Cristoforo Colombo — Italian Tier X battleship.

A hypothetical project that is a variant of the development of Italian ships based on the Vittorio Veneto class and a battleship project for the U.S.S.R. with a displacement of 42,000 tons. The increase in firepower could have been achieved by increasing the number of guns and turrets: quadruple-gun turrets with 381 mm guns were in development in the late 1910s and early 1920s.

Performance

As the Tier X battleship, Cristoforo Colombo is the culmination of the Italian battleship line. Similar to Montana, Cristoforo Colombo gains an extra turret over her Tier IX predecessor, Lepanto. As a result, her main strength lies in her sixteen (16) 15-inch main battery guns. However, she has an extremely low base range for a Tier X battleship at 18.91 kilometers - nearly two kilometers shorter than Grosser Kurfurst 20.6 kilometer range. Therefore, she excels at punishing broadside targets at close to medium range, but lacks the ability to trade at range with her peers. Overall, captains will find Cristoforo Colombo’s adept playstyle to be incredibly unique.

Cristoforo Colombo’s defining characteristic is her extensive main battery suite. With sixteen (16) 15-inch main battery guns, Cristoforo Colombo currently holds the title to the highest broadside weight in the game, marginally beating out Vermont’s twelve (12) 18-inch main gun battery. Like her predecessors, she has unique access to semi-armor piercing shells in place of high explosive. As a tradeoff, her standard armor-piercing ammunition has very low penetration in comparison to her peers. Despite this, her armor-piercing shells are more than enough to deal significant damage to broadside cruisers and deal substantial damage to battleships and destroyers alike due to the sheer volume of fire. In addition, she has a -30% shell swapping bonus built into her, like the rest of the line.

However, Cristoforo Colombo’s main battery falls short in its ability to overmatch more than 26mm of armor with AP shells, being only 15 inches in diameter. As a result, Cristoforo Colombo encounters situations where she is unable to deal significant damage with AP to some Tier X cruisers when angled properly. However, this downside is partially alleviated due to the fact that Cristoforo Colombo has access to SAP, allowing her to still reliably deal damage to all Tier X cruisers unless they are perfectly angled. Additionally, her guns are relatively imprecise; the main battery has the standard battleship dispersion formula and only 1.5 sigma.

At a max speed of 29.6 knots and a base rudder shift time of 18 seconds, Cristoforo Colombo’s maneuverability is about average for a Tier X battleship. However, she also gains access to the special Exhaust Smoke Generator  consumable, allowing her to create smoke cover that can keep pace with her even at max speed for a base duration of 45 seconds. As a result, Cristoforo Colombo is able to turn out from imminent danger so long as captains are careful not to fire her main battery, as she is detected from 16.7 kilometers while firing in smoke. In addition, despite having only 89,900 hit points, Cristoforo Colombo can shrug off much damage owing to a fantastic armor scheme. With a 70mm upper belt and fully submerged citadel compartment, she is incredibly difficult to punish even when broadside and mitigates a significant amount of incoming damage when properly angled to the enemy.

As a whole, Cristoforo Colombo captains will find her flexible gameplay very enjoyable. Playing optimally, captains will have to switch between SAP and AP to whittle down targets with SAP and punish broadside cruisers and battleships with AP. Overall, the ship is very forgiving due to its excellent armor scheme and access to Exhaust Smoke Generator .

Pros:

• Largest number of main guns of all Tier 10 battleships, with sixteen (16) rifles
• Currently the heaviest AP broadside in the game, slightly heavier than Vermont's
• SAP shells can be extremely effective against angled and/or lightly armored targets
• Built-in -30% shell swap time.
• Good main battery firing arcs
• Both aft turrets can turn 360 degrees
• Both SAP and AP shells have very good shell velocity and low air drag
• Good midsection external armor, useful to counter HE shells
• Fairly powerful AA defenses
• Access to the Exhaust Smoke Generator  consumable
• Fairly good ship speed of 29.6 knots

Cons:

• Third smallest hitpoint pool among Tier 10 battleships
• Main guns have no access to HE shells
• Second worst reload speed in its tier/class, only Vermont's is longer
• Very poor accuracy, comparable to Tier 7 French battleship Lyon
• Small gun caliber, AP shells cannot overmatch 27mm armor
• Shortest main battery range of all Tier 10 battleships
• Virtually useless turtleback, can be overmatched by all AP shells of 380mm and larger calibers
• Enormous target with poor concealment
• AA defenses are short-ranged, making them rather ineffective at preventing plane strikes
• Most secondary mounts are 90mm and lack penetration (even with IFHE)
• Very large turn radius and fairly slow rudder shift
