Aircraft classified as first generation jet fighters are the first attempts at creation of military aircraft using jet engines. A few were developed during the closing days of World War II and saw very limited combat operations. The generation can be split into two broad groups, slower jets with straight wings common to World War II era fighters such as the Me 262 and the Meteor, and mature swept-wing first-generation fighters such as the F-86 used in the Korean War which are controllable at near sonic, and controllable in a dive at supersonic speeds.
