Conte di Cavour — Italian Tier V battleship.

Battleships of the Conte di Cavour class were armed with 13 main battery guns placed in twin- and triple-gun turrets. The lead ship of the series participated in the capture of Corfu in 1923. Later, she was modernized and received a new propulsion unit as well as a new bow section grafted over the existing bow. During World War II, she took part in the battle of Punta Stilo. In 1940, during a British air raid on Taranto, she received a torpedo hit and sank.

Performance

Warning. The data presented in the AA Defense sidebar section may be incorrect.
Refer to the in-game Port screens for more useful data.

Pros:

Second largest main battery broadside in tier/class with thirteen (13) guns, just behind Agincourt
SAP shells are excellent against lightly armored targets
Thick hull and deck armor, Cavour is very tough when properly angled
Good firing angles, can unmask all guns without showing too much broadside
Good turn radius and rudder shift for a battleship
Excellent concealment
Built-in -30% shell swap time

Cons:

Second smallest health pool among Tier 5 battleships
Slow main battery traverse speed
Longer than average main battery reload speed
Poor accuracy
Main guns do not have access to HE shells
Weak AA defenses.

Optimal Configuration

Upgrades

The recommended upgrades for Conte di Cavour are as follows:

Slot 1: This slot is most commonly filled with Main Armaments Modification 1 , though Auxiliary Armaments Modification 1 is a popular pick for captains who go for a full secondary build with other upgrades and commander skills.
Slot 2: There's really only one choice here for battleships - Damage Control System Modification 1 . This will reduce chances of fire and flood.
Slot 3: Aiming Systems Modification 1

+==In-game historical inaccuracies==
+* 1937 reconstruction is missing. See [[Giulio Cesare]] for the modernized version.
+* High explosive ammunition is missing. The SAP shell is a fabrication by Wargaming.
+* ''Conte di Cavour'' was equipped with only two 40 mm/39 Vickers-Terni 1917 AA guns, located on the forecastle deck. Hull (A) has a whopping eight 40 mm/39 Vickers-Terni 1917 AA guns.
+* The six 76 mm/40 Ansaldo 1917 AA guns were actually located abreast the aft funnel. In World of Warships, however, they are placed atop the superfiring and amidships turrets.
+* All 13 turret-mounted 76.2 mm/50 secondary guns (three on the triple-gun turrets and two on the twin-gun turrets) are missing. These were only removed after her reconstruction.
+* ''Conte di Cavour'' did not receive any 37 mm/54 Breda guns before her reconstruction. Its inclusion on the pre-refit hull and in single mounts (instead of the historical twin mounts) is another fabrication by Wargaming.
