The '''{{Specs|name}}''' is a premium rank {{Specs|rank}} British destroyer {{Battle-rating}}. It was introduced in [[Update "New Power"]].
+
The '''{{Specs|name}}''' was a J-class destroyer named after Admiral John Jervis. Jervis was laid down on 26th August 1937 and commissioned on 8th May 1939. Unlike other J-class destroyers, Jervis' role was to serve as a flotilla leader for the J-class destroyers forming the 7th Destroyer Flotilla. She was identical to K-class destroyer leader Kelly and N-class destroyer leader Napier. On the second day after war broke out, September 2nd 1939, Jervis managed to capture a blockade runner and two more until the end of 1939. She continued to serve in Home Waters until 1940 when she was sent to the Mediterranean where she served until late 1943. In 1941, she took part in the Battle of Cape Matapan where she torpedoed and sank Italian heavy cruiser [[Zara]] with three torpedoes that hit her magazines and caused a fatal explosion. After that, a boarding party from Jervis captured the crippled heavy cruiser [[Pola]], took off the wounded and let HMS Nubian torpedo and sink the heavily damaged ship. She also participated in the Battle of Crete and the First Battle of Sirte. On her way back to Alexandria, she was badly damaged by an Italian human torpedo attack and had to undergo a six-week-long repair. During 1942, Jervis took part in the Second Battle of Sirte. She also supported Allied landings on Sicily, Anzio, and other places in the Mediterranean. She was decommissioned in September 1944 after taking part in the Normandy landings, but was recommissioned in May 1945 and served in the Mediterranean again until May 1946 when she was placed in reserve. She was sold for scrap in 1949. Jervis was awarded 13 battle honours for her service, two other ships that also served with Jervis matched that number, namely HMS Orion and HMS Nubian, with a single ship exceeding it: the flagship of the Mediterranean fleet, HMS Warspite, with 15 to her name.

HMS Jervis was introduced in [[Update "New Power"]]. Her armament consists of three twin 120 mm Mk. XII turrets on CPXIX mounts with 12 rounds per minute utilizing first-stage ammunition; once that is depleted, the rate of fire drops to still very impressive 10 rounds per minute. Her anti-aircraft weaponry consists of a single quadruple 40 mm QF Mk.IIc autocannon, four twin 20 mm Oerlikon Mk.V autocannons, and two single 20 mm Oerlikon Mk.II autocannons. She is also armed with quintuple and quadruple Mk. IX torpedo launchers with 533 mm Mk. IX torpedoes with a base range of 10 km, above-average speed of 76 km/h and one of the heaviest payloads of 587.2 kg TNT equivalent. Jervis suffers from the same issue as many other Royal Navy destroyers, namely very vulnerable magazines above the waterline under the forward turrets that could after a single hit lead to catastrophic magazine detonation. Utilizing manoeuvrability and speed to evade enemy shells is advised.

The Jervis' protection is practically nonexistent. She only had 3.2 mm of casemate armour to protect her main guns, and her Oerlikon autocannons mount ironically had thicker (but still bad) gun shield of 12.7 mm in thickness. Simply put, the Jervis will take full damage from any of the large cannon calibres, and even small autocannons can pose a threat to her survival.

To make the matter worse, almost every vital part of the Jervis is exposed to enemy fire to an extent, her engines and transmissions are sitting above the waterline with no fuel tanks to absorb the incoming shot, and thus easy to knock out. Her ready ammo racks is a fatal weak spot, as it is placed just nearby the main turrets. Any HE shells that would detonate around her turrets is most likely to detonate them, causing severe damage to the ship.

The 120 mm guns have a short reload time of 5 seconds (ace crew) and feature four types of ammunition; HE, SAP, HE-TF, and HE-VT. The HE shell is reliable against destroyers and some light cruisers, while the SAP shell is only useful for dealing internal damage at close range due to poor penetration. As the turrets have fast traverse speed and good coverage, the anti-air shells will be useful for engaging enemy planes at range if you wish to.

The Jervis is outfitted with four 40 mm Pom-pom autocannons in a single quadruple turret as a secondary armament. The turret is located at the midship section just behind the funnel. The turret can fully rotate but is unable to fire directly at the front and the rear, thus limiting its usage to the enemy coming from above or the boardsides of the ship. While the placement of the Pom-pom turret restricted its usage, it can be very deadly against any boats or aircrafts within its range.

The Jervis is essentially a glass cannon that is good at delivering damage but bad at taking it. Due to her abysmal protection, rushing into the enemy or trading shots with them is essentially a suicide, as most of your critical modules can be quickly taken out before you can take your enemy down. Instead, play as a support ship and stay behind your allies, your guns and torpedoes are a great asset for taking down destroyers and harassing enemy cruisers, and your anti-air defense will keep any of the inbound aircraft or PT boats at bay. With HMS Jervis, you shouldn't travel in a straight line for too long as the enemy will target you, instead using your good mobility and turret traverse speed to avoid incoming fire and do a quick snapshot at them.

