That's a *lot* of AA. To compare, I've dug up some historical examples (see below). All of these are cruisers from the 20's. As a reminder: I think it's a safe statement that by 1920 OTL the airplane was a proven tool of war, and contemporary designers were taking into account it's threat. Here, only in the last month have airplanes proven themselves dangerous to ships that are underway. So I think 16 75mm AA guns and 32 15mm MGs might be an overreaction.

Historical ships:

HMS Kent (RN County) 1928:
8 x 8 in (203 mm) dual guns
4 x 4 in (102 mm) single AA guns
2 x 2 pdr (37 mm/40 mm) pom-poms quad guns

USS Salt Lake City 1929:
10 × 8 inch/55 caliber guns (2×2, 2×3)
8 × single 5 inch/38 caliber guns
4 × quad 1.1 inch/75 caliber guns
(I think she probably had some 0.50 inch MGs, but I'd have to check Friedman. The 1.1inch was brand new in 1929.)

Duquesne 1925:
8 203mm/50 Modèle 1924 guns (4 × 2)
8 75 mm anti-aircraft guns (8 × 1)
8 37 mm anti-aircraft guns (4 × 2)
(Cited as also having 4 triple 13.2mm MG mounts, but not sure when they were fitted)

IJN Myoko 1929:
• 10 × 203 mm (8.0 in) guns (5×2)
• 6 × 120 mm (4.7 in) guns
• 2 × 13 mm (0.51 in) machine guns

Trento 1926:
8 x 203 mm / 50 caliber
16 x 100 mm / 47 caliber
8 x 40 mm / 39 caliber AA
8 x 12.7 mm AAMG

I was more concerned about the main gun layout criticism. The NRDN is getting reports that Rift War air attack is FAR more effective than the MVB expected or that is publicly known.  

Not sinkings here, but a lot of very close calls and incidental accumulated damage that would seriously impair operations.  

I still don't think the aircraft is there yet, but the choice here was for arming independent operating ships that also operate as heavy escorts. A 1916 75mm AAA gun is for all practical purposes still just a Zeppelin killer.

You have too much AA guns & MG for a 1916 cruiser.

you could really reduce the MG.

in 1916.., consider also the DDs protection more important than AA protection...
So, choose 100mm or 120 for secondaries & just 4x75 AA

*sniff sniff*  man damage 4 or 5 measely New Swiss cruisers because they were sailing in such close formation that they couldnt dodge without running over their Destroyers.  And then hit a bunch waiting to enter harbor and low on fuel.

In addition all these AA guns are either 20mm and less and therefore revenge weapons the torpedo is already in the water.  Or 75mm and  and basically lack the very reliable timed fuzes for a really good flak curtain.   Fuze setting machines and accurate ranging on a target as small as a plane are a thing of the future.

But yes other then the huge number of AA guns not bad. 

Hey Do we have Limitations for a gun either being a Hight Angle or Low Angle gun.

Shouldn't AA machine guns be in single mounts as then they could be trained manually - and operated by a single person unlike pedestal mounts?

Post by: damocles on July 09, 2010, 04:12:08 AM
The Germans used a 37 mm gatling gun, something much like the old Hotchkiss naval 2 pounder as a balloon burster in 1917. They also shot at planes with it

That was a multi-barrel gun used on ship and land. It was heavy and it was manually trained, and served by gun crews.

I think that my machine guns in their quad mounts are in the same total weight class, effective range, and handled the same exact way.

I'd rather have the MGs in a simple pivot mount, and aim by tracers. With heavy water-cooled HMGs of the 1920s only single mounts would be light enough.

A pedestal quad MG mount is much heavier and IMHO does not worth the bother.

You know I may actually agree with you about that in "principle", but until I get the 50 mm AAA auto-cannon or buy something else and begin fleet refits the 1916 machine gun is ALL I that really have that is a true AA capable gun? The quad example has a better train and elevate than the 1916 75 mm balloon barrage gun.

But lacks oomph and range. How many .50cal hits does it take to take out an aircraft, let alone a balloon, compared to a 75mm round?

They also used the Maxim 37mm aka Maxim Flak M14, basically the same as the Brit's 1pdr Pom-pom, just an old Maxim 37mm on an AA mounting. http://en.wikipedia.org/wiki/QF_1_pounder_pom-pom (http://en.wikipedia.org/wiki/QF_1_pounder_pom-pom)

Yes to both, but I don't have the 37mm or the 40mm: I have 15 mm machine guns, then I jump straight to a 50mm QF. It has to become an auto-cannon in 1925 as well as the 75, and 125?

50mm won't have the ROF of 25-40mm guns, neither the explosive filling necessary to be useful save a direct hit - then they are overkill. Fuses are just too large for the time period. Why there were no such (50-65mm automatic) weapons developed before 1940.

