Not really. Removing weight from the sides of the hull doesn't compensate for adding stuff up on top.

I agree with Brock. Old, basically useless. Just beach her and put some simple mounts the army can use instead.


There's some scope for that tradeoff, depending on where the bunkerage is: you might get 50-100 tonnes of topweight like that, but she's likely to be quite a stiff seaboat and have poor damaged stability. Those might be considered acceptable tradeoffs for a ship supporting a coastal squadron, though I wouldn't bother myself. This ship is what, 25 years old? After that long in service, even with regular refits, she'll be in a pretty poor state: primary hull structure will have experienced rather a lot of fatigue and the machinery will be in a pretty bad state. Again, you might get away with it in sheltered waters, but it's a risk: one of these days, she's liable to suffer some form of calamity.

He's getting new engines....as for the hull plating, its in the Baltic, where heavy weather shouldn't be that bad.

The Baltic has storms just like every other sea.

The Baltic may be an enclosed sea, but it's still quite large so (when not solid, see below) can get quite respectable seas up. Also, the Finnish-Swedish Ice Class Rules rules form the basis of much of the world's rules for seasonal icebreakers and ships which operate in ice: this isn't a coincidence.

In any case, I did say that this is a tradeoff that might be thought acceptable, although I wouldn't take it myself. It's quite telling that 20 to 25 years is generally considered the 'natural' life of a ship.

But by comparison to, say, the North Atlantic, they aren't that severe.

Seems to Russia has been done, looks like a dodgy second-hand car dealer manager tarted her up and had some slick chat to get the Russians to buy the Birkenhead.

Really I can't see why Russia which has ample home-grown capacity and more modern designs wasting time and resources on this elderly ship.

To operate radars she'll need more generator capacity plus lots of internal space to store all those valves and black boxes and some kind of CIC to make sense of the radar data and feeding that to a fire-control predictor. Really Russia should scrap it and recover what it can from the wreckage.

More good points. I can take off some of the high tech and hull strain.

1st Battle Division still could use an AAA escort, and a training ship is always needed. 1st Battle Division only goes 18 knots, so a 10 knot speed advantage should allow Rynda to interpose herself against an aerial threat.

Why have a 130 mm battery and a 100 mm battery on the same ship? It just complicates logistics, and it doesn't add that much to the ship. I would recommend removing the 130 mm's and replacing each twin mount with two twin 100 mm, with two on the turrets and two on the broadside.

35

Thursday, May 20th 2010, 3:11am

The 130s add a little range and punch for anti-ship work.

It would also be a bit tight on the broadside with another 100mm mount to fit in.

36

Thursday, May 20th 2010, 3:13am

Then add in 6 100 mm, all on the turrets?

37

Thursday, May 20th 2010, 8:02am

The 130s are not on the turrets

They're on the superstructure behind the turrets, with their own ammo hoist.
