Soviet cruiser Proiekt 22 is mostly known by the public as WoWs Italian tier X large cruiser Napoli. The 22000-ton cruiser with nine 250mm guns was first sketched in about 1936, by Ansaldo.
On this unaccomplished plan replaced by Pr.69 Kronshtadt class several yrs later, WoWs also made Soviet tier XI Novosibirsk and Spanish tier X Castilla. But HOW is Pr.22 and its former designs really look like in history? I feel honoured to be shared with any useful info about this.
As of now, Project 22 remains an enigma. I've yet to find any solid information on this design and its specifications, let alone the blueprints.
All that is known — it was developed in 1935-36 as part of the "Big Navy" programme, and the requirements called for displacement of 19000 to 22000 tons and nine main guns of 254, 283 or 305 mm caliber. Eventually it evolved into Project 69 aka
Kronshtadt-class.
The
Napoli in WoWS is NOT, in fact, Project 22 — it's based on an Italian design, which was ordered from Ansaldo and based on the same requirements as Project 22. The original design had Soviet secondary weapons in form of 130-mm SP and 100-mm DP guns — the Italian 152mm+90mm combo is, obviously, made-up by WG.
Novosibirsk, meanwhile, IS indeed based on Project 22. Or rather, it's WG's interpretation on how it could have looked like if it was laid down in 1930s and finished post-WW2. I doubt WG has found authentic Project 22 blueprints.
As for
Castilla — it has no relation to Project 22 whatsoever. It's an enlarged Spanish Project 138 heavy cruiser (see WoWS'
Almirante Oquendo) with Italian 254mm guns.
First time hearing about this project
But there is info and pictures of it apparently
All those pictures are just speculations or even straight-up alternate history.
And the last two pictures you attached
aren't even related to Project 22. It's a completely different design called
KRL-22 (КРЛ-22, KRL being an acronym for "light cruiser"). It was an early post-WW2 attempt to create a fast, lightly-protected cruiser armed with 220-mm guns, which eventually evolved into Project 66 "meduim" cruiser (
Moskva in WoWS).
