Re: Netherlands design study for 1921 program

[TexanCowboy]

I do like the 88 phasers, though!  ;D ;D ;D

EDIT: No subs are designed here...please use the stats from the table. Walter did that back in the days when we didn't have rules governing subs.

[damocles]

Submarines do not need to be designed, all stats are taken from the tech table.

Can't pass it up. I need the practice. Besides it gives me a feel for what it should look like. 

[TexanCowboy]

I've tried to get the sub rules changed to the WW ones before...if you really want the practice in designing submarines, they've been using SS to simulate subs a lot longer....

[P3D]

I've tried to get the sub rules changed to the WW ones before...if you really want the practice in designing submarines, they've been using SS to simulate subs a lot longer....

SS2 cannot be used to simulate the main constraints of real world submarine design. The main design problem is to balance the desired characteristics in a very limited volume: surface speed and endurance (i.e. size of diesel engines and diesel bunkers) vs. underwater speed and endurance (size of electric motors and batteries), and torpedo loadout. Add in further considerations, like diving speed and hull crush depth, and gun armament.

[Sachmle]

As to the Torpedokreuzer design, borrow away.

Thank you very much. They will show up as the Sachmle class in the next reports.

[Sachmle]

Danke. However, if you're going to lay it down in 1919, or at least before you finish the 1917: Engine year equals laydown year tech you'll have to use 1916 engines, which will drive up the weight.

[damocles]

Its in the 1921 program. I think I'll have the 1920 engines. at least I hope I will.

[ctwaterman]

To my knowledge the Duty should have completed the 1917 Engine no latter then HY2 1919 at the absoloute latest....  there were a few other tech that can be found in Korpens 1916 HY Reports like the 1912 Fire Control that was completed that Year.  He was the first to have it to my knowledge.

[TexanCowboy]

Love the fish-torpedo's....  ;D

Above-deck torpedo's are not a good idea on capital ships.

[P3D]

Cut overall length to 220m  (so it would fit in the 220m docks), and I'd marginally increase the armor (+1" belt+barbette, +2" turret sides), and deepen the TDS to 9m, otherwise fine.

And check the torpedo diameter, model torpedoes are effective only against model ships :P.

Above-deck torpedo's are not a good idea on capital ships.

How many American ships were long-lanced by torpedoes in Iron Bottom Sound?

Not many of them died by gunfire. I think maybe two of twenty seven lost.  

There was a couple of recent naval disasters where the Dutch were on the wrong end of a torpedo exchange.

Cut overall length to 220m  (so it would fit in the 220m docks), and I'd marginally increase the armor (+1" belt+barbette, +2" turret sides), and deepen the TDS to 9m, otherwise fine.

If I do all of the above I add another three months and another 2 BPs to the cost of my frigates. I have two DeRuyters left over from Korpen. I have a pair of Arnheims planned along with a few Sechmles and Ardans. I can't build as big as some here can, so I have to build with a different design philosophy. The fleet has to be able to fight, not just sit out a war.

So fast battleships, some light cruisers and a few other ships designed to fight in confined  shallow waters far from home.

I have a definite strategic doctrine in mind. Look at it from this point of view. What did the Dutch actually build for Indonesia? They built light cruisers. I'm working on a 4000 ton design that when I get it finished will look something like this but hopefully better.

The rational is of course something that can fit in a 120 meter dock, cost 4 BP and give a good account of herself in a torpedo and gun brawl and still act as a fast mine-layer as well as a open ocean convoy escort. The 7700 ton cruisers of course are  for fleet work. They cost 8 BP and 8$ apiece. Not as cheap as a throwaway cruiser that costs 4 and 4.

The destroyers make sense, but they lack range and they can't do everything a cruiser can do.

I'd recommend some armor.
