Reports are flying thick that the Navy SEALs Team Six used an extremely-modified Sikorsky MH-60M Black Hawk helicopters, having stealth features. The rumours of the stealth chopper are making the rounds, after one of the helicopters crashed in the compound of the hideout of Osama bin Laden and that the remnants indicated to its ‘low-observability’ and its capabilities to go undetected on the radar.

Military analysts have said in the US that the chopper’s noise levels had been reduced with the use of extra blades on tail rotor. Also the material used look similar to that used in stealth fighters. The silver finish makes it harder to detect on radar and by infrared sensors. The angles and flat surfaces of the chopper have indicated on the modifications that have gone into the Black Hawk.

The US has attempted to use stealth helicopters before. In the mid-1990s, the Army developed several prototypes of the Comanche helicopter, a reconnaissance helicopter that was at the time a revolutionary step in stealth technology.
