Historically, the B29 could carry 184 AN/M47 napalm canisters. It not being able to ingame is completely ahistorical and I thought the game was meant to be historically accurate for the vehicles.
Isn’t Napalm kinda OP against bases, if so it’s probably a balancing decision. Also War Thunder does many things for balancing sake or can’t because of the limits of Dagor, like how the BMPT doesn’t have APFSDS or the Merkavas having the LAHAT
tu4 china gets 40 and I see no complaints
40≠184
