During which conflict did the first military jet fighters see action?

The first military jet fighters saw action during the Korean War, which took place between 1950 and 1953. This conflict marked a significant development in aviation history, as it was the first time that jet fighters were used in a large-scale military engagement.

The introduction of jet aircraft changed the dynamics of air combat significantly. Fighters such as the North American F-86 Sabre and the Soviet MiG-15 were key players in the air war over Korea. The F-86 Sabre became famous for its effectiveness against the enemy MiG-15, and their encounters are a notable part of aviation history.

In contrast, while World War II saw advancements in aircraft technology and the use of piston-engine fighters, it was not until the Korean War that jet propulsion systems were fully utilized in combat at such a scale. The Vietnam War and Gulf War involved more advanced jet aircraft, but they were not the first conflicts to see military jets in action.
