Maybe if the ex-ASW guys had a bit more respect for LJs obvious knowledge about the capabilities of UAS, and LJ had a big more respect for the complexities of airborne ASW (many of which haven't been mentioned and can't be discussed on an open forum) then this (academic) discussion might make smoother progress....
Why did I say academic? Because whether it be a manned platform, or a UAS, this government,
AND THE NEXT, won't have any spare cash in the defence budget to spend on airborne ASW assets (other than RN helos).
So discuss, as passionately as you like, the academic values of manned vs unmanned airborne ASW!! But don't hold your breath.
ASUW, as has already been discussed, and I think generally agreed, could pretty much be done by UAS tomorrow!
