Re the littoral combat ship, congress wanted it to cost less so they looked at all the features and said “cut this, cut this, cut this” and one of the things they cut to reduce cost was the galvanic corrosion protection system. For reference, the lcs is made of steel and aluminium, and when you have two different metals in contact with eachother in an electrolyte (such as sea water) you get a voltage differential between the two that causes oxidation (and hence rusting) exceedingly quickly. As such, by removing the galvanic corrosion system to save 10 grands with of copper wire and a transformer, they instead made the hull rust through in barely a year. Designing things by committee strikes again!

haveblue posted:They literally entombed it in concrete which was sufficient to remove the immediate danger to the rest of the plant. The entombing was done hastily and was never meant to be a permanent solution, so it was eventually replaced with a more sound and long-lasting tomb that will allow the site to be gradually cleaned up inside it. Here's a German (sorry) documentary on the decommissioning and deconstruction of a German NPP, and it's so German, it actually hurts. https://www.youtube.com/watch?v=UpUjNayFJvM Really soon, you start to comprehend the scale of the effort underway, despite looking fairly inconspicuous. Every single loving gram and scrap of debris has to be weighed and scanned for radiation countless times, same thing for every single tool for cutting / chiseling / deconstructing (which usually have to be scrapped themselves afterwards, because you cannot reuse even the most "mildly-hot" materials), and the monitoring, red-tape, and paperwork behind it all is absolutely staggering. Man, I'm glad Germany bailed on nuclear power so expediently after Fukushima, what a great example to all the other nations that will surely follow suit in short order

Just lol at the people who think building that rusting ship was an exercise in anything but shifting tax dollars to mates. A ship falling apart that fast is great business because then you need a new ship.

You forgot the best bit, the engineering report about the steel engine mounts and aluminium superstructure simply said “the ship is disintegrating at a molecular level”. That’s engineer for “gently caress you”.

I would like to point out that galvanic corrosion was first observed in warships, in the eighteenth century. Pre‐industrial people could have told Austal they were making a mistake.

It's not even just the hull, it's also mainly a critical component of the propulsion system, the aluminum water jet outlets. I was reading that they fail in such a way that high-pressure seawater gets pumped directly into what's supposed to be a dry cavity between hulls, the same area the magnetic cloaking coils are, and coincidentally also the area the galvanic mitigation loops (?? on terminology) would be, had they been ordered

Australian shipbuilders, American contractors, funding and labor. I heard a story that the engines sat exposed on the dock for like 3 months because they were not ready to install them yet, that is how they rusted as they were supposed to be stored in a climate controlled warehouse.

I really don't think you can blame this on Congress. The LCS procurement was seriously hosed up (and the class is pretty much useless), but Congress didn't go in and say "Oh, yeah, delete this subsystem that keeps the impeller housings from disintegrating." https://apps.dtic.mil/dtic/tr/fulltext/u2/a601555.pdf

Like, I can't even think of one that's supposed to be going well? Because along with the F35, that could also be describing the Zumwalt-class, the Gerald Ford aircraft carrier, the next generation artillery projects, the laser projects, the rail guns, ballistic missile defense, etc. etc. etc.

That reminds me of a work story from last year. I used to do theatre tech work at my university for beer money. We were doing a walkthrough with the fire marshal to show off the demos for the pyrotechnics for an upcoming show. Everything went great until we got to the spark curtain demo hanging in the air. The batten was set, the pyro guy hit the button, and the shower went off. Straight up into the catwalks. The wrong direction. Turns out "this end up" was not the same as "direction of flames" on this particular pyro. Pyro guy was pissed at himself, fire marshal chuckled, and we fixed it for the show. That's my funny pyro story.

luxury handset posted:i like the navy's laser because it's controlled with what looks like an xbox controller in front of some cut rate gaming setup They actually DID replace some equipment with off the shelf xbox controllers. Periscope equipment on subs and the Army laser program: https://gizmodo.com/why-the-navy-plans-to-use-12-year-old-xbox-360-controll-1818511278 They have enough buttons and the pullaway cords mean they're easy to hotswap if something happens. They're not milspec at all, but the custom controller boxes they were using to run periscopes in submarines ran 38k A PIECE. They can just stock up on a dozen spares. Or go steal them from somebody's bunk or the rec room.

The other side of that coin is that you can hand one to a new recruit and 99% of them will pick it up in seconds. Right stick controls the aiming, left stick controls movement, assign zoom buttons, use the triggers for sensitivity modifiers, DONE. A half sheet of paper detailing what each button does taped to the wall and that's an entire training manual that's sitting in the desk drawer collecting dust.
