Pierre Sprey

Pierre Michel Sprey was an American defense analyst. Working with John Boyd and Thomas P. Christie at the Pentagon, he was associated with the self-dubbed 'Fighter Mafia', which advocated the use of energy–maneuverability theory in fighter jet design. Claims exist that Sprey was the designer or involved in the design of several military jets, including the F-16 and A-10. The factuality of these claims and potential extent of his involvement is a subject of controversy.
