World of Warships Final Review: Japanese Tier IX Premium Battleship Iwami
Ladies and Gentlemen, today we will talk about Iwami, the new tier IX premium Japanese battleship. The ship will become available starting from the 8th for 19 300 doubloons or 228 000 coal in the armory. Alternatively, she will be available in the premium shop with the standard bundle costing 63.49€.
Is she worth it? Are we getting the first Japanese battleship made for brawling? Here is my opinion on the subject.
Historical background
Iwami is based on two of the preliminary A-140 designs that lead to the Yamato-class battleships. She gets the general armament layout and hull design of the A-140-J3 with four main battery turrets in AB-XY configuration for the main battery and then three triple 155 mm secondary turrets around the Y turret. However, she gets the main armament of the B2 variant with four twin turrets.
Now on that table, the main battery caliber is 40 cm (400 mm) but it’s how Japan was calling the 460 mm guns. Iwami on the other end is armed with 410 mm guns. The ship also gets a Kii-like refit with two quadruple torpedo launchers at the rear as well as many twin 100 mm secondaries.

The camouflages
The permanent camouflage of the Iwami provides the classic bonuses for tier IX ships:
- -3% to surface detectability range
- +4% to maximum dispersion of shells fired by the enemy at your ship
- -20% to the cost of ship’s post-battle service
- +100% to experience earned in the battle
The Good and the Bad

The Iwami is suffering from a serious identity crisis. She isn’t a good Japanese battleship and neither is she a good brawling ship, making her sit in a particularly uncomfortable spot.
When it comes to her classic Japanese battleship side, she really doesn’t bring much to the table. Her only two strengths are the great firing angles and the 2.1 sigma. Other than that, she is stuck with only eight guns and a reload that is only a little bit below average. The AP penetration is far worse than what you would find on Izumo and is outclassed by the other 16-inchers at medium range and beyond. She also lacks a spotter plane to bring any sort of real crossfire potential from across the map while Izumo has no issue with that and the same goes for Hizen.
For the brawling part, she lacks many things to make her anywhere near viable in that role. Outside of the high HP pool and 50 mm deck, she is really easy to farm with the 32 mm armor and large superstructure. She is also far from being particularly mobile with a maximum base speed of only 28.2 knots. This means that if things get hot, she can’t disengage fast. Her secondaries are also nothing spectacular. Not enough guns, lack of range, not enough damage output, and also too squishy to provide any meaningful damage source. Obviously, the torpedoes are here to help but you can only use them at the last moment if you don’t want to get punished due to the firing angles.
There is no commented replay this time because I’m too short on time lately.

The main battery of Iwami is quite underwhelming. From the start, she only gets eight guns compared to nine or twelve for the other Japanese battleships at tier IX. On top of that, the AP penetration is one of the weakest at tier IX, quickly falling behind all the other 16-inchers may it be Iowa, Sovetsky Soyuz, or Friedrich der Grosse at medium range.
In return for the limited number of guns, the ship gets a 2.1 sigma but then again, you still suffer from poor vertical dispersion. Get ready to see shells falling too high or too low fairly often.
As a bit of saving grace, she gets great firing angles to limit the amount of broadside needed to bring all guns in action but that’s about it.

The secondaries of Iwami are not nearly as strong as they should be to make her a viable brawler. To begin with, she only gets a base range of 6.95 km which is the lowest you can have on tier IX battleships. She also has a fairly weak broadside with only two triple 155 mm turrets that suffer from long reload and four twin 100 mm turrets that are fairly fragile. Another thing that further weakens the number of secondaries you can bring on target is the poor firing angles of one of the 155 mm turrets that forces you to give a lot of broadside to use it.
One good thing is that these secondaries get the same dispersion as those of the German battlecruiser line. Still, once again, with the weak broadside and low range, you really won’t achieve much since, with the combined poor range and low speed of the ship as well as her underwhelming armor protection, she will just take a lot of damage while trying to close the distance. Also, if you wanted the secondaries to be effective against battleships, you would need IFHE. The problem is that you don’t really have points to spare for them unless you drop Grease the gears but even then, with the low range and weak broadside, it’s honestly not worth it.

One of the gimmicks of Iwami is that she gets one quadruple torpedo launcher on each side. Initially, it was 12 km torpedoes which were very useful when kiting as they had fairly good spotting range and were working well in relation to the surface spotting range of the ship.
Now, she gets 20 km torpedoes with lower damage, worse spotting range and as a whole, much less utility except against dumdums not paying attention.

While Iwami gets strong long-range anti-air, she is stuck like most Japanese ships with 25 mm AA guns as the next aura. The weak DPS, as well as low firing range on these, leads to them generating a weak aura, and overall, the anti-air on Iwami turns out to be unimpressive.

Final Opinion
Honestly, I just can’t recommend the Iwami, even if you missed Hizen and Musashi. She isn’t absolutely worthless but compared to most tier IX battleships, she just doesn’t stack well. She suffers from a massive identity crisis, failing to be a good standard Japanese battleship because of the lack of punch of her main battery compared to other battleships at medium and long-range. At the same time, she also fails to be a brawling ship because of her lack of survivability, and underwhelming secondary battery. If it wasn’t enough, Japanese battleships actually have the worst dispersion at close range so that doesn’t help either.
If you want a Japanese battleship captain trainer, you have Hyuuga, Ashitaka, or even Kii. If you just want a strong Japanese tier IX battleship and don’t have Musashi, just get Izumo. If you want a brawling ship with strong secondaries, grind the German battlecruiser line. The Iwami… she is nothing more than a coal or doubloons sink. Even in that regard, there is still a long list of ships available for coal that are just better.
