Danish Naval Plans

Present Situation
The last quarter sim report posted was Q3/1941 - that makes for 2 Q and 3 Years to catch up, including Q1/1945 - a total of 14 Quarters.
With 11 factories in Q3/41 and assuming no new factories come online - I have 154,000 tons to play with.

The OOB, as I counted was:
4 BB + 3 BM
2 CVL + 1 CVL(x)
3 CA
21 CL
56 DD
70 SS
17 MP + 23 FS + 79 PC
3 AUX (Yachts, etc. not counted)
A total of 282 useful ships.

The problem is many in this force have very marginal usefulness. They have knife's edge stability & seakeeping; 1.00 to 1.03 of both. The count of such ships is:
2 BB + 1 CA + 4 CL + 56 DD + 62 SS + 11 MP + 20 FS + 79 PC, a total of 175 ships.
That's 62% of the navy.

I am not as concerned with ships with low seakeeping, especially the DDs, but those with low stability.

The most immediate problems are:
1 x Einmyria-class CA, 1.03 Seaboat and 1.02 Stability
60 x UE-class SS, 1.00 Stability and 0.400 CB (illegal)
1 x Gemini-class SS(x), 1.00 Stability
1 x F-class SS, 1.00 Stability
3 x Insect-class MP, 1.01 Seaboat and 1.01 Stability
18 x Lake-class PC, 1.00 Stability

Disposals
The immediate problems - the UE, Gemini, F, Insect, and Lake class ships will either be scrapped, sold, or expended in experimental trials.They are a safety hazard as is. The Enimyria will either receive a bulge or be converted into an AOR.

The Garrya, Hedera, Empetrum, and Fuchsia FS ships will be halted on their docks and scrapped. The Uf13-18 will be halted and scrapped. The LTC25-28 will proceed as planned but new ships of the class will not be laid down. The Falster and Bornholm CLs will continue as planned.

New Construction
From 1941/Q4 to 1945/Q1, 2 CVLs + 4 CA + 4 DD + x AOR/AOSS will be built. Going forward from 1945/Q1, Denmark will focus on replacing SS, and constructing AUX ships. 2 more CAs may be built.


As of the current designs, about 34,000 tons will be left to complete the ships under constructing/reconstruction and build new AOR/AOSS ships.

The destroyer needs to be altered slightly. The gentlemen's rules state:

Quoted

b) Relative cross-sectional hull strength of light fast combattants of 0-3,000 tons standard should not drop below 0.5
c) In general, light fast combattants of 3,001-4,500 tons standard can have a minimum relative composite hull strength of 0.75 as long as it does not cross the limit as given in point 1b.

Considering that it is 3000 tons light, either the ship's hull strength has to increase to 0.75 or the ship's displacement needs to be lowered to 3000 tons standard.

An interesting assessment of the current state of the Danish fleet, and it seems that Danish ship-breakers will be busy for quite some time.

Generally speaking, I side with you in desiring greater stability and sea-keeping in my designs; however, in the first several designs you have posted it seems the pendulum has swung too far perhaps.

I envy the sea-keeping of the carrier design but its stability is only marginally improved over the designs you have condemned. Also, in the desire to obtain a very large air group you have left the vessel almost devoid of armor protection. In a smaller vessels I could understand this, but 20,000 tons is a rather large investment. Technically the design appears acceptable but I have doubts of the wisdom of the choices made in this instance.

The cruiser design exhibits some of the same issues – too much emphasis perhaps on sea-keeping and not enough on stability. My own preference, if attainable in the light of other characteristics, is a minimum of 1.10 stability, if not 1.15; for that I am willing to sacrifice some sea-keeping and/or some speed. Other than that I like the cruiser design, if it is a bit on the costly side; but then you do have several years-worth of tonnage to spend.

Walter has commented on the destroyer design – as posted she does not conform to the Gentleman’s Rules. She also does not have much more sea-keeping than the designs you dislike, though her stability is better. When considering what adjustments to make, you might wish to give thought to increasing her magazine capacity – I think automatic guns would go through 300 rounds rather quickly.