I can see that. I also see that I don't have a 40 mm or 20 mm bore in my tech family, P3D, not right now. That is why I use all those 15 mm machine guns.

There used to be a rule about machine gun (up to 1.099"/27.93mm) being exempt from the research rules, however it has disappeared. I'm not sure as to the current status of said rule. If it is still in effect, you could develop an AA Machine gun w/o cost (up to 1.099"/27.93mm).

Post by: damocles on July 09, 2010, 06:52:13 PM
That introduces some problems in refits. I think that at this point, if the rules permit, I'll introduce a 25mm Model 1920 in a twin or quad pending the development of 1925 AAA.

I'll base it off the Type 96 Japanese auto-cannon.

Actually I've been using the Maxim 37mm all along since it was basically a common 1890s design and so baseline. I'm pretty sure I asked about it at some point and it was ok.  Still, it is antiquated and next up for replacement in Bavaria's line up.

Post by: damocles on July 09, 2010, 07:16:24 PM
The Browning action 15 mm in a quad stack is actually far more effective than the Hotchkiss (or the Vickers) and in that quad version (a la the Vickers mount as Sachmle so graciously cited) would tear any 1920 to 1929 era plane to bits inside 1,000 meters. It would be a revenge weapon, but it would be a fairly murderous flat trajectory high velocity one, which is what I think has caused us all to take a very hard look at it as regards play balance and historicity.

I'm  rather curious to layout and the armor.

The layout, having two quads to the stern and only one forward, means more of a retreating ship than an attacking ship. Given it's speed (27) and armor, I question why such a ship would need to retreat-attack any battle-line.

Then again, your AA is also overkill for this time-period and is completely unjustified. Smells like hindsightis to me.

Also, I do not know of any nation capable of rolling 18" inches of homogeneous steel. Even the maori, renown for their thick armor plates here, can only roll up to 15". There was a reason, I stopped my belt armor at 15" on my design.

Your ship's B/C is quite low for a quad bearing battleship and you also have 0.01 hull strength unused and wasted.

I read somewhere (iirc someone reposted some old discussions at Warship Projects) that the British (who did made the second best cemented armor) found that while contemporary (1930s) heat treatments increased the quality of plates up to 14" compared to WWI KC, but then the difference dropped. At 18" thickness there was no difference in stopping power between new armor and old KC.
So the Japanese approach of thick non-cemented face hardened armor plates for Yamato is somewhat vindicated.

As you roll thicker and thicker armor it gets harder.  There is a reason that the US Standard Class didn't have armor heavier than 13.5" belts.  The biggest problem is quality control. 

To be honest I think we should have some type of limit on armor thickness.  For that mater guns should have an upper end limit on guns.  18" is the largest practical gun size, despite design for 19" and 20" guns, the blast effects are just too extreme.

My 15" belt is actually 1" forward belt and a 14" main belt.

But yes, that was my point miketr.

This isn't the place for this but I've had the thought of extending the armor tech tree where new levels would describe the thickest armor plate that can be rolled.

My understanding is that, at the moment, the Maori are rolling the thickest face-hardened plates in the world, and I've been advised that 'thicker than 15"' isn't really possible. If that restriction gets relaxed at some point, I'll probably go to 40cm plates for my next BB design, whenever that is.

A torpedo cruiser, eh?  I'd recommend more torpedoes.  8 on each side of the ship plus reloads.  This way the cruiser can engage one or more targets relatoivelt quickly by bringing her unengaged flank to bear on the target and then steaming away to reload the tubes.  This would be more fitting than firing a salvo of fish and then having to steam off to reload or just be out of torpedoes and forced into a gun fight she is not well suited to be involved with only six main guns.

Also more fish means a higher probability of hitting with more spreads in the water to cover your enemies possible evasive manuevers.

==============================================

Many thanks to Ithreko for a great idea. This will be something that might go BOOM but it is so much what I have in mind with my current thinking on Dutch tactics that it actually fits my fleet even with the lousy gun characteristics. The max on that hull is 12 x 610mm  torpedo tubes, though.

The reloads are what makes the cruisers such boom toys.

Well going BOOM is a side effect of many torpedo cruisers...are the big torpedoes oxygen driven or something not quite so....flammable?

1918: (+8) 20000@26, 15000@30, 10000@35, 300kg warhead (+2) 3t weight, 24"

It won't be until 1926-1928 that the oxygen fish would be ready. At the moment they are either electrics (slow speed setting=wetheater) or large wetheaters.

That battleship looks like having a block coefficient of 0.75 or so, it should look somewhat sleeker.

Ahoj!
I like the Macht ... some minor issues (diesel, no. of AA guns) aside.
