A black project is a term used for a highly classified military or defense project publicly unacknowledged by government, military personnel, and contractors. Examples of U.S. military aircraft developed as black projects include the F-117 Nighthawk stealth attack aircraft and the B-2 Spirit stealth bomber, both of which were highly classified and denied as existing until ready to be announced to the public. In the United States the formal term is Special access program (SAP). The money that funds these projects is referred to as the black budget.
