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 armaments separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips on preserving survivability for the "Usage in battles" section. If necessary, use a graphical template to show the most well-protected or most vulnerable points in the armour.

Armament

Primary armament

Turret57 mm 6pdr 7cwt QF Mk IIA mounting

Ammunition140 rounds

Vertical guidance-10° / 12°

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

Turret2 x 20 mm/70 Oerlikon Mark V autocannon

Ammunition3600 rounds

Belt capacity60 rounds

Fire rate450 shots/min

Some ships are fitted with weapons of various calibres. Secondary armaments are defined as weapons chosen with the control Select secondary weapon. Evaluate the secondary armaments 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 any anti-air armament, even heavy calibre weapons, belong in the next section. If there is no secondary armament, remove this section.

Anti-aircraft armament

2 х Turret2 x 12.7 mm Vickers Mk.V machine gun

Ammunition4000 rounds

Belt capacity200 rounds

Fire rate600 shots/min

2 х Turret2 x 7.7 mm Vickers GO No.5 machine gun

Ammunition4000 rounds

Belt capacity100 rounds

Fire rate949 shots/min

An important part of the ship's armament responsible for air defence. 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 are no anti-aircraft armaments, remove this section.

Additional armament

Setup 12 x 533 mm Mk.VIII torpedo

Setup 22 x Mk.VII depth charge

Setup 32 x 533 mm Mk.VIII torpedo

2 x Mk.VII depth charge

Describe the available additional armaments of the ship: depth charges, mines, torpedoes. Talk about their positions, available ammunition and launch features such as dead zones of torpedoes. If there is no additional armament, remove this section.

Usage in battles

In AB this boat works best when the opposing team has started using aircraft as the boat has good coverage from its secondary and anti-aircraft armaments and is used to provide anti-air cover (with HE rounds equippped) for other more powerful boats. However, given its speed and agility it is good when making breaks for neutralising or capturing points, especially if they are not being guarded by larger more heavily-armoured craft.

The high fire rate and placement of the primary cannon means that it is easy to use and will handle craft of a similar size (plus there is no overheat mechanic). Against larger or more heavily-armoured targets the user should rely on the torpedoes or team mates (especially against craft such as the similary BR rated SF40) as the main cannon is too low caliber to end head-to-head conflicts quickly enough given the lighweight nature of the hull. Against smaller boats such as the Pr.123 or the ubiquitours LS3, it is best the use the secondary or anti-air armaments (especially when the target is within 1.5km) as they are sufficiently powerful to deal with their armour while being able to keep up with these agile craft but a few well place shots at longer ranges from the primary cannon can be very satisfying.

Much like the rest of British coastal boats, this boat is not suited for areas of intense fighting and is best used as anti-air support or when used with hit and run tactics.

Pros and cons

Pros:

• Reasonable anti-air defences
• Fast and agile

Cons:

• Light armour

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).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
