Putting their previous experience with Allison engines to good use, the P-39 placed the engine in the center of the aircraft, with the propeller driven by a long shaft through which a 37mm cannon was also mounted, firing through the propeller's spinner. Due to persistent development and production problems, the original turbosupercharger was deleted from production models, instead using a single-stage, single-speed supercharger, as was standard on all other Allison-powered products, with the exception of the P-38.
The P-39 performed poorly at high altitudes compared to newer, late-war designs. Most Allied forces thought the Airacobra effective only for ground attack roles, as demonstrated by a few
