The Boeing-Sikorsky RAH-66 Comanche was an advanced five-blade armed reconnaissance and attack helicopter designed for the U.S. Army. The RAH-66 program was canceled in 2004 after nearly $7 billion was spent on the program before production started. During the early 1980s the U.S. Army began formulating a requirement for a replacement of its helicopters then in service resulting Light Helicopter Experimental program. In 1991 the Boeing-Sikorsky team was chosen to produce prototypes.
