Congratulations to LJ for finding more non-existent stuff to support his case. You have also missed the development of GPS guided sonobuoys which was/is being looked at for the accuracy required when dropping buoys from med/high altitude. I quite liked the PHASE buoy by SeaLandAire but noticed that their buoy still requires manual selection of channel, cable length and life - obviously quite simple and easy in a manned platform but a little more tricky in a UAV, without complete redesign of the buoys. ISTR that the unit price of a standard LOFAR buoy was in the order of £5-600, so it won't take much to start making these very expensive bits of kit.
There seems to be a lot of 'stuff' that's going to need a redesign for it work on a ASW UAV. Now for an 80% solution, with no need to redesign anything, I give you:
