New Russian ships for 1939

Major new projects for 1939 will be reconstructing Imperitritsa Ekaterina Velikaya, and Poltava, refitting more Rosa class corvettes, refitting Tashkent class destroyers built in 1922, and building a class of modified Besshumniy class coastal submarines.

Modifications to Imperitritsa Ekaterina Velikaya are: conversion to oil firing, new turbines, a reshaped bow, bulges, replacement of 305mm/52 triple turrets with twin 381mm/45 turrets, removal of end belts, a new antiaircraft suite, increased deck armor, a comprehensive electronics fit, and refurbishment of systems and fittings for service life extension.

I'm not sure reconstruction of the older battleships is particularly useful. They're basically useless but are going to cost as much as a modern battleship to operate.

I think You underestimating the old steel.

It is a useful ship, it will still be a treat too any BB in WW, a super cruiser like the ones that are appearing, will be force to avoid those ships.
On the other hand it is old and Poltava tie up a type 3 drydock that maybe used for a cruiser.Ekaterina is shorter and will only nead a type 2 but it is still a problem.

Old BB's owner have 3 choice's.
Sell, scrap or modernize.
It appears AdmKuznetsov thinks this ship has a part too play.

I think it's more a case of our rules not really reflecting reality. Ships like this are so old and worn out to be completely useless. It's really only for second line duties (like simply being in a place) that they have any use whatsoever, and again, operating costs are going to be similar to a modern battleship. They are simply unaffordable except to tie up somewhere and use as a possible reserve if the need is really really dire.

Or Museum-ize! Germany and India have both sent battleships to museum service.

It's still a few years down the road, but I've discussed with TheCanadian putting together a "Black Sea Central Powers Naval Museum" consortium, with Bulgaria's Varna, Turkey's Yavuz, and Romania's Amiral Murgescu all turned to museum ships in their respective countries.

Russia's strateic situation means

that second-class battleships operating on the Black Sea/Med Sea will have their uses, while Russia's main naval power concentration at Murmansk steams the World ocean.

And it's not like the D3 and D2 at Sevastopol are particularly busy.

And obviously, their longevity is indicated by the fact that several of the Ganguts stayed in service until the 1950s.

Thats true, as well both ships are faster than any battleships currently in the Black Sea, and they match or outgun their main armament.

Yavuz, historically served without a refit until the 70's!

You know, I'm thinking about getting something for the Baltic. That way, we can put up a sign that says:

Which seas do you count as the Seven?

Baltic, Medirattean, Black, Arctic Ocean, Pacific Ocean...obviously this is biased.

'served' in the very loose sense. I seem to recall reading that by the time of Missouri's visit to Turkey between WW2 and Korea, Yavuz was basically unable to move on her own power. I'd expect a nation with better ship-servicing and dockyard capacity to maintain an older ship better than Yavuz or Sao Paolo if they chose to, but there's still definately a limit to keeping a ship as an effective combatant.

However, it's also worth noting that the Russian ships are getting a substantially more thorough modernization than most ships in WW (75%, rather than 50%).

Thursday, February 4th 2010, 4:00am

They're planned as 50% refits

I'm not cutting them in half, or reworking the stern, or changing barbettes.

The main battery changes are replacing the triple 305mm with twins, using the same ~9m barbettes.

14

Thursday, February 4th 2010, 4:55am

I doubt the 15'' guns could fit in a 12'' barbette. I use 2'' increments as a upper limit, that is, a triple 12'' could fit in a twin 14''.

15

Thursday, February 4th 2010, 10:54am

It would probably fit, consider the planned (but interrupted) conversion of Gneisenau from 11.1" to 15" guns.

16

Thursday, February 4th 2010, 11:42am

The beam and barbette diameters

aren't much different from the Queen Elizabeth class, and actually bigger than Curious/Spurious/Outrageous.

17

Thursday, February 4th 2010, 11:54am

On the Besshumniy II class, the one concern I have is the use of a single shaft. That's going to limit the vessels's low-speed manueverability, since the rudder(s) need water flow to be effective. You'd be better off with twin shafts which allow differential steering.
