Hello everybody. I’d like to introduce and suggest the Bell P-39K-1 Airacobra for the US aviation tech tree, and this is one of my series of suggestions for the mid-series of P-39 variants in the US Army Air Corps and US Army Air Force services. This P-39K-1 started with a new development of Model 26A and was the earliest variant equipped with M8 Bazooka launchers.
History
The P-39K-1 was the first batch of Airacobra aircraft in development of the initial P-39G, but this P-39G designation was dropped and divided into the batches of the P-39Ks, P-39Ls, and P-39Ms. These variants were commonly known as mid-series Airacobras.
The P-39K-1 started with a new company designation of Model 26A powered by the 1,325 hp Allison V-1710-63 and reverted to six exhaust stacks. It differed from the P-39D-2 with new Aeroproducts propellers and additional small vents on each side of the P-39K-1’s nose. The armament remained the same as the P-39D, and the powerplant was identical to the P-39D-2. The additional vents were added to the forward fuselage of the P-39K to improve the ventilation in the cockpit after firing the 37-mm cannon. Consequently, the P-39K weighed 800 pounds more by these minor changes.
210 P-39K-1s were ordered on August 25, 1941. 40 of 210 were delivered to the Soviet Union under the Lend-Lease program.
The P-39K-1s arrived in New Guinea and were issued to the 41st Fighter Squadron of the 35th Fighter Group as the attrition replacements starting in late fall of 1942 to early December 1942, where they would perform aerial combat missions in 1943.

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-39K-1 could be a great choice to add as the premium aircraft since it had limited service in the US Army Air Forces. It could equip M8 rocket launchers at the earliest. Performance-wise, the P-39K-1 is similar to the P-39D-2. The P-39K-1 would make a welcoming addition to the P-39 Airacobra family for US aviation, providing an opportunity for dedicated completionists.
