The R-10 is based on the hull of the Tashkent but presents a few differences. I don’t know if it is based on any sort of real design from the Soviet Navy but according to the people I asked to, it isn’t.
When it comes to the differences, the R-10 is using the BL-109A turrets which are a late/post-war design. Her gun performances are the exact same as on the Grozovoi, except for the range and reload. The ship also has an armor scheme similar to the Khabarovsk BUT, unlike her, she is protected against full penetrations from large-caliber AP shells!
She also has better torpedoes that Tashkent as these are the same as on the upgraded Udaloi.
In the end, in action, we are getting a Khabarovsk with one less turret but in exchange for a lot of advantages such as usable torpedoes or better agility with the cherry on top being the protection to full damage from large-caliber AP shells.
There are a few things that aren’t clear about this ship yet. In the devblog that announced her, Wargaming said that she has a higher firing range and turret traverse speed than Tashkent but unless they are talking about the A-hull Tashkent, it’s not the case at all since the turret traverse is the same as on the Tashkent with upgraded guns.
I don’t know if it was forgotten, if they mixed things up with the stock Tashkent or if the idea was dropped but as of today, in the game files, it’s the way the ship is.
For the classic reminder, this is a ship in testing, anything can change so don’t look at her like she would already be released.
As explained at the beginning, the R-10 presents the same kind of armor protection as the Khabarovsk.
The bow and stern are protected by the classic 19 mm of armor. For the middle section, the deck is 25 mm thick, giving her a bit of protection against enemy destroyers and will also allow her to bounce AP shells of a caliber of 354 mm or smaller. On the sides, she has a uniform 50 mm belt giving her a very nice protection against most AP and HE shells.
For the superstructure, the most part is 13 mm thick except the conning tower with 20 mm of armor.
Finally, the turrets are protected by 12 mm of armor.
We are basically getting a better Khabarovsk right here. Yes, compared to her, you lose a turret but there is so much benefit in return (actually usable torpedoes, better concealment, better agility, smaller target, etc.) that in my opinion, it’s just a better ship.
