New Russian ships for 1942

We will start with the Pobeda class battlecruiser. She has the same general dimensions and armament as the Slava class battleships that will be completed in 1942, but with higher speed.

Russian Federation Northern Fleet has two battle groups because a single line of battle of such length would be both strategically and tactically inflexible. Battle Group One consists of the modernized Izmail class battlecruisers and the Imperator Petr Veliki class battleships. Battle Group Two Consists of the new Slava and Soyuz Nerushimy class battleships. The Pobeda class will be assigned to Battle Group Two.

Whilst it's obviously cost effective under our rules to buy an almost new ship and then pay very little to convert it to military purpose, how likely is this really?

Isn't it better to simply spend the money on a purpose built military vessel?

I'd agree with this if the cost of a support ship reflected the actual historical cost. As it is under our system, building a purpose-built vessel of this size would cost as much as a regular light cruiser.

I've advocated more realistic rules for this in the past, but that would substantially shift the way Wesworld is played.

If time and money (i.e. tonnage) were no object, a specialist vessel built from the keel up may in fact result in a 'better' vessel, within the constraints of the sim time and money do matter. Moreover, historically mercantile hulls were commonly adapted for a myriad of auxiliary roles and served as least as well as their 'proper' naval cousins.

If any WW nation seeks to build a fleet train of any size while maintaining a combat fleet, it will perforce resort to mercantile conversions, even if it also lays down specialist vessels for some applications.

Two questions about the battlecruiser:

1) What is the Main Battery layout?
2) Is the stern overhang a bit excessive, especially for a ship with a transom stern?

9

Thursday, November 10th 2011, 3:53pm

Main battery is

two turrets forward, one aft, none superfiring.

Yeah, the stern overhang is a bit much.

And its time to refit the 1924 vintage Kursk class destroyer escorts.

In 1942, the Kursk class underwent a partial (25%) reconstruction to modernize them and extend their service life. They got new engines, gun mounts, air and surface search radar, and a modernized ASW suite. RF Naval Staff now consider them a modern, capable combatant.
