World of Warships Final Review: U.S. Tier IX Freemium Battleship Illinois (2024)

Ladies and Gentlemen, with Update 12.2 is being added a new ship to the Research Bureau. One unlike any other that we have ever seen in the game. The Illinois, U.S. tier IX battleship will become available for 51 000 Research Points.

Is she worth it? Is her one-of-a-kind main battery offering her the firepower to stand strong compared to other battleships? Here is my opinion.

Historical background

At the end of the Second World War, the U.S. Navy found themselves in a bit of a pickle. Out of the six planned Iowa-class battleships, two were still under construction. In 1948, plans were made to convert the USS Kentucky, the most advanced of the two, into an Anti-Aircraft Battleship. For that purpose, the ship’s main armament would be replaced with the same 203 mm guns as the Des Moines-class, keeping the same auto-loading mechanism but in quadruple dual-purpose turrets. This main battery was also meant to be used as anti-air. Don’t ask me why it’s not the case in the game… As far as we know, three designs were proposed with this armament. F with only 2 turrets, G with 3, and H with 4.

When it comes to the secondary battery, it was composed of a whole lot of twin 127 mm/54 batteries with the number varying from one design to the other. Scheme F had twenty of them, Scheme G had sixteen, and Scheme H had fourteen. Due to the extra weight brought by that armament and to clear firing angles as much as possible, the superstructure, especially on Scheme G and H was reduced in size as much as possible. The anti-air would be completed with modern twin 76.2 mm AA mounts with either three of them for Scheme F or six of them for Scheme G and H.

Sadly, none of these designs ever came to be. Other designs would later be proposed to convert Kentucky into a guided missile battleship in the mid-1950s but at the end of the day, both her and Illinois were sold for scrap at the end of the 1950s.

When it comes to Illinois in World of Warships… Let’s just say that Wargaming got incredibly lazy. In the game, it literally is just an Iowa with the main battery turrets swapped for the 203 mm quadruple turrets and the 40 mm Bofors being replaced by 76.2 mm twin mounts. So… yeah, quite a massive disappointment here.

General Characteristics and Playstyle

I might surprise you by saying this but Illinois doesn’t play like a normal battleship. Due to her main armament, she plays a lot more like a big cruiser.

In the first place, the thing isn’t exactly made to tank damage. Between her low HP pool and the limited protection of the Iowa hull, she definitely will not be on frontline duty. Even with her improved Repair Party consumable, any sort of focus fire can fairly easily bring her down. Another thing that makes her vastly different from other battleships is that she doesn’t have the ability to completely nuke an enemy ship out of the water unless you get a particularly blessed RNG on a Smolensk, Minotaur, and such. Instead, she is more of a damage farmer, raining down HE or AP shells on enemy ships.
While this is pretty fun compared to the slow reload of most battleships, this limits the battle influence of Illinois quite a lot. She is reduced to a tankier than normal damage-focused cruiser. Her consumable kit is also extremely basic, she has no Hydroacoustic Search, Surveillance radar, or Main Battery Reload Booster that would help her to influence battle.

That’s really the problem with this ship though. She is a battleship without having the fear factor or tanking capacity of one and at the same time, she is a damage-focused cruiser without that extra something that most of them have.

If you want to see the ship in action, here is a commented replay of one of my games:

The main battery of Illinois is… quite unique among battleships and that’s putting it lightly. Illinois has the smallest gun caliber of all battleships by a large margin as she carries 203 mm guns while the closest is Scharnhorst with 283 mm.

The thing is that these 203 mm guns are the same as those of Des Moines. In fact, the turrets are just a quadruple version of the Des Moines turrets as well. Don’t get your hopes too high though as there are still a few nerfs that were made. The main battery reload time was brought up to 9 seconds compared to the 6 seconds or 5.5 seconds we are used to on Des Moines, Salem, and Annapolis. Also, Illinois is stuck with a battlecruiser dispersion and she only has a 1.8 sigma.

Even with these nerfs, Illinois’s damage output is definitely nothing to ignore and her theoretical DPM isn’t too far behind Des Moines.

Generally speaking, you will be switching between HE and AP shells fairly often as both ammo types are very potent. On one side, you have the very versatile HE which, combined with the volume of fire will start fires easily on your targets, and on the other side, you have the AP with improved penetration angles for reliable damage on most targets that won’t be properly angled. Basically… it’s literally Des Moines/Salem/Annapolis but slightly altered.

They are mostly there for decoration and anti-air.

Anti-air Armament

The anti-air of Illinois is satisfying for a tier IX battleship. The long-range anti-air has solid DPS combined with a strong flak barrage. The medium-range is particularly strong with very great DPS and a higher range than normal thanks to the 76.2 mm AA guns.
The short-range anti-air isn’t anything impressive but then again, this aura is barely useful against dive bombers and that’s about it. The planes don’t spend enough time within it for it to matter.

Number of charges	2
HP per plane	2 000

Sink speed	7.5-11.3 m/s
Explosion radius	375 m
Fire chances	24%

The Armor

The armor of Illinois is almost identical to that of Iowa. This means that in terms of tanking capabilities, she isn’t quite there. One note-worthy part of her armor is the 38 mm casemate that will effectively protect against HE from most cruisers. The only difference, when it comes to the hull, is that the citadel on Illinois is much lower, being fully underwater. This makes Illinois harder to punish when showing broadside.

Other than that, the turrets of Illinois are FAR more fragile than those of Iowa. This is the reason why I heavily recommend Preventive Maintenance as otherwise, you might get frustrating moments where unlucky shell hits cripple your turrets in a heated fight.

Final Opinion

Illinois or rather Kentucky Scheme G and H is something that has been heavily requested by a lot of players. While this is definitely an interesting design offering a unique gameplay among battleships, is it worth the investment?

Well… yesn’t. She is definitely pretty fun to play with her almost Des Moines-ish main battery but you are just uncomfortably sitting with one butt cheek on two different chairs. On one chair, you are like a damage focused cruiser while lacking the flexibility that most have, coming either from their high agility or concealment to get in and out when you wish to and avoid unfavorable trades. On the other chair, you are a battleship size target that lacks the fear factor and nuking ability of its main battery while also having fairly limiting tanking abilities.

Recommended Build

For the Illinois, I recommend the following commander build and upgrades:

If you have access to the commander Halsey, I can recommend using him on this ship.
