“You know, the new thing is magnets. So instead of using hydraulic that can be hit by lightning and it’s fine. You take a little glass of water, you drop it on magnets, I don’t know what’s going to happen,” Trump said.

He thinks that magnets can be foiled by water.

fahfahfahfah@lemmy.billiam.net · 40 pts · 298d (7 replies)

I think what’s he’s getting confused about is that they’re using electromagnets, which the circuitry of could certainly be damaged by water.

I suspect someone at some point communicated some kind of potential problem the navy could be having, and he just went “magnets + water = bad, got it”. Which is what I think the real point should be here. It’s not so much that the president is confused about how magnets work, its more that someone at some point mentioned some kind of existing or potential situation and he is just spewing it back out without really understanding it.

Like basically the president of the fucking United States is not capable of understanding someone telling him that electromagnets can be damaged by water and/or is unable to communicate that basic concept.

Nobody tell him that fighter jets sink in the water, he'll have all the carriers decommissioned because "Planes don't go on water. Why are we sending airplanes into the ocean, they'll just sink!"

Yeah, see, you don't need to worry about planes sinking in the water if you don't take them out in the water. Melt all the carriers down and make shitty branded watches out of them to sell to dopes for way too much money.

The article has a translation

The elderly president was talking about the magnetic catapults used to launch planes from the latest Navy super carriers, the USS Gerald R. Ford class, and the electromagnetic elevators used to move weaponry to the flight deck. Both systems double the speed with which planes can be armed and launched but slowed the delivery and commissioning

If you remember the news a few years back there were all sorts of delays and problems caused by switching from hydraulics to magnetic/electrical. It’s probably a vague memory of more complexity than he can handle. A sane president would have had someone with expertise go over his speech

It was the first time so as long as all the issues have been worked out and the next one is smoother, we’re good

I honestly don’t remember what specific problems they had during development but it’s easy to believe dealing with harsh environment at sea for long periods was one of them.

“You know, the new thing is magnets. So instead of using hydraulic that can be hit by lightning and it’s fine. You take a little glass of water, you drop it on magnets, I don’t know what’s going to happen,” Trump said.

“So, you know, the elevators come up in the new carriers—I think I’m going to change it, by the way—they have magnets. Every tractor has hydraulic, every excavator, every excavating machine of any kind has hydraulic. But somebody decided to use magnets.”

The 79-year-old president then stumbled over his words and failed to complete a coherent sentence before moving on and asking the watching troops whether they preferred hydraulics or magnets.

Trump then called out to a “top-ranking general” in the crowd for his opinion before continuing his tirade against the 2,000-year-old technology.

Saltwater does in fact aggressively corrode neodymium magnets. About as fast as a piece of raw iron. On top of that, the saltwater can induce currents in magnetic systems that can wreak havoc.

Pay attention to what he's actually suggesting - replacing our extremely advanced magnetic launch system with hydronics. They would have way more parts, fail more catastrophically, and would not be able to launch nearly as much weight

They would have way more parts, fail more catastrophically

This remains to be seen. In fact, the opposite is proving true.

https://maritime-executive.com/article/report-carrier-uss-ford-s-electromagnetic-systems-still-need-work

USS Ford's launch and recovery gear are electromagnetically actuated, a departure from the steam-operated Nimitz-class carriers. The new designs were developed and installed because they promised longer intervals between maintenance and higher sortie generation rates. Though the Navy remains upbeat about Ford's capabilities, these gains have proven elusive. "The reliability of CVN 78 catapults, arresting gear, and jet blast deflectors (JBDs) continues to have an adverse effect on sortie generation and flight operations efficiency," noted DOT&E in an annual report released in mid-January. "The ongoing reliability problems with these critical subsystems remains the primary risk to the successful completion of CVN 78 [initial operational testing and evaluation]."

The carrier's Advanced Arresting Gear (AAG) has similar challenges. The AAG is supposed to cycle 16,500 times between failures, but in recent testing it has broken down after roughly 450 cycles.

Belowdecks, the Ford's Advanced Weapons Elevator (AWE) elevator system remains a source of trouble. During a weapons onload in September, the lower stage elevators performed more quickly than those on a Nimitz-class carrier, DOT&E said; however, 109 elevator failures were reported out of about 20,000 elevator dispatches. "AWE system reliability will be critical as the Navy develops standard procedures for moving ordnance from magazines to the flight deck," noted DOT&E.

https://www.forbes.com/sites/craighooper/2022/10/14/in-a-first-deployment-test-uss-ford-fails-to-beat-nimitz-class-benchmarks/

In a first ordnance-handling test, the advanced weapons elevators on the USS Gerald R. Ford (CVN 78), America’s new, $13.3 billion supercarrier, offered little to no meaningful improvement over the legacy elevator systems aboard America’s venerable $5 billion Nimitz class carriers.

