History

Unlike the other signatories of the Washington Naval Treaty, Italy was allowed to continue constructing battleships, albeit restricted in their tonnage by a total of 70,000 tonnage for new capital ships. When Italy began the development of the Littorio-class battleships in the 1930s, they knew it would take a while to build them and as a stopgap, they gave an extensive refit of their World War I-era dreadnoughts. Among the changes was boring out and relining their main battery guns. As the Regio Marina (Royal Italian Navy) used two different forms of 12-inch guns on their dreadnoughts from different manufacturers, the new 12.6-inch guns were given different designations for the refits on their dreadnoughts. For the Andrea Doria-class dreadnoughts, the guns were redesignated the 320 mm/44 Ansaldo model 1936.

The Ansaldo model 1936 guns began life as the 305 mm/46 Vickers model 1909 on the RN Andrea Doria and her sister ship the RN Duilio. The new Ansaldo-modified guns were bored out (which included moving the A tube and wiring) to 320 millimeters from 305 millimeters. The other changes were the addition of new liners, new ammunition, and increased elevation angles. During World War II, the Andrea Doria and Duilio saw little action in combat as the lack of radar or aerial reconnaissance left their battleships only rarely able to locate and attack British targets. The two ships spent most of their career during the war engaging in convoy escort duties in the Mediterranean. The rare case of the Andrea Doria seeing action occurred at the First Battle of Sirte on December 17^th, 1941, off the coast of Libya and possibly damaged the destroyer HMS Kipling (British sources note the caliber of the shell splinters were the same as the main battery guns of the Andrea Doria or Giulio Cesare). Eventually, both ships were forced back into port before the Armistice with the Allies in September 1943 (the Andrea Doria due to mechanical faults and the Duilio due to Italy’s fuel shortage) and were scrapped in 1956 and 1957 respectively.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.

-The '''320 mm/44 Ansaldo model 1936''' is an Italian 320 mm naval cannon. It is a competent, high-penetration, high-velocity gun with a relatively small explosive filler.
-Guns were created as a part of the interwar refit of the Andrea Doria-class, being a bored-out [[305 mm/46 Vickers model 1909 (305 mm)|305 mm/46 Vickers]] with a number of other upgrades such as a welded-on armor plates.

-Being a bored-out version of the [[305 mm/46 Vickers model 1909 (305 mm)|305 mm/46 Vickers model 1909]] the gun features an unusual calibre and some atypical characteristics of the weapons of this size. It makes a difficult compromise, trading explosive filler for penetration, which makes it particularly problematic to deal with a more bulky targets. This is not helped by the lack of HE rounds. What creates further problems for this gun are its turrets - having 240 mm near-flat turret face, and 110 - 170 mm welded on top of the 120 - 180 mm barbette armor makes it easy to penetrate by most of the BR 7.0 and some of the BR 6.7. Added armor offers less protection than a single solid plate.

+''Describe the shells that are available for the weapon and their features and purpose. If it concerns autocannons or machine guns, write about different ammo belts and what is inside (which types of shells).''
-Gun features only two types of shells:
-* 320 mm Granata Perforante - Semi-Armor Piercing (SAP) - When possible they are the preferred choice, as they have 360% more explosive filler than the armor-piercing shells, thus they should be the first choice for a vast majority of the heavy cruisers and everything smaller.
-* 320 mm APHEBC Palla - Armor-Piercing Capped Ballistic Capped (APCBC) - Dedicated shell against heavy armor with both: armour-piercing cap and ballistic cap, which effectively translates to a better penetration at a higher angles of attack and longer ranges. It's best used against battleships and battlecruisers - while the post-penetration effect is miserable, it still can surprise even much more capable enemies. It's best used to destroy enemy [[ammo racks]], where the amount of explosive filler isn't important if the magazines are hit directly.

-{{Notice
- |There are no direct 320 mm / 12.5-inch equivalents in foreign nations. Representative rounds between 305 and 356 mm are used for comparison instead.

-Compared to its peers ammunition of the 320 mm/44 Ansaldo model 1936 features a consistent trade-off, prioritizing armor penetration over the mass of the explosive filler, a characteristic shared by both its available round types. It's particularly evident the case of the armor-piercing rounds: explosive filler is the smallest one among comparable guns, it's smaller than even the German 283 mm guns, while having penetration values that can be matched only by a higher calibre shells.
-Other two features worth noting is an exceptional targetting speed, allowing the guns to swiftly shift their aim from target to target, and a slightly above average muzzle velocity, which allows shells to sustain a good penetration at range and makes round trajectory somewhat flatter, an aspect that can be advantageous or disadvantageous depending on the specific target and combat context.
