### Instruction: Extract what is Top Gun
### Input: The United States Navy Strike Fighter Tactics Instructor program (SFTI program), more popularly known as Top Gun (stylized as TOPGUN), is an American military program that teaches fighter and strike tactics and techniques to selected naval aviators and naval flight officers, who return to their operating units as surrogate instructors.
### Response: The United States Navy Fighter Weapons School was established on 3 March 1969, at Naval Air Station Miramar, California. 

The unit's purpose was to train fighter air crews  in all aspects of fighter weapons systems and the art of aerial combat.  It serves to build a nucleus of eminently knowledgeable fighter crews to construct, guide, and enhance weapons training cycles and subsequent aircrew performance. This select group acts as the F-4 community’s most operationally orientated weapons specialists. Top Gun's efforts are dedicated to the Navy’s professional fighter crews, past, present and future.
