Jodl class Heavy Cruiser
The Jodl class was named after a Rossiyan Commodore from the War of Liberation, Heidi Jodl. She passed away in combat near the Rohtgram Sea between Rossiya and Madagascar. The Jodl class like the Tarina class and Torivok class, were powered by diesel engines and were built by wielding. This saved quite some weight. The Jodl class cruisers were quite fast cruisers for their type at 29 knots. They were also were quite heavily armoured with belt armour at its thickest eleven inches and deck armour that was three and a half inches thick. They were quite heavily armed with a main battery of eight 8 inch guns, four 120 mm anti air guns, twelve 20 mm anti-air guns and 6 533 torpedo tubes. The original order was twenty but it was cut down to just ten and all ten were built

Arachne class Light Cruiser
Thanks to the doctrines learned from the Kriegsmarine, the Arachne class light cruisers were built with the purpose to raid convoys and just wreck them, thus it lacked armour only 6 inches at the thickest on belt armour and just 2 inches of deck armour but it had the speed, 30.7 knots thanks to her diesel engines. Her class also had 20 six inch cannons, eight 610 mm torpedo tubes, eight 100 mm anti-air guns, and thirty six 25 mm anti-air guns so if she or any of her sister ships came across an enemy convoy, she will destroy it with relative ease. Rossiya built twenty five of these speedy cruisers.

25 cruisers just for the purpose of raiding convoys? 10 of the biggest aircraft carriers in the world? while I like some of the designs quite a lot, I am not certain those numbers of specialised designs are actually likely to be had.....

That a very heavy belt and deck for a CA rather than a light BC when are they built as they will never be under 10,000t and treaty compliant. (29 isn't really fast for a CA as well)
This is also slow for a CL

You are building 35 CA/CLs that ok for a major power but it is a lot. (when are they built ? over how many years and pre or during the war ?)
They also have a mix of guns etc that makes resupply annoying (20mm,25mm,100mm,120mm,6',8' and 2 types of torpedo as well ?)

A little querry I have is about your use of fonts, in the last two cruisers each has a different font size. Is it intentional??

Arachne class Light Cruiser
Thanks to the doctrines learned from the Kriegsmarine, the Arachne class light cruisers were built to support fleet action but they have the capability to raid convoys if necessary, thus it lacked armour only 6 inches at the thickest on belt armour and just 2 inches of deck armour but it had the speed, 37 knots thanks to her diesel engines. Her class also had 20 six inch cannons, eight 610 mm torpedo tubes, eight 100 mm anti-air guns, and thirty six 25 mm anti-air guns so if she or any of her sister ships came across an enemy convoy, she will destroy it with relative ease. Rossiya built twenty five of these speedy cruisers.

During the period between 1925 to 1942, Rossiya and Japan had a naval agreement so yeah Rossiya had many of its designs from Japan. But I must point out that there are American, German and British based equipment. Rossiya will swap from Japanese to American designs after 1942

Importing or making under licences ?

If importing then I think you will be in trouble from 37+ (unless later you join in and get LL).

I'm also not that sure that such a major power would buy in (totally rather than just a few types of design) its ships or weapons.
