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 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.

The Bell 412 EPs helicopter is the President's preferred option and as a security measure the Presidential helicopter is always flown by a group of similar helicopters. One helicopter carries the president, while the others serve as decoys. These helicopters are arranged so that the location of the President is obscured after take-off.
In addition to altering the tail, stealth design must bury the engines within the wing or fuselage, or in some cases where stealth is applied to an extant aircraft, install baffles in the air intakes, so that the compressor blades are not visible to radar. A stealthy shape must be devoid of complex bumps or protrusions of any kind, meaning that ...
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 ...
Defensive fighting position; for example, a rifle pit, sangar or fox hole. Demi-lune; Ditch: a dry moat. Dragon's teeth: Triangular obstacles acting as roadblocks for armoured vehicles. Dutch Water Line: a series of water-based defensive measures designed to flood large areas in case of attack. Earthworks
The file starts with a header containing a magic number (as a readable string) and the version of the format, for example %PDF-1.7. The format is a subset of a COS ("Carousel" Object Structure) format. [24] A COS tree file consists primarily of objects, of which there are nine types: [17] Boolean values, representing true or false; Real numbers ...