Description

The J-class, HMS Jervis (F00), 1944 was a J-class destroyer named after Admiral John Jervis. Jervis was laid down on 26th August 1937 and commissioned on 8th May 1939. Unlike other J-class destroyers, Jervis' role was to serve as a flotilla leader for the J-class destroyers forming the 7th Destroyer Flotilla. She was identical to K-class destroyer leader Kelly and N-class destroyer leader Napier. On the second day after war broke out, September 2nd 1939, Jervis managed to capture a blockade runner and two more until the end of 1939. She continued to serve in Home Waters until 1940 when she was sent to the Mediterranean where she served until late 1943. In 1941, she took part in the Battle of Cape Matapan where she torpedoed and sank Italian heavy cruiser Zara with three torpedoes that hit her magazines and caused a fatal explosion. After that, a boarding party from Jervis captured the crippled heavy cruiser Pola, took off the wounded and let HMS Nubian torpedo and sink the heavily damaged ship. She also participated in the Battle of Crete and the First Battle of Sirte. On her way back to Alexandria, she was badly damaged by an Italian human torpedo attack and had to undergo a six-week-long repair. During 1942, Jervis took part in the Second Battle of Sirte. She also supported Allied landings on Sicily, Anzio, and other places in the Mediterranean. She was decommissioned in September 1944 after taking part in the Normandy landings, but was recommissioned in May 1945 and served in the Mediterranean again until May 1946 when she was placed in reserve. She was sold for scrap in 1949. Jervis was awarded 13 battle honours for her service, two other ships that also served with Jervis matched that number, namely HMS Orion and HMS Nubian, with a single ship exceeding it: the flagship of the Mediterranean fleet, HMS Warspite, with 15 to her name.

HMS Jervis was introduced in Update "New Power". Her armament consists of three twin 120 mm Mk. XII turrets on CPXIX mounts with 12 rounds per minute utilizing first-stage ammunition; once that is depleted, the rate of fire drops to still very impressive 10 rounds per minute. Her anti-aircraft weaponry consists of a single quadruple 40 mm QF Mk.IIc autocannon, four twin 20 mm Oerlikon Mk.V autocannons, and two single 20 mm Oerlikon Mk.II autocannons. She is also armed with quintuple and quadruple Mk. IX torpedo launchers with 533 mm Mk. IX torpedoes with a base range of 10 km, above-average speed of 76 km/h and one of the heaviest payloads of 587.2 kg TNT equivalent. Jervis suffers from the same issue as many other Royal Navy destroyers, namely very vulnerable magazines above the waterline under the forward turrets that could after a single hit lead to catastrophic magazine detonation. Utilizing manoeuvrability and speed to evade enemy shells is advised.

In real life, HMS Jervis is famous for not suffering any crew loss during her extensive career in World War II, despite occasionally taking serious battle damage. However, the "Lucky J" does not have her immense luck to save her crew from incoming fire in the game.

The Jervis' protection is practically nonexistent. She has only 3.2 mm of casemate armour to protect her main guns, and her Oerlikon autocannon mounts ironically have thicker (but still bad) gun shields of 12.7 mm in thickness. Simply put, the Jervis will take full damage from any of the large cannon calibres, and even small autocannons can pose a threat to her survival.

To make matters worse, almost every vital part of the Jervis is exposed to enemy fire to an extent, her engines, and transmissions are sitting above the waterline with no fuel tanks to absorb incoming shots, and are thus easy to knock out. Her ready ammo racks are fatal weak spots, as they are placed just nearby the main turrets. Any HE shells that would detonate around her turrets will most likely detonate them, causing severe damage to the ship.

Mobility

Speedforward / back
AB85 / 31 km/h
RB69 / 25 km/h

Being a destroyer with relatively low displacement, the Jervis is very fast and manoeuvrable. Due to her very poor protection, using her mobility is a key to survive.

Armament

Primary armament

3 х Turret2 x 4.7 inch/45 Mk.XII cannon, CPXIX mounting
Ammunition400 rounds
Vertical guidance-10° / 40°
Main article: 4.7 inch/45 Mk.XII (120 mm)

The Jervis is equipped with six 120 mm 4.7 inch/45 Mk.XII cannons, mounted in three twin turrets in A-Bs-X setup. These guns have very good traverse speed, and the placement of the turrets allow the B and X turrets to completely turn around, which will come in handy when using it with quick turning to avoid incoming shots.

The 120 mm guns have a short reload time of 5 seconds (ace crew) and feature four types of ammunition; HE, SAP, HE-TF, and HE-VT. The HE shell is reliable against destroyers and some light cruisers, while the SAP shell is only useful for dealing internal damage at close range due to poor penetration. As the turrets have fast traverse speed and good coverage, the anti-air shells will be useful for engaging enemy planes at range if you wish to.

Ammunition8960 rounds

Fire rate200 shots/min
Main article: 2pdr QF Mk.IIc (40 mm)

The Jervis is outfitted with four 40 mm Pom-pom autocannons in a single quadruple turret as a secondary armament. The turret is located at the midship section, just behind the funnel. The turret can fully rotate but is unable to fire directly at the front and the rear, thus limiting its usage to enemies coming from above or the broadsides of the ship. While the placement of the Pom-pom turret restricts its usage, it can be very deadly against any boats or aircraft within its range.

