This would make an excellent ASW platform. Fill it with sona-bouys and it could hover over a hostile sub totally unaware that it was being tracked. Give the patrol aircraft a break.
Yes, good idea.
But the USN version would be four times as expensive,
carry half the payload,
have half the range,
half the speed,
and be delivered twice in the schedule, years late.
But it would be built to MILSPECs, so it would “have to be good” in half the time , right?
