The Galeras class minelayers are built to the newest torpedo-boat standards. In time of war, they are intended to lay offensive minefields in enemy waters proximal to Gran Colombia. Seventy mines are carried aft on dual rails aft, essentially precluding embarkment of torpedoes and requiring that the aft guns be superfiring to avoid unpleasant consequences related to blast effects and nearby mines.
Three units are envisaged for 1912, likely to be dispersed between the two fleets rather than operated as a squadron.
An actual torpedo-boat variant of the design is under development but not anticipated for construction in the current year.
Note that the forward gun is not superfiring, as the sim states; it was just easier than splitting the 3" battery into two separate entries. It has no significant effect on the design that I can find.

Gran Colombia will be laying down two battleships of the Furioso class in 1912. They are somewhat larger than the Triunfante class, and will carry Dutch-manufactured 35 cm guns as the main battery. A model with five triple 305 mm guns had been considered as an alternative, but it was considered less attractive at a time when other navies are introducing 35 and even 38 cm guns on their own capital ships.
When completed in late 1914, the class will replace the old Poderoso class pre-dreadnoughts in service.

Daaaaamn. If that's not the nastiest thing I've seen really planned for Navalism's oceans, then it's sure as heck in the top five.
Glad you like her. I think there are a few ships as nasty, but I'll settle for top five.
Note that I've just edited in a new SS report. I had to adjust the belt length so that the ends were fully armored and so that the main belt extended from "A" to "Y" turrets as I've drawn the ship.

I like her very much, and my own plans for battleships will be very similar. But then considering her first-rate, high-quality, accurate and hard hitting main battery the design could not fail to be excellent. 8)
Nice drawing
Powerfull BB with:

I hope to see them in the Pacific & visite them when they are amicaly at anchor in Callao.
:D :D :D
Jef ;)
They'll be sure to pay a visit.
Glad you like the drawing. I found the superstructure a little modernish, and despite suggestions from a couple of folks, never managed to improve on it to my liking.
I find them- aside from being able to thrash my Oklahoma class- utterly beautiful. The superstructure isn't too advanced, and the firepower is downright awesome.
Thank you very much.
It's not like I want them to end up shooting at the Oklahomas - but they - and Superbe, and the Rohirrim battleships - do require a response.
At President Alizandro's insistence, and to the Armada's annoyance (since it's coming out of their budget), Gran Colombia will be laying down a new presidential yacht for the use of the head of state.
Libertad is equipped to provide for luxurious transportation of the First Family, a guest and his family, and a modest number of aides and staff (seventy). There is a range of luxuries, ranging from a library to a swimming pool. The fittings are to be quite ornate and will include originals by a number of Gran Colombian artists; consequently, the ship is expected to be considerably more expensive than a modern protected cruiser.
The yacht is not armed for surface action; the machine guns are for security, but the 47mm guns are saluting pieces only. President Alizandro believes that it should not be necessary for the yacht to be armed in peacetime - and in a scenario where irregular forces might be at work, such as the pirates of Mesoamerica, a dedicated military escort would accompany the yacht.
In wartime, it is expected that the yacht would function as a hospital or casualty evacuation ship. The Presidential and Libertador Suites would be converted to operating theatres, the dining/conference room to a ward, and the smaller cabins would be utilized as required. This is not just a matter of making the most of the yacht; President Alizandro also reckons that the donation of the presidential yacht for this purpose would help his stature amongst the common military man, plus the yacht would be relatively safe in this protected non-combat role.

Since there is much talk of destroyers, I'll post the GC design for H2/12. Seakeeping is certainly not great, but the other features are satisfactory.
Of note, the class will be the first to mount depth charges, a dozen being reckoned as more than enough to sink a submarine. However, you won't see them in the drawing.

How about this alternative aft turret arrangement? The #4 turret would have clear aft firing arcs at longer ranges.
(http://img.photobucket.com/albums/v79/BCRenown/Glorioso2.png)
Ahoj!
IIRC there was a lag between introduction of superfiring and actual capacity to fire above the lower turret
Also, something SS does nto take into ccount, but which the piccies show nicely - dumping the lovely L-H-L pyramid for the H-L-L arrangement makes the citadel longer.

That was my first impression as well, but after comparing with the original, I do not think that is the case (the aft turret have not been moved).
But I must say i prefere the original look... ;)
Ahoj!
Maybe you're right, and it's just a trick of the eye ...
Borys
HLL compared to LHL also decreases hull stresses (weight closer to amidships), but SS2 won't show that.
Monty! Is that really your first post here?
I hadn't considered a reverse-Mogami layout, but it's pretty as well. I was mainly going between the aft chunk of Agincourt and the look of New York. I guess my thinking with the layout I did go was (maybe) improved firing arcs forward of amidships, while keeping the turret aft.
The citadel is the same length either way, but if you compare where the barbette from "C" turret is located, my chosen layout leaves more room for machinery amidships than the HLL layout.
Welcome aboard Monty ;)
About the BB design...hmmm...
Internal disposition is not very good.
The place of the boilers is too great & the place for the turbines too short.
Remove the 3rd stack & instal ventilators for turbines with life boats in this place.
Turrets disposition is very good.
Jef ;)
I guess moving the #3 barbette 25' (assuming the scale is 1 pixel = 1 foot) further forward would cut into the machinery spaces somewhat. And, a capital ship only 593' long could ill-afford to lose any such space. I stand corrected guys and thanks a heap for the warm welcome. :-* :)
That's the scale alright.
You're welcome, and enjoy the site...just maybe go easy on the kisses...
The protected cruiser Puerta Espana was Gran Colombia's first to use turbines, and the result was...not spectacular. By modern standards, in fact, she's quite the plodding thing. Now that there are a number of newer, better, faster cruisers in service, the time is right to make some improvements to PE, specifically:
Main battery
Cost: 0.101 BP, $0.20
The 140mms are just replaced, but the four 47mm are replaced with two purpose-built 65mm AA guns. Triple torpedo carriages replace the doubles.
Since the weapons are not that old, and in decent shape, it's expected that they will be re-used in a shore battery somewhere in 1913.
Machinery
Cost: 0.955 BP, $1.91
The new machinery allows a top speed of almost 26 knots, while being small enough (lighter than the original 1905 machinery) to fit into the existing space without requiring movement of bulkheads.
The old machinery (2 x 7,000 HP and 1 x 8,000 HP) is to be re-used in some fashion where the age isn't too important - probably auxiliaries of some kind.
New miscellaneous weight
Cost: 0.150 BP, $0.15
This is, more specifically, the stuff using the miscellaneous weight: 25 t for wireless, 25 t for flag facilities, 60 t for mines, 6 t for torpedoes, and 34 t for a weight reserve.
There are no plans to re-use the twin torpedo carriages. I'm not that tight-fisted.
General refit
Cost: $0.61
She's there in the yard anyway, so what the heck.
Total Cost
1.206 BP and $2.41.

Nice modernization, but you left yourself a little hull strength.

Not worth it. Decrease coal capacity and use the ship for minelaying.
If I wanted a slow minelayer, I'd use the surviving VTE protected cruisers for the purpose.
I recognize there's a little extra hull strength left - I think the issue was that adding much more of anything would result in one of those "Magazine/Machinery spaces not fully armored" kinda warnings. At any rate, the ship does what she's supposed to, as designed.
