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 ...
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 ...
Stealth technology, also termed low observable technology (LO technology), is a sub-discipline of military tactics and passive and active electronic countermeasures, [1] which covers a range of methods used to make personnel, aircraft, ships, submarines, missiles, satellites, and ground vehicles less visible (ideally invisible) to radar, infrared, [2] sonar and other detection methods.
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]
DUSTOFF: a now traditional call sign for US Army Air Ambulance helicopter operations engaging in MEDEVAC. Echelon formation: a military formation in which members are arranged diagonally. Encirclement: surrounding enemy forces on all sides, isolating them.
At times, the helicopters can fall back as much as a half-mile if the horses and burros are moving in the right direction. And over-populating, now or in the future, can threaten an entire herd or ...
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.
