Okay, how about this? On the naval thing.
Ships up to 65,000T this game year, in 1929 you can go to 70,000T standard. If your ship is over 62,000T standard you have to add one quarter for extra trials time save for units laid at least six months after the first (lay any in Q2 and a ship laid in Q4 or afterward is exempt from the extra quarter). Once those first ships complete the extra trial time is erased.
We'll repeat the same standard with 70,000+T ships... if anyone's nuts enough to build one.

Nominally it reflects a country lacks the workforce to be above a certain industrial threshold, but you do have a point there. As such I won't oppose people building more industry.

Well, fine. Now I can design a completely new class.
Oh, and why 62000 as the cutoff point for extra trials? Anything over 60000 tons should get that extra trial treatment.

Because I was thinking of the "1 month trials/1,000T over" ratio and also considering the 7,000 jump figure to be a bit more generous than 5,000 as proposed.
And really, is one extra quarter of trials that big a deal? I'll just take the extra quarter and field
Excalibur as a 64,000T design.

No, it is not that big a deal. Except that I haven't really designed a 65 or 60kt ship yet. Because I was under the impression that someone building a 70kt yard was actually allowed to use it.
This means redoing two years of budget drafts, pushing back the replacement schedule for my BBs further because the new ones coming in service in 1929 won't have the same capabilities as the others....UGH. Frustrating.

Well, at least I have got more IBPs left now with which to increase my other forces, then, so it is a bit of a bonus with regards to that.

Well it's settled then, I guess I will be building bigger ships...eventually. However, I can't afford to wait 3-4 years to lay down any new capital ships, so my next building program (which I hope to finish by the end of 1930) will proceed as planned. These will include two classes of 50kt capital ships; a battlecruiser design mounting 3 x 3 40cm/50s, and a battleship with 4 x 2 45cm/48s, in both cases firing superheavy shells. Carriers in the 20-25kt range are also being studied.

Anyway, I have written one major fluff post (the artillery - it does not matter what artillery one fields because they are supposed to have the same value) and one storypost. I'll try to write more about the Dutch resistance tomorrow or on Tuesday.
Oh, and Germany will limit herself to 60kt battleships, though battlecruisers will be 65kt.

Okay, looking over my latest naval orbat and queues (which will be posted shortly) I have decided that some of my older ships are surplus to my needs. This includes nine 13-15 year old light cruisers (equivalent to the British town-class), eighteen 10-12 year old destroyers (950 tonners, with 3 100mm guns and 8 TTs, 34 knots, added depth charges), and eight Holland 602-type submarines. Note that I'm merely gauging interest here and these vessels are not actually for sale yet (they won't be until I make it official in the story thread). Just want to see if some smaller navy MIGHT have use for them.

Lascaris, how can you start building four liners when every single one of your slipways is filled with capital ships? Liners still take slipways, even if they only cost a third of an equivalent tonnage Navy ship.

Oh this fall victim to merely 3 slight problems.
First ocean liners were often enough built by civilian yards that had nothing to do with large scale military construction. Frex the 3 Olympics each of over 45,000 tons were build by Harland & Wolff which was not involved at capital ship construction. RMS Oceanic projected to be 60-80,000 tons in the 1920s was also laid down at Harland & Wolff which remained still out of the big warships business till the 1940. So no what battleships or carriers I build has nothing to do with civilian shipping.
Second the slip sizes are completely out of sync with the size of the new ocean liners coming up in the 30s. The two Queens were well over 80,000 tons. Normandie was of the same size and the follow up to it Bretagne would amount to a mere 97,000 tons. I short of doubt it is holds any logic to claim France cannot build Normandie or that Normandie (or worse Bretagne ) sized ships are not technically feasible when they very clearly were.
Third the shipbuilding capacity listed is what a country can use on military naval construction. I expect that there isn't any serious doubt that any of the main industrial powers can produce merchant ships in quantities far and well in excess of that. If you want to use your slipways and shipbuilding to produce yet more civilian ships it's I suppose your prerrogative. To claim though that you can build large civilian ships only in military yards... no.
Re: SDN World 3 Commentary Thread III
Posted: 2010-03-24 10:15pm
by CmdrWilkens
The counter-point is that such ships would be civilian crewed and civilian owned (any government ownership percentage means use of slipways and IBP capacity)...so the ships would and can exist but should you ever need to convert them for military needs it would take a couple months AFTER you seize them.
