Detonation in World of Warships is caused by the ignition of at least one of the Magazine modules of the ship. Historically, they are where the powder charges and ammunition for the main artillery are stored. In game, sufficient damage that causes one magazine to explode will surely result in the destruction of the entire ship.
To cause a detonation to occur, damage needs to be dealt to the magazines, which are found underneath the primary turrets and/or primary artillery. In other words ships, like Novik, that have non-enclosed rifles behind blast shields have magazines located beneath the deck. Damage to the magazines can be caused by penetrating damage from direct AP hits or splash damage from HE shells or Torpedoes, if they hit close enough to them.
It should be noted that there is no situation in the game that warrants a 100% Detonation chance. With that said, certain actions or choices will increase the probability of Detonation; a few of them are highlighted below:
- As stated above, taking damage to the magazines will increase the chances of detonation occurring. When a magazine loses all of its hit-points, the chance of detonation will increase to its maximum native value (Note: this is still below 100%). Each ship has its own metric for calculating detonation chance based upon magazine hit-pool.
- Therefore, by this logic, aircraft carriers can never be detonated since they have no magazine.
- Each ship has its own armour-value for the magazines, therefore ships with thinner magazine armour will inherently have a higher detonation chance.
- Mounting either India X-Ray or Juliet Whiskey Unaone signal flags will increase magazine detonation chance by 5% each.
As stated above, the occurrence of a magazine detonation will also detonate the entire ship; resulting in a complete depletion of the total ship’s hit-pool to zero. To further emphasize: even the detonation of one magazine is enough to cause an explosion of the entire ship.
The chance of detonation can be decreased in three ways:
- Mount Magazine Modifications 1 as the Upgrade for Slot 1. This will decrease the chance of magazine detonation by 70%.
- Mount the Juliet Charlie signal flag; this will decrease the chance of magazine detonation by 100%. In other words: the magazine will not detonate if this signal is mounted on the ship.
- Another way to reduce the chance is by angling. This is by pointing the nose of the ship at or close to the ship shooting you. Certain ships you can point the rear of the ship to the enemy and prevent detonations. Since most (about 95%) detonations are caused by showing your sides (aka broadside) to the enemy. By the way angling can also greatly reduce citadels. This is why you will notice when shooting at or aiming at a ship it will turn in or away reducing the angle and ability to detonate and/or citadel.
The Juliet Charlie signal flag is awarded to players whom earned the Detonation award: their magazines had detonated in a match. The award can be obtained once per battle. The signal flags can only be obtained once per day as a bundle of 10.
