A large number of variants of the General Dynamics F-16 Fighting Falcon have been produced by General Dynamics, Lockheed Martin, and various licensed manufacturers.

The United States Air Force, four of its NATO partners, and the Pakistan Air Force, a major non-NATO US ally, are the primary operators of General Dynamics F-16 Fighting Falcon.

The General Dynamics F-16 Fighting Falcon (in later years manufactured and marketed as Lockheed Martin F-16) has served the United States and the air arms of 25 other nations.
