Latvian Ships 1938

I will be redoing the 1938 reports. That means I have 4,000 tons to play with. I know I will be setting aside 1,000 to purchases,(contact me if you wish to sell). That means I have 3,000 tons. I know I will be building some midget subs. Any other suggestions?

Midget subs? Do you mean small coastal subs, being just small, short ranged submarines? Or true midgets, useful mostly for delivering swimmers?

I'd be inclined to order a couple more of your current coastal subs, a couple more minelayers, and perhaps another Riga-class cruiser. After that, more torpedo boats and destroyers.

I'd agree on what Hrolf says for the most part with perhaps more subchasers on the list. A light cruiser wouldn't hurt either.

Hmmmm....I have five of the "light cruisers" that are really closer to Russian Torpedo Cruisers. I have one armoured cruiser. I'm working on a faster Riga, but it isn't working.

A faster Riga will take a lot more tonnage, for Latvia I wouldn't bother.

Did I say faster? I meant upgraded.

I assume more AA? Her main and secondary guns are fine unless you want to shoehorn in another 9.2" turret.

Gatling guns? Woo boy, this should be fun to watch!

*Gets cheese, crackers and a root beer.*









[SIZE=1]For two years I've wondered about introducing gatling guns, but have never got up the nerve... [/SIZE]

(Sails up besides a random ship)

"Dance for us!"

"What, we haven't done anything wro...(sees the guns).Yes Sir!!!"

Not real gatlings, but it was felt that this would allow more firepower to bear on the sky with less crew than other methods.

I'll start by pointing out that there are NO period Gatlings, of any form, let alone a 37mm version.

12

Friday, December 18th 2009, 11:48pm

Actually there are, both period weapons and 37mm versions (Walter?). Now a working 8-barrelled 37mm gatling... well, it can be done, but the engineering behind it would be daunting, and the reliability... well the less said the better.

13

Friday, December 18th 2009, 11:51pm

Perhaps a 37mm 8 barrel version of the Spanish Meroka then?

14

Saturday, December 19th 2009, 12:36am

How are you going to load new clips into the "37mm Meroka"? No.

15

Saturday, December 19th 2009, 12:40am

Why? You strap 8 machine guns together, connect the ammo feed into one connector, and fire. If that doesn't work, than it won't be a gatling, but a 8 barreled gun with different feeds but a comman mounting.

Might be better off with quad 37mm's mefinks. More reliable, simple and you don't leave all your guns in a few mountings that once destroyed seriously reduce your firepower.

That said 64x37mm guns is quite a number but then again I'm used to spliting up my AA between 40mm and 20mm and backing it up with a few 50cal weapons too.

17

Saturday, December 19th 2009, 1:57am

Hmm...could a double quad mefink work?

18

Saturday, December 19th 2009, 2:00am

Perhaps but your creating quite a large mount. Personally I'm not a fan of putting all your eggs in one basket, big or small. I've stuck to twin 40mm for now with my fleet, even though Chile has been cooking up designs with quad mounts in mind. I may yet make the transition!

Yeah, I need to go back and down those to twins again.

A general rule of thumb is that the more guns you add to a mount, the lower your rate of fire from each barrel.
