General info

Survivability and armour

Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armament separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Tips for preserving survivability should be saved for the "Use in battle" section.

If necessary, use a graphic template to show the most well-protected or most vulnerable points in the armour.


Write about the ship’s mobility. Evaluate its power and manoeuvrability, rudder rerouting speed, stopping speed at full tilt, with its maximum forward speed and reverse speed.


Primary armament

Provide information about the characteristics of the primary armament. Evaluate their efficacy in battle based on their reload speed, ballistics and the capacity of their shells. Add a link to the main article about the weapon: {{main|Weapon name (calibre)}}.

Broadly describe the ammunition available for the primary armament, and provide recommendations on how to use it and which ammunition to choose.

Secondary armament

Some ships are fitted with weapons of various calibres. Secondary armament is defined by the weapon chosen with the control Select secondary weapon. Evaluate the secondary armament and give advice on how to use them. Describe the ammunition available for the secondary armament. Provide recommendations on how to use them and which ammunition to choose. Remember that anti-air armament, even heavy calibre weapons, belong in the next section.

If there is no secondary armament, remove this section.

Anti-aircraft armament

An important part of the ship’s armament responsible for air raid defense. Anti-aircraft armament is defined by the weapon chosen with the control Select anti-aircraft weapons. Talk about the ship’s anti-air cannons and machine guns, the number of guns and their positions, their effective range, and about their overall effectiveness – including against surface targets.

If there is no anti-aircraft artillery, remove this section.

Torpedo armament

Many ships are armed with torpedo launchers, and for some vessels such as boats, torpedoes are an extremely important means of defeating an opponent. Evaluate the position of the torpedo launchers, discuss the ammunition available, firing specifics such as dead zones, features of the torpedoes themselves, etc.

If there is no torpedo armament, remove this section.

Special armament

Depth charges, mines, rocket launchers and missiles are also effective in skilled hands and can be an unexpected surprise for an opponent. Evaluate the ammunition of this type of armament and rate its performance in combat.

Usage in battles

Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don’t get try to provide a single point of view, but give the reader food for thought. Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).

Pros and cons

Summarize and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - they have a substitution in the form of softer "inadequate", "effective".




In 1940, the Admiralty issued a set of requirements for a new gunboat design that would incorporate features from both motor torpedo boats and gunboats. The primary task of this new vessel would be to counter the German S-boat threat and to protect the British coastline in areas where larger vessels, such as destroyers, couldn’t operate.

With WW2 already in full swing, the need for this kind of vessel was considered high and an emphasis was put on ease of mass-production, in order to manufacture as many ships as quickly as possible.

The Denny company was tasked with designing a vessel around the Admiralty's specifications. They armed the vessel, similar in design to the contemporary Fairmiles, with cannons, machine guns and torpedo tubes, decided to construct it from steel so as to make it fit for mass-production, but soon ran into a serious problem.

The conventional power supply of the time came from either petrol or diesel engines, neither of which was readily available in wartime Britain. Thus, the decision was made to outfit the new vessel with two steam turbines, producing 4,000 horsepower each.

The Admiralty approved the design and ordered an initial nine vessels to be produced, whilst a total of sixty were planned. However, these plans were soon dropped and out of the nine vessels that were laid down, seven actually saw completion.

Nonetheless, the seven ships that did come out of the shipyards proved themselves in combat, despite some endurance and efficiency problems presented by the steam propulsion system. Thanks to their heavy armament, they quickly gained respect from German S-boat captains, who often tried to avoid encountering an SGB.

Only a single SGB was lost in combat during WW2, with the majority serving into the Cold War before being decommissioned from service.
