Supertest: Italian Tier X Destroyer Attilio Regolo
4 min read
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.

For the classic reminder, this is a ship in testing, anything can change so don’t look at her like she would already be released.

Personal Opinion
As of right now, Attilio Regolo seems to be a really potent gunboat destroyer. Considering the DPM and even the actual alpha damage per salvo, other destroyers engaging this ship will be toying with fire. Kléber or Smaland might be able to hold their ground but they will take a serious beating nonetheless. I’m definitely looking forward to seeing the ship in action, I can tell you that.
Just like the previous ships, the range is an issue but at least, Main Battery and AA Expert is a thing and Italian ships can have Sansonetti as captain.
As a side note, her torpedoes, while not being deep water ones are incredibly stealthy in a similar fashion to those of Khabarovsk. The damage is low but at least they will not be easy to dodge.
