Description

GarageImage Isles class (T-285).jpg


The Isles class, HMT Liscomb (T-285) is a rank II British sub-chaser with a battle rating of 1.7 (AB/RB/SB). It was introduced in Update 1.83 "Masters of the Sea" as part of the British fleet Closed Beta Test.

General info

Survivability and armour

Isles class (T-285) internals (starboard side). Note the large ammo racks below the forward gun and in the bow.

Isles class (T-285) has the following armour layout:

Any gun in the game is able to penetrate anywhere on the boat, including the gunshields, at practically any range.

There is currently no gun in the game that can hull-break Isles class (T-285).

Isles class (T-285)'s hull is split into four compartments. The first compartment starts at the bow and ends where the raised forecastle ends, just in front of the forward 4 in QF Mark V cannon. The second starts the end of the forecastle and ends in front of the bridge. The third starts at the bridge and ends in front of the aft 20 mm/70 Oerlikon Mk.II mount. The fourth starts at the aft gun mount and ends at the stern. Isles class (T-285) is notable for being one of the only rank I boats to have the "Shrapnel Protection" modification, though this doesn't affect survivability much. With a crew complement of 40, overall survivability is high.

Isles class (T-285) has two types of ammo racks: one ammunition storage and one shells room. The ammunition storage is located below the forward 4 in QF Mark V cannon; it is never emptied. The shells room is split into two locations (though damaging one will also damage the other): one below the ammunition storage and one in the bow, both above the waterline; it is emptied when there is only one round of ammunition remaining for the forward 4 in QF Mark V cannon. Destroying either the ammunition storage or the shells room does not destroy the boat.

Armament

Primary armament

For her primary armament, Isles class (T-285) has one 4 in QF Mark V cannon in a single mount forward. It has 150 rounds of ammunition available for it. Stock, the mount can traverse horizontally at a rate of 10°/s and vertically at a rate of 6.8°/s; with the "Primary Armament Targeting" modification installed, it can traverse horizontally at a rate of 12°/s and vertically at a rate of 8°/s. The gun is single-shot and has a nominal rate of fire of 12 rounds/min. With a stock crew, it can be reloaded in 6.5 seconds; with an aced crew, it can be reloaded in 5 seconds.

Secondary armament

For her secondary armament, Isles class (T-285) has three 20 mm/70 Oerlikon Mk.II cannons in three single mounts, one aft and two on either side in front of the bridge. For each mount, there are 1,200 rounds of ammunition available for a total of 3,600 rounds. Stock, each mount can traverse horizontally at a rate of 64°/s and vertically at a rate of 64°/s; with the "Auxiliary Armament Targeting" modification installed, they can traverse horizontally at a rate of 75°/s and vertically at a rate of 75°/s. Each gun has a belt capacity of 60 rounds and a rate of fire of 450 rounds/min. With a stock crew, they can be reloaded in 2.9 seconds; with an aced crew, they can be reloaded in 2 seconds. Their maximum range against surface targets is roughly 2.1 km.

There are three choices of ammunition available:

Anti-aircraft armament

Main article: Lewis 1916 (7.72 mm)

For her anti-aircraft armament, Isles class (T-285) has four 7.72 mm Lewis 1916 machineguns in two twin mounts, one on either side of the bridge. For each mount, there are 3,880 rounds of ammunition available, 1,940 rounds per gun, for a total of 7,760 rounds. There are no stated horizontal or vertical traverse rates given in-game, though the mounts handle very similarly to, if not exactly the same as, other twin and quadruple 7.72 mm Lewis 1916 machinegun mounts which, when stock, can all traverse horizontally at a rate of 64°/s and vertically at a rate of 64°/s; with the "Anti-Air Armament Targeting" modification installed, traverse horizontally at a rate of 75°/s and vertically at a rate of 75°/s. Each gun has a magazine capacity of 97 rounds and has a rate of fire of 550 rounds/min. With a stock crew, the guns can be reloaded in 10.4 seconds; with an aced crew, they can be reloaded in 8 seconds. Their maximum range against surface targets is roughly 1.6 km.

No ammunition choices are available for this gun. Although not directly stated in-game, the guns fire one tracer round every other round, so they most likely use the standard Default ammunition choice of the 7.72 mm Lewis 1916 machinegun which has the following composition and penetration statistics:

  • Default: AP/T/AP/T

Special armament

Main article: Mk.VII depth charge

Isles class (T-285) can carry up to 20 Mk.VII depth charges. These are split into two chutes on the stern carrying 10 depth charges each. They drop one at a time in this order: alternating port and starboard starting on the port side.

Before spawning, the detonation time delay for both types of depth charges can be set anywhere between 3 seconds and 10 seconds.

196 TNT 130 130

Usage in battles

Despite being classified as a sub-chaser, the T-285 acts more like a heavy gun platform with its varied and effective weaponry on a slow-moving ship. Because of its large size and poor mobility, it's not particularly suited to the frontlines and tight spaces. Instead, captains of the ship should provide covering fire for allies from a distance. This is to make yourself a smaller target against ships and give a higher chance to avoid torpedoes as well as the fact the Mark V cannon has good muzzle velocity for attacking distant targets while reducing counter-fire

The Oerlikon guns should concentrate on providing anti-air support as bombers often find the T-285 to be a rather attractive target due to its size but you should also be aware of any enemy motor torpedo boats attempting to deploy their torpedoes on you which is where the Oerlikon guns can be used to counter them, particularly if they are within 1 km or less to you as the Mark V cannon may not have enough time to react to them. One final note about the two Oerlikon guns behind the Mark V cannon is that they have limited negative vertical traverse when pointed towards the bow. As such, when attempting to aim at any close proximity targets in front of you, you will need to turn the ship left or right from the target to give the guns enough depression to aim down at them.

History

Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the ship and adding a block "/History" (example: https://wiki.warthunder.com/(Ship-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the ship's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
