The RAH-66 Comanche had a stellar flight test program, but it’s somewhat too bad that the US Army chose to cancel the Comanche program in February 2004 for budgetary reasons just as the first service test RAH-66s were undergoing various stages of construction (the Comanche program had entered the $3.1 billion engineering and manufacturing development (EMD) phase in June 2000) because if the Comanche had entered service, it might have helped US Army aviators scout the terrain in Afghanistan for signs of a Taliban comeback and attack Taliban fighters, but also eventually provide air support for Iraqi troops fighting ISIS in the 2010s so that areas of western Iraq controlled by ISIS would be cleansed of ISIS terrorists.
