If it comes to ripping there engines out to replace them with lower footprint models, I will do it. They would get some more comprehensive work done given the need for drydocking however.

Partially reminds me of the real-world methods to get round the Washington Treaty where magazines were designed for more shells than they actually had racks for so the standard tonnage reported was less than it would be in wartime with full racks fitted. So the question is how big is the magazine as designed? Well, perhaps take the baseline SS report before you tinker with anything else and add to the main ammo rounds until the hull strength dips below 0.99. Calibrate backwards so it stays within the 1.00. You might get a few extra rounds in and IMVHO that would by a rule of thumb that the physical size of the magazine hasn't altered too much (magazine weight might not be a good enough indicator since extra rounds = extra weight so of course it will weigh more regardless of area).

I admit this problem creeps into my mind everytime I do a refit that changes the armament. Generally if I switch to a lower calibre gun I assume the magazine can hold a few more rounds with new racks (which have to be fitted when any calibre is changed regardless of the rules in a practical sense), generally if its the same calibre I assume the same, although my recent single gun to twin gun DD conversions go to not quite a 50/50 split per gun but slightly over.

Well, another factor to keep in mind with this refit is that it does remove the torpedo tubes and all associated equipment. Given that RA had set aside 48t of weight for torpedos, I think there would be additional room to shift some internal facilities around to accommodate the larger magazine. Now whether this falls under a 25% or 50% job is up for debate (tho a 50% job would also be giving them new engines as well, freeing up more space).

Now whether this falls under a 25% or 50% job is up for debate (tho a 50% job would also be giving them new engines as well, freeing up more space).

It is unclear to me whether anyone is advocating that this is a 50% refit rather than a 25% job. Rocky asked the question whether the changes to magazines involved barbette alterations (which would be the operative concern) but I believe that your answer satisfied him. My memory on refits of magazine capacity is clearly faulty, so, at this point, I am cool with your proposal. If anyone else is not, I think they should clarify their position.

Yes, my concerns have been addressed.

Generally, I'm fine with the change being made as stated, so long as it's a weight change on a relatively minor scale.

It looks like the rise in weight will be ~9 metric tons per barrel for the projectiles. The propellant probably doubles that. So in this case, you're adding about 144 tons of shells to the design.

I definitely feel this is at least a 25% job, but I don't think it needs to be a 50% job. I've done similar changes to some of my own ships, but most of them were already receiving 50% rebuilds.

I'm fine with 25% but surely adding 1,600 shells must require some increase in magazine space?
Extending a magazine sounds easy but that means moving structural bulkheads, additional armour (if they have dedicated thicknesses to their roof and walls) etc. So by no means a small job, but probably not a 50% given that replacing machinery and boilers is an even bigger task. So 25% seems fair to me.

The first big project of the year, a major refit of Duca degli Abruzzi and Duca d'Aosta. The highlights: Improvements to the 152mm battery & increase in the ammunition count by 200 rounds. Replacement of the 47mm AA battery with modern 76mm and 37mm weaponry. Removal of torpedo and associated protection systems. Addition of modern electronics. General refurbishment. Cost: 1990.5t per ship. Time: 4.24 months (two quarters).

Shouldn't there be two superfiring turrets?

No problem, I have a real hard time proofreading my own designs and am forever missing things like this...

Fixed things. This does mean to get what I want I need to re-engine them in order to accommodate all the improvements.

A Cruiser designed for the Anti-Aircraft defense of the Marina Militare's Aircraft Carriers. Current cruisers are unable to stay with the carriers both with respect to range and raw speed. This design corrects both of those. The eventual goal is twelve of these ships, two for each Fleet Carrier. This also marks the debut of the 152mm automatic into regular service. The mount here is evolved from the prototype that has been in testing onboard the Coatit for the last 18 months.

The Main Battery is all forward? A "Mogami"-type layout fore and aft would seem to make more sense.

Also miscellaneous weight doesn't seem to add up; @ 140 tons per turret that should only come to 840 tons unless I've missed something.

Whoops, I was fiddling with something else that had all-forward and then changed my mind halfway through. 140t per turret for 6 turrets, so you are right. I've done it per-gun in the past, so I think I did that by accident.