For dedicated anti-air defence, the Jervis features ten 20 mm Oerlikon autocannons, with two pairs of dual-mounted Mk V on the bridge and between torpedo launchers and another pair of single-mounted Mk II at the stern. The placement of the guns provides wide coverage against surface and aerial threats, though it is always recommended to man the guns yourself if the enemy gets too close.

Additional armament

Setup 19 x 533 mm Mk.IX** torpedo
Main article: Mk.IX** (533 mm)

The Jervis is loaded with 9 x 533 mm Mk.IX** torpedoes. These torpedoes have 587.2 kg of TNT explosive as the warhead, which is noticeably more powerful than the variants found on British cruisers, and is enough to tackle all targets the Jervis will face. The torpedoes also have a decent top speed of 76 km/h without modification. As the torpedoes have a maximum range of 10 km which is within the range that the Jervis will usually engage, and the torpedo mode modification only adds 3.7 km of extra range, it is advised to uninstall these modifications to increase the torpedo's effectiveness.

Usage in battles

The Jervis is essentially a glass cannon that is good at delivering damage, but bad at taking it. Due to her abysmal protection, rushing into the enemy or trading shots with them is essentially a suicide, as most of your critical modules can be quickly taken out before you can take your enemy down. Instead, play as a support ship and stay behind your allies, your guns, and torpedoes are a great asset for taking down destroyers and harassing enemy cruisers, and your anti-air defence will keep any of the inbound aircraft or PT boats at bay. With HMS Jervis, you shouldn't travel in a straight line for too long as the enemy will target you, instead using your good mobility and turret traverse speed to avoid incoming fire and do a quick snapshot of them.

Pros and cons

Pros:

  • Fast-firing 120 mm cannons with very good coverage
  • Good turret traverse speed, the B and X turrets are fully traversable

  • Good anti-air armament
  • Powerful torpedoes with decent range

Cons:

  • Extremely poor protection
  • All the internal modules can be easily damaged
  • Very low crew count
  • Turrets are easy to knock out
  • Ready ammo racks is exposed to enemy fire and can be detonated

History

HMS Jervis, J-class Flotilla Leader, was a destroyer of the J class. Commissioned just before the outbreak of war, Jervis saw extensive service in the Mediterranean and Atlantic theatres. She participated in multiple major engagements in the Mediterranean, and later participated in the D-Day landings of 1944. Jervis was retired at the end of the war, and later scrapped. She was highly decorated and received 13 battle honours for her service in the Second World War. Jervis also gained a reputation for being extremely lucky, as she never lost a single crew member during her 5 and a half years of service.[1][2]

Design and Development

HMS Jervis on sea trials, early 1939.

The Jervis, as a member of the J class, was designed as a smaller follow-up to the preceding Tribal-class destroyers. Being smaller, the J class had a stronger balance between guns and torpedo armament, compared to the "gunship-style" Tribal-class destroyers. Jervis, in particular, was fitted with additional command space to accommodate the Flotilla commander. Jervis displaced 2600 tons, and was capable of 36 knots (66 km/h).[1] Her main armament consisted of six 4.7-inch (120 mm) guns in three dual turrets, two mounted at the bow and one at the stern.[1] She also carried numerous anti-aircraft defences as well as eight 533 mm torpedo tubes in two quad-mounts.[1]

Jervis was laid down in mid-1937 and was launched in September 1938. She was completed and commissioned in May 1939, just months before the outbreak of the Second World War.

Service history

Following her completion and commissioning, the Jervis served as the flagship of the 7th Destroyer fleet. She first served as a patrol vessel in the North Sea, hunting for axis blockade runners; however, she collided with a freighter in March 1940 and was dry docked for repairs.[2] Once the repairs were completed, she was assigned to the Mediterranean squadron, where she saw extensive service. She escorted convoys to Malta, participated in shore bombardment missions, and provided screening services to the British Mediterranean fleet.[2]

In 1941, Jervis served in the Battle of Cape Matapan, where she sank the crippled Italian cruiser Zara and boarded Zara's sister ship Pola. She later participated in the battles of Crete and Sirte, where she managed to survive undamaged despite heavy allied losses.[2] Later on, she was immobilized for six weeks by an Italian manned torpedo.[1][2]

In 1944, Jervis was reassigned to the British Atlantic fleet, and provided fire support for the forces landing at Gold Beach for the D-Day landings. She was thereafter decommissioned for a refit, which gave her additional anti-aircraft protection.[2] She returned to the Mediterranean after her recommissioning, and served as a patrol ship as World War II drew to a close. Following the end of the war, she was laid up in reserve and used by the cadets as a training ship. After being used for explosive tests, Jervis was given to the ship-breakers for scrap.[2]

HMS Jervis is known as an extremely lucky ship: despite being active for almost the entirety of the war and having served in 13 major naval engagements, she never lost a single crew member.[1] In fact, she was one of just two J-class ships to survive the war. She received 13 battle honours for her service during the Second World War, making her one of the most highly decorated British warships in modern history.[1][2]
