HMS Iron Duke, like other British battleships of this time period, uses a distributed armour scheme. Her main main belt has a thickness of 12 inches, slightly angled to increase effectiveness. This falls off to 9 inches and then 8 inches on the hull, before finally ending with 6 inches on the secondary armour deck. The main belt will be resistant to most battleships of the rank, but the higher ranked ships like the SMS Bayern or IJN Fuso will be able to penetrate it at most ranges, and the thinner armour above the main belt will be easily penetrated by all capital ships. Iron Duke has no dedicated torpedo protection, though it does have coal bunkers which can absorb some hits.

The turrets are fairly well armoured, though not to the extreme of something like the USS Nevada with her 18 inches of angled turret armour. HMS Iron Duke has 2 layers of turret armour, with the first coming in at 11 inches of armour, covering the front, rear and sides and a second 3-inch layer contained within. This should be more than enough armour to stop most shells at anything but extremely close range. The top of the turrets also have multiple layers of armour, with both a 3-inch and 4-inch plate protecting from plunging fire. The turret barbette armour ranges from 9-10 inches, which unfortunately means that every battleship will easily be able to destroy the ammo elevators, though these won't explode when hit. The magazines are placed well below the waterline, and have multiple layers of deck armour to detonate plunging fire and shield the magazine from hits, with two 1-inch and a 1.25-inch plate providing ample protection.

Secondary armament

12 х Turret6 inch/45 BL Mark VII cannon
Ammunition130 rounds

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 Turret4 in/45 QF Mark V cannon
Ammunition200 rounds

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 120 x 533 mm Mk.IV torpedo
Main article: Mk.IV (533 mm)

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

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 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

Summarise 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 - use substitutions with softer forms such as "inadequate" and "effective".




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: 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).


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