Jervis — British Tier VII destroyer.
The J-class ships became the pioneers of the the new generation of British destroyers. Their increased size enabled them to carry powerful artillery in new twin mounts.

Player Opinion
Performance
Players will find Jervis a pleasant upgrade from Icarus, being an upgrade across the board. As a warship, she prefers to find herself on the front lines, taking advantage of her powerful gun battery and stealth. This also helps players use her torpedo battery to its fullest, compensating for the relative inferiority in quality compared to many of her contemporaries.
Perhaps one of Jervis’ best assets is the power of her gunnery at medium to close range, especially when she's aggressively charging enemy ships. It is trivially easy for the player to bring all six guns to bear, even when rapidly switching from side to side, and combined with her high rate of fire, this allows her to quickly pummel enemy destroyers, gaining and early advantage in a fight even against enemy destroyers able to bring to bear their full armament. Her massive quantity of torpedoes also allows her to put a staggering amount of torpedoes into the water at once. Her ability to utilize Hydroacoustic Search allows her to be safer when charging enemy smokescreens (or utilizing her own) with the earlier detection of torpedoes — although her Hydro is inferior to those of German destroyers, so it should not be relied upon to spot enemy ships.
For all her benefits at mid to close-range combat, players will find that Jervis’ abilities drop off sharply at longer ranges - in fact, about 7 kilometers is where this happens. Not only is this the maximum range of her torpedoes, but it's also the edge of her effective maximum gunnery range due to the ballistics of her guns. The ballistics of this guns are actually inferior to that of the 5"/38 found on most American destroyers, which means only the slowest targets are viable choices at longer ranges. This puts a hard cap on the engagement range of Jervis, and the player should generally seek to avoid exposing themselves in such engagements - the better ballistics of weapons such as the Soviet 130mm, or the 152mm guns found on light cruisers, will give them a major advantage over the player at ranges over 7 kilometers.
The smoke of Jervis bears unique attributes that will effect how she plays. Due to its rapid reload time, it can be used frequently, but players should be aware of its short generation time and the short period of time that is lasts for. Because of this, it is extremely inadvisable to use in order to sit and HE-spam enemy targets. Instead, it is advised players use it as a supplement to their concealment, using it to break contact with enemy ships more rapidly, creating a barrier that will last just long enough for you to put adequate distance between the player and the enemy.
Like most destroyers, Jervis is a warship who's lethality increases as the battle wears on. The fewer ships that can challenge its concealment and close-range lethality, the easier it will be for the player to close in on and ambush enemy ships. Destroyers the player can get close to will melt under Jervis’ gunnery, and larger ships will find it difficult to avoid her spreads of ten torpedoes, especially when they can be single-launched for precision accuracy.Pros:
- Good guns - fast firing with decent range.
- Large number of torpedoes.
- Excellent firing arcs forward - the aft turret can fire 26 degrees off the bow, and rotates 360 degrees.
- Great concealment.
- Decent maneuverability - decent top speed, great turning radius and decent rudder shift.
- Smoke consumable has a rapid reload, and Jervis also carries the Hydroacoustic Search consumable.
Cons:
- Torpedoes individually aren't very good.
- Smoke duration is short in all respects.
- Her anti-aircraft armament is negligible (typical for a destroyer).
- Her main battery shells are slow in flight and lack penetration.
- Like all RN DDs (save for the Premiums Gallant and Cossack), she lacks the Engine Boost consumable.

Optimal Configuration
Upgrades
The recommended upgrades for Jervis are as follows:
- Slot 1: Main Armaments Modification 1
- Slot 2: Propulsion Modification 1
- Slot 3: Aiming Systems Modification 1
- Slot 4: Steering Gears Modification 2
Main Armaments Modification 1 is recommended for Slot 1, although is advisable to take Magazine Modification 1 may also be used if players have no Juliet Charlie () signal flags to spare. Propulsion Modification 1 is the best option for Slot 2. but if players have access to the Hydroacoustic Search Modification 1 module, they may wish to use that instead in order to maximize the power of their hydro.
Commander Skills
Key skills for Jervis commanders can vary drastically depending on how they choose to set up their ship, in particular among the third tier of skills. The first tiers are almost invariably "Priority Target" and "Last Stand". However, on the third tier many options are viable - "Torpedo Armament Expertise" to increase your already considerable volume of torpedoes, "Basic Firing Training" to further increase your excellent rate of fire, "Superintendent" for extra charges of Smoke or Hydro, or "Demolition Expert" to increase fire chance (especially if the player chooses to take IFHE). Even "Vigilance" is useful, to increase detection via the Hydro. At the fourth tier, "Concealment Expert" should absolutely be the player's priority.

Consumables
Jervis can equip the following consumables:
- Slot 1: Damage Control Party
- Slot 2: Smoke Generator
- Slot 3: Hydroacoustic Search
Camouflage
Type 1, 2, or 5 camouflage can be equipped for credits; Types 1 or 5 are recommended at a minimum to reduce detectibility range.
Players who wish to spend doubloons can equip Jervis with Type XX camouflage that lowers her detection radius, reduces the accuracy of incoming shells, reduces her repair costs, and increases the amount of experience she earns.
