Ship:Cristoforo Colombo

20,700,000

Cristoforo Colombo — Italy Tech Tree 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.

Pros

• Great damage per salvo
• Exhaust Smoke Generator consumable available
• Allows the ship to remain undetected, even while traveling at full speed.
• Quick shell type switching time

Cons

• Small HP pool
• Short firing range
• Low firing accuracy

• Sigma parameter reduced from 1.6 to 1.5.
• Deck armor reduced from 55 to 50 mm.
• Secondary battery accuracy decreased to standard battleship values.
• SAP shell damage decreased from 14,050 to 12,500.
• Action time of the Damage Control Party consumable increased from 10 to 15 s.
• Main armor belt thickness decreased from 400 to 375 mm.
• Citadel roof armor thickness decreased from 40 to 25 mm.
• Citadel upper angled armor decreased from 40 to 25 mm.
• Citadel torpedo bulkhead armor thickness decreased from 70 to 50 mm.

• View range increased from 26.4 km to 29.4 km.
• Update 0.9.10:
  • Available for testing by supertesters in the game starting from Update 0.9.10.
• Update 0.10.3:
  • Introduced into the game as a researchable ship in Update 0.10.3
• Update 0.10.5:
  • Main battery reload time decreased from 38 to 37 s.
  • Main battery 180-degree turret traverse time decreased from 40 to 38.2 s.
• Update 0.11.5:

• Update 0.11.8:
  • Added a separate 30% bonus to the shell-type switching time, applied even when the Gun Feeder skill is inactive.
• Update 12.5:
  • The Smoke Generator Modification 1 upgrade can now be mounted in slot 3.
• Update 12.8:
  • Fixed textures for the ship.
• Update 12.11:
  • Fixed an issue that caused the armor of the ship not to correspond to the set parameters: deck slope armor thickness – 25 mm; citadel armored deck slope armor thickness – 25 mm.

  • Sigma value increased from 1.5 to 1.6.
  • Firing angles for the aft turrets increased by 10 degrees.

    • Spotting Aircraft consumable removed.
    • Dispersion pattern changed. The point at which accuracy begins to degrade moved closer to the ship.
    • Access to Gun Fire Control System Modification 2 removed.
