Not my design but I will make a comment here.
The info posted above is correct for the P-40Ns entry date into the VVS (11-43) and I certainly don't dispute it. I don't think its a stretch to use the P-40N in a mid (July 1943) setup. The P-40E is the reworked version (from the original AH version) with no WEP capability at all ...and was being phased out by early 1943 with the Soviets. By Kursk the Russians did have the P-40K. So we end up having to use the P-40F and/or the P-40N as a "mid war" Russian P-40 (designers choice). Looking at the P-40Ns #s it does not possess any spectacular performace being both slower in climb and speed to the P-39N/Q Aircobra...and lagging far behind the Bf 109G series and the Fw 190A in this setup.
Would the P-40F have been closer to the P-40K? possibly but I don't see a huge difference.
Constructive feedback and discussion is always welcome.
...Dug up the enty date to the P-40K with the VVS they had them by December 1942 according to "Lend Lease Soviet Fighter Aces of WW2" just for info.
