This is a F-84 Thunderjet on a static display at the Wyoming Air National Guard's main gate at the Cheyenne Regional Airport in Cheyenne, Wyoming.
The Republic Thunderjet was a very early USAF jet fighter, first entering service in a straight wing version and then being modified to be a swept wing version, like the one on display here.
Plagued with various problems throughout its service life, the F-84 none the less was a very significant US combat aircraft during the 1950s and saw heavy use during the Korean War. It later saw widespread use around the world and completed its service in Angola in 1974. As can be seen from this example, it saw use by Air National Guard units as well as the regular United States Air Force.
