Catapults that shoot tanks that shoot machineguns.

You know the catapult they're talking about isn't new at all, right? It attaches to the nosewheel of the aircraft and zips it along the runway on the carrier to gain takeoff speed. They are usually steam powered. If you saw Top Gun, you have seen it in action. Here's a closeup of the hookup:

Actually it's a ship that fires catapults that shoot airplanes that drop bombs that shoot missiles.

Linear electric motors (IE: rail guns) are the next gen of carrier catapults. No boiler needed, recharges more quickly, variable force, less sudden acceleration.

Not necessarily. You have just as many pilots, but they sit in a room and stare at video screens instead of flying in the plane. Remotely piloted planes require no life-support stuff, but the remotely-piloted gear more than offsets that saving. Plus, it's new tech, and new tech is always super pricey. The big cost savings is in operation, because they tend to use less fuel than fighter or attack planes. Fuel is a huge percentage of your cost for military operations, especially aviation.

The only interesting thing about catapults is that the newer ones use linear electric motors, as in a rail gun, instead of steam. This makes them able to launch small UAVs, which have been too light to launch with steam catapults. Doesn't apply to the X-47B; that thing's bigger than some carrier fighters.

Obama if you really want to keep the carriers safe while cutting budget here is an idea. Bring everyone that is protecting corporate interests home.

Trillions saved,no casualties no need for additional drones or research relating to war. Sink a billion into processing sea water for drinking and use. Budget issue solved while also solving another massive issue

Think about it. If the trebuchet arm goes through its arc, and launches you from the sling at the top of its arc, you're going to be about 30-40 feet in the air, and your eventual flight would get you even higher. You could probably survive a fall that from that height into water, but it's going to hurt like hell, especially when you add in the additional velocity of being slung forward a hundred feet or so in the couple of seconds it takes to land. So, no, probably not.

hell, two banks of capacitors, one in use, one charging and recharging time would probably be a completely non-issue.
On the other hand, I wonder which is more explosive/danger to the ship. boilers or capacitor banks.

mbillips: he only interesting thing about catapults is that the newer ones use linear electric motors,



Energy storage subsystemThe induction motor requires a large amount of electric energy in just a few seconds - more than the ship's own power source can provide. EMALS' energy-storage subsystem draws power from the ship and stores it kinetically on rotors of four disk Each rotor can store more than 100 megajoules, and can be recharged within 45 seconds of a launch, faster than steam catapults.

holy CRAP

Rail guns have been something that is supposed to replace all sorts of propulsion systems in the near future.  I doubt we'll see any of them launching drones anytime soon.

Years back I saw a documentary on unmanned aircraft. They were talking with the officer in charge, he was very excited they were on the verge of programming them to dogfight. With no human body to worry about the maneuvers and G forces they can sustain are insane. Once the program was complete the drones could take off, fly to their destination, fight off attacking aricraft, deliver thier ordinance, fly home, and return the their assigned shelter. The only human input after take-off would be permission to deploy weapons. Otherwise they would be fully autonomous.

Meh, kind of puscatore compared to the Hawker Hurricanes the Brits used to launch by rocket off merchant ships in WWII. The pilots had to ditch or bail out after chasing off or shooting down the German bombers. Amazingly, out of nine combat launches, only one British pilot died.

That depends on the size of the trebuchet, obviously, it doesn't have to be 40' tall.  Maybe only 15' or 20'.  I have been cliff diving from 50', so 30'-40' at the top of the arc isn't really a concern.  Velocity could be a problem, of course, but with right arc you can lose a lot of your forward momentum.

More this:

than this:

with a max height in the 40' range.

Also, if anyone cares, here's the X47-B launching from a land-based catapult:
