Engine Boost Data
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.
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.
A ship's engine smoke will visually appear much thicker during the duration of the consumable. However this effect is purely cosmetic. Engine Boost has no impact on a ship's concealment value.
Although British destroyers do not have this consumable, they have excellent initial engine power by default. This means that although their top speed is limited, their acceleration from stop is even faster than other destroyers with Engine Boost active.
*: This does not apply to premium British destroyers. They have normal initial engine power and Engine Boost consumable, similar to destroyers of other nations.
