The Flower-class, HMCS Brantford (K-218) is a rank II British sub-chaser 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

Flower class (K-218) internals (starboard side).

Flower class (K-218) has the following armour layout:

• 102 mm BL Mark IX gunshield: 4.97 mm, antifragmentation armour
• 40 mm 2pdr QF Mk.VIII gunshield: 12.7 mm, hardened armour
• 20 mm/70 Oerlikon Mk.II gunshields: 12.7 mm, hardened armour
• Hull: 6 mm, steel
• Superstructure: 4 mm, steel

While the gunshields may stop low-calibre machineguns, heavy machineguns and cannons will have no trouble with them at any range. The hull and superstructure are cannot stop gunfire of any sort.

There is currently no gun in the game that can hull-break Flower class (K-218).

Flower class (K-218)'s hull is split into five compartments. The first compartment starts at the bow and ends in front of the 102 mm BL Mark IX cannon. The second starts at the 102 mm BL Mark IX cannon and ends in front of the fuel tanks. The third starts at the fuel tanks and ends where the fuel tanks end. The fourth starts at the end of the fuel tanks and ends at the aft 40 mm 2pdr QF Mk.VIII cannon. The fifth starts at the aft 40 mm 2pdr QF Mk.VIII cannon and ends at the stern. Flower class (K-218) is notable for being one of the only rank I boats to have the "Shrapnel Protection" modification, though this doesn't affect survivability much.

Flower class (K-218) has two types of ammunition storages: a "Shells room", located in the second hull compartment, and an "Ammunition storage", located in the fifth hull compartment. The "Shells room" contains ammunition for the 102 mm BL Mark IX cannon, and the "Ammunition storage" contains ammunition for both the 40 mm 2pdr QF Mk.VIII and 20 mm/70 Oerlikon Mk.II cannons. Destroying either will cause any remaining ammunition for the respective guns to be destroyed, but doing so will not immediately destroy Flower class (K-218).

With a crew complement of 85, Flower class (K-218)'s overall survivability is very high.

Armament

Primary armament

The primary armament consists of a single 102 mm BL Mark IX cannon mounted on the bow. There are 150 rounds of ammunition available for it. Stock, the mount can traverse horizontally at a rate of 13°/s and vertically at a rate of 8.5°/s; with the "Primary Armament Targeting" modification installed, this is increased to 15°/s and 10°/s respectively. 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

The secondary armament consists of a single 40 mm 2pdr QF Mk.VIII cannon mounted aft. There are 3,920 rounds of ammunition available for it. Stock, the mount can traverse horizontally at a rate of 38°/s and vertically at a rate of 30°/s; with the "Auxiliary Armament Targeting" modification installed, this is increased to 45°/s and 35°/s respectively. The gun has a belt capacity of 56 rounds and a rate of fire of 200 rounds/min. With a stock crew, it can be reloaded in 6 seconds; with an aced crew it can be reloaded in 3 seconds.

Anti-aircraft armament

The anti-aircraft armament consists of two 20 mm/70 Oerlikon Mk.II cannons in single mounts, one on either side of the bridge. There are 2,400 rounds of ammunition available for each mount for a total of 4,800 rounds. There are no stated traverse rates for these mounts listed in-game, though they handle very similarly, if not identically, to other single 20 mm/70 Oerlikon Mk.II mounts in the game, all of which handle as follows: stock, they can traverse horizontally and vertically at a rate of 64°/s; upgraded (with the "Anti-Air Armament Targeting" installed in Flower class (K-218)'s case), they can traverse horizontally and vertically at a rate of 75°/s. Each gun has a belt capacity of 60 rounds and a stated rate of fire of 450 rounds/min, though in actuality, they fire at slightly different rates: the starboard gun fires at a slightly lower rate, around 420 rounds/min, while the port gun fires at a slightly high rate, around 480 rounds/min. With a stock crew, both guns can be reloaded in 5.2 seconds; with an aced crew, they can be reloaded in 4 seconds.

Turrets are named sequentially, clockwise, starting at the bow.

There are no ammunition choices available for this gun on Flower class (K-218).

Special armament

Flower class (K-218) has four loadout options:

1. Without load
2. 20x Mk.VII depth charges
3. 4x Y-gun Mk.VII depth charges
4. 20x Mk.VII depth charges, 4x Y-gun depth charges

The Mk.VII depth charges are carried on the aft of the boat and are split into two chutes, each with 10 depth charges. The depth charges are dropped one at a time starting with the starboard chute, then continuing on to the port chute after all 10 in the starboard chute have been dropped.

The Y-gun Mk.VII depth charges are fired from four depth charge throwers mounted amidships, two on either side facing outwards. These depth charges are fired depending on the direction the player is currently looking. Although the two depth charges on each side are usually both fired together, at certain camera angles, they can be fired independently.

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

History

Just prior to WW2, it became apparent that German U-boats would present a serious threat to British transatlantic shipping in the event of an outbreak of hostilities. Realizing this, it became clear to the Royal Navy that they needed a large number of new small vessels that could cope with this threat, whilst being cheap, simple and quick to produce, without hindering the construction of larger warships.

In response to the demand, the Smiths Dock Company proposed a modified version of one of their 700-ton whale catchers. The proposed ship virtually met all Royal Navy requirements and could even be built by smaller shipyards across the country, meaning that a large-scale production wouldn’t affect the construction of larger warships. The proposed design was accepted and the first orders for Flower-class corvettes came in as early as July 1939.

Although initially only intended to operate along the British coast line, the large range and robust seaworthiness of the Flower-class corvettes soon saw ships of this class escorting Atlantic convoys to and from Great Britain. Their primary role was to fend off submarines, which is why ships of this class were relatively lightly armed and often specialized in anti-submarine warfare.

Apart from Great Britain, Flower-class corvettes were used extensively in various different roles by numerous other nations during WW2, including the United States, France, Canada, Greece, the Netherlands and many more. Ships of this class served right up until the end of WW2, even when more advanced designs began to replace them.

Whilst Spitfires and Hurricanes kept the Luftwaffe out of British skies, the venerable Flower-class corvettes ensured that vital supplies reached Great Britain, by fighting off the German submarine wolf-packs throughout the war. With over 260 ships built, the Flower-class corvette remains one of Britain’s most mass-produced wartime ship type, whose contribution to the war effort is highly obvious.
