A Design or Two

The European Naval Design House, based in Geneva, Switzerland is a private company with designers from all over the world. Its first design is for a post-cleito heavy cruiser for the Royal Canadian Navy. Please note that this is the company's first design. Also the company is not affliated with any nation or alliance and is free to design for all.

While the second one looks more balanced than the first one I question the value of a belt not covering all vitals (both designs). I also think you will be better off with a lower l:b ratio, especially for Design 1. Mounting these guns on such a slim hull asks for problems. Speaking of armament: Why are there 6 turrets on Design2? A torpedo bulkhead also is of questionable value on such hulls. The TB alone cannot stop a blast to damage your vitals. There is room needed to allow the gases to expand. This is not the case when using a slim hull - it might not even with a beamier one as you need at least 3-4 meters on each side and thoise you´ll never have on a cruiser, even if relatively large. What´s the idea behind a 3" coning tower?

As I recall, Springsharp does attempt to account for void spaces when you put in a torpedo bulkhead. It's most noticable in high speed designs with a high hull space % already.

Adding a TDS to those designs causes the %space used to shoot up, and the length of the critical areas increases.

I believe I then was able to use bulges to maintain a constant overall beam, but then decrease the interior beam to get the the same %space and critical areas on a non-tds hull, mimicing the voids. While they do decrease on smaller beams, there is still some allowance.

With mines, aerial torpedoes, near miss bombs and shells, there are several threats below large torpedoes that may be minimized.

Couple things on the post-Cleito light cruiser design:

First, submerged torpedo tubes are probably not the way to go. They went out of fashion on surface ships during the WWI period for good reasons, and they're unlikely to come back.

Second, on a cruiser, I'm dubious about the very light conning tower armor. While there are problems with very heavy conning tower armor on capital ships, light armor like this ship has on it's conning tower seems to make the command crew very vulnerable to light and medium shells.

WAY, WAY too low. For a cruiser, a BC of 0.45 is considered low, most are closer to 0.48 or 0.50. You can probably afford to narrow the hull a bit to make up for increasing the BC.

A 3" plate is just enough to trigger heavy AP shells. So you are probably better off without....

Thursday, January 24th 2008, 1:52am

Depends. Are you trying to armor the ship against heavy AP shells? Or are you trying to armor it against lighter weight HE rounds? In the case of a cruiser, I'd submit that the latter are much more reasonable a threat to try to protect against than the former.

Well, "heavy" in this case means heavy for a cruiser which is either 15cm or even more so 21cm.

Some (long) time ago I had a nice discussion with Lord Arpad regarding plate thickness and protection against shells. We run all available programms and simulations and consulted well-known experts on the warships1-boards. To sum it up: You need a 80 to 85 mm plate to make sure a 15cm shell does not pierce at reasonable battle ranges (about 10000 meters for cruisers). Of course deflection etc. plays a role but 80mm@10000m turned out to be good enough for a rule of thumbs even if it´s not entirely perfect. The more, the better of course (for example a 15cm L60 with a 50kg shell can pierce up to 140mm at such ranges under ideal conditions but such conditions are rare).

So I´d say a 3" is not safe against cruiser fire but thick enough to slow shells and set fuzes, assuring a lot of damage is done.

There is a reason why only few cruisers had CTs historically.....

This design is one that places 12 9.2in guns on 13500 tons displacement. It therefore sacrifices speed and endurance for some degree of firepower and protection. Ideal for Med nations or those that do not have large distances to patrol, and are outnumbered by 8in treaty cruisers.

A bit? try 10000 tons heavier

Heres the revised design. However, I had too shorten the armor belt a bit to get the 10in main belt. Dont you think its a bit much though? I mean its only designed to fight cruisers with 8in guns. Also had to take a turrent off in order to keep displacement from reaching cruiser-killer levels.
