Military strategy

John Richard Boyd (January 23, 1927 – March 9, 1997) was a United States Air Force fighter pilot and Pentagon consultant during the second half of the 20th century. His theories have been highly influential in military, business, and litigation strategies and planning.

As part of the Fighter Mafia, Boyd inspired the Lightweight Fighter program (LWF), which produced the General Dynamics F-16 Fighting Falcon and preceded McDonnell Douglas F/A-18 Hornet. Boyd, together with Thomas Christie, created the Energy–Maneuverability theory of aerial combat, which became the world standard for the design of fighter aircraft. He also developed the decision cycle known as the OODA loop, the process by which an entity reacts to an event.
