Spanish Navy

[Logi]

If a matter of <1/64" of an inch of drop can be bad for a .30 caliber rifle barrel at 300 yards, then I'd hate to know what a foot might do to a naval rifle at 5 miles!  Also, as it is an inconsistent and inherent problem of manufacturing that tolerances will never work out as they should, each case being different makes it harder to adjust for each individual case. I would imagine that the scale might mitigate the severity, but it cannot eliminate or marginalize it.

Yes, that is quite true. However- as I pointed out originally, barrel droop becomes a huge problem when naval gun ranges reach the excess of 3000 yds (what I meant by period battle ranges). The droop of a 1ft on a 15"/32 would result in a downward angle of roughly 1.4 degrees. 1 degree is roughly 100 yds on a 13.5"/30 so I think we can expect a range drop of ~150 yds. At 1000 yds, that is 15% of the range -  at 2000 yds, that is ofc half at 7.5% of the range. I had thought because of the close ranges, drop and firing higher could be alleviated by free-board +superstructure height of the ship - although it seems to be simply 0.6 degrees height for a 10 ft freeboard at 1000 yds. -So I probably did underestimate it.

A ship- especially one involved in gunfire support- can also expect to fire MANY more rounds than a ship in a naval battle... a 3 hour bombardment would not be unheard of in preparation for a major operation. Finally, any navy that will have a relatively small fleet at sea (like all our nations) has to consider readiness. Re-gunning a capital ship isn't like swapping out the barrel on a SAW. You take that ship out of action for weeks... and if you only have 10 battleline units, then you are already at 90% strength for a couple of months- without considering other problems which might manifest.

You are correct, I'm trying to look for an alternative to the 15"/32. I ran into all these problems as I was looking for a gun that could penetrate the 18" Harvey Nickel-Steel mounted on my pre-dreads. It is a very tall order and that's why I had to resort to very large calibers like 15" (I wanted to stay at 13.5") to avoid lengthening barrel caliber.

Essentially, I think we're placing importance on two opposing schools of thought here.

I agree that seems to be the case.

Even further shaved weight of IAB Gloria:

- Shaved main belt, main battery armor, 8" face armor, 4.7" face armor.
- Switched to open barbette from main battery to save weight
- Increased 8" other armor, increased upper belt armor.
- Added 15" torpedoes

- Shaved additional 1,676 from normal displacement (3,568 in total), 1,802 tons from light displacement (3,837 in total)

Note: Main belt is resistant to all gunfire from the ship. Upper belt is resistant to all but the 12"/20s. All batteries are resistant to their own fire. (Previously they were resistant to +5-10 cal versions of their guns)

Super shaved weight version- how's this for light:

- Removed one of the 12"/20 turrets
- Shaved conning tower armor
- Shaved 4 rounds from 12"/20 guns, 10 rounds from 8"/25 guns.

- Shaved additional 2,170 tons from normal displacement (5,738 total), 1,958 tons from light displacement (5,795 total)

Note: As before, Main belt is still resistant to all gunfire from the ship. Upper belt is resistant to all but the 12"/20s. All batteries are resistant to their own fire. Conning tower is no resistant to all but 12"/20 gun fire.

[Jefgte]

IMO, for IAB Gloria-1877
Increase beam
decrease BC
Increase freeboard
Increase deck armor.


Jef ;)

[Carthaginian]

For a coastal BB... the two-turret version looks pretty much right, though Jef is right in that the deck armor needs increasing.

Right now you have side armor that will stop a 12" shell, but the deck is barely proof against a pissed-off 4 year old with a screwdriver.

[Logi]

The idea was that since the main belt was to protect against it's largest caliber (and thus pretty much all other shells of the time), having a deck was only necessary as a splinter deck. That was why the deck was only 0.5", enough for splinter but not much more. Increased to 1", but further increases really will result in too much weight added.

The reason, I had low beam and freeboard was that they drained composite strength (on the order of ~700 tons normal). Had to slightly shorter hull length to keep weight increase from going into 800 tons normal.

However, here is the version with the corrections- (+660 tons normal, +601 tons light)

I did a similar ship, then deleated most of the smaller guns as it was pointed out to me that there realy wasnt anywhere to put them or any need for them.  not a bad ship though.

Mostly because I did a model of this version...

Enlarged version of the 5,980 ton Normal design with three twin 12"/20s. It looks like it fits, but that's by pushing all the weapons closer together than other ships in historical period. The result is very limited arcs of full broadsides.

For example: The three twin 12"/30 have an arc of ~50 degrees for a broadside on each side because of the aft guns.
Only half of the casemate 4.7"s can fire past 30 degrees beyond full broadside on forward or aft.
The 8"/25s have roughly 120 degrees arcs that they can fire at (30 degrees beyond full broadside).

It's just Google Sketchup Free, so all the dimensions in the model are correct.  ;)
