RN Duilio

Description
The Duilio-class, RN Duilio, 1942 is a rank VI Italian battleship with a battle rating of 6.7 (AB/RB/SB). It was introduced in Update "Sky Guardians".
The RN Duilio, also known as the Caio Duilio, is the sister ship of the previous battleship in the tech tree, Andrea Doria. Built in the dreadnought era, the vessel saw no action in the first world war due to allied naval supremacy the Mediterranean. What makes this vessel special is the refit given to it during the interwar years. Due to a lack of other options, the Italians gave the old Conte di Cavour class and Andrea Doria class battleships the most extensive modernisations that were ever given to any dreadnoughts, resulting in vessels that were almost unrecognisable as compared to before, which you can see by comparing the Andrea Doria and Duilio in game.
The refit for this vessel consisted of: Extensive modifications to the hull including a rebuild of the bow and stern, lengthening the ship by almost 11 metres, two propeller shafts were removed, the old turbines were replaced by new geared-turbines, the aging machinery, powerplant and all 20 old boilers were ripped out and replaced with modern systems and 8 new superheated oil-fired boilers, while the amidships main battery turret was taken out to make way for an entire rearrangement of the machinery and funnels, increasing the maximum speed by about 10km/h. The remaining main guns were bored out an extra 15 mm to allow the guns to fire heavier 320 mm shells, the turrets were retrofitted with electric power and their maximum elevation was increased, the obsolete torpedo tubes were removed, a number of 37 mm and 20 mm anti-air guns were added, the old casemate 152 mm guns were torn out and replaced with four forward-facing triple 135 mm turrets and a number of dual-purpose single-gun 90 mm turrets which were placed along the side of the superstructure, which itself was also completely rebuilt, including a new conning tower and modern rangefinding systems. The deck armour was increased to a total of 135 mm and a Pugliese torpedo defence system was installed.
The RN Duilio took part in a number of activities during WW2, though the ship never got a chance to engage another surface target and arguably the most interesting part of its service life was when it was torpedoed in Taranto by the British. The ship continued serving in the Italian navy after the war and was decommissioned in late 1956, being sold for scrap the next year.
General info
Survivability and armour
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.
Mobility
Write about the ship's mobility. Evaluate its power and manoeuvrability, rudder rerouting speed, stopping speed at full tilt, with its maximum forward and reverse speed.

Armament
Primary armament
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
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
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.
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".
Pros:
- Turret barbettes are protected by two layers of steel, giving a total of 290+ mm armour thickness. The magazines are also well protected
- Relatively fast and manoeuvrable (compared to previous dreadnoughts)
- Good 5°/sec traverse rate on main turrets
- 320 mm APCBC shell features outstanding ballistic characteristics and high penetration
- Decent AA capability
Cons:
- Crew compartments are compact and cramped in midship (at second deck level), taking hit will result in heavy crew loss
- 90 mm turrets can easily be taken out by HE splash and rapid lower calibre hits
- 320 mm gun dispersion is high for a large-calibre naval gun
- Low ammo capacity, 65 rounds per gun is not sufficient in a prolonged battle
- Very poor bursting charge for the main calibre AP shells
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).
