The XF-84H was modifed from an RF-84F by adding a turboprop engine and converting the production tail to a T-tail. Two aircraft were completed, 51-17059 and 51-17060. The first aircraft was taken to Edwards AFB in December, 1954, with first flight on 21 July, 1955. The second aircraft arrived at Edwards on 14 May, 1956, and was later used by the Navy for evalution during their VTOL program. The original designation was XF-106, later changed to XF-84H. Dubbed "Thundershriek" because of the intollerable sound made by the sonic booms emitted by the propeller.
