Quote from: Kaiser Kirk on April 24, 2024, 11:12:33 PMI rather expected the 300mm Razees to start a new AC race, and I think if life hadn't gotten so hectic for poor Snip, perhaps there'd be a reply that would have sparked that race.

I find the "cost" of replacing that much belt armor fairly high.
Installing the extra deck armor as a splinter 'protective' deck may be a better use of the tonnage,
as you get protection vs. bombs, and it backs up the belt.

Hmm, the rules cover going to Electric drive when changing power plants,
but not going from Electric to something else. Pretty sure the USN installed geared drives during some refits, so that should not be an issue.

The primary problem with Electric drive was apparently the wt:KW stayed roughly the same, while other methods did not.

I wasn't sure anyone would read my blathering on high cruise speed :)

There was a bit of an error on my part, for some reason it pasted a refit instead of the actual Mercury report, I've edited the post a couple up from here to show the actual Mercury-class 360mm ship.

And I agree on the armor and whatnot, which is why in my actual refits of the R-class from the late 19-teens, the only armor change is adding deck armor, and/or applique onto the main turrets which were quite a bit deficient in armor in some cases.

None of the designs involve refitting from electric drives, that last R-class 280mm razee is a redesign for new construction in 1934....the old R-class had electric drives because that was what I had to use.....the 1934 design takes advantage of the weight savings of more modern powerplant design to pack on more speed. 

And yes I saw your blathering.......I'm experimenting, can't say I'll go with it, but it's worth the experiment.

Quote from: Jefgte on April 23, 2024, 09:59:20 AMAC4 need refit too

You can not add the Torpedo bulkheads under Refurbishment
"New armor decks, external belts, and external bulges for torpedo defense (not "torpedo bulkheads") can be added.  Existing armor decks, external belts, or weapon armor can be replaced or removed (not increased)*. " 
*torpedo bulkheads not included there.

Under Reconstruction, which has different pricing, which specifically includes moving around internal ship bulkheads you can.

"Internal belts can be replaced or removed.  Torpedo Bulkheads can be added."

The Xwarg (Live Coal) Class Fast Minelayer is envisioned as a follow on to the Sahog class.

The consideration that AA rounds will have to added to the CP/SAP/AP loadout has increased the standard ammo supply from 220-250 to 330 rounds. Conceptually they expect AA engagements to be short bursts as a squadron of planes come through, not long engagements.

And something a lot more radical, taking to mind Kirk's thoughts on high cruising speed.  A return to the 11in gun style, but as it's built now it's pre-modernized.  Gone is the electric drive, and the savings go to boilers and turbines....and bringing the armor up to something adequate to fend off the relatively heavy heavy cruisers that would be this ship's natural prey.  Very High top end speed, and experimenting with both a moderately long range and a very high cruising speed.

An alternate plan for the Mercury.....drops some armor for more speed, and loses 2000 tons in the process.  Also gains two more aircraft incidentally.  The logic on the armor loss is that even 300mm of armor wasn't going to be enough to fend off the shells battlewagons are throwing around, while 240mm is enough to fend off anything up to and including a 280mm gun, which is sufficient to make them proof against all cruisers.....given they're functionally battlecruisers, this seems to check out.
