What was recognized as the world's first production supersonic fighter?

The F-100 Super Sabre is recognized as the world's first production supersonic fighter aircraft. It was developed by North American Aviation and entered service with the United States Air Force in 1954. The F-100 was designed to exceed the speed of sound in level flight and was primarily intended for air-to-ground attack missions, though it also had air-to-air capabilities.

Its design included a powerful turbojet engine and an innovative wing shape that contributed to its ability to achieve supersonic speeds. This marked a significant advancement in fighter aircraft technology, making the F-100 a pivotal aircraft in the evolution of military aviation during the Cold War era.

In contrast, while the other aircraft listed have significant contributions to aviation history, they are either not the first or do not represent the introduction of supersonic capabilities in the same manner as the F-100. Understanding the historical timeline and technological advancements in supersonic flight provides essential context for recognizing the F-100's unique position in the development of fighter aircraft.
