In addition to providing an excuse for the 4450th's existence and activities the A-7's were also used to maintain pilot currency, particularly in the early stages when very few production F-117As were available. The pilots learned to fly chase on F-117A test and training flights, perform practice covert deployments, and practice any other purpose that could not be accomplished using F-117As, given the tight restrictions imposed on all F-117A operations. On off-range flights, the pilots talked to the air traffic controllers as if they were in an A-7D Corsair II. Each F-117 aircraft also carried a transponder that indicated to radar operators that it was an A-7.[1]
