In the previous War Thunder update, we introduced T-80B, a top main battle tank of the USSR/Russian tech tree. In update 1.83 Masters of the Sea, we will introduce a new researchable module for this vehicle – the Kontakt-1 add-on explosive reactive armor. It will significantly boost the tank’s defense against HEAT projectiles, such as chemical rounds and anti-tank guided missiles. In combination with the main passive armour of the vehicle, this will provide increased anti-HEAT protection of up to 850-900 mm, helping it to withstand fire from even the most powerful ATGMs.
