Also, aluminum has far less cycle life. So say a bar of steel, can take 1000kg before bending. You can essentially cycle it tens of millions of times below that deformation point without it failing. Conversely, Aluminum, work hardens and if you cycled it at 50% of it's deformation limit (not failure limit), it will eventually fail. If you wanted to stress cycle steel right around it's failure limit, you can still essentially do it millions of times before failure, aluminum you drop down to the tens of thousands if you're loading it that much. This is why airframes have flight hour limits. The aluminum skeleton has been flexed/stress too much and must go through a total overhaul/inspection/replacement.

I think what they realized is that if they used a specific type of stainless steel which gets stronger at cryogenic temperatures (like in a super chilled rocket propellant tank) then they could actually get much better strength to weight ratios than using carbon composites so even ignoring the price and workability the stainless steel was actually the logical option. However, in a use case with more normal temperatures such as a ship carbon composites are almost definitely lighter for the same strength.

worked on the port royal when i first was starting out in the shipyards. Everything above the main deck was aluminum. Sure was a sight to see when it pulled in

I served on an FFG (Oliver Hazard Perry class). The ship had to be put in dry dock to attach plates to the sides, to stop it from buckling. And then USS Stark was hit by two Exocets. One missile didn't even explode... instead its fuel set fire to the ship, doing as much damage as if it had exploded. And that's the thing: if you're attacked in an aluminium ship, you are at extreme danger of being burned to death, or being hit by the shrapnel. Even if Phalanx was able to intercept a missile, hundreds of missile fragments would still be inbound, at high speed, and would go right through aluminium.

Isn't there also _powdered_ steel used in thermite? Also, _most_ powdered materials burn? Unless I'm wrong somehow.

This does remind me of hearing about one of the great footnotes of the Falkland Islands War, when the British were using polyesther uniforms for troops, which they found out not only were prone to melting in far more conditions than wool, they also tended to result in worse burns. I've always wondered about using either heat treated steel or cold worked to save weight, both are wildly stronger than untreated material, but both suffer from serious heat vulnerability, which is a big issue in something like a ship, as the material will lose strength with exposure to heat and fail as it no longer meets he engineering requirements. I still think you could use stuff like that on an aircraft more reasonably, and it's strength is already competitive with titanium, the issue for the cold working is the dies, even diamonds stop being hard enough, while for the heat treatment it's hard to get deep heat treatment on thicker sections, which doesn't matter on aircraft at all. I also wonder about ceramics sometimes, aluminum oxide for example is extremely refractory, hard AF and exceedingly heat resistant.

My last year in the Navy (1964-1965) I was aboard the USS Atlanta (IX-304). The Navy wanted to know how an aluminum-clad warship would withstand a nuclear attack. It was to be nuclear, but The U.S. signing the nuclear atmospheric test-ban treaty did away with the nuclear atmospheric test, so the tests were done with 100-ton hemispheres of TNT - melted out of WWII bombs and placed on the shore of the Hawaiian uninhabited island of Kahoolawe. We had aluminum deck houses, torpedo tubes, radar antennas, and other aluminun structures, all above the main deck - and we were on the third deck down - and sealed in. During the tests, it was like being in a huge steel barrel that was struck by a big hammer. You could say that we got a bang out of it. At least we didn't get any exposure to nuclear radiation. The tests were conducted by EG&G.

Yeah, no one paid any attention to the aluminum framed class 8 trucks that destroyed themselves. Nor did they pay attention to the years and years of building superstructures. The only way to make aluminum tough is to use a hell of a lot of it. In fact if you use high grade steels you can make a far lighter structure when seeking fracture resistance. (Think 5 series vs. CrMo). So team dumb dumb (most admirals are great politicians, reasonable strategiest, and piss poor technocrats) thought hey the fast ferry tech is awesome, let's use that. Not thinking: This is a warship, not a fuel efficiency optimization experiment. What kills me is you can make a warship basically impervious to most modern antiship missles by armor and hull shaping. A semi-submersible platform is far better for radar and makes a harpoon, silkworm, or Exocet simply not work. You can shape and armor the above surface / shallow surface significant to deflect blast and do the same far below the waterline for torpedoes. With bubblers you can dramatically reduce hull drag and sound signatures. Turbines are small and make a hell of a lot of power. You can run hotel loads off of a plutonium thermogenerator small like NR-1. You can run propulsion off of a high efficiency, high reliability diesel (think Napier deltic or equivalent in terms of performance). There's lots and lots of solutions that yield a 30+ knot vessel capable of the LCS mission with much greater survivability. Plus a vessel meant to pierce waves inherently is much better in rough conditions. Something is just off in the decision making.

Aside form scuttling, very few ships are sunk without onboard fires. The ones that come close are usually because of cracks developing from explosive shock and in many cases accentuated by fatigue from previous service in rough seas. Historically, aluminum deck houses have been compromised by destroyers firing their own guns. This problem was "solved" by upgrading the aft gun mount to a helicopter platform.

I thought a lot of the issues around aluminium in the Falkands./RN were about crew survivability (i.e. the ability for the crew to survive and get off the ship) rather than ship survivability (i.e. the ability for damage crontolto keep the ship afloat/operational).

It's important to recognise that survivability of the ship is different than survivability of the crew in the context of the loss of the ship. Aluminium produces incredible toxins that spread incredibly fast in fire that will also spread incredibly fast.
