Ohio — American special premium Tier X battleship.

A hypothetical armament project for the Montana-class battleship with eight 457 mm guns housed in four turrets. Back in 1938, amid rumors about the creation of ships with guns of a caliber exceeding 406 mm in Japan, there were projects of battleships with 457 mm guns. One of them was relatively fast and had armament comprising six guns in three twin-gun turrets. The twin-gun turrets developed for this project could well have been mounted on one of the unfinished Montana-class battleships.

Ohio, released 16 Sept 2019, is available in the Research Bureau for 62,000.

Ohio would seem similar to Montana, as both share the same hull. However, there are key differences.

Ohio's main battery consists of 8x 457 mm guns, as opposed to Montana's 12x 406 mm guns. While this may seem like an inferior main battery at first glance due to having a smaller salvo weight, Ohio's main battery brings quite a few advantages with it. Ohio's reload time is significantly shorter than that of most Tier X BBs, which partially offsets her low salvo weight. The large caliber means her AP can over-match 30 mm plating found on most Tier X cruisers' midsections, which allows Ohio to be an exceptionally effective cruiser killer. Moreover, her AP has very good penetration, and the main battery's accuracy is impressive - Ohio shares her dispersion pattern and sigma value with Warspite, known for her exceptionally reliable main battery. The subpar ballistics performance can be a double-edged sword - on one hand, leading shots at medium and long range may be trickier than with other BBs, but on the other hand her shells have a steeper impact angle, making the AP arm more often due to it impacting more effective armor, especially when over-matching cruiser plating and BB superstructures. Her HE shells aren't worth mentioning outside of marginal situations, when there are no better targets to shoot than stubbornly angled BBs. And if this wasn't already good enough, her main battery can be further enhanced by a choice of Main Battery Modification 3 or Artillery Plotting Room Modification 2 .

At first glance Ohio's survivability should be no different to Montana's with nearly the same HP pool and armor layout. The key difference is her Repair Party consumable. Montana's variant heals 0.66% total HP/sec; Ohio's variant heals only 0.5% HP/sec (same as most other battleships). However, Ohio's Repair Party cools down in an astonishing 40 seconds, roughly half that of Montana. This makes Ohio extremely resilient to concentrated fire, thus making her adept at both standard tanking as well as tanking when pushing. Her effective survivability rivals the likes of Großer Kurfürst and Kremlin. In addition, her citadel is moderately well protected against BB fire due to it sitting low in the water, and her 38 mm midsection hull plating is decently resilient to HE and SAP fire.

The secondary battery shares much in common with those found on Georgia and Massachusetts — it has good range and very good accuracy, making a secondary build a viable option. In fact, the potent secondary armament and the rapid Repair Party cooldown makes Ohio a potent close range BB, on par with Großer Kurfürst.

Her AA armament is quite formidable for a Tier X BB, but it still won't prevent enemy carriers from getting a strike off on a lone Ohio, even though it may contribute to long-term plane losses.

With regards to her maneuverability, it is worth mentioning that she boasts a significantly faster rudder shift time than Montana with a lower top speed, but is otherwise unimpressive by Tier X BB standards.

Her concealment is also pretty average among Tier X battleships, unless one decided to forego the Concealment Expert skill in favor of building into the ship's secondary armament.

Ohio is best played in a manner similar to Montana. Most of the time, her captain will want to sit around medium range, tank damage, and provide fire support with her main guns. However, when a push from either side happens, Ohio can exploit it very well, either by overwhelming enemies with the combination of her main battery power, her secondary battery's contribution, and her almost unparalleled durability, or effectively stalling a push with the help of the above mentioned characteristics. But unlike with, for example, Großer Kurfürst, one has to be extra wary of enemy destroyers sending torps her way, as Ohio doesn't get access to the Hydroacoustic Search  consumable.

With regards to competitive potential, Ohio is among the strongest BB picks as long as the given competitive format doesn't include aircraft carriers.

Pros:

Well-armored midsection; Ohio is quite durable when properly angled
Quick main battery turret traverse
Good main battery rate of fire
Good main battery accuracy with the Artillery Plotting Room Modification 2 equipped
Excellent secondary armament accuracy, range, rate of fire and fire chance
Powerful AA defenses, like most other USN battleships
Improved Repair Party  consumable with a standard cooldown of only 40 seconds

Cons:

Fairly short main battery range
Slower than Montana by two knots, and only half a knot faster than Yamato
Enormous citadel that slightly rises above the waterline and has a very thin roof. Flashing Ohio's broadside is quite dangerous
An extremely long ship, with a very large turn radius
Poor concealment

Research

As a premium ship, Ohio has no module upgrades to research.

Optimal Configuration

Ohio can benefit from a standard "tank" build that most battleships benefit from, but a better way to build her is to take advantage of her secondary armament in some way. There are two ways to achieve this, depending on whether her captain likes having more emphasis on survival or her secondary battery.

Your first skills should be Priority Target, Adrenaline Rush and Superintendent in both variations. If you want a survivability-focused build, you should spec into Concealment Expert, Fire Prevention and Advanced Firing Training skills, in this particular order. If you're feeling like you're not squeezing enough value out of your secondary armament, proceed with Fire Prevention, Advanced Firing Training and Manual Fire Control for Secondary Armament skills. The last remaining point should go to Preventive Maintenance, considering you will want to pick the Auxiliary Armaments Modification 1 upgrade in slot 1 in order for your secondaries to be effective for as long as possible.

Upgrades

The recommended upgrades for Ohio are as follows:

Slot 1: Auxiliary Armaments Modification 1
Slot 2: Damage Control System Modification 1 
Slot 3: Secondary Battery Modification 1
Slot 4: Damage Control System Modification 2
Slot 5: Concealment System Modification 1 
Slot 6: Artillery Plotting Room Modification 2

The upgrade choice in slot 6 is up to whether you prefer to shoot more often, or if you prefer to be rewarded for good aim.
