The R-4360, outputting 3,000 horsepower, would be used to drive a large-diameter, four-bladed propeller unit at the nose with a modestly-sized spinner at center. The aircraft would incorporate a system to utilize some of the engines exhaust power for additional thrust, adding performance as a result.
Unlike the classic wartime fighters, which relied on machine gun armament as standard, the Model 367 was drawn up with 4 x 20mm autocannons showcased as two guns to a wing. The cannons were to be installed outboard of the wing hinged which allowed for the wing-folding feature. It is assumed a limited bomb-carrying capability would be designed into the Model 367 as was seen in the F6F and F4U types.
Despite its promised excellent mix of performance and firepower, the Model 376 was not furthered beyond the paper proposal. Into 1944, the USN enjoyed considerable success with its existing stock of carrier-based fighter and little to no disruption in production of these two lines was sought. As such, the Model 376 joined other would-be aircraft designs of World War 2 as nothing more than footnotes of aviation history. Boeing also drew up the Model 386 at the same time, utilizing much of the form and function of the Model 376 (including the Wasp Major radial) but this model was to sport a pair of three-bladed propellers arranged for contra-rotation for better performance at higher-altitudes. This design also fell to naught.
Even so, these design studies offer an interesting look into what might have been should the war progressed along very different lines.
The Model 376 was estimated to feature a maximum speed of over 400 miles-per-hour, a service ceiling near 35,000 feet, and range out to 1,000 miles. Structurally, it was to have an overall length measuring 39.4 feet with a wingspan reaching 53 feet. Operating weight would reach around 17,000lb.
