Why was the RAH-66 Comanche program cancelled?
On February 23, 2004, the U.S. Army announced their decision to cancel the Comanche helicopter program in view of the need to provide funds to renovate the existing helicopter fleet of aging attack, utility, and reconnaissance aircraft. Also a factor was the growing popularity in the military of using unmanned aerial vehicles (UAVs) for reconnaissance purposes in addition to tests, UAVs had proved their worth in the American War on Terrorism against Afghanistan and Iraq.
