Tony, you are obviously correct. Hmm, could've sworn I read in Av Week about 2-d nozzles that could deploy reverse thrust on this thing a few years ago. Maybe it was a different program...

Anyway, Tony, shame on both of us for not just giving Rob this link. There's a whole program description from beginning to current - and don't miss the galley of pics.
