Description
The Capitani Romani-class, RN Attilio Regolo, 1942 is a rank III Italian light cruiser with a battle rating of 4.7 (AB/RB/SB). It was introduced in Update "Starfighters".
The Attilio Regolo is a Capitani Romani-class scout cruiser that blurs the line between cruisers and destroyers. She is very large and heavily armed compared to destroyers, and at the same time is significantly faster than but lacks the armour protection of most cruisers.
General info
Survivability and armour
The Attilio Regolo's hull lacks any substantial armour, with the design emphasizing speed instead. This leaves areas such as the engines, ammunition magazines, and the bridge susceptible to damage from even destroyers' shells. However, the front of the turrets are protected by 20 mm of armour, while the sides and roof are protected by 6 mm of armour. This protects the turrets from nearby explosions from destroyers' high explosive rounds, but direct hits will disable the ship's armament. The bridge is also surrounded by 15 mm of armour, which is not reliable in protecting the module.
The greatest threats to the survivability of the ship are the exposed torpedo tubes and spare torpedoes amidships and the highly exposed ammunition magazine under the 'X' turret. The former can detonate when hit and quickly incapacitate the ship, removing the use of almost every module past the bridge. However, this can be avoided by either firing off the torpedoes as soon as possible or not bringing them at all. The ammunition magazine will also detonate when hit, which will immediately destroy the ship. It is not possible to empty or redistribute the ammunition held here, and thus the only protection is to avoid getting hit there at all.
Mobility
Thanks to its four Thornycroft boilers and four Parsons turbines which together deliver 110,000 hp, the Attilio Regolo can reach a top speed of 72 km/h forward and a maximum reverse speed of -25 km/h. With these powerful engines the acceleration is also very good: it can reach top speed in about 30 seconds. Unfortunately, due to its length it does not excel in manoeuvrability, completing a full circle in 1 minute 25 seconds.

Armament
Primary armament
The 8 x 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
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.
Additional 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.
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.
Basically, the RN Attilio Regolo is an excellent light support cruiser. It can provide an excellent anti-aircraft barrage with its effective 20 and 37 mm turrets. The Attilio Regolo can also provide support fire against small and medium-sized vessels making life easier for ships with longer reloading times. It is recommended to use this ship in the second and third line, supporting heavy cruisers and dreadnoughts, and even with good survivability the ship alone will not be as effective as when in a group.

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.
Devblog
During the 1930's, the Regia Marina was looking into building a type of 'ocean scout' vessel. Initially, the design work took inspiration from the Condottieri-class cruisers, but was soon abandoned in favor of a more compact and modern design. By the end of the decade however, the need for 'scout' vessels became somewhat redundant thanks to the advances in aviation and radar technology. As a result, the design was reclassified as a light cruiser and would serve as a flotilla leader.
Plans were made for the construction of 12 vessels of the 'Capitani Romani' class of light cruisers, all of which were laid down in various Italian shipyards in September and October of 1939. However, only three ships of the class would actually see completion while the others either had their construction cancelled or were later on captured in drydock by German forces.
One of the ships which did see completion is the Attilio Regolo, which entered service with the Regia Marina in May 1942. However, the ship's didn't see extensive service not only due to joining the war late, but also because it was hit by a torpedo from British submarine HMS Unruffled in November of the same year, getting severely crippled.
Postwar, Attilio Regolo was handed over to France in 1948 as war reparations and subsequently entered service with the French Navy as 'Châteaurenault'. The ship went on to serve with the French Navy until the early 1960's, before being decommissioned and sold for scrap in the 1970's.
