Battle Levels

Colorado — American Tier VII battleship.

The ship design is based on the Tennessee class but equipped with 406 mm/45-caliber twin-gun mounts. Upon entering service, USS Colorado was assigned to the battle fleet stationed on the West Coast of the United States. Colorado was stationed at Pearl Harbor from 1941; however, at the time when the surprise attack of December 7 took place, the battleship was undergoing an overhaul at Bremerton. The ship provided support for the assault landing on Tarawa, pre-invasion shelling and fire support for the invasions of Kwajalein and Eniwetok, and assisted the landings in the Philippines and Okinawa.

Player Opinion


The very pinnacle of the American dreadnought and one of the Big Seven, Colorado is the last ship of this type you will experience within the US battleship line. While retaining the sluggish nature of the previous ships in the line, she has increased range and hitting power thanks to her 16in guns, as well as strong anti-aircraft armament.

A massive departure of the other American super dreadnoughts New York, New Mexico, and Arizona, Colorado, behaves more like a close-in brawler, slowly closing the gap with other battleships, under the protection of her thick armor and sound torpedo bulge. However, her atrocious acceleration, low speed, and relatively low hit points require exceptional situational awareness, careful positioning, good damage control management, and constant movement (she should never slow to a full-stop). Furthermore, without a range modification installed, she must focus on closing distances with enemy cruisers and battleships to 14km or less, where her excellent guns are most effective at smashing them to bits.

Recently, her WWI-era hull was removed, greatly aiding in the leveling-grind and boosting her range to the point where installing the Artillery Plotting Room upgrade will depend on one's play-style. Fitting her with the latter will boost her range to rival her contemporary, Nagato, but doing so will exclude maximizing either her secondary weapon or AA focused-build options. Colorado also received a buff to her hit points, putting her on par with her contemporaries at tier 7.


  • All-or-nothing armor: she has the same solid 343mm (13.5 inch) thick all-or-nothing armor layout as New Mexico, being easy to angle and providing a large immune zone
  • Good gun characteristics: she has good damage and penetration on guns including over-matching all 25mm battleship hull armor, as well as a reasonably tight shell grouping, also reloads 4 seconds faster than New Mexico.
  • Powerful AA guns: modernized hull's AA suite will shred mid-tier squadrons, making Colorado an unappealing casual target or flyover
  • Has good steering response times and tight turning radius
  • Equipping the Artillery Plotting Room modification upgrade can reduce the range gap with her Japanese and German tier counterparts
  • Fighter seaplane is available to replace spotting planes to enhance AA defense
  • Main battery's tight spread means it can severely damage, if not outright destroy, any ship at close range effectively
  • Repair Party heals 0.65% of maximum hit points per second, compared to the standard 0.5% hit points per second, partially compensating for the lower health pool.


  • Very low mobility: Feels even more sluggish compared to the New Mexico, also has atrocious acceleration without top engine, thus it is also very hard to stop and reverse while sailing her. (In fact, she has less horsepower than even New Mexico)
  • Low number of guns: having four fewer guns than her predecessor, being accurate in making your shots is much more important.
  • Guns can suffer from inconsistent dispersion both beyond 14 km and within 6 km.
  • Poor close-quarters defense: her secondary armament pales in comparison to Nagato and Gneisenau
  • like most tier 7s she has 26mm plating everywhere vulnerable to HE spam and overmatch by 15in guns or bigger.
  • Fat superstructure is especially prone to HE spam and getting set on fire.


Colorado is very slow. Therefore, researching the Engine upgrade is highly recommended. Afterwards, one should research Colorado (B) before the Gun Control Fire System upgrade, as any range increase provided by the latter is offset by the ship's lack of main gun accuracy at longer ranges. Additionally, Colorado (B) greatly increases ship stamina and AA defense, two assets Colorado must rely upon to compensate for other deficiencies. Researching the B hull unlocks progression to North Carolina.

Beginning from Update 0.9.11, the US battleship line splits into fast (North Carolina/Iowa/Montana) and slow (Kansas/Minnesota/Vermont) lines, with Colorado as the split point. USS Kansas and the ships which follow her are an extension of the Colorado's design philosophy, trading speed for armament, and Kansas is researched directly from the Colorado's main gun module. These are more difficult ships to play than North Carolina/Iowa/Montana, and inexperienced players might best be advised to unlock North Carolina first then spend further time in Colorado to ascertain whether the "slow line" design philosophy truly suits them before progressing to Kansas.

Optimal Configuration


Despite her shortcomings, Colorado is a surprisingly modular ship which can be tailored to focus on main guns, secondaries, or AA.

Slot 1 is most commonly filled with Main Armaments Modification 1 -20% to the risk of main battery becoming incapacitated. / +50% to main battery survivability. / -20% to main battery repair time. / -20% to the risk of torpedo tubes becoming incapacitated. / +50% to torpedo tubes survivability. / -20% to torpedo tubes repair time., though Auxiliary Armaments Modification 1 : +100% survivability to each. is a popular pick for captains who go for a full AA build with other upgrades and commander skills.

Slot 2 has one choice for battleships - Damage Control System Modification 1: -5% to the risk of fire. / -3% to the risk of flooding when torpedoes hit the torpedo protection.. This will reduce chances of fire and flood.

Slot 3 offers several options. AA Guns Modification 1 +20% reduction in the preparation time of the priority AA sector. will boost the outer AA envelope, while Secondary Battery Modification 1 : +20% secondary battery firing range. / -20% secondary battery dispersion. will boost the range and accuracy of secondaries instead. Artillery Plotting Room Modification 1 Extends the firing range of the main battery and secondary battery: +16% main battery firing range. / +5% secondary battery firing range. / -5% secondary battery dispersion. will increase range and give secondaries a slight boost in range and accuracy, but may be a weaker choice than the other two.

Slot 4 Steering Gears Modification 1 : -20% rudder shift time. is recommended and will reduce rudder shift time. Captains with fire problems could also consider Damage Control System Modification 2 : -15% flooding recovery time. / -15% fire duration., reducing the amount of time on fire and conserving hit points.

Commander Skills


Colorado is equipped with the following consumables: Damage Control PartyWhen activated, instantly repairs fires, floods, and incapacitations, and prevents more for the duration., Repair PartyWhile active, restores a percentage of the ship's health points each second., and a choice between Spotting AircraftWhile active, a spotter plane circles the ship enhancing main battery firing range. or Catapult FighterWhile active, a group of fighter planes circles the ship providing protection by attacking incoming enemy aircraft.. Given Colorado’s limited range, prioritizing the Spotting AircraftWhile active, a spotter plane circles the ship enhancing main battery firing range. over the Catapult FighterWhile active, a group of fighter planes circles the ship providing protection by attacking incoming enemy aircraft. will often give more benefit.


Note: Use of the Juliet Charlie signal makes detonation impossible.
