Naval fleet model, damage model, characteristic and weaponry changes

  • First-order ammo racks with around 10-20 shots per cannon have been added for large caliber artillery ships. Rate of fire when using first-order ammo racks have been set to the maximum theoretically possible. The rate of fire when using shells from the ammunition stores has remained the same. So vessels which can use first-order ammo racks can shoot several times (7-10%) faster than its standard fire rate. Fires and detonations of the first-order ammo rack will not be fatal for the ship and can cause damage only on the surrounding modules and cause damage to the crew placed within them.
  • For ships with separated ammunition stores, they have been divided into stores for shells and stores for loading. Fires within the loading stores is not fatal for the ship and can lead to the loss of some or all ammunition in the store and also to damages of the surrounding modules.
  • The mechanics of ammunition supply elevators have been added. A damaged elevator can lead to a reduction of the reload speed to the connected cannon battery of between 8-10%. A destroyed elevator can lead a reduction of the reload speed to the connected cannon battery of 20%. One cannon or turret can be operated by several elevators - in the event of maximum damage or destruction for all elevators of this cannon, the reduction will not exceed 10% and 20% respectively.
  • The effect of smoke funnel damage on the ship's speed loss has been halved.
  • Repair speed of torpedoes placed in torpedo tubes has been increased.

Tactical technical characteristics, physics and damage model

  • All ships — The firing range of AI has been corrected. The information about the arming range and launch radius has been added to the stat card for shells with radio fuse.
  • All torpedoes have now own damage model. You can now destroy the incoming torpedo by the direct shot from the shell or by the closed explosion for example from the depth bomb.

Armour-piercing shell of the Brooklyn now costs 10 SL instead of 20 SL earlier.
  • BR of the following destroyers has been changed:
    • Sumner (DD-692) from 4.3 to 4.7.
    • Somers (DD-381) from 4.3 to 4.7.
    • Tashkent (leader) from 4.3 to 4.7.


  • Possibility to create custom user camouflage for ships has been added.


  • The visibility in the research tree of event vehicles which are available for purchase on the market has been added on the PC version of the game (not available for the consoles).
  • The displayed warning regarding the impossibility of retracting landing gear when using suspended boosters has been fixed.

Game mechanics

  • New game mode “World War” has been launched as OBT. In this game mode players can participate in the reconstruction of famous historical battles. In the first season “Recon under Fire” which will last until the 10th of June you will be able to participate in the “Battle of Vitebsk”, Operation “Nordwind”, “Battle for Caen” and “Second Battle of El Alamein”.
  • The ability to hit ATGMs whilst in flight as well as moving torpedoes, bombs and un-guided aircraft missiles with a direct hit from weaponry, shells as well as with the effects of explosions (shockwave and fragments in the air and water) has been added. Bombs with delayed fuse mode enabled already dropped of surfaces (ground) are also subject to all these factors.
  • The algorithm for anti-aircraft missile guidance has been reworked. Now, when the missile is aimed at a target, the control system will keep the missile on the line of sight itself. The target locking accuracy depends on the angular velocity of the target, the distance to it (course parameter) and the maneuverability of the missile. There is no need to manually pre-aim by moving the line of sight in front of targets that have a low angular velocity.
  • New types of sensors - passive optical systems, have been added. Such types of sensors will not be detected by radar warning system indications and can detect and track targets covertly. These systems have been implemented on the Stormer HVM - ADAD (Air Defence Alerting Devices) and Bradley ADATS (Air Defense Anti-Tank System). Passive detecting systems can only provide direction for the detected target. The measured range to the target it must be taken into account.
  • Possibility of launching the AGM-114B missile in LOAL (Lock-on After Launch) mode has been added. To operate in this mode the player needs to turn on the target pointer and point it towards the target and launch the missile. The initial point on the surface of where the sights are aimed at will be selected as the coordinates for the inertial guidance system of the missile. After the launch, the target designation can be switched off for the duration of the missile's flight and on just before it hits the target.
  • The mechanics of air and ground-based radars have been reworked. The following features have been added:
    • Target tracking errors have been added. For example: surface-to-air missiles of Tunguska have a maximum range of 8 km. In real life at this distance its tracking radar has a tracking error over two times greater than the radius of the  missile proximity fuse and kill radius as well. The only way to increase hit probability is to use the optical sight.
    • “Multipath” effect has been added. Radar signal that is reflected from the target and re-reflected from the surface and  appears to come from underground is indistinguishable from the signal of the target. The effect occurs when a target flies at altitudes less than 100 m (and will increase as flight altitudes decrease) which will lead to errors when measuring elevation angles - the tracking radar is looking below the target. In this case it is also recommended to switch to optical sight tracking.
    • Ground clutter has been added. Early fighter radar stations were not able to detect targets because of strong ground reflections. This effect depends heavily on the altitude of the fighter aircraft and the elevation of the radar beam. At low altitudes, the radar stations were blind. The targets under the fighter were poorly detected, or not detected at all.
    • Respawn costs (Spawn points) for ground vehicles of BR 8.0 and higher have been changed:
    • Helicopters without ATGMs have been reduced by 15-20%.
    • Helicopters with ATGMs have been reduced by 15-20%
    • For aircraft above BR 8.0, spawn costs have been reduced to the same values as aircraft of BRs lower than 8.0.
    • For all aircraft and helicopters, the costs of spawning is now linked to the BR of the vehicle (same as onBRs lower than 8.0).
  • Respawn costs in ground battles RB for the following vehicles have been changed:
    • Flakpanzer I: reduced by 2 times.
    • OTOMATIC: increased by 2 times.
    • M3 Bradley: reduced by 25%.
  • The possibility to choose air respawn point for helicopters has been switched off in ground RB.
  • A vessel’s ability to escape from a shoal in naval battles has been improved.


  • The appearance of clouds for the graphic settings “max” and “movie” has been improved.


  • Preparation works for the transition to the new sound engine (project which already has sound events that have been made and prepared; sound databases which   contains sound resources for the game has been created; support of new api for the new sound engine has been added; resources for all vehicles and weapons have been reworked for the support of the new sound engine).
  • Mechanics of simultaneous support of the old and new sound engines has been created. New sound engine will be switched on shortly after the release of update 1.89 and at different times for different platforms.


  • Gamepad vibration has been improved (for PC and for consoles). Now vibration works on all vehicle control types (was previously only on aircraft) and there are additional vibration settings in the gamepad tab in the game settings (Options → Main parameters → Gamepad settings).


  • Romanian language has been added.
