As much as I'd like to believe the Ki.61 is well-matched against the F4U-1, DoK's aircraft evaluation pages dont' bear this out. The Corsair is 40-50 mph faster consistently and all altitudes, and climb rate with WEP is almost the same, yet the Corsair can also out turn the Tony when it gets its big flaps out. With the F4U's reputation for good roll I'm sure it can out roll the Tony also. The only advantage the Tony has is a harder hitting gun package, while the cannon ammo holds out.
Not sure how different it would be if the Ki.61-1a or 1b were in the game - turn and climb performance would improve but it would lose the armament advantage most likely.
So, it appears 1942 is the only year the US and Japan were fairly well-matched in aircraft - beyond that the American advantages of speed and durability pull further and further ahead.
So a Guadalcanal scenario would most likely pit the Cactus Air Force (Wildcat, Dauntless, Avenger, P-39D) against combined IJN/JAAF forces (A6M2, Val, Kate, Ki.43, G4M Betty). These forces seem pretty evenly matched to me.
Brooke are you saying that PTO scenarios just don't draw as many participants as ETO, MTO, or Eastern Front scenarios? And that's why we dont' run them often?
I'd really like to see a late '42 early '43 New Guinea scenario setting some day too - P-39Ds, P-40Es, P-38Gs and B-25s (or Bostons?) against A6M2/3, Ki.43, Ki.61 and G4M Bettys.
Q: Does anybody know of a resource where I can see all the air campaigns of WWII and the order of battle (aircraft, units) for each campaign? I would spend days pouring over that...
