Which puts a lot of stress on the aircraft. This new system looks to eliminate that by a smoother, linear acceleration over time. Essentially, top speed coming a bit later than right f'in now.
The key, as you say, will be dependability.
It was probably Marketing hog wash, but I believed it.
So does electricity. That's why it's used for the drive wheels of locomotives.
ow will it affectimplanted pacemakers?
I don’t fully agree with that. Electric motor and coil applications have hysteresis.. as some have suggested, that might actually be beneficial (vs steam) in the case of an aircraft carrier catapult. I could see that.
In trains, the reaction time of the motors is not only not that important, but each axle or truck can be powered with a smaller, individual motor/geartrain that is much easier to reverse and speed-control than with a bell-crank or *any* mechanical arrangement, and the same motors can generate dynamic braking. They are also dozens of times easier to maintain.
That isn’t confirmed by anybody, outside of SOME Russian Media.
We do know that the Navy hasn’t said yeah or nay about it, although they did complain about being over-flown by Russian aircraft. If it really did happen, we won’t know about it for 50 years.
That would have been true of steam as well?
Seems if claims of more linear acceleration for EMALS is true, it is closer to being capable of lauch without damage.
I didn’t think of that but probably not in a good way.
The steam systems are messy, require a lot of maintenance, etc. Just the steam leaking out combined with all the grease gets all over the place.
Steam shots have a lot of power at the beginning of the stroke. I thought EMALS was supposed to be a smoother acceleration. No way the Navy can operate without external tanks. Can’t be done.

That was my point. Maybe they launch with empty tanks to minimize stress and then tank up to fill? Not a carrier guy, dunno about their flight ops.
If that happened then I assume the fact that you had a steam catapault wouldn't make any difference. If the electronics are fried in the ship and the airplanes then there isn't anything to launch anyway.
And why electric cars accelerate so well
This is an extremely dangerous and troubling incident. Almost as troubling is the news blackout of its occurrence.
We live in very dangerous times.
So I’m guessing that mean less guys to support catapult ops now?
So a full fuel pod weighs more than a rack 500 pound bombs?
Uh no.
Well, hopefully you won’t need guys schlepping barrels of grease around. The thing about most of the flight deck divisions is that you have a fight ops component to your job, and a division maintenance component to your job. Even with less maintenance you still need enough guys to run the cat and button it up (fast) when the last bird gets launched.
The drops on the F-18 E/F are 3k.
Not enough gas airborne to do that. Gotta have a full bag to go. Drops have to be dry to trap.
