The P-47 was the most numerously built U.S. fighter, half of which were the razorback variants of which the majority were built with or retrofitted with underwing hardpoints for fuel or ordinance. As such there is much merit and would add to FSOs historical events and AvA where D-25s are often erroneously subbed and would restore the P-47 to its roll as a pioneering ground attack role in MW.
There is negligible difference between the D-11 and earlier Ds and Cs and even the Cs and limited number of Bs did not see service soon enough to qualify them for Early War the way the dates in the game are arranged, though having a model in EW would be very attractive.
The introduction of the nearly identical D-25 and D-40 has caused the gap in representation in the earlier models, and the M an over representation of the least relevant segment which was well covered by the N.
As I pointed out, the density of P-47 representation already far exceeds the other extensive lines in AH. If any line of fighters has a claim of a need for more examples it is the Yak1/3/7/9 series. We need a Bf109G-6/AS or Bf109G-14/AS far more than an additional P-47 for real performance reasons, not just cosmetics. A 1941 or early 1942 Fw190 would be a great addition as well. The most common Seafire, the Mk III, is also needed.
A LaGG-3, La-5, N1K1-J, Spitfire Mk XII, Ki-61-Ia, Ki-61-Ib, Mosquito F.Mk II, Mosquito Mk IV, Mosquito Mk 30 and P-38H would also all be better gap filling additions than the P-47D-15 or D-22.
