Supertest: U.S. Tier X Freemium Battleship Ohio

The Update 0.8.6. seems to mark a bit of a break in terms of new ships entering supertest. This month, only one ship is being introduced and it’s the tier X Freemium Battleship Ohio.

This battleship is with the Colbert the first reward ship of the upcoming Naval Training Center so don’t expect her to be released any time soon. As for the ship itself, the Ohio is based on the never-built Montana-class of the U.S. Navy, more specifically BB-67-4 design.

The Montana-class was the result of the late 1930s “slow” battleship design that would, compared to the Iowa, be more heavily armored in exchange for a top speed of 28 knots. The main battery armament of the class varied at the start from 356 mm guns (14-inch) to 457 mm guns (18-inch). In the end, it was decided to use an armament of 406 mm guns with the final configuration being 4 triple turrets with 2 superfiring at the front and 2 superfiring aft.

Compared to previous designs, the Montana-class was built without taking into account the beam length restriction imposed by the Panama Canal. Also, with the different Naval Treaties being happily abandoned by foreign countries, the U.S. Navy dropped the 45 000 tons displacement limit to allow the ships to boast both better firepower than the Iowa and much better armor protection. At this point, the different designs proposals were varying from 51 000 to 80 000 tons but the armament was maintained.

It will only be in 1941 that the number of options was narrowed to 4 with only a few details changing from one design to another. The Montana-class as it would have most likely been built would have carried 4 triple turrets with 406 mm/50 guns, 10 twin turrets with 127mm/54 guns and a variety of 40 mm Bofors mounts as well as 20 mm Oerlikons. As for the speed, the Montana-class would have been able to achieve 28 knots. The main belt was planned to be 409 mm thick and placed on the outside of the ship compared to the internal main belt of the Iowa-class. The standard displacement would have reached 64 00 tons with a maximum displacement of over 72 000 tons.

The 5 ships initially ordered were supposed to be named Montana (BB-67), Ohio (BB-68), Maine (BB-69), New Hampshire (BB-70) and Louisiana (BB-71). However, in the end, no ship was ever built due to the steel shortage (because yes, even the U.S. industrial power had its limits). Funnily enough, Montana remains the only U.S. state without a completed battleship bearing its name.

If you want to know a bit more about the Montana-class, I recommend to you this video from Drachinifel:

When it comes to World of Warships, Ohio is basically a what-if scenario where the U.S. Navy would have changed their mind on the main battery of the Montana-class, bringing back the twin 457 mm gun turrets that were initially abandoned. On top of that, she boasts a late war anti-air armament, carrying the 76.2 mm twin AA mounts.

She also boasts the same dispersion as the Georgia which follows the large cruiser dispersion pattern.

The armor


Without much of a surprise, the Ohio has the same armor as the Montana, may it be the bow, the stern or the middle section, everything is the same except for the turrets.

The bow section


The bow’s external plating is the classic 32 mm, nothing to see here.

When it comes to the protection of the middle section, the upper casemate is 25 mm thick but then it thickens to 457 mm. As you can see, the upper part of the citadel’s athwartship is also 457 mm thick.



As for the lower part of the citadel’s athwartship and the casemates around it, they are 432 mm thick.

The middle section


For the middle section, the weather deck and the sides of the ship are 38 mm thick. As for the main belt, it is 409 mm thick for the biggest part but it then tapers to 259 mm.

As for the citadel’s side protection that is behind the torpedo bulge, it is first 180 mm thick and then the lowest part is 110 mm thick.

When it comes to the horizontal protection, the Ohio, just like the Montana is well protected against AP bombs with a 150 mm main armor deck and a 19 mm splinter deck (the citadel’s roof). This will block AP bombs from reaching her citadel in general.

The stern section


On the outside, we have the classic 32 mm plating, nothing special.

Inside the stern, there are 2 armored decks. the first one is 178 mm thick and covers a large part of the citadel’s athwartship. The second one is 6 mm thick only and will pretty much never ever be useful.


For the protection of the middle section, there is first a 25 mm casemate.

Just under it, there is a 387 mm plating, including the upper part of the citadel’s athwartship. Finally, the lower part of the citadel’s athwartship and the casemates around it are 324 mm thick.

The superstructure


The superstructure’s plating is the classic 19 mm that you can find on all high tier battleships. On top of that, the secondaries have a 64 mm plating just like those of the Montana, making them well protected against HE shells.

The turrets


The turrets are the same as on the Georgia. The face is 540 mm thick, the sides are first 305 mm thick and then 241 mm thick. The back is 360 mm thick and the roof is 184 mm thick. Overall, nice protection for sure.
The barbette is divided in 2 with the upper part being 541 mm thick and the lower part is 51 mm thick.

Personal opinion

I’m seriously hyped for the Ohio. I loved the guns of the Georgia so a ship with the same guns, same dispersion and an additional turret, that’s a big yes for me. On top of that, the AA is amazing, she has the fast cooldown on the repair party, I really can’t wait to test her.

As for how much grind will be needed with the Naval Training Center, that is a big mystery.

  1. With such guns, better armor and speed one has to wonder whats the point of the Yamato now, especially if this monster fires once every 25 seconds.

  2. Ah, the American Thunderer. Looks promising, eight Georgia guns on a Montana hull will not be something to be trifled with… I wonder if the actual Thunderer (and the Slava/Pobeda) will also end up being Freemium ships…
