Wishlist (By the Numbers)

[Letalis]

We get into what aircraft would be more fun (for obvious reasons), but there's never really a tie-breaker.  There are plenty of fun aircraft that were significant as well.  I compiled a list of the most numerous aircraft that saw action in WWII which are not included in AH via a brief perusal of wikipedia.  Each aircraft in the top 10 had at least 3k examples built during WWII.  What became obvious is that the Russian side of the Eastern Front, home to half the effort in the ETO and the location of the largest battles in history, is rather under-represented represented by 2 aircraft in 4 variants.  The other thing that became evident is the relatively paltry output of Japanese industry, with the A6M and Ki-43 (both already in game) being the only models to register on the scale.  

Bottom Line:  A very good case could be made that any one of the following aircraft is much more deserving of inclusion than say the F4U-1C or the P-47M (130 examples).  

The results are as follows:

#1
Piper Cub (L-4 variant shown) Eat your heart out Storch!

PO-2 (Eat your heart out some more Storch!)

Tu SB
Actually an interesting aircraft, arguably the most important Soviet bomber of the war..."By June 1941, 94% of bombers in the Red Army air force (VVS RKKA) were SBs."

Yeah, Japanese industry was not really up to the task.  Then you look at Italy's and the fact that they were trying to play with the big boys is just silly.  Japan is at least, by my measure, the weakest of the actual big boys.  There is just such a step down after Japan that it really does put the USA, USSR, UK, Germany and Japan in a separate field than everybody else.

Give the English Wikipedia page for the IAR80 a quick look. You may be amused by what could only have been some Romanian nationalist's attempts to glorify it and the Romanian war materiel industry. I thought it amusing in the same vein as your post.

I don't think it was so much that Japanese industry wasn't up to the task.  I think the major problem was that the Imperial Japanese government (i.e. Tojo and gang) didn't expect the war to last longer than 6 months and didn't make any plans in the event they were wrong.  Even when it was clear that they were in for a long war, Japanese high command still didn't take any measures until it was far too late and too little.

   Well presented list.

+10000 for early russian toys!

Mig 3..............fastest fighter in the world when they were sent to combat but a quirky plane.

The russian pilots who previously flew I185s and I16s mostly mishandled it but a few adapted, flew to the aircraft's strengths, and scored many kills.

One was this guy who, even when equipped with later yaks, would go to great lengths to fly the mig again including finding and fixing up damaged migs he found parked and only the LA7 could convince him to forget about the mig3.

It's obvious from the link above that he figured out and successfully used "boom and zoom" back in 1941.

Many japanese pilots complained about the J2M and KI44 not turning well but they had transitioned from KI27 and A6M5 and were basing thier comparisons to the planes they had flown previously much like the russian pilots who came from I185 biplanes and I16s.

This doesn't mean that the Mig3, J2M, and KI44 could not turn.

It carried a bunch of different armament options with bombs, rockets, sometimes 5 guns with two in gondolas and sometimes the goldola guns put into the wings.

I have no idea of the numbers of each armament optioned planes but, if properly modeled with all of it's good and bad traits, it could end up being quite interesting to fly in aces high for the people inclined to explore it's flight envelope on how to minimize it's bad traits and exploit it's advantages.

Looks like about 3100 examples were built (about the same as the P-63), pretty important type for sure.  Love the looks, appear to be the love child of a Ki-61 and an X-Wing - hopefully with better flight characteristics than the latter...  http://www.youtube.com/watch?v=9jXwA8eP5u0  (skip to 5:00)
