Edit: Removed double posting of some of Kiev's stats.

On the Kiev class, you probably don't want the 130mm guns as quick firing, that's getting pretty heavy for most navies for a man to manhandle.

What about the American 5" and British 5.25", were they not man handled?

Both of those were 2-piece rounds (ie, projectile and propellent cartridge are separately handled and loaded), not a single fixed round (which is what quick-firing means).

There are a few designs with vera high l:b ratios, transome sterns, low BCs for their size and very high bunkerage to get down their size....

I´m not going to start THAT discussion again. I´m tired of it. So I just state my opinion: I don´t like them and IMHO those designs would have real problems in OTL with highly stressed hulls.

The high bunkerage business works. However it comes at a price and lately I have been wondering if it is really worth it to waste all the valuable hull strength on the many hundreds of tons of additional fuel which could be better spent on other aspects of the ship...

Example: Earlier today, I changed the range on one of my BB designs from 11,000nm at 20 knots to 10,000nm at 15 knots. I altered the dimensions so I would be back at the same standard displacement. I went from a hull strength of 1.00 of the 'original' sim to 1.08 in the new sim and I think that that is quite a lot.

650mm torpedoes.. that's scary.

Where will the torpedo-cruisers be stationed, do you imagine? I think they'd be more useful in confined waters (the baltic, say) than in the Far East..

(Keep them away from me!)

According to the current gentlemans rules...

Point 2: Length:Beam ratio.
(as currently proposed)
a) Ships of 8000 tons and smaller => maximum 12:1
b) Ships bigger than 8000 tons => maximum 10:1

If theres an issue, I'd like to put it to rest once and for all....

Missed that part. 26" torps, ouch. Historically used for Russian Nuclear Torps. Could we at least see some miscellaneous weight on that cruiser to account for the ~24+ standard tons worth of torpedoes ?

Also, presuming the Torps are about 7m long each, and there are 4 centerline mounts, thats 28m or nearly 20% of your length that has to be clear. Will all weapons fit?

Hmm do I hear bids for 700mm torpedoes, 750, 800 ? 800 going once, twice, Ahh the Gentleman with the..pet white mouse... sold to Mr. ....

Also standard for Russian wake-homing torps, and one of their sub-launched anti-sub missiles (SS-N-16). The Imperial German Navy looked at a 700mm torpedo that was around 9m in length late in WWI, but as far as I know no real work was done on it.

The page I was looking at listed the 650mm wake homing as a subsequent development of the 650mm nuclear version.

As for length, 7m was simply what Dutch 21" were, others were shorter or longer. You reference a 700mm at 9m, while the 650s above were 11m, either of which would make the deck space difficult.

On the other hand, at 145m she is longer than many destroyers sporting a similar weapons outfit.

Russia's experience of her last two naval wars drives the requirement for long range. The lesson of the Russo-Japanese War is that Russian fleets may have to steam long distances to get to where they need to be. The lesson of the Great War is that Russian ports that are geographically blocked are no place to base Russian seapower. Before the Great War, Russia's trade was conducted through the Black Sea and the Baltic Sea. Once war broke out, Russia's access to the World Ocean was essentially cut off, except for tiny trickles through Arkhangelsk and Vladivostok. This had a dire impact on Russia's economy and war effort, and was a huge factor in the failure of the Russian war effort.

This led the Russian Naval Staff to conclude that the main base of Russian sepower should be at Murmansk, since it is the port with the best access to the ocean that Russia has.

However, the isolation of the main Russian naval base at Murmansk requires that Russian ships steam a long distance before they get to where the action is, and then return. The global network of French bases is a big help, but still does not overcome Russia's unfavorable maritime geography.

Large bunkerage does.

For the Torpedo cruisers, the eventual plan is to have a Squadron with each of the major fleets. And not only are they long, their 130mm armament is grouped forward and 60% of their length is aft of the mid-break. Besides the torpedos, the aft armament is a centerline quad 37mm and 4 dual 37mm on the sides.

b) Ships bigger than 8000 tons => maximum 10:1

If theres an issue, I'd like to put it to rest once and for all....

No, no, all within the rules. I was referring to a different discussion, not our GRs....

Hmm do I hear bids for 700mm torpedoes, 750, 800 ? 800 going once, twice, Ahh the Gentleman with the..pet white mouse... sold to Mr. ....

The RAF trumps them all with the 38" (965mm) x 29ft "Helmover" Torpedo. Radio guided with a range of 50 miles.

That was the small version that fit into a Lancaster's bombbay.

The ship launched version was 38" x 49ft and weighed nearly 10 tons. 150mile range.

How long until you can launch mini-subs from inside these tubes?!

...wait a minute, I thought the Philippines had the copyright on the BIG BANG™ theory of naval development.

Canadians are working on the "Great Air Burst or Bust" Theory.
