I might be wrong but the last time it was brought up someone mentioned that Landing Ships of any variety are capable of unloading all of their cargo in one trip without any penalties.

Correct. It's important because in an atoll, you have to Shock Attack every day you unload, so it's important to A. unload in as few days as possible and B. unload as much stuff as possible in the one day you're unloading.

What's the soonest Grey can get the Ki-84, Ki-100, and N1K-J into service? Those are really the only Japanese planes that are really suited for fighting late war US aircraft.

This isn't really the place for it, but those ships are a clusterfuck in a bunch of ways. The manufacturer is currently being sued because they had workers use giant circular saws to cut metal even the though the saw manufacturer says specifically not to do that. It has led to a bunch of people losing fingers/hands/arms, but is faster than doing it the right way.

Any time you see big corrosion problems post launch or a lot of injuries on the job, it's a clear sign of a corner-cutting and poorly-managed company. Sacrificial anodes are nothing new, and the grand fix Austal announced for their third ship was to actually use them.

Does the game distinguish between nightfighters and regular fighters?

As you would expect from a game this grognardy, it does! The USA gets a handful of squadrons flying planes like the P-61 Black Widow, P-70 Havoc, and night fighter variants of the Hellcat, Corsair, and Tigercat. The Brits have Fireflys, Beaufighters, and Mosquitos fill the role. All of these carry some form of radar. Unlike ships, I actually don't see separate day/night experience or skill listings for air groups, but it wouldn't surprise me if the game has it modeled in some obscure stat tucked away somewhere. I've never actually used them since an AI Japan tends to give up on night bombing (at least in any amount that matters) long before night fighters come online.

Speaking of those, it absolutely blows my mind that shipbuilders are still running face first into problems with galvanic corrosion. Within ten years of the launch of the first iron-hulled warship (HMS Warrior), designs were already being pioneered to avoid the issue. HMS Inconstant used a clever system of wood furring to keep the copper and iron separate - in 1868. 150 years later, we apparently have forgotten these lessons.

Did some digging since I used to work at a corrosion center.


The hulls are aluminum. Apparently some shipbuilding doof forgot that there aren't any salt water proof aluminum alloys.

Are they too far into the project to change it or is this gonna a comedy of errors until the first ship disintegrates on deployment?

They'll most likely have to do a very strict paint inspection schedule and *probably* use some of the really heavy duty epoxy based paints.

Aluminum hulls have other challenges for warships, not least of which is that they apparently have an unfortunate tendency to melt and catch fire at significantly lower temperatures than steel. This has significant downsides e.g. when hit with an Exocet.

Needing to keep the ship painted is probably nothing new; my understanding is that modern vessels rely on specialized biocidal anti-fouling paints to keep sea life from colonizing below the waterline. It's the galvanic corrosion that's a real problem, as an aluminum-steel interface turns the steel into a sacrificial anode for the aluminum. Admittedly, missing a spot of anti-fouling paint doesn't normally seek out any non-isolated steel in the ship and rust it!

One can Google "destroyed m2a2 bradley" and see a bunch of photos of their burnt aluminium hulls having swallowed their steel turrets. It's mostly fine when you're literally a leap away from the exit. Probably not cool if you're trapped inside a burning warship.

But hey, at least they're not making them out of magnesium!

You joke but I've seen work on magnesium, studying behavior under high rate impacts, with the eventual goal of using it for light weight structural elements in certain vehicles. It does have its advantages - it's very, very light.

Maybe if the heat was removed from the magnesium hull faster than it can build up then there wouldn't be a potential problem with flammability? What if there was a system of pipes carrying liquid oxygen within the hull to deal with that?

If I remember highschool chem correctly, pure magnesium violently reacts with air, water, really anything not a noble gas. Keeping it cool wouldn't do much, I think.

I totally want to watch what would happen if you dropped a ship-sized mass of magnesium in the ocean though. From a very safe distance.

Magnesium's actually ok at normal conditions. It's commonly used for various mechanical parts. Heat it enough in the presence of oxygen, though, and you're going to get a great lightshow.

You're probably thinking of lithium, which is usually kept in oil and really doesn't like water. As in, it will catch fire if you put it in water.

We should have quick-acting water mist fire suppression systems in case it does catch fire so that the fire can be dealt with quickly!

Oh yeah I'm thinking lithium. Magnesium gets a crust of magnesium oxide on the outer layer when exposed to air that keeps the rest from exploding without adding more energy, iirc.

Mobile (pronouced mo-bee-all) is a fairly large city in Alabama. I assume that's what the ship is named after.

It is on Mobile bay, which connects to the gulf of mexico, and is currently the production site for the controversial Independence class littoral combat ships.

Mobile Bay was also the site of a significant naval battle in the American civil war most famous for the union commanders order to sail through a minefield saying, "drat the torpedoes! Full speed ahead!"

For bonus trivia: both commanders of that battle have facilities named after them on the campus of the naval academy in Annapolis.

Not least because Exocets tend to do damage by bringing a whole bunch of fuel on board at high speed. Their fuses are terrible and detonate the warhead less than half the time, but smacking a bunch of combustible liquid wrapped with steel into a ship at high speed does a lot of damage. Stark and Sheffield both took hits without an explosion and lost a fire main when hot wreckage physically crashed through the pipes. The Stark survived because she had redundancy where HMS Sheffield didn't.

Thanks.

The ability to improve the charts is severely limited by the requirement to use Google Sheets to generate the charts. There's a lot more that can be done, but it'll only be useful to Grey if he's up for using some third-party charting software. That's probably asking too much.

The main improvement was already made in that link - putting japanese always as some shade of red and allies as some shade of blue, and putting the text in the labels into the same order (for example "allied AI and japanese AI", as opposed to "AI allied and japanese AI") but the thread apparently rejected these changes as "confusing" so I dunno, guys.

The red/blue graph was an improvement in theory, but the decision to fade the AI instead of fading the historical values kinda sabotaged its readability, and it could have used a finer resolution on the grid lines.

Sheffield sank under tow in a gale 6 days after being hit, in calm waters like Persian Gulf she may well have floated indefinitely.

Stark was in a friendly port within 24 hours and the counter flooding she required could well have proven ineffective in the South Atlantic.

Thank you. I have vague memories of the Sheffield lasting a while, but 6 days is a credit to the RN.

Yeah, there are a lot of boring plane runs that do no or minimal damage, but overall they are much quicker than "having" to document a bunch of carrier strikes.
