Consumables

Damage Control Party (DCP) repairs modules, puts out fires, and stops floods. In addition, for the action time of the consumable the ship is immune to incapacitations, fires, and floods.

Unlike other consumables, DCP typically has unlimited charges. The Fast Damage Control Team variant trades a relatively short cooldown for a limited number of charges.

Battleships can reduce the cooldown time with the Emergency Repair Specialist commander skill and increase the action time and the number of charges with the Emergency Repair Expert commander skill.

The Repair Party consumable repairs damage by restoring a ship's hit points. It is found on all battleships, many cruisers, and a few high-tier destroyers.

The Specialized Repair Teams variant repairs very quickly, at a cost of some duration.

The amount of damage that can be restored by a Repair Party charge is the Heal Rate times the Duration, up to the maximum restorable. The India Delta signal increases the Heal Rate by 20%.

Not all damage can be repaired. Health points (HP) lost to Fire, Flooding, and Ramming damage are completely restorable. The restorable amounts of ship damage due to warheads and the amount of damage to the citadel varies by ship.

Damage to different parts of the ship, e.g. bow, casemate, is restored proportionately.

Once launched, the fighter group orbits the ship and automatically intercepts enemy planes that come within a 3km radius^[1]. By itself it is fairly effective at shooting some down. However, shipboard AA defenses, particularly when bolstered by Defensive AA Fire , and a fighter group can wreak havoc. When not engaged, the fighter group may detect concealed enemy ships that come within its visual range. See the Aircraft article for more information.

Ships with access to catapult-launched aircraft often must choose between equipping either a Catapult Fighter or a Spotting Aircraft.
Ships with a catapult often must choose between equipping either a Catapult Fighter or a Spotting Aircraft. Like the Catapult Fighter, a Spotting Aircraft can spot ships if it happens to fly near them, but its primary mission in spotting the fall of main battery shells and passing corrections back to the ship.

The aerial perspective may take some getting used to:

• More vertical lead on the screen is required due to the angle; to make matters worse, many crosshairs are purely horizontal.
• The auto-tracking feature (if used) tends to drift more than it does for the normal zoom.
• The view covers a smaller area due to the angle, so careless zooming may end up with no ship on the screen.

On the other hand, the aerial perspective can be quite handy when shooting at ships behind islands, or at tracers coming out of smoke.

The Spotting Aircraft consumable is available on many battleships on Tiers IV+ and on some cruisers on Tiers IV+, for example on these ships:

• many US and Japanese battleships Tier IV+ (not the 3rd US tech-tree branch (with HE bombers)).
• many Italian battleships Tier VIII+.
• some German and British battleships Tier V+ (not the 2nd tech-tree branches of both nations).
• some other battleships Tier VI+.
• many Italian cruisers Tier V+.
• Dutch tech-tree cruisers Tier IV–VII.
• Spanish tech-tree cruisers Tier VII–X.
• Pan-American tech-tree cruisers Tier VIII–X.
• British tech tree: light cruisers Tier V–VIII and heavy cruisers Tier VII–IX.
• many US cruisers Tier VIII+.
• German tech-tree cruisers Tier IX+.
• Soviet tech-tree cruisers Tier V–VII.
• some other cruisers Tier V+.

Most Soviet, European, Pan-American and Pan-Asian battleships and most Pan-Asian, French, Commonwealth and European cruisers do NOT have it.

In comparison to the standard Spotting Aircraft consumable, the Rapid Takeoff Spotter consumable features a significantly faster cooldown and an extra charge, at the cost of duration.

The High-Precision Spotter increases both the firing range and the accuracy of the main battery guns.

Please see the Smoke Screens article for how smoke is generated, used, and countered.

The Short-Burst Smoke Generator variant trades a shorter cloud duration for a short cooldown and double the number of charges.

A smoke generator produces smoke 'puffs' at regular intervals that merge to form the smoke cloud or screen. All smoke has the same concealment effects but can vary in other characteristics:

• Radius - the size of a puff. (Puffs overlap.)
• Emission time - the length of time the generator runs, producing new smoke puffs. (also called 'Action time')
• Dispersion time - the length of time each puff lasts before dissipating.

• Radius - the size of a puff. (Puffs overlap.)
• Emission time - the length of time the generator runs, producing new smoke puffs. (also called 'Action time')
• Dispersion time - the length of time each puff lasts before dissipating.

This consumable enhances a ship's engine power and top speed. It is found on all but British destroyers, but it can often be swapped out for Defensive AA Fire  on some late-hull American destroyers and high-tier Russian destroyers. It is also available to French cruisers from tier VI onwards and to French battleships from tier VIII onwards. French ships typically have an enhanced Engine Boost compared to the normal variation.

The Emergency Engine Power variant provides a large boost in speed for a short duration, though with more charges.

When activated, a boost that grants +8% will provide an 8% increase in top speed. This means a ship with 35 knot top speed will reach 37.8 knots. The use of this consumable also grants a significant engine power bonus, enabling the ship to accelerate and decelerate much faster, although the exact amount is not given. It can be used to improve maneuverability when attempting to dodge incoming shells and torpedoes. If captains are rushing to attack/defend an area, this consumable should be used as well.

This consumable reduces the reload time of a ship's main battery for a short period.

Main Battery Reload Booster's effect runs continuously: if it is started or ended while a reload is in progress, the reload bonus is applied for the length of time spent under the consumable's effect. In order to maximize the bonus, captains should fire just before activating the consumable. It is not necessary to time the end of its duration so that it lines up with a reload.

For example, for tier VIII cruiser Charles Martel with 11 seconds reload:

• if Main Battery Reload Booster is activated when the reload timer is 8 seconds, the reload timer immediately halves to 4 seconds.
• if the player fires his guns when the Booster is active, the reload timer resets to 5.5 seconds instead of 11.
• if the consumable deactivates when there is 3 seconds left on the reload timer (because it was halved during the activation of the Booster), the timer doubles to 6 seconds.

1. ↑ ^{1.0 1.1 1.2 1.3 1.4} Shares a slot with another consumable (usually Smoke Generator).

When active, Hydroacoustic Search will detect any ship within the detection range without regard to obstacles such as smoke screens or terrain. It will also detect torpedoes at roughly double to triple the torpedo's nominal detection range. (The torpedo detection bonus stacks with the Vigilance commander skill for battleships.) This makes the consumable useful for hunting destroyers, defeating smoke screens, and evading torpedoes.

The Short-Range Hydroacoustic Search variant trades some detection range, notably of ships, for a much longer action time.

Of note, German ships have a superior version with greater range, while Italian ships have no Hydroacoustic Search at all, except those mentioned in the table.
