Russian Ships for 1946

So I need to take a short break from playing World of Warships and do something with my warships over here, huh?

Currently, the Baltic Sea Fleet has a pair of old ex-British ex-Canadian ex-Latvian ships, the Rynda and Izumrud, which are... well, they're not going to stay on the books much longer. Their 1939-40 refits had some modern 130mm guns, however - a total of four twin 130mm and twelve single 130mm guns of the latest vintage, as well as some modern 37mm quads. With these two ships going to the razor-makers, I decided to take the twin guns and mount them on a single light cruiser of modern design for service in the Baltic. Ergo, two ancient cruisers will be replaced by one modern cruiser. Consideration of building a fifth Avrora class cruiser was rejected due to cost considerations.

This is basically a stretched version of the latest "torpedo cruiser", beefed up to have command spaces and better armour (i.e., it actually has some sort of armour!) at the cost of a bit of speed and the numerous / oversized torpedoes which go into a torpední kreyseri.

The design may be reused or modified in 1947 as a replacement for the badly-aged Saratov and Tambov class cruisers. Both of those classes were designed as carrier force escorts, yet they have little to no growth room to mount radar or modern fire control - a shortcoming which may result in their early retirement.

Each of the reused turrets weighs in at 23 tons (per Springsharp) for a total of 92 tons. The reused 37mm quads weigh 2 tons apiece (again per SS). Thus the cost of the ships will actually be 4850 tons. Strong savings, much wow!

And here's where the single-gun mounts from Izumrud and Rynda are recycled, in lieu of anything else. Although I considered a trio of fast 4x130mm-armed minelayers or some weird and wacky coast-bombardment monitors, I decided to mount the guns here rather than inventing increasingly-expensive and ridiculous designs *just* to reuse some guns. I wanted to build these anyway. Two ships planned for 1946 and two more for 1947.

A grand total of 33 tons savings (per Springsharp) for each ship. Woot!

Your CL has two big problems:

1) Hull strength is 0.94 causing strain, this should be fixed
2) Design has no deck armor

Your CL has two big problems:

1) Hull strength is 0.94 causing strain, this should be fixed
2) Design has no deck armor

Only the latter point is really an issue, since our rules permit combatants of 4,500 - 6,000 tons standard to have a hull strength of 0.90.

If you'd like to compare another version with an armoured deck, here's a variant. Currently only intended to protect the ship from strafing by aircraft; designing in an armoured deck to resist bombs or rockets would result in prohibitive expense.

I didn't realize cost was an issue, but deck armor is a good thing...

Overall a nice design if you need numbers without breaking the budget.

Overall a nice design if you need numbers without breaking the budget.

I'd say it's not so much an issue of cost - although that is a factor - but rather because ships assigned to the Baltic Fleet are intended to be somewhat expendable. The presence of so many aircraft, and shallow waters that are perfect for mine warfare, mean that the VMF Rossii doesn't anticipate a long life-expectancy on large warships (such as heavy cruisers or battleships) within the Baltic. I want the ships of the Baltic Fleet to be of fairly high quality, of course - but I'm not going to invest so much into them that their loss would be a severe blow to any hypothetical Russian war effort in that theater. What is the cost of a destroyer or two (or even the occasional cheap light cruiser) to a navy that has as many as the VMF Rossii?

Monday, May 4th 2015, 9:50pm

And now, a new class of destroyers. It's uncertain yet whether or not these ships will go to the Pacific Fleet (to replace the twelve Izyaslav class destroyers) or will join the Northern Fleet as part of the screening element of the lineships and aviation-cruisers. The latter option seems most likely, although the Pacific Fleet is in desperate need of replacement DDs.

Looks like a very reasonable design, though they will require larger building slips. I guess that is the price to be paid to keep sea-handling in line with the growth of armament and sensors.

It's not a very steep cost. Fact is, most of the Class 1 slipways are already scheduled for other construction, and even if these ships fit in a Class 1 facility, I'd have to build them in Class 2 or Class 3 slips anyway. And drydocks aren't particularly an issue at the present time, at least for the Northern Fleet.

Russia is blessed with a diversity of shipbuilding facilities. Some of us less so. One of the reasons Germany is investing in upgrading facilities is to "correct" the split between many Type 1.0 and few Type 1.5/2.0 facilities. And don't get me started on Yugoslavia's options... :(

I changed the design of Serdityi to become a near-clone of the existing Russian vessel Kharkov. The new design is slightly larger, but has better seakeeping and "soft stats" - nice attributes for a ship bound for the Northern Fleet.

Currently, Russia has four "escort cruisers" of the Varyag class, armed with 3x2 234mm guns. They're basically small, long-ranged coast defense ships. I've been puzzled about what to do with these vessels, as they don't fit very well with the plan I have for the VMF Rossii, and they're a relic of the Treaty Era. Really, it's too bad I can't re-use those lovely turrets and build something faster, with a first-rate AA battery, which I can use as escorting forces for the Northern Fleet's carriers...

This is not really a design optimized for surface combat - there are only six guns, and the belt armour is weak against large caliber shells. However, I envision these ships to be part of the close AA defense of the Russian carrier squadrons, using their electronics and secondary batteries against incoming air attackers - and their combination of size, seakeeping, stability and steadiness give them more advantages than a smaller cruiser.

The alternative, of course, is to just build more Avrora-class CLs. Unfortunately for this design idea, that's the "smart" thing to do. Avrora class is cheaper, with a dual-purpose main battery that makes up for the fewer and smaller secondaries...

Just refit it and add a bit of miscellaneous weight to it for the radar and other stuff on it during refit (as long as the refit covers that stuff) and then do a minor increase in draught to match the added weight and then decrease freeboard with the same amount as was added to the draught.

I see various times nonsense like "for future growth" or "growth room" in the miscellaneous weights breakdown. I'm pretty sure that the builders of old weren't like "let us put 100 tons of ballast on the design because we can remove some of that in 15 years time so we can fit a radar and other stuff onto the ship when it becomes available." I'm pretty sure that stuff was just added to ships and they ended up becoming a little bit heavier with the extra weight. I think that the "growth room" bit is especially weird. It kind of sounds like "we need this bit of area in the ship clear because 15 years from now we need to put this room in that place that has all this special equipment to detect things."

I see various times nonsense like "for future growth" or "growth room" in the miscellaneous weights breakdown.

I mostly use that as a sort of term for "other minor assorted equipment I forgot but shall remember a couple months from now."

Speaking of things that I forgot months ago and just remembered, I never did post the refit scheme for the secondhand German destroyers bought up by Russia. A bit of speed is being lost with the replacement of the engines, but it's minor. The big change comes with the replacement of the inferior German 150mm and 88m guns with superior Russian 130mm and 75mm main guns.

Given the higher-than-average values for seakeeping, stability, and steadiness, I intend to deploy them to the Pacific Fleet.

I strongly disagree. That is the reserve for the design and not actually fitted with ballast to take off at a later date. Ship designers almost certainly design larger ships to have a reserve for future items and as Brock says most people don't always have a complete, detailed, methodical (to the point of being silly) list of items to tally up every single gram of misc tonnage. I've found that my older designs have under or over stated weights on items and I've edited their misc weights to reflect more accurate information.

Actually, as destroyer guns go, I would agree that the German 15cm SP is an inferior weapon to the Russian 13cm DP. I inherited these ships from Hrolf and I would have never put SP guns on them.
