The Dark Class, Dark Agressor (FPB 1102) is a rank II British motor torpedo boat with a battle rating of 2.3 (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

Being a light torpedo boat, the Dark class is an entirely unarmoured vessel, lacking even a gun shield for the 40 mm cannon. That being said, survivability is somewhat surprisingly good for an MTB, having an above-average number of crewmen, 15 members are spaced in both the hull and superstructure will give you enough time to respond to immediate danger should you come across it. This does not mean that you can afford to take fire in the Dark Class, just that you might have time to escape or defeat the enemy ship before it gets you. It compares favourably with American and Russian MTBs, however, the Dark class lacks the sheer numbers of crew members which the S-boat series has. Take this into consideration if you are starting from one of these countries.


The Dark Class maintains excellent manoeuvrability with high top speed and a small turn radius. Acceleration and Deceleration are both very impressive and contribute to the all-round good mobility of this vehicle. Once again the similarity to American MTBs comes into play, meaning players coming from the US tree will feel right at home with the Dark class. This isn't so much the case for Russian and German players as the Dark class has much lower and higher performance than their counterparts respectively.


Primary armament

Main article: QF Mark VII (40 mm)

Despite what the name might make players assume, the QF Mk.VII is in fact a Bofors 40 mm gun. Easily being one of the greatest weapons a captain of War Thunder can use, the Bofors cannon combines fire rate, accuracy and power into a single incredible weapon. Its high reloading speed allows for a near-constant stream of fire as you pump shells into your enemies. The shells themselves are devastating against small boats with the Universal and AP belts, allowing for an excellent combination of penetration against components and HE to start fires or deal damage to deck mounts. Attention must be paid to overheating, however, as jamming does occur if sustained fire (usually against large gunboats or early destroyers) is prolonged.

Torpedo armament

Main article: Mark VIII

The Dark class is equipped with four torpedoes in an angled forward mounting setup, akin to many American or Soviet MTBs. Their placement allows for releasing torpedoes with relatively little adjustment and captains can become extremely proficient in the wiggling pattern necessary to drop multiple torpedoes should they use the Dark Class. The torpedoes themselves are quite average with high speed and relatively short-range when stock level and becoming very average in these metrics with the torpedo mode upgrade installed. The 327 kg warhead of TNT is quite effective at dealing with anything short of a cruiser and able to hull break ships with one torpedo which might not be possible with American or Soviet-style torpedoes.

Special armament

Main article: Mk.VII depth charge

The Dark Class is equipped with two standard depth charges with each of which containing 130 kg of explosives. Should captains of the Dark Class manage to close the distance on a destroyer, they can destroy them by dropping them directly next to the turrets of their target (within 5 meters of the hull preferably).

Usage in battles

With the Dark Aggressor class, the tactics are in the name. Use the ship's high mobility to reach capture points quickly, subduing any targets on the way with the Bofors 40 mm, and then continue to advance either into their spawn, cargo ship area (on encounter mode) or into channels where Destroyers will enter the small boat areas. Torpedo and depth charge these ships from the safety of cover to secure victory. Pushing into open water is possible, however not recommended due to the accuracy of secondary armament gunners and the poor survivability to high calibre HE fire.

Pros and cons


  • Fast firing 40 mm cannon
  • 4 x torpedoes
  • Fast speed for a water vehicle


  • Low survivability compared to German and Japanese motor torpedo boats of the same rank
  • Torpedoes are average once upgraded and suffer from short range stock


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 big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article.


An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
