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.

Armament

Primary armament

4 х Turret2 x 135 mm/45 O.T.O. Mod. 1938 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 auto cannon
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.

Additional armament

Setup 112 x 533 mm steam turbined torpedo S.I. 270/533,4X7,2 Tipo M
Setup 240 x Bollo P.200/1936 moored contact mine
Setup 312 x 533 mm steam turbined torpedo S.I. 270/533,4X7,2 Tipo M
2 x Bollo P.200/1936 moored contact mine

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.

Pros and cons

Pros:

  • High top speed
  • Effective torpedo count with a reload
  • Effective turret layout with good firing angles

Cons:

  • Low survivability
  • Lowest crew count on a cruiser
  • Lack of armour
  • Inadequate fire rate
  • Low calibre main armament

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.

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.