Crew claimed they “were able to run ammo downstairs in the magazines much quicker because we were able to put extra weight on the elevator, able to run it down quicker, which means you have to run those cycles a lot less.” That sounds great, but unbiased analysis of the Ford’s performance during the carrier’s initial two-and-a-half day ammunition onload cycle suggests the Navy has yet to take full advantage of Ford’s eleven faster and stronger elevators. Put bluntly, all the high-tech electromagnetic elevators aboard the USS Ford failed to translate into a faster ordnance onload cycle. It calls a primary pillar of the Ford’s business case—that new ammunition handling techniques would yield vast performance benefits and make the ship less vulnerable—into question.

Those articles are from 2022, when they were still shaking things out in real world usage. Since then the bugs have been slowly but consistently ironed out. It happens every time with defense development these days.

They're looking to expand use of the system, because it is just all around better. There's fewer parts, it's faster, smaller, and lighter. That means smaller aircraft carriers

This is a non issue, Trump just doesn't like "electric". And yeah, I'm sure he heard about problems in development and latched onto that in his first term, but really it's about rare earth magnets from China... Which these systems use, along with just about everything else these days

Not to mention, these systems are smaller and lighter ... is it even possible to retrofit a steam launch system on the all electric carriers built around this?

If you actually read those articles you just linked, you'll find the titles are click bait. The program has massive cost overruns, just like the F35. And similarly, it's had issues, but the F35 is an incredibly advanced aircraft now

But the navy expects to hit the promised performance metrics by 2030. They're moving forward with the program, even considering expanding it into ground based systems

The navy can indeed fix their electronic catapults, I don't know if that last one is AI or what, but the entire article is a huge puff piece about the advantages of the ship

🚢 The USS Gerald R. Ford is the world’s largest and most technologically advanced aircraft carrier, powered by nuclear reactors.

💡 Featuring the groundbreaking Electromagnetic Aircraft Launch System (EMALS), it enhances sortie rates and minimizes airframe stress.
🌍 As a key element of U.S. naval strategy, it plays a significant role in global power projection and deterrence efforts.
🛠 Despite facing construction challenges and budget overruns, it remains adaptable to future technologies like advanced drones.

And another piece of the business insider article

The inclusion of the elevators and EMALS was paired with overall ship layout changes as well.

This relates to my other point... Is it even possible to retrofit a steam system on the Ford and Kennedy?

President Donald Trump has previously been critical of both the catapults and the weapons elevators on the Ford, expressing concern about the use of magnets in the advanced technology.

The Navy officials who testified before Congress Tuesday said the "Navy and shipbuilder HII-NNS are hyper-focused on a CVN 79 delivery plan that results in the fastest path to a combat ready CVN, crew, and air wing."

So yeah. There's been problems, the budget is out of control, but the tech is only improving

If only there was something that could be done to prevent the corrosion, like coating them or using them inside a sealed mechanism. It’s not trumps job to tell engineers who are infinitely more intelligent than him how to do their job.

Giving rare earth magnets a waterproof coating is nothing new. They are still extremely susceptible to corrosion, especially in seawater applications.

Salt water corrodes nearly everything. It's the salt.

Why would you give this man the benefit of the doubt at this point?

It doesn't really matter what scientific information has been given about magnets, we see before us what his brain turned it into.

It actually does matter when you have an entire thread of people decrying Trump's supposed lack of understanding of magnets - while simultaneously pushing completely incorrect ideas about magents and laying bare their own lack of understanding of magnets.

Especially annoying when you can do one single Google search and read a plethora of sources that explain in great scientific detail just how susceptible magnets are to water - especially in seawater applications.

You might read the article where that line about dropping a glass of water on a magnet and he doesn't know what will happen is just one example of a long pattern of his complaining about magnets (and sorry to disappoint you but drop a glass of water on a magnet and nothing will happen).

I suspect the whole ranting about magnets relates to the trade war with China which is by far our main source of rare earth materials including for rare earth magnets, and he seems of generalize them to all magnets. But the point is he says he's going to sign an EO that they can't use the magnetic elevators on aircraft carriers because of his mindset about magnets. Sure, I guess if the ship sank, there could be damage to the magnets in the new elevators, but that wouldn't exactly be the biggest problem at that point.

You are one dense mfer. Maybe even denser than Trump.

omg. trump said "drop a glass of water on it and I don't know what'll happen"--as if the brief amount of time a glass of water ran over the magnet would ruin it. He didn't say soak it in water or keep it wet for a long period of time. Obviously metal rusts over time if not kept dry. You're grasping at straws trying to defend trump.
