Ok, so the purpose of LFA is then mainly to protect the fleet from very quiet subs?
I mean you can hardly 'surprise' a sub, when you ping like hell the whole time (and I think LFA would then be online the whole time to fulfill its role?)
So, what I did not fully get so far: Is the time of big passive sonar arrays (ship platforms) over - and then also system like Prairie Maske (sorry did not found the correct spelling, I mean the system which influences the bubbles so that you get a noise reduction) - because what sense does it make to reduce your noise profile if your main sensor is active?
