The early models of the F-84 looked rather neat, like a tube or a cigar humidor, with an opening in the nose and another in the tail, as if the jet engine had been supplied and the airplane built around it. It had nothing particularly new but was a summation of what at the time was known about jets and about aeronautical engineering.

At the outbreak of war in Korea, the USAF found itself with three different airplanes. The F-86 was obviously the fighter of the group. The F-84 went through several models and was adapted for the ground attack role. It carried a good deal of ordinance and could be fitted with a nuclear bomb. In addition to the usual six .50 caliber machine guns favored by the USAF at the time, it could carry a number of 5-inch rockets, useful against tanks. The low speed and lack of maneuverability were no handicap in attacking ground targets.
