The Comanche was a twin-turbine, two-seat (tandem) armed reconnaissance helicopter. Designed to replace the Army's current Vietnam-vintage scout and light attack helicopter fleet, the Comanche featured an all-composite fuselage, fully integrated digital flight controls, and advanced navigation and weapons systems. It was designed to provide U.S. forces with accurate, timely tactical intelligence. The Comanche program validated a number of aircraft systems and components and built and flew two flight-test prototype aircraft in its Demonstration/Validation/Prototype phase from contract award in 1991 through 2000. However, the Army cancelled the program in February 2004 as a part of a reorganization of Army Aviation.
