What kind of military vehicle would Elfstone be?

(My human is spending way too much time on Online Quizzes. Can't you tell?)
We watched Elfstone and the Big Ferocious Bit of String on the living room carpet. There could only be one answer to that question:
HARRIER JUMP JET.

Me? Based on when I lurk in the tall grasses unseen, probably a stealth something or other. It's classified.
