That wasn't possible until the 1970s iirc.

"ASV Mk.XI had a maximum range of about 60km against ships, and in good conditions and at low altitude (2000 feet) it could detect a surfaced submarine at about 20km. But it could detect a schnorkel only in very calm seas and at distances below 8km. It gave bearings with an accuracy of about 2 degrees."
