Hello everybody. I’d like to introduce and suggest the Bell P-39F-1 Airacobra for the US aviation tech tree, and this is one of my series of suggestions for the early P-39 variants in the US Army Air Corps and US Army Air Force services. This P-39F was a direct development of the P-39D based on the Model 15 with minor changes.
History
The P-39F-1 of Bell Model 15B was the next production variant developed after the P-39D of Model 15. While almost identical to the P-39D, the P-39F had a new Aeroproducts constant-speed propeller instead of the original Curtiss-Electric, as the replacement was due to the shortage of Curtiss-Electric propellers. The P-39F had twelve exhaust stacks on each side of the fuselage instead of six on each side of the P-39D. The P-39F in service sometimes swapped its 37-mm cannon for the more favored 20-mm cannon, and the P-39F was the last variant to be seen with a 20-mm cannon. The 37-mm cannon would be installed in all subsequent Airacobra variants.
The US Army Air Corps ordered the 229 P-39F-1s on September 13, 1940. Most P-39Fs were deployed to New Guinea in the southern Pacific around early spring-summer 1942, before the end of 1942, and some were deployed to the Aleutian Islands in the northern Pacific under the 57th Fighter Squadron. They served as frontline fighter reinforcements as the deterrent against Japanese air raids on the allied air bases.
The P-39Fs, including the P-39Ds, were also delivered to Australia’s Royal Australian Air Force in the middle and end of 1942. Attack on Darwin, submarine attack on Sydney Harbor, and further attacks by the Japanese aircraft in the north of mainland Australia prompted the urgent need for additional air defenses around Australia, so Australia ordered a loan of several P-39Fs and P-39Ds as an emergency interim measure by the RAAF until more suitable and capable fighters could be delivered for air defense, such as the P-40 Kittyhawks and Supermarine Spitfires. In November 1943, the RAAF received newer fighters of P-40s and Spitfires, and the P-39s had served their purpose and ended their short career within the RAAF. All surviving aircraft were returned to the US Army Air Force.

Conclusion | Why it should be in the game
I made this suggestion to request more World War II-era vehicles for War Thunder. I feel the P-39F-1 had a historical significance and deserves a place in the game, as it had seen aerial combat in the Pacific theater. Performance-wise, the P-39F-1 is similar to the P-39D, but it can switch between 20-mm and 37-mm cannons as a choice. Thus, the P-39F-1 would make a welcoming addition to the P-39 Airacobra family for US aviation, providing an opportunity for dedicated completionists.
