Q: The Molotov apparently is modeled after it’s 1942-1944 state. During this period, four 37mm anti-aircraft guns were installed on the roofs of the second and third turret. But these guns are missing on game ship model. However, Tirpitz has her (turret) roof AA guns.
A: By the way, Tirpitz AA guns are not working. They will be enabled in 0.5.6. Same patch, Molotov and several other ships will receive their AA guns on main battery turrets.
