Which aircraft is widely considered the world's first operational jet fighter?

The Messerschmitt Me 262 is widely regarded as the world's first operational jet fighter due to its role in combat during World War II. Developed by Germany, the Me 262 first flew in 1941 and became operational in 1944. It was groundbreaking because it introduced jet propulsion to military aviation, allowing for faster speeds and improved performance compared to propeller-driven fighters of the time.

The significance of the Me 262 lies not only in its technology but also in its immediate use in the field, where it was employed by the Luftwaffe against Allied forces. This operational status marks it clearly as the first fighter jet that was actually deployed in combat situations, which distinguishes it from other aircraft mentioned.

While the Lockheed P-80 Shooting Star and the Gloster Meteor were also early jet fighters that contributed to post-war aviation advancements, they were either developed later or introduced to service after the Me 262 had already proven the viability of jet-powered combat aircraft. The North American F-86 Sabre, although a noteworthy jet fighter, came into prominence after the Me 262 and was not among the first operational models. Therefore, the Me 262's pioneering status in combat operations solidifies its legacy as the first operational jet fighter.
