This is a new DDB-C game against a different opponent. It's historical start with the usual house rules (nothing too restrictive). I plan to try a different approach to aircraft production. If I can last long enough for it to pay off!
The D4Y3 Judy will be the first replacement for the D3A1 Val. Scheduled for delivery in Aug '44, six R&D sites will accelerate that as much as possible. The Aichi Ha-60 engine is therefore not needed but will be researched so that a few can be produced, then switched to something else, like the Mitsubishi Ha-32 and Ha-33 to get the engine bonus.
The B6N2 Jill will be the first replacement for the B5N2 Kate. Scheduled for delivery in Nov '44, six R&D sites will accelerate it as much as possible. B5N1 Kates will be built from Dec 8 to use up the 99 Nakajima Hikari engines in inventory, as well as the B5N2 Kate.
Seven sites will research the A6M2-N Rufe and six of them will convert to the A6M5 Zero (and A6M5 c Zero) while only one produces the Rufe.
Seven sites will research the A7M2 Sam and six sites will research the Ki-83 Army fighter, both due in '45.
Five sites will research the Ki-44-II a Tojo for delivery in mid-'42. Four sites will research the armored Ki-43-II a Oscar (maybe a poor choice), but they can be used in China to replace the Nates.
Six sites will research the Ki-84 a Frank and N1K1-J George. With the engine bonus I anticipate the George becoming available the first quarter of '43. Two sites will research the P1Y1 Frances, the B7A2 Grace, and the Ki-67-I a(T) Peggy.
