The Attilio Regolo lacks substantial armour opting to use the lack of weight to improve the speed of the ship, this leaves areas such as the engines, ammo, and Bridge susceptible to damage from shells as small as destroyers. However the front of the turrets are protected by 20mm of armour, while the sides and roof are protected by 6 mm of armour. This use of small armour allows the turrets to not be splashed by destroyers high explosive rounds, but direct hits will disable the ships armament. The bridge is also surrounded by 15 mm of armour, which is not reliable in protecting the module. The greatest threat to the survivability of the ship is the exposed torpedoes on the middle of the deck, when hit they will quickly incapacitate the ship, removing the use of almost every module past the bridge, if the player can disengage from combat the ship can be recovered with at best a little over half the crew, but if it happens in the middle of a fight the ship will almost always be unrecoverable from fire, and eventually, flooding.

Mobility

With a max speed of 72 km/h, the Attilio Regolo is tied with the Raimondo Montecuccoli as the fastest cruiser currently in the game. This impressive speed allows the ship to navigate towards advantageous positions before its adversaries.

Armament

Primary armament

4 х Turret2 x 135 mm/45 O.T.O. Mod. 1937 cannon

Ammunition320 rounds

Vertical guidance-5° / 45°

The 8 135 mm/45 O.T.O Mod. 1938 are divided into 4 turrets allowing the ship to use at least half of its armament at any angle. The HE Dirompente is underwhelming with only 23 mm of pen at any angle, and an explosive mass of 1.8 kg. This shell is unreliable and should be avoided after the APHEBC Perforante and the HE-TF Contro-aerea shells are unlocked. The APHEBC Perforante is the most reliable shell used on the Attilio Regolo with a penetration of 174 mm at 1,000 m, and an explosive mass of 1.47 kg. The HE-TF Contro-aerea shell shares almost all of its characteristics with the HE Dirompente, but has a time fuse added to it for use as an AA shell; with its versatility as an anti-air shell and as a normal HE shell, this is the second most reliable shell to have.

Secondary armament

8 х Turret37 mm/54 Breda Mod.39 autocannon

Ammunition1500 rounds

Belt capacity6 rounds

Fire rate200 shots/min

4 х Turret2 x 20 mm/70 Scotti-Isotta Fraschini mod.1939 autocannon

Ammunition4800 rounds

Belt capacity12 rounds

Fire rate230 shots/min

For secondary armament the Attilio Regolo is armed with 8 x 37 mm/54 Breda Mod.39 autocannons, and 4 x 20 mm/70 Scotti-Isotta Fraschini Mod.1939 autocannons in double mounts. These secondary autocannons are effective as anti-air under control of the AI, but will need to be used by the player if they want to be used to destroy torpedo boats effectively.

Torpedo armament

The 533 mm steam-turbined S.I. 270/533,4X7,2 Tipo M torpedoes have an explosive mass of 270 kg, and a range of 12 km at 74 km/h with torpedo mode enabled, while it goes 4 km at a speed of 93 km/h when the torpedo mode is disabled. The torpedoes are best used as a tool to force opponents to avoid areas such as channels. If the player does not use torpedoes often then it is recommended to not bring them as they can be destroyed as an external ammo rack causing catastrophic damage.

Special armament

Depth charges, mines, rocket launchers and missiles are also effective in skilled hands and can take an off-guard opponent by surprise. Evaluate the ammunition of this type of armament and rate its performance in combat. If there are no special armaments, remove this section.

Additional armament

Usage in battles

The general game play of the Attilio Regolo is most similar to a destroyer then a light cruiser. The lack of meaningful armour means that it is fairly weak in a head-on engagement, but they can easily be avoided thanks to its incredible top speed. The ship has two general play styles that fit it well, the first being a light brawler fighting for caps, and the second being a flanking support ship. The main threats to the Attilio Regolo are heavier cruisers than itself, such as the Emden and Trenton, as well as destroyers with higher fire rates such as the Sumner or Tashkent. The best way to counter cruisers such as the Emden is by simply avoiding the conflict using the ships high speed and smoke, or by using the ship's decent torpedo loadout to destroy them when they are unaware of you. Destroyers can best be dealt with by using terrain to your advantage to protect yourself from incoming fire, and retaliate while in safety of islands. The most vulnerable spot of the Attilio Regolo is its extra torpedo storage in the middle of the ship, this can best be protected by keeping the bow of the ship centred on an enemy you are fighting. While being in a broadside allows the ship to bring more of its firepower to use, it also exposes the external torpedoes that can quickly be set off destroying the ship.

History

The Attilio Regolo was a Capitani Romani class light cruiser designed to counter and catch the Mogador, and Le Fantasque class French destroyers in 1939. On November 7th 1942 the ship was torpedoed by the British sub HMS Unruffled, which caused the ship to be dry docked until the armistice with a shattered bow. After the war the Regolo was transferred to the French navy and renamed the Chateaurenault (D 606) as a war reparation, before finally being decommissioned in 1961.
