The F-107, nicknamed
Ultra Sabre, is the final evolution of the military track of Sabre aircraft from North American. Generally regarded positively, it lost the contract to the F-105 either through the fate of politics, or perhaps by being the ‘right plane at the wrong time’. Either way, most signs pointed to it being a better-handling plane, lacking only in bomb-armament. The F-107’s performance was indeed superior, due to the fact that it stemmed from an evolution of design alterations instead of being an entirely new plane altogether, as the Thunderchief was. It should be noted that project pilot Bob Baker thought this was a fine-handling aircraft.
The use of antiquated conventional 500lb bombs in Vietnam is likely what caused the F-107 to lose out, because it was not intended to be retrofitted with conventional payloads, unlike the Thunderchief, which had provisions for wing-mounted bomb triplets. Both aircraft were designed, primarily, to deliver a
Nuke Can bomb, the F-107 using a ‘lobbing’ technique, by dropping the bomb in the midst of an intense high speed pull-up. Despite the Top-mounted intake appearing to be aft of a low-pressure zone which could have caused air starvation to the engine, this did not happen due to how forward it was in relation to the fuselage-disturbed air.
The “Ultra Sabre” was the first to employ a Variable Area Intake Duct (VAID), which regulated the volume of air entering the engine, a Pratt and Whitney J75-P-9, for more efficient and powerful combustion. The VAID system saw further use on the A-5, XB-70, and the design of the F-108. As previously mentioned, the F-107 proved very capable in flight, being able to perform rolls in supersonic flight, as well as reach Mach 2+.
For a prototype aircraft, the F-107 was remarkably well-polished. Airbrakes are not replicated on this model, flaps do the job just fine.
