In April 2009, the Department of Defense decided to terminate production of the F-22A Raptor. In advance of the decision, the Air Force asked RAND Project AIR FORCE to identify the costs and the industrial base implications of various shutdown options. This monograph evaluates the implications of three shutdown options for the F-22A industrial capability: shutdown; shutdown and restart; and warm production, in which a small number of aircraft are produced until a decision is made to return to full-rate production.
