The F-18 HARV (High Alpha Research Vehicle) was a modified McDonnell Douglas F/A-18 Hornet used by NASA in a 3-phase program investigating controlled flight at high angles of attack using thrust vectoring, modifications to the flight controls, and with actuated forebody strakes. The program lasted from April 1987 to September 1996.

NASA reported that in one phase of the project, Armstrong Flight Research Center "research pilots Bill Dana and Ed Schneider completed the envelope expansion flights in February 1992. Demonstrated capabilities included stable flight at approximately 70 degrees angle of attack (previous maximum was 55 degrees) and rolling at high rates at 65 degrees angle of attack. Controlled rolling would have been nearly impossible above 35 degrees without vectoring." Performance figures were not listed for other phases.
