Why missile confidence displaced dogfight training after Korea

Did the United States abandon dogfight training because of its Korean War experience?

No. It expected missiles to end close air combat after Korea, but Vietnam disproved that assumption and helped bring specialist dogfight training back.

The doctrinal break came after the Korean War rather than during it. American planners expected air-to-air missiles and changing interception methods to prevent fighters from reaching close combat. Vietnam exposed the gap between that expectation and operational reality. The Navy's Top Gun school restored specialist training after combat showed that technology had not removed the need for dogfighting skill.
