Supertest: Russian Tier VI battleship Izmail

Moving on in that upcoming battleship branch, here is the tier VI, the Izmail (finally a name I could pronounce without the fear to butcher it).

Alright, background time. We are, again, looking at a battlecruiser design. These battlecruisers were designed to counter the growing Turkish threat in the Black Sea.
Four ships were laid down in 1913 but none of them was completed due to the collapse of Russia in 1917. After World War 1, multiple ideas to complete the ships were considered but in the end, all were abandoned and the ships were all scrapped.

I will cover both the stock configuration and the fully researched configuration for the tech tree ships.

Additional note: Wargaming freshly released a devblog article about the Russian battleships so I will use the new values in the said article. Looks like it was somewhat of a good thing that I was too busy to release the article sooner.

The armor analysis

general.JPG

Looks like the Russian navy ran out of steel for that ship. Unlike the previous ones that had amazing external armor protection all over the ship, this one is quite a serious let-down.

The bow section

bow1.JPG

Do you remember the impossible to overmatch bows of the low tier battleships? Well, forget them. In the case of the Izmail, it is MUCH more vulnerable. The upper part of the bow is covered in 25 mm which means that battleships with 380 mm guns and higher can overmatch it. For the extended belt, it is starting from the middle section with 181 mm, then 125 mm and finally 113 mm thick.

There are two armored decks in the bow but they might as well not be here. The upper armored deck is only 12 mm thick and the lower one is 20 mm thick. If a shell went through the bow, don’t expect it to be blocked by these two decks.

For the frontal protection of the middle section, the lower part, including the citadel surrounded in red, is 32 mm thick and just above, 75 mm thick. The 75 mm part is at the same level as the extended belt but shells will definitely be able to pass above it and then will have no issue penetrating the citadel’s athwartship. Conclusion, this ship risks to take quite a few citadels through the bow by battleships able to overmatch 25mm.

For the upper casemate, there is first a 25 mm plate right above the 75 mm section and just above, a 100 mm plate.

The middle section

middle.JPG

Well, this ship sure feels odd when comparing to the rest. The main belt (in red) is 300 mm thick which is decent, however, the rest of the middle section is covered with 25 mm of armor with the only exception being the deck under the first turret (36 mm).

mid2.JPG

The upper part of the citadel’s sides that is protected by a spaced armor scheme is 50 mm thick. It is the only part of the citadel coming out of the water with the deck so, just like the previous ships, be careful when giving broadside.
The sloped armor of the turtleback protecting the lower part of the citadel is also 50 mm thick.

Here is however a BIG problem…

mid3.JPG

The citadel’s deck is ONLY 20 mm thick. This is really, really bad. any battleship that can overmatch the 25 mm casemate or simply penetrate it will score citadels on this ship. I really hope that they will change this otherwise, I will really use some free XP to skip it. Even worse, a battleship able to overmatch 20 mm just need to penetrate the 25 mm casemate and will also land citadels.

mid4.JPG

The only exception to the problem I described above is under the 1st and 4th turret where the citadel’s deck is 40 mm thick.

mid5.JPG

Finally, for the lower part of the citadel, it’s 32 mm thick.

The Stern section

stern1.JPG

The stern is somewhat of a saving grace compared to the disappointment that was the rest of the armor. It is protected by 25 mm of armor with the exception of the extended belt that is 181 mm thick at first and then 125 mm thick. Keep in mind that this extended belt is underwater.

There are not 2 but 3 armored decks inside the stern. The highest one is 50 mm thick and is at the same level as the citadel’s deck. The 2 others are only 20 mm thick sadly so they won’t be of much use.

For the rear protection of the middle section, there is at first the citadel’s athwartship surrounded in red with 32 mm of armor then it thickens to 75 mm just above. However, the highest part of the citadel’s athwartship is only covered by 25 mm of armor. Considering this part is only really protected by the armored deck of 50 mm, we can safely say that it will be relatively easy to hit it.

stern7.JPG

Finally, just above, there is a 100 mm thick casemate that will somewhat protect the incredibly vulnerable citadel deck from shells penetrating the stern.

stern6.JPG

The superstructure

superstructure.JPG

The superstructure is rather small so the destroyers won’t have that many things to penetrate with HE. It is protected by 16 mm of armor.

The turrets

turret.JPG

For the turrets, the face, the sides and the back are 300mm thick and the roof is 200 mm thick. For the barbette, the top is 248 mm thick and then the lower part is 135 mm thick.

To conclude, this ship is simply fragile. While the lower part of the citadel is well protected, the upper part is so thinly armored (especially that 20 mm deck) that right now, I wouldn’t touch that ship with a 100 m stick. I would be too scared of citadeling it.
