Wallpaper Description:
The Boeing-Sikorsky RAH-66 Comanche was an advanced five-blade armed reconnaissance and attack helicopter designed for the United States Army.

The RAH-66 program was cancelled in 2004, before mass production began, after nearly US$7 billion was spent on the program.

During the early 1980s, the U.S. Army began formulating a requirement for the replacement of its helicopters then in service, resulting in the Light Helicopter Experimental program.

In 1991, the Boeing-Sikorsky team was chosen to produce prototypes.

The Comanche would incorporate stealth technologies, featuring a number of designs previously untried.

It was to employ advanced sensors in its reconnaissance role, and was intended to designate targets for the AH-64 Apache.

The aircraft was also armed with missiles and rockets to destroy armoured vehicles.

Two RAH-66 prototypes were built and conducted flight testing from 1996 to 2004. Since the cancellation the prototypes have been placed on display.
