Jervis — British Tier VII destroyer.

In the mid-1930s, the British Navy needed destroyers that could rival foreign ships of the same type. The new class received two 120 mm twin-gun dual-purpose mounts at the bow end and one at the stern, two boiler rooms, and one funnel. It was the first time that longitudinal frames for the hull, which made it more rigid, were implemented. HMS Jervis participated in the battles at Cape Matapan, Crete, and Sirte. In 1941, she was damaged by Italian submarine saboteurs. The ship took part in operations in the Apennine peninsula and Yugoslavia, as well as in the famous Normandy landings.

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 an 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 number of torpedoes into the water at once. Her ability to utilize Short-Range Hydro-Acoustic 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 a 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.

Research

The research path on this destroyer is very straightforward. The player should prioritize the (B) Hull upgrade to increase their hit points by over 20%, as well as improving rudder shift time and Anti-Aircraft armament. Then, take the Gun Fire Control System upgrade to improve main battery range, as the only remanding researchable module.

Optimal Configuration

Upgrades

The recommended upgrades for Jervis are as follows:

Slot 1: Main Armaments Modification 1
Slot 2: Engine Room Protection *
Slot 3: Aiming Systems Modification 1
Slot 4: Steering Gears Modification 1

The Hydroacoustic Search Modification 1 special upgrade for Slot 2 provides a 20% (36 second) action time boost to Hydro.

Consumables

Jervis equips the following consumables:

Slot 1: Damage Control Party 
Slot 2: Short-Burst Smoke Generator  - 6 charges
Slot 3: Short-Range Hydro-Acoustic Search  - 3 charges

Camouflage

Type 1, 2, or 5 camouflage can be equipped for credits; Types 1 or 5 are recommended at a minimum to reduce detectability range.

Players who wish to spend doubloons can equip Jervis with Type 17 camouflage that lowers her detection radius, reduces the accuracy of incoming shells, reduces her repair costs, and increases the amount of experience she earns.
