Download the game

Naval fleet testing moves to OBT. US, German and Soviet ships are available to research and purchase for all players.

The game files data compression algorithm has been changed. It will significantly increase the ressources loading speed, lowering the amount of freezes and game stuttering for affected computers, and improve performances on dual-core systems. As a result of those changes and due to implementation of the fleet to the War Thunder, the update have to be around 19GB.

New locations and missions

  • New naval location “Black Sea port”.
  • Increased detalization of the naval location “Green mountains gulf”.
  • Full rework of roads and bridges on the following aircraft battles locations locations: Khalkhin Gol, Ardennes, Korsun. Now bridges correctly coincide with the roadway. They now have "embankments" and bridges are much better combined with the landscape. The structure of roads and routes of AI ground vehicles has been corrected: crossroads have been added, new route points and new roads and routes needed for the missions have been added.
  • Helicopter missions have been refined in accordance with player feedback: more light vehicles have been added, helicopters respawn points have been placed further away from AI target clusters. The players will have to choose if they want to protect its own ground vehicles or go hunt enemy ones. By analogy with the aircraft “Front Line” missions, destruction of any ground vehicle counts for the victory of the team:
    • heavy vehicles — 100 scores;
    • medium — 40 scores;
    • light — 20 scores.

Location and mission updates

  • Naval missions are now available in custom battles.

  • S.M.79 series 4 - injection modification has been removed.
  • PBY-5 - engine display in x-ray view has been fixed, and number of engine cylinders is now displayed correctly.

Flight Model changes:

  • Ju-288c - tuned according to the data sheet.
  • M.B.175T - tuned according to the data sheet.

Naval fleet model, damage model, characteristic and weaponry changes:

  • Multiple vessels now have  side and bow mounted bomb launchers as modifications. They can be launched by pressing the “R’ key in the direction of the camera view.
  • New armour types have been added. Now naval vessels have bullet-proof, fragmentation-proof, rolled or cast homogeneous armour depending on the vessel.
  • The fragmentation effect has been reworked. Spread and damage have become more realistic. Depending on the ammo weight and shard type, the resulting fragmentation may be different in weight, number and total damage. All shards spread according to diagram for a “damage sector”. Additionally, one round may produce shards that vary in their weight and penetration power.
  • Naval Vessel DMs have been reworked:
    • Artillery, upper structures, torpedo launchers and other deck-based components are now more vulnerable to explosions, shards and direct hits. Any unarmoured upper structures can be damaged so they won’t function even with MG fire.
    • Internal modules may also be damaged by explosions, kinetic damage, shards and fire in different situations. Thus boiler compartments are more vulnerable to direct hits and shard damage, unlike controls that are much more vulnerable to explosions.
    • Engines situated in drowned compartments as well as transmission and ammunition rooms will be damaged or become unavailable until the water is pumped out of that section.
    • Fragmentation-proof blankets or screens whilst whole will prevent shards from penetrating dependant on the blankets thickness and the damage power of the fragments.
    • Survivability and resistance towards different types of damage have been reworked for the sections occupied by the crew; an explosion or dense fragmentation will inflict much greater damage than a single AP round that penetrates through a vessel without internal fragmentation.
    • Larger vessels can survive a hit by a light torpedo (SET-40 for example), however they still suffer severe damage.
  • DM has been reworked for the German SF-40’s:
    • The crew has been moved to the upper deck and artillery deck.
    • Upper deck structure is now protected with 10mm rolled armour that contains most of the crew, however the control cabin remains unprotected.
  • All MGs and autocannons up to 20mm now have stabilization by using of the gunner's shoulder rest.
  • Correct radio cabin dimensions have been added for all vessels. The crew is placed depending on the vessel type and historical data.
  • A new criteria for vessel destruction has been added. When massive damage from an explosion is received (it depends on the vessel size and class) they may still be destroyed even if their total crew value is not lower than required minimum standard to class the ship as previously inoperable.
  • MBK 161 mod.1944 Soviet armoured boat has received its historical camo.
  • The German LS class reserve torpedo boat has been renamed to LS 3.
  • The maximum speed of the German K-2 Kanonenboot has been changed from 30 to 18.6 knots according to historical information.
  • Looping torpedoes around the same area by launching during a sharp turn has been fixed.
  • The appearance of fuel tanks in X-Ray view has been visually improved and is now the same for all ships.


  • Support for a new type of texture compression (incompatible with game version 1.81 and older) has been added).

  • A bug where the camera focused on the rear end of a naval vessel at the start of a battle has been fixed.
  • It  is now possible  to capture points in  Naval battles with hydroplanes/seaplanes.

Changes specific to the PlayStation®4 platform.

  • A new setting for cursor speed in the menu has been added (available when the cursor control by stick is enabled)
