The XF-84H was constructed at Republic's fabled Farmingdale facility before being delivered to Edwards AFB by train. First flight was recorded on July 22nd, 1955.

As the name implies, the Thunderscreech had some serious noise issues. The aircraft's supersonic propeller tips made it extremely loud. In fact the noise was so loud that it damaged neighboring structures and gave ground crew members headaches and nausea.

Republic came up with the XF-84H by taking the wings from an RF-84F Thunderflash and modifying the fuselage to park a 5,850 horsepower Allison XT40-A-1 turboprop engine where the turbojet engine would normally be.
Thunderscreech Republic's XF84H Was a Uniquely Loud Antique
Although the XF-84H was one of the fastest single-engine, propeller-driven aircraft ever built, it never approached supersonic speed. Due to poor performance and high maintenance requirements, the XF-84H never became operational. The XF-84H remains the loudest aircraft ever built. H/T Earl Belz. Photo credit: U.S. Air Force

Noise The XF-84H was almost certainly the loudest aircraft ever built, earning the nickname "Thunderscreech" as well as the "Mighty Ear Banger". On the ground "run ups", the prototypes could reportedly be heard 25 miles (40 km) away.

The XF-84H was created as an attempt to combine the best of both worlds; high speed, and fast acceleration. The engine chosen was the Allison T40 turboprop engine, which was comprised of two T38 turboprop engines mounted side-by-side. The two engines met at a common gearbox that rotated the propeller.

The turbojet-powered XF-84H was a variant of Republic Aviation's F-84 Thunderstreak. An Allison XT40-A-1 turboprop engine, rated at 5,850 hp, served as the power source for this novel aircraft. The XT40 drove a variable-pitch, 3-blade, 12-foot diameter propeller at 3,000 rpm. The propulsion system's thrust level was changed by varying blade.

The XF-84H was a joint Air Force/Navy project created by modifying a jet-powered F-84 Thunderstreak fighter to carry the T-40 turboprop engine system. The two T-38 engines that made up the T-40.

Two XF-84H prototype aircraft were built by Republic Aviation. The use of a T-tail was required to keep the horizontal tail and elevator in clean air flow. In flight, they were destabilised by the powerful torque from the propeller, hindered by problems with the supersonic propeller blades, and plagued by engine-related glitches.

The Republic XF-84H "Thunderscreech" was an experimental turboprop aircraft derived from the F-84F Thunderstreak. Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome aerodynamic deficiencies and engine reliability problems, resulting in the program.
