Coast guns

[KWorld]

Guys,

As far as coast guns go, myself, I preferred the system from last summer, where we bought the guns (and turrets, if used) using SS to get the weights to the table-based system we currently have.  It encouraged countries to use their national gun sizes, where the current system really doesn't, and it better supported the use of guns smaller than 6".  Guns mounted in the heavy concrete casemates common in the 1920s would pay an additional cost, as would disappearing mountings, while the parapet mountings common in the 1860s would be the cheapest and would pay just the cost of the guns (since the other costs are nominal, just earth-moving and some concrete or brick-laying to build the parapet and the emplacement).

What's the opinion of the group?

You mean this system?

Coast Defense

Coast defense batteries may be constructed. Guns may be emplaced in turrets, in casemates, or in pits on disappearing carriages. The costs differ for each option according to the table below. The standard emplacement of a coastal gun can be expected to withstand damage from a projectile fired from a gun of similar caliber, with a few exceptions.

In addition, coast defense guns may be provided with 'extra defense' or 'massive defense' emplacements. This has the effect of adding to the amount of punishment that emplacement can take. Extra defense means that a gun can successfully withstand a hit from a typical projectile from the next size up gun in the table below. Massive defense means that the gun can successfully withstand nearly any foreseeable enemy projectile. In both cases, the weapons themselves must be exposed, and are still subject to damage or destruction by a direct hit.

Turrets have the advantage over casemates of a much wider field of fire. Disappearing carriages have a nearly unlimited field of fire similar to turrets, but remain open to plunging fire from above, no matter what protection has bee provided for them.

To calculate the costs of coast defense batteries, add up the costs in $ and BP of each gun equipping that battery, plus the costs for extra or massive defense, again per gun. Upkeep percentages are the same as those used for naval ships. The values in the table are provided for reference.

For example, a 4x15" casemate battery with extra defense provided would cost:

0.75 * 4 = $3 and 3BP, plus 2 * 4 = $8 and 8BP for extra defense. The total is $11 and 11 BP.

Maintenance for the same battery would be:
Mobilized: $11 / 40 = $0.275 per half
Active: $11 / 80 = $0.1375
Reserve: $11 / 400 = $0.0275

It is assumed that any coastal battery includes necessary communications and fire control systems.

Coast defense guns 8.01" and larger require 6 months to construct the gun, and 6 months to install it, for a total of 1 year for project completion. Guns below 8.01" require 3 months to construct the gun, and 3 months to install it, for a total of 6 months for project completion.

Guns or whole turrets may be reused in coast defense batteries, in which case the cost of that battery is reduced.

When reusing just guns themselves:
Turreted Coast defense battery, reduce cost in $ and BP by 1/6 compared to that built with a new gun.
Casement Coast defense battery, reduce cost in $ and BP by 1/3 compared to that built with a new gun.
Disappearing Carriage Battery, reduce cost in $ and BP by 2/3 compared to that built with a new gun.

Re-using a turret with it's guns guns:
Turreted coast defense battery, reduce cost in $ and BP by 1/2 compared to that of building a new turret and guns.

These cost adjustments are applied before the cost for extra or massive defense is added.

Except include parapet as a new type. 

[KWorld]

That's the current system, which should get parapet mounts as a new type if we continue to use it.


The other system that I was referring to was one from the aborted previous incarnation of Navalism, where we bought coast guns using SS.  I'll have to see if I can spot the remnants...... ah, here it is:

I think the current system works, if only because it allows us the different types of defenses without having to sim it all in SS3.

True, though it doesn't really cover coast defence mortars very well.  I'm OK with keeping it, just wanted to see other people's opinions.

My personal opinion on coast defense mortars are that coast defense mortars are basically disappearing rifles behind Massive Defenses. 

[Darman]

And my recommendation for parapet-protected guns is that they be half the cost of disappearing mount guns.  For a rough estimate for budgeting purposes that is what I'm currently doing.

My personal opinion on coast defense mortars are that coast defense mortars are basically disappearing rifles behind Massive Defenses.

That drastically over-states their cost, though.  Coast-defense mortars should be cheaper than higher-velocity weapons, not more expensive.

[Darman]

Create a new category then?

It's a possibility, just annoying to have to do.

[KWorld]

And my recommendation for parapet-protected guns is that they be half the cost of disappearing mount guns.  For a rough estimate for budgeting purposes that is what I'm currently doing.

What I've come up with so far is that parapet mounts are 2/3 as expensive as disappearing guns.

[Darman]

okay

[Guinness]

We never got around to adding coast defense mortars before because they were largely obsolete at the time in the game we were at, and I had trouble finding solid specifications for them and examples other than the US 12" mortars. I don't remember looking too terribly hard, however.

The US was definitely a fan of them, going from the 10" and 13" blackpowder seacoast mortars of the 1840s that were used during the US Civil War to the 12" mortars that were quite prominent in the defences of the 1890s and 1900s.  Armstrong produced 28cm guns for Italy, the Japanese producing guns to the same design themselves (these were the guns that destroyed the Russian fleet bottled up in Port Arthur).  They're really quite similar to the short-barrelled siege howitzers of the day as well, like the 42cm Big Bertha, etc.
