Description

The SGB Grey Fox (S304) is a rank IV British motor gun boat with a battle rating of 3.0 (AB/RB/SB). It was introduced in Update 1.83 "Masters of the Sea" as part of the British fleet closed beta test.

The SGB (Steam Gun Boat) Grey Fox, pennant number S304, was a gun boat built for the Royal Navy's coastal forces during the early stages of World War II. While limited in historical quantities, the Grey Fox is a formidable boat within the game. This is thanks to a plentiful variety of armaments covering the steam-powered boat from prow to stern.

With few cons, this SGB engages with ease most boats that are equally sized and smaller than her. Although, the large hull and not excellent top speed makes her the perfect target for destroyers, frigates, and gunboats. After learning how to handle these limitations, captains are likely to master this well-armed boat.

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.

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

Pros:

  • Adequate top speed for a steam-powered gun boat
  • 2 sets of 40 mm 2pdr guns, a 76 mm gun and 20 mm Oerlikons cannons are great firepower
  • Wide variety of auxiliary firepower (12.7 mm Vickers MGs, mines and torpedoes)
  • Armour plates protect the engine compartment quite effectively from HE and Shrapnel
  • Above-average crew count becomes an advantage versus smaller crafts

Cons:

  • Speed is no match to other vessels at the rank as Sparviero, Pr.183, or PG 02
  • Large size; easy to target and difficult to manoeuvre around shores

History

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.
