I think LAMPS II was supposed to be a "super LAMPS" for the H-2, but it was decided that the equipment was too big/heavy; thus the decision to adapt the H-60 and thus the LAMPS III.
But it gets better WRT Fire Scout: FFG-7s were originally designed to carry DASH; the design was too far along when DASH was cancelled to change it. Thus the UH-2 (which up til that point was the Navy utility helo) was modified into the SH-2 because it would fit in the same footprint. So it's sorta ironic that the technology has finally come along far enough to fly drone helos off OHPs, as originally intended.
But it's not really full-circle...again, FS isn't robo-LAMPS, not intended to be, and there's no interest in making it into one (let alone any funding). There are some guys looking into what else FS can do to support maritime missions, but that's about it. It's an ISR platform, and there are currently places and missions where it's advantageous to fly your ISR platform off a ship. '
Look, I just did this mission for a full deployment. Believe me, you really wouldn't want to do it in a -60.
