Description

The Iron Duke-class, HMS Marlborough (66), 1927 is a rank VI British battleship with a battle rating of 6.7 (AB/RB/SB). It was introduced in Update "Ground Breaking".

The Marlborough is an Iron Duke-class battleship, the last of the British so-called "super dreadnoughts" to be armed with the 13.5-inch guns. They were the most advanced battleships in service with the Royal Navy at the outbreak of World War I, featuring significantly larger guns than contemporary German dreadnoughts.

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

5 х Turret2 x 13.5 inch/45 Mark 5(H) cannon

Ammunition200 rounds

Vertical guidance-3° / 20°

The Marlborough is armed with ten BL 13.5-inch Mark V (H) guns distributed in five twin turrets. Four of these located in the bow and stern, two each, while the fifth turret is located amidships. All are located in the centreline, allowing all main guns to be used in a broadside. They have a maximum rate of fire of 2 rounds/minute with an ace crew. All turrets have +/-150 degrees of traverse, although the amidships turret has somewhat more restricted firing arcs because of the superstructure. Unlike the preceding Dreadnought, the Marlborough has a modern director fire control system that is considerably more accurate and computes firing solutions faster.

The main guns have a choice of four shells: HE, APC Mark Ia, CPC, and APC Mark IIIa. The HE shell has a massive explosive filler of ~88 kg of TNT equivalent. It is capable of inflicting devastating damage against lightly armoured targets such as destroyers and some light cruisers. The APC Mark Ia has a larger explosive filler (~22 kg TNT equivalent) but less penetration, while the later APC Mark IIIa trades a smaller explosive filler (~16.5 kg TNT equivalent) for more penetration. They are most effective against heavier armour, such as on battleships or armoured cruisers. The CPC is a semi-armour piercing round, combining a respectable amount of penetration with a significantly larger explosive filler (~58 kg TNT equivalent) than the APC ammunition. It is most effective against cruisers, but lacks the penetration to get through battleship belt armour.

Secondary armament

12 х Turret6 inch/45 BL Mark VII cannon

Ammunition130 rounds

The secondary armament of the Marlborough consists of twelve BL 6-inch Mark VII guns located in six casemates on each side of the hull. These have a maximum rate of fire of 7 rounds/minute with an ace crew.

The secondary guns can fire HE or CPC shells. Both shells have fairly large fillers of ~6.6 kg and ~3.7 kg of TNT equivalent, respectively. They are effective against destroyers and can even inflict considerable damage on lightly-armoured cruisers.

Anti-aircraft armament

4 х Turret4 in/45 QF Mark V cannon

Ammunition200 rounds

The anti-aircraft armament of the Marlborough consists of only four QF 4-inch Mark V guns. Two of these are mounted on each side of the bridge conning tower, with another two mounted beneath the aft mast. These do not have a choice of ammunition, firing only HE shells, which severely restricts their effectiveness against aircraft.

Additional armament

Setup 120 x 533 mm Mk.IV torpedo

The Marlborough has four 21-inch fixed underwater torpedo tubes. These are located in front of the bow turrets and behind the stern turrets, one facing each side of the ship. These fire the 21-inch Mark IV torpedo, which has a speed and range of 65 km/h and 7.3 km. It is armed with a 234 kg TNT warhead.

Usage in battles

The Marlborough relies on her powerful 13.5-inch main gun battery to inflict heavy damage on enemy vessels from long range. Her HE shells have the largest explosive filler of any shell currently in the game, while the CPC semi-armour piercing round is a lethal threat to cruisers with its blend of decent penetration and potent explosive filler. The AP shells are nothing to sneeze at, either, thanks to their good penetration and respectable fillers. The powerful secondary 6-inch guns are also quite capable of defending the Marlborough against most destroyers and smaller craft that get into range. Manually controlling the secondary guns while waiting for the main guns to reload is also helpful for supplementing the damage output of the Marlborough.

The armour protection on the Marlborough is adequate, but can be improved dramatically by taking advantage of her good main gun traverse arcs to angle the armour. This is particularly important when engaging other battleships, as the upper belt armour is fairly thin, and she does not have a torpedo belt to help break up enemy shells like on the Wyoming or Parizhskaya Kommuna.

The greatest weakness of the Marlborough is her non-existent anti-aircraft defences. Like almost all World War I era ships, she has nearly no anti-aircraft guns and relatively thin deck armour, making her vulnerable to large bombs. She also completely lacks any torpedo bulges or protection, and is thus also very vulnerable to both ship and air launched torpedoes. She is completely reliant on allied cruisers or more modern battleships such as the Scharnhorst or Parizhskaya Kommuna to provide anti-aircraft protection.

Pros and cons

Pros:

• Thick belt armour
• Large explosive fillers in HE and CPC shells
• Heavy 6-inch gun secondary battery
• Above average crew count
• Heavily armoured main gun turrets and bridge conning tower

Cons:

• Below average manoeuvrability
• Fixed torpedo tubes
• Thickest part of belt armour is submerged below the waterline
• Non-existent anti-aircraft armament
• No torpedo protection
