War Thunder Update 2.57.1.103 Fixes Server Desync Behind Radar and Missile Failures
The "Mark of distinction for sailors 4" task and active Premium Accounts have both been extended by 24 hours.
War Thunder Update 2.57.1.103 targets a critical server-and-client desynchronization bug that could make several combat systems fail. Gaijin Entertainment published the changelog in its Steam announcement on August 20, 2026.
The issue affected more than one type of vehicle or weapon system. Ground vehicles and ships could not be repaired, collision calculations could allow vehicles to pass through one another, and aircraft could lose missile guidance, radar target locks, or the ability to open bomb bays. Ship hit registration and target following in modes with enemy markers were also affected.
The update also extends the “Mark of distinction for sailors 4” in the Guardian of the Baltic Sea event by 24 hours. Active Premium Accounts receive the same 24-hour extension. In Nuclear Escalation, a separate bug that prevented players from spawning with the B-52H has been fixed.
