Book: Kawasaki Ki-45 "Toryu"

A book about this classic aircraft.

 
In WT the Ki-45ko is no doubt the best for air combat, but it has the horrible weakness of nothing in front of the pilot (no armour plate, no armour glass, no engine - nothing!) makes it a poor choice against everything able to return fire.

The Ki-45 tei version in WT is a strange, yet important plane. It has two 250 kg bombs and quick reload for those. This is very useful for the Japanese, since they lack proper light bombers. Ki-49 and G4M attract immediately lethal attention, whereas Ki-45 is a quite quick plane (I was once chased in my P-38 by a Ki-45 and it did not fall back!). Its 37 mm gun creates quite a marksmanship challenge and its 20 mm Schräge Musik weapon is almost never useful. The few successes with the 20 mm against unsuspecting bombers are hilarious, though.

The other Ki-45 versions are not worthwhile in WT unless you insist on upgrading all planes to the maximum due to some kind of collector's zeal.
