an American stealth armed reconnaissance and attack helicopter designed for the United States Army.Following decades of study and development, the RAH-66 program was cancelled in 2004 before mass production began, by which point nearly US$7 billion had been spent on the program.
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 ...
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]
Stealth aircraft are still vulnerable to detection while and immediately after using their weaponry. Since stealth payload (reduced RCS bombs and cruise missiles) is not yet generally available, and ordnance mount points create a significant radar return, stealth aircraft carry all armaments internally. As soon as weapons bay doors are opened ...
The helicopter is compatible with GB25 and GB50 guided bombs. [37] The main air-to-air missile deployed by the Z-10 is the TY-90, [38] [26] a missile specifically designed for use by helicopters in aerial combat. [27] The TY-90 is much heavier than the MANPAD missiles usually carried by helicopters, providing better lethality and range. [51]

Z-20 ground display at Airshow China 2022 Z-20 Helicopter. The Z-20 is based on the 1970s S-70/UH-60 Black Hawk, [3] which China acquired in the 1980s. [4] Pakistan may also have allowed China to examine wreckage from the US special forces Black Hawk abandoned during the assassination of Osama bin Laden on 1 May 2011.
