Trump has suggested steam catapults every year since 2017, saying digital systems are too ‘complicated’
After nearly a decade of loudly complaining about the fact that modern US aircraft carriers use electromagnetic systems to launch fighter jets instead of steam-powered catapults, Donald Trump has directed the Pentagon to redesign a new aircraft carrier to replace the modern system with the old-fashioned catapults he prefers.
Trump signed a national security memorandum on Thursday directing the defense secretary, Pete Hegseth, and the acting navy secretary, Hung Cao, to make the change he has had his heart set on since at least 2017, when he first described his idea to Time magazine.
The memorandum gives the Pentagon leaders 60 days to come up with “a plan on the required measures to replace the Electromagnetic Aircraft Launch System and Advanced Weapons Elevators with steam and hydraulic systems for the construction of” the USS Doris Miller, a Ford-class aircraft carrier, which is already two years behind schedule.

The issue between the two systems is isolation. In the old C-13 series if one track needed repair, you have to shut steam off to that track. The rest can keep going. In the EMALS there's just the one centralize power architecture, so if a track has to go down, it takes the whole thing down with it.
Few really want to return to steam. It requires a lot of the ship to house special high pressure equipment and requires more maintenance overall to keep it running. Additionally, a lot of the drones designed need the precise control that the EMALS provides to not break apart. But it's hard to point out all the various tooling that has to go on behind the scenes when one track goes down with steam, when the whole effing thing with EMALS has to go down and no launching happens for hours.
And that's ultimately what happens, the metrics that are being used are getting aircraft into the air, not overall downtime or cost to operate. And EMALS is still struggling to hit the numbers it has to hit and likely won't hit them till around 2030. Every time it goes down, every zero aircrafts it gets pulls that metric down hard.

You'd think that an electric system should allow for relatively easy isolation – isolating electric circuits from each other with breakers is hardly new technology. Is this lack of isolation a design flaw of EMALS or is there an actual physical reason why it couldn't be designed with independently powerable tracks?
gnutrino@programming.dev · 32 pts · 3d
Looks like they've already issued a contract to fix it so it would appear it's entirely possible and someone just fucked up the requirements/design first time around.

Absolutely wild that this wasn't part of the original design. I can turn off power to my stove without shutting down my whole house, but the US Navy can't independently power launch systems.
Jesus_666@lemmy.world · 12 pts · 3d
You'd think the United States would take great care when designing their main tools for global power projection. And you'd probably be right; I can imagine that countless hours were invested into determining where the parts get built and which senators get to politically benefit from that. Technological details don't really matter; at worst you can just turn flaws into lucrative followup contracts for companies in the stock portfolios of top politicians.

As the other person mentioned, they're looking to fix the "shortcomings" of the current system. Happens in government projects that corners get cut and that short-term "fixes" ends up having long-term "issues".
That said, dropping the whole thing to go back to steam because of corners being cut is a royally stupid idea. But I mean we are talking about a guy who decided to just level an entire wing of the White House before anything to replace it was actually thought out and approved.
partofthevoice@lemmy.zip · 3 pts · 3d
I’m wondering if they mean that the points of failure are overall harder to isolate? Like, I don’t know… can the steam system work if the ship looses power? That would be a level of isolation that I imagine EMALS can’t do. But then I’d wonder, what if each track had its own generator? Oh… hey, just use steam generators. Problem solved, Trump won’t tell the difference,

fullsquare@awful.systems · 1 pts · 2d
No they don't, there's still 4 units one per launcher. Most of problems you mention seems to come from energy storage system. Energy is stored in the flywheels, which requires annoying converter, so chinese variant uses giant set of supercapacitors instead which is just a bit heavier and has less problems with communications interference. Also can be split in many parts and fit in any space you have. Mostly benefit of being designed later. Zero surprises if americans figure it's better but institutional inertia keeps them using the old one

Our educational infrastructure has been systematically degraded over the past few decades, as have all our consumer protections and what few tools we’ve ever had to fight these oppressive conditions.

EM launchers do pose some issues to aircraft electronics that require a lot of redesign for shielding.
DebraBucket@lemmy.world · 2 pts · 2d
Steam launchers put significantly more stress on the aircraft, which means they have to be reinforced to support the poorly controlled initial spike in force.
Zephyr@sh.itjust.works · 1 pts · 2d
Similar forces will need to be generated to launch a jet any way. Are you saying they launch them too hard? How much softer could you be yet get the aircraft up to speed in the same distance?
DebraBucket@lemmy.world · 1 pts · 21h
Steam has a high initial peak force of 4Gs which quickly tails off (sudden peak force/acceleration, rapid drop after that) whereas EM has a peak force of 3Gs (its acceleration curve is fairly flat). That means Steam applies 33% more force, hence needed aircraft needing reinforcement to handle.
Zephyr@sh.itjust.works · 1 pts · 21h
Seems like something that could be fixed on the steam side of the equation or maybe it needs that much initial force to get up to speed. I remember the Ford was frying electronics on FA18s for a while. Maybe the steam launch is more of an issue for F35? We've been launching FA18s with steam for decades so I doubt all of a sudden it's an issue.

I did not know they used electromagnetic catapults and it somehow also does not make sense. Those carriers have a fuckton of steam left over. So instead of converting it to a battery, just to convert it back to kinetic, is not that efficient. Downside is probably increased maintenance.

Why is it waste on a nuclear aircraft carrier.
There's a giant electrical generator that has steam yes, but you have way more electricity than stream, before other benifits.
antianarchist@sopuli.xyz · 0 pts · 3d
The same reason why you have a big pillar of steam at nuclear power plants. You can only use a fraction of the steam and the rest just ends up in the atmosphere.
wholookshere@lemmy.blahaj.zone · 1 pts · 3d
You know the steam you see at a power plant is not the steam you use to generate power right?
Otherwise why don't aircraft carriers already fume steam like that?
Because the steam in a reactor is closed loop. Meaning there's just what you need, not an excess in generation.
The steam you see from a power plant is a separate cooling loop.
Aircraft carriers likely just use the more plentiful, and cooler, sea water for cooling. Meaning they don't have any excess steam to use for the catapult.
There is plenty of generated steam for other systems, but this is probably done via electric boilers, not as an excess by product of power generation.
Not an an expert by any means, but this is just using my logic and understanding from nuclear physics, from my physics degree.

Is the steam anywhere close to the launch location though? No idea how this shit works but I assume that would need all kinds of piping and valves and in the end it'll probably less efficient than converting to electricity and using that

Fair point, the heat loss during transport should not be underestimated

They don't actually. Steam catapult is operated with completely separate steam supply, and major design goal of ford class was to remove it so even if pedo in chief wanted, retrofit is physically impossible. That separate steam supply needs extra freshwater because it's not condensed and recovered. EMALS is much milder on plane and pilot because it's a big linear motor that gives constant acceleration instead of spike then decreasing like with steam. Efficiency of steam catapult is also dogshit compared to turbine + energy storage system

Oh, good to know! Thank you for explaining!

....maybe steam catapults are even less efficient? Maybe they can get better accuracy with less equipment using wires instead of a massive plumbing system? Maybe it would be way more maintenance, thus negating other efficiencies? I'm sure there are a massive amount of factors. Don't you think they need to generate electricity, anyway? Maybe adding on the launch power is negligible.
