The XF-84H was derived from the RF-84F as a supersonic propeller test vehicle driven by an afterburning Allison XT-40 turboprop engine. Two aircraft were built and briefly tested as noise produced by the propeller even at idle was too severe for safe ground crew activities. The sickening noise gave the aircraft its nickname "Thunderscreech." It was the first US aircraft built with a Ram Air Turbine (RAT) which provided emergency electrical and hydraulic power in subsequent US aircraft, but provided needed power for the XF-84H when landing. Another novel feature was a "take-off fin" or "vortex gate" aft of the cockpit to overcome the effects of the propeller torque. The flight program lasted from June 1955 until October 1956 with the program being taken over by the McDonnell XF-88B which flew until January 1958. The XF-88B had both turbojet and turboprop engines and could taxi and take off without the turboprop operating, thus without subjecting the ground crew to the painful noise.

This monograph opened more questions and then left me wanting for more. For example it states the switch over to the single propeller shaft was done before the aircraft were built. The picture of the prop tach shows a needle marked "1". This is typical of a dual tach set-up. Why have that when you're only driving a single shaft propeller? Other questions arise such as why did the RH wing have an additional fuel cell with an extra 10 gallons compared the the LH wing? Another missing tidbit was why BuAer insisted on an afterburner.
The book follows the usual Legends format with a little pre-history, design, usage then the available models. As usual with the series there is an abundance of detail photographs. A nice surprise was a one page description of the XF-88B. Highly recommended for anyone with an interest in early jet fighters or USAF experimental programs, ( )
