No, unfortunately it was classified. I don’t even recall the level, though it
certainly wasn’t all that high.

Do you have any citations for that one?
Thanks.

DARPA developed a really slick PDE that runs on hydrogen, and is printed on a
3D printer in plastic. It’s amazingly simple, readily scalable, high
performance… but unfortunately, classified. The thrust to weight ratio is
spectacular, by the way. That’s one of the best features of a PDE. This one
also doesn’t pulsate.
