Description

The RN Duilio, also known as the RN Caio Duilio, is the sister ship of the previous battleship, RN Andrea Doria, laid down on 24 February 1912, launched on 24 April 1913, and completed and entered into service on 10 May 1915. The ship took part only in exercises, the ship did not see any operations or missions because naval supremacy in the Mediterranean was in favour of the Allied Powers. It was later refitted in the Ansaldo Shipyard in Genoa from 1937 until her return to service on 15 July 1940. The RN Duilio got one of the most extensive modernisations that was ever given to a dreadnought, including changes to the hull, powerplant, and armaments, resulting in a vessel that was almost unrecognisable as compared to before. The RN Duilio took part in several 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 Royal Navy. The ship continued serving in the Italian Navy after the war and was decommissioned in late 1956, being sold for scrap the next year.

Introduced in Update "Sky Guardians", RN Duilio is in its 1942 configuration. The ship's armament is strong, the main armament consisting of ten 320 mm guns with high penetration AP shells, a secondary armament of four 135 mm twin turrets, useful for destroying smaller targets such as destroyers and cruisers, and finally the anti-aircraft armament that in comparison to the RN Andrea Doria has been greatly enhanced, consisting of ten 90 mm cannons, nineteen 37 mm cannons and finally eight twin 20 mm cannons, provides decent protection from enemy aircraft. Its manoeuvrability and speed is also not bad for a battleship.

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.

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

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

Launched on 24 February 1942, launched on 24 April 1913 and completed and entered service on 10 May 1915, the ship only participated in exercises, later to be rebuilt at the Ansaldo Shipyard in Genoa from 1937 until her return to service on 15 July 1940.

The RN Duilio, also known as the Caio Duilio, is the sister ship of the RN Andrea Doria. Built in the Dreadnought era, the ship did not enter the action in World War I due to Allied naval supremacy in the Mediterranean. What makes this ship special is the refit it underwent in the years between the wars. Due to the lack of other options, the Italians gave the old battleships of the Conte di Cavour class and the Andrea Doria class the most extensive modernisations ever made to any dreadnought, resulting in ships that were almost unrecognisable from before.

She was later rebuilt at the Ansaldo shipyard in Genoa from 1937 until her return to service on 15 July 1940.

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 removed, the old turbines replaced by new geared turbines, the ageing 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, several 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 several 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 several 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.