For the carrier design, I believe it's a difference in the belief of the threats it will face. My design is meant to defend only against enemy aircraft, not surface combatants - the reason being that a carrier in range of a surface combatant is most likely lost regardless. Hence the ship has a torpedo bulkhead and machine-gun protection - but not heavier armor.

Looking at the carrier, I have a bit of a thought that Bruce is probably looking (as I am) at the 25mm armoured deck, which is about a third or a quarter of what has been used on historical carriers of this size category. If you say the defenses are organized against aircraft, then the deck armour should be much thicker in order to allow the vessel to better survive hits from dive-bombers (or the increasing threat of rocket-equipped aircraft).

7

Wednesday, August 13th 2014, 3:07am

The idea is somewhat similar to the US doctrine cirac 1940.
"No practicable armored deck could resist any bomb; it would be better to face the fact that the bombs would get through and either prepare to accept the consequences or try to stop the bomb deeper in the ship, where protective weight was easier to accommodate." - Friedman, 208

In this case, Denmark chooses the former. The OTL Fritz X, for example, was rated and tested with a penetration of 160mm Wh/n.A. single plate at 30 degrees from normal.

8

Wednesday, August 13th 2014, 6:05am

Indeed, I was concerned with the general lack of protection for the aircraft carrier design, the more so due to the rather large size of the proposed vessel. On a 10 KT CVL I would be less concerned with the minimal protection proposed; to me, 20 KT is a lot to spend on an eggshell. I am in complete agreement with you that a CV needs to be protected solely against air and submarine threats - though truthfully that is a position not fully tested here in WW, and one not wholly supported. But I will admit that your doctrine is valid and has some merits borne out by OTL wartime experience. Of course, that experience also includes the USS Franklin.

And, for what it is worth, both the Fritz X high altitude guided bomb and the Hs293 glide bomb are in service with the Luftwaffe and Marineflieger. :D

I'm wondering if the heavy cruiser design really needs two superfiring turrets...

I'm wondering if the heavy cruiser design really needs two superfiring turrets...


Well, if you want all three turrets to fire in the forward arcs, you do. Of course, it does concentrate a lot of weight forward and rather high - both the Brooklyns and the Mogamis, each with three turrets forward, only had one superfiring turret, with the other carried at deck level and unable to fire directly forward. Me, I would have had only two turrets forward and two aft, and used the vacated centerline space to add twin 13cm AA guns to cover the forward and after arcs.

Noting that the cruiser and destroyer designs have only 2cm LAA guns while the aircraft carrier design carries mid-range 4cm LAA guns in addition to its 2cm battery, is there a doctrinal reason that the 4cm gun was left out of consideration for the surface combatants?

11

Thursday, August 14th 2014, 4:15am

There's no particular reason for the superfiring guns and lack of 4cm guns - I simply forgot to change them after some details were eliminated.

Nice to see some new Danish ships.

Overall I like these. The CA is very expensive, but decent ones are and this one packs a serious punch. The CV is perhaps an eggshell but then any carrier operating in the North Sea is toast unless you go down the armoured carrier route. I'm sure the high 35kts speed has increased weight and space requirements on these ships but its a doctrine that's common in Wesworld and has an Italian flair to it, perhaps an IC influence from the days of alliance with Italy?

It is the latter - the 625t are for the 25 aircrafts. Is the wording not clear or do you have some other misgiving?

On further reflection I realized that I was reading too much into it - hence my decision to delete the question.

The CVU10KT is an interesting design and makes the Danes the second navy after the RN to operate such a type. Certainly handy for overseas operations, an expensive luxury perhaps but I think its one worth having if you've got the tonnage to spend.

On the new CA I see lowering "Y" turret allows for a 40% larger Secondary Battery. i consider that a worthy tradeoff.

Excellent (if very $$$) design!

Warning: Date too early for rapid fire gun - Main battery

The warning shouldn't be an issue given that the guns are newly installed (1941) - or is it? No idea.

In this case, since the guns are newly installed, you should change the date on the guns to 1941. It may change the weight of the mounts slightly, but then the error will go away. Make sure to check before-and-after shell weights, too; and change the dates on any other armament that may be removed and replaced.

I do not know whether the date of the automatic guns is a violation or not, but she seems to be in violation of Point 1 of the Gent's rules; her hull strength is less than 1.00
