History Highlight

In February 1953, the Utah Air National Guard’s 191st Fighter Squadron, then equipped with the F-51D Mustang, was redesignated the 191st Fighter-Bomber Squadron after receiving eight F-51H Mustangs.

The F-51H was essentially a completely new aircraft from its Mustang counterparts. It was considerably lighter than the F-51D and as a result, could reach a top speed of up to 487 mph, 50 mph faster than the F-51D. The F-51H was armed with six .50 caliber machine guns and could carry two 1,000-pound bombs or an array or rockets.

Utah Air National Guard “Ace”, then Maj. Clifford Jolley said, “it was really a totally different airplane. There were no interchangeable parts. They were a lot lighter built and wouldn’t take near the abuse that the 51D would, but they were a nice flying airplane. The gunsights worked terrible. I know, I spent weeks up at Hill Field bore sighting and firing the guns for our first summer camp. It was a nightmare because the gunsights would go out so quickly, and all of a sudden, we didn’t know where we were shooting! We tried the gum on the windshield routine and all those things, and it just didn’t work.”

In 1948, the Air Force changed the designation of the P-51, with “P” for “pursuit” to “F” for “Fighter”. The Utah Air National Guard flew F-51Hs from 1953 to 1955 when it was replaced by the F-86A Sabre.
