World of Warships Final Review: Italian Tier X Destroyer Attilio Regolo

7 min read

The early access period for Italian destroyers will soon begin as Update 0.11.2 is just around the corner. It is now time to have a look at what you will be grinding for with the Attilio Regolo.

Historical background

Attilio Regolo was the first ship of the Capitani Romani-class of light cruisers from the Regia Marina. The ship was laid down in September 1939, launched in August 1940 and commissioned in May 1942.

The Capitani Romani-class were meant to counter the French contre-torpilleurs of the Le Fantasque and Mogador-class. The ships were essentially small light cruisers stripped of any sort of armor in exchange for a speed of 41 knots and a main battery of eight 135 mm guns in four twin turrets.

Attilio Regolo herself… didn’t really have what you would call an amazing career. Only seven months after her commissioning, while returning from a mine-laying operation, the ship was torpedoed by the British submarine HMS Unruffled (I learned a new word today thanks to this submarine). The hit broke the bow of Attilio and she was brought into a drydock for repairs. She was brought back to action in May 1943… just to see the Armistice happening in September. Attilio was sent to Port Mahon where she was interned until the end of the war.

It will be in French services that she will start a new career alongside her sistership Scipione Africano. Both of them had their armament heavily altered with them being equipped with three twin 105 mm turrets, five twin 57 mm AA mounts and four triple torpedo launchers. Attilio Regolo was renamed Châteaurenault and would serve until 1962. She was later used as a school for the “Fusilier marins” (Navy riflemen) until she was fully decommissioned and scrapped in 1969.

  • The torpedoes deal low damage
  • Very slow torpedoes
  • Large target and sits especially high on the water

  • Poor concealment

The camouflages

The permanent camouflage of the Attilio Regolo provides the classic bonuses for tier X ships:

  • -3% to surface detectability range
  • +4% to maximum dispersion of shells fired by the enemy at your ship
  • -50% to the cost of ship’s post-battle service
  • +20% credits earned in the battle.
  • +100% to experience earned in the battle

Sitting at the pinnacle of the Italian destroyers line, Attilio Regolo presents herself as a particularly strong gunboat destroyer with a very interesting kit that makes her stand out compared to the other tier X gunboats.

Thanks to her speed that can reach over 53 knots as well as the Exhaust Smoke Generator, Attilio Regolo has the capacity to decide what she wants to engage. She can easily catch up on enemy destroyers even while taking into account her poor concealment (7.21 km when fully specced) and she can just as well instantly bail out from fights that wouldn’t be advantageous with the smoke.
The said smoke can obviously also be used to go gun blazing at your targets while staying undetected and as such, avoid taking unnecessary damage.

In the early game, it is generally better to take a somewhat passive approach unless you are on a flank where you have room to bail out or if you are sure that there isn’t a radar ship around to kill your escape in the egg. After that, you can either go gunboating in the open on cruisers and battleships or you can stay around capture point and slap destroyers with your impressive firepower.

Another thing that you can consider doing, although with less effectiveness, is roleplaying a Paolo Emilio and drive-by ships with torpedoes while using your smoke and engine boost. Just make sure that the target is low enough to die from that pass as the torpedoes deal low damage.

If you want to see the ship in action, here is the replay of one of my games:

Here are also the post-battle results.

Ricochet Angles60° – 75°

The firepower of the Attilio Regolo is definitely something that one has to acknowledge. Its only real downside is that the Main Battery and AA Expert skill is mandatory if you want to have a minimum of freedom of movement.

While the range of this main battery will limit your options when engaging targets, the damage output is fantastic. Thanks to the combined high alpha damage of the SAP shells and the eight guns broadside, getting 6k volleys or more on targets will be far from rare and the 38 mm of penetration allows you to effectively damage a wide variety of targets.
The HE shells aren’t anything to ignore and will be a valuable ammo type when dealing with angled targets. The damage output is solid as well and with the volume of fire, the fire starting capacity is not bad either.

Torpedo Armament

2 x 4 533 mm tubo lanciasiluri
533 mm Si 270 M2
Reloading Time90 s
Maximum Distance13.500 km
Firing angles at the Front60°
Firing angles at the Rear56°
Damage13 900
Flooding Chance230%
Speed56 knots
Surface Detectability1.0 km

The torpedo armament of the Attilio Regolo, while being more of a side dish, is still an incredibly valuable tool.

Even though these torpedoes are limited by their low speed and damage, their combined fast reloading time, range and amazing detectability make them a very reliable zoning tool. When it comes to the speed, it is a curse when trying to use these torpedoes in heated situations, but it is a blessing when kiting at a safe distance. Due to the time the torpedoes take to travel, when they arrive on target, the enemy ships basically forgot about them. Also, the range has the usual effect of giving you the most random torpedo hits on ships that were not your initial target.

Anti-air Armament

4 x 1 65 mm/64 Model 1939 on a Model 1939 mount
4 x 1 37 mm/54 Model 1939 on a Model RM1939 mount
Sector range0.1 km – 3.7 km
Hit chance100 %
Sector’s damage44
Sector’s damage frequency0.29 s
Sector’s damage per second154
4 x 6 20 mm/70 Breda Model 1941 on a sextuple mount
Sector range0.1 km – 2.0 km
Hit chance95 %
Sector’s damage19
Sector’s damage frequency0.29 s

It… exists. Like seriously, if a carrier comes on you, the Exhaust Smoke will be your best friend.

Final Opinion

Attilio Regolo is definitely a very strong destroyer. Her firepower allows her to bully most destroyers she will come across and she will also be able to fight on even ground against the likes of Marceau, Harugumo, etc. Her consumables also give her incredible flexibility when it comes to engaging targets or disengaging in case a fight doesn’t go as planned.
One thing is for sure, she will definitely suffer from the lack of range of the main battery in certain situations. However, it’s a fair sacrifice for such a potent toolkit at the range she has to work with.

Also, Attilio Regolo will be disgustingly effective in a division with a radar cruiser to obliterate enemy destroyers. I could even mayyyyybe see her being useful in competitive in an anti-destroyer role but unlike a Ragnar or Smaland, she would have a much more limited role, again, because of the lack of range on top of the heavy presence of radar ships.

Recommended Build

For the Attilio Regolo, I recommend the following commander build and upgrades:

I also recommend using the commander Luigi Sansonetti, especially for the Far Reach talent that compensates the main downside of this Italian destroyer line.

This concludes my review of the Attilio Regolo. Thank you for reading this article!
