Looks okay, but what's with the 1917 date?

3

Wednesday, August 5th 2009, 8:29pm

...whoops.
I knew I was forgetting to change something from the basic date I was using...

Also, as a note, the propulsion plan is two 1,000hp diesels on the outer shafts, with a 500hp coal-driven center shaft for auxiliary/emergency propulsion.

If it were me, I'd switch off to all diesel and use a geared drive. I'm extremely unfond of three-shaft designs - the only time I've ever put together a three-shaft design was on an icebreaker, with 1 shaft for reversing power. The beam's still narrow enough that I'd prefer two shafts. You're not putting out enough speed or SHP to even remotely bother a ship with twin shafts.

Hm, true.
However the Admiralty insists on a "station-keeping emergency powerplant" capable of propelling the ship at 5 knots. The Design Office figures that it might as well define "Emergency" as "in the event of kerosene being unavailable being able to burn abundantly available coal..."
...or wood...
...or the crew's dirty laundry...

...and, thus, a 150-hp steam engine was installed on a centre shaft.

It might be noted that I've upsized the design slightly; in order to fit with the roles intended, the extra size was necessary.

Maybe the Admiralty should consider adding a windmill to turn an electrical generator to run the shaft? :D

Or you could rig it like a galleon, and put giant red crosses on it, and slap a big tall stern on it with a window gallery...

Heh, well, since your seaboat rating is only marginal, it can't be speed...

You've got 86' beam and *ten meter wide* bulges...

Trim is not 50 so you must have played with it in design, but that Steadiness of 100 is rather much. I'm guessing that it's set to 70 (or under) on whatever the "real" version of the ship is.

Therefore...

Like the ammo for a twin 18.1" or single 21" gun? I'll have to Springsharp it to tell for certain, but given the above clues, it's the obvious answer.

Actually, it's set to 98. Gun platform steadiness is the #1 consideration of the Stab/Steady/Seaboat triangle on this ship.

So then build a 95m dock and construct it in that. We added those since you were last here, though I think Brazil and Chile are the only countries who have yet taken advantage of building them. Even with a 70m dock you didn't even use most of it.

Part of the rationale was to help small powers who couldn't afford to spend 1 IP to lengthen a slip, but might be able to manage .5 IP to lengthen it a little bit less. A country like, say, the Philippines could piece together a type 2.5 slip to design cruisers of longer than 557 feet while still leaving the Type 3s open for other construction.

Regarding the ship design itself, I'm not sure I see the benefit of building such an unbalanced ship. True, the 18.1" guns can punch through loads of stuff, but at almost any range those guns can *hit*, any 8-inch gunned cruiser can shoot back and penetrate your armour. The rate of fire for an 8" gun is three to four times as quick, too, meaning more chances of hitting, more shells to permit fall-spotting, and so on. Against a battleship, there's no range she can't be impaled by a 14" shell, and you don't have the speed to hang off at range and let those eighteen-inchers do their best work, nor the armour to resist getting shot at.

I won't say 'it won't work' though - because it will, particularly in the Philippine labyrinth. I just think another more balanced design will work a lot better. If it were me, I'd stick with the 320mm guns, make 2x2 turrets, and see about an 18-knot hull with a heavier deck armour - say 4-5", to try to shrug off some of the hits you're going to take. That might result in an even larger ship, though.

If I were planning how to defeat this ship, I would build more aircraft carriers and just send planes to hunt it down. She's too slow to avoid trouble, too thin-skinned to stop a dibo, and lacks a good AA suite to start with. At best, you're looking to take out more planes when her magazines go up!

This remains one of my favorite CDS vessels. It's a brutishly big CDS, almost more of a second-class battleship, and I like it. The South African coast defense ships, particularly the Gungnir, are also very solid CDS vessels, too.

I'm a bit puzzled by the ship as well: monitors strike me as vessels to use in support of ground troops, when you control the sea around them so the monitors aren't quickly run down by hostile cruisers/destroyers and sunk. But does the Phillipines need such a specialized vessel, especially as it keeps growing?

If gunfire support is the assigned goal, there are already numerous small, well-armed, better-protected, and generally all around superior vessels in the Philippine Navy which can take on that role. Marinduque, the Dagupans, even Jomalig.

But I think the goal of this ship isn't to actually do anything - it's a Prestige Ship:

Well, I need to build something with Big Honkin' Guns. :P

The secondary idea here is fire support of amphibious landings, actually. If these ships get into a tangle with enemy ships, something has gone dreadfully wrong.

Of course, considering who the new El Presidente is, 'bigger is better' will be the order of the day... 8)

I think there maybe a confusion between Monitor and Coastal Defence Ship here.

As a CDS it is flawed but those guns need to be taken into account. Chances of scoring a hit are slim but even a CA captain will wince before closing in. Should Japan supply radar RF equipment those guns could be used from much further out and with better accuracy.

As a monitor to support the Army or to bombard enemy positions or territory (I'm thinking QE at Galipoli) those guns would put Kaboomicus Maximus out of range to any counter-fire from land. Put a CAP of fighters over her and its not so easy to disable her without tying up resources and effort.
