US Navy Readying Electro-Magnetic Launch for New Carriers
Next Big Future ^ | January 13, 2009 | Brian Wang

Posted on 01/14/2009 4:36:29 PM PST by jmcenanly

Current steam catapults use about 615 kg/ 1,350 pounds of steam for each aircraft launch, which is usually delivered by piping it from the nuclear reactor. Now add the required hydraulics and oils, the water required to brake the catapult, and associated pumps, motors, and control systems. The result is a large, heavy, maintenance-intensive system that operates without feedback control; and its sudden shocks affect airframe lifespans for carrier-based aircraft.

This may be sometime into the future. the pilots who will be launched on these systems are probably playing on swings in grade school about now.

The Magnetic Technology required will help the development of electirc cars, nuclear fusion reactors, and such.

Lots of payoffs all around!

Tell us, what's the solution?

Beter not be prone to EMF attacks.

Otherwise the carrier becomes a jet parking lot.

Not that far off as the story you linked to notes. CVN-78 will be equipped with an EMALS.

For a brute-force, heavy-industrial launch system, the existing one sure is impressive.

Like having a 500-inch, supercharged, nitrous-injection drag-racer sitting on the drag strip, waiting for the light to drop.

Something just old-tech about that.

Not only EMP but this will broadcast a signal to everyone in the world that a launch is taking place.

Your statement sounds very correct to me. Steam is “quiet” and they have plenty of it. It’s free on a nuke ship.

That looks like a dead load launch in that last photo.

Yeah it’s not launching an aircraft. A “dead load” of similar weight is used for testing.

Here's a great idea. Since steam catapults have reliably launched carrier aircraft for decades, LET'S CHANGE TO SOMETHING ELSE!

It's NOT BROKE, so LET'S FIX IT!

This sounds like the infamous automated baggage handling system at Denver airport. How many tens of millions and it NEVER worked?

You are correct. They have more than one running in the US and maybe more in Europe. They reach speeds of up to 90 miles per with the magnetic propulsion on Roller coasters. This is also the same type of technology, the basis anyway, of the Mag-lev trains that have been built in various places.

If EMP is going to be a problem, then, considering the digital nature of ships these days, the cat system isn't the only system that's going to be affected.

And if they can shield or harden the other systems, they can do that to the cat as well. And I figure they've probably taken EMP into account.

1911 Browning-designed semi-automatic pistols, with modern refinements, are still the standard by which others are judged.

The modern Vulcan cannon is essentially a faster version of the old Gatling gun.

Some stuff just works and I notice all wheels are still round though the design is quite dated.

According to Obama, all iffy DOD projects will soon be coming to a halt.
This may be one of them....
There again, if the DOD can come up with a good working model, Obama in his wisdom may still can the project.
If he can pick people like Clinton, Richardson, Holder and this new guy Geithner for his administration. We'd all better look out.

So, steam catapults don't work on aircraft carriers? Why have we spent billions of dollars building the current fleet of 11 aircraft carriers, including the one just commissioned, equipped with steam catapults when there is something else far superior?

I don't design, build or maintain aircraft carriers but you apparently want to argue those who do have been doing it wrong, at great expense, for a hell of a long time. That's not much of an argument to make to me or other taxpayers of the United States.

?? You seem to be arguing that because something works, there can be nothing better.

The world is full of improvements to existing tech. It just may be that there may be a better way to catapult aircraft than steam.

Clearly, you're not an expert on the subject, so your emotional response in favor of steam catapults is puzzling.

Seems to this civilian, without all the heavy mechanical hydraulic machinery the current launch systems need, you could actually convert one or more submarines into an aircraft launch platform - the landings would probably need to be back onto a traditional carrier.

Imagine being able to pop up out of nowhere - and suddenly there are 10 F-35’s in the air.

Abd it took 45 minutes to get all three aircraft launched. That was risky surface exposure time even in WWII. Today it would be terminal.

Plus do you really want to cut a 1500 sqft rectangular hole in the pressure hull? Think any sailors would be willing to crew it? I predict an operational lifetime of one dive sequence.
