The thrust of the EMALS can be modulated during the stroke to accelerate the aircraft gradually and apply the thrust throughout the catapult’s travel. This force profile is much less damaging to the airframes during launch. The use of electricity also reduces the chances of a “cold cat shot” where the energy applied is reduced by the loss of steam pressure.
Tests like this have been done since the British invented the catapult take-off around the end of WW II.
At the other end of the ship is also another new technology, the Advanced Arresting Gear, that uses water braking and electric motors to stop the aircraft.
I'm sure they're well aware. If I had to guess, they're testing initial thrust (from stationary to moving) against the variety of different weights to correspond to the aircraft they intend to eventually launch from the deck and that they'll test more aerodynamically appropriate projectiles as they progress in testing. Just MHO.
Tesla, only thing they good for.
The owners of the 4.5 million Tesla cars that have been sold might disagree with you. No, I don't own one myself.
Just means there are a lot of fools in the world. Sad
I would like to launch a few of our politicians out of Washington with that.
Goodbye steam catapults, hello electromagnetic catapults.
EMALS for the win.

Erm.
Aircraft =/= car
They are doing it wrong.
It's pretty cool that they skip when they hit the water.

I agree, but was reacting at a basic level.
Also, what kind of airplane weighs 80,000 lbs? That's a lot of payload.
Interestingly enough my Kenworth fully loaded weighs 80,000lbs….. it would almost be worth the ride.
