Ah really thanks for the correction

Perhaps that's why TLAM strike suggested that the closer the distance the more accurate the direction will be(bearing and elevation)
Also bear in mind that bow sonar could and would only detect a low frequency submarine at relatively short distance already, unlike the towed array for example. Perhaps there's a big reason why they would want a less sensitive ASW sensor on their bow instead of a sensitive ASW sensor since the first would enable them directional detection despite the shorter ASW detection distances while the later would not. Or the less sensitive bow sonar is simply because the bow sonar must handle more flow noise since it's going against the sea flow directly when the sub's moving forward. But either way I think it's safe to assume that directional detection of enemy submarine could be handled by the bow sonar sphere though in relatively short distances. Enemy submarine after all is just a facet of the threats faced by submarines whose primary preys are the surface ships afterall.
If this is true this would mean that sub trailing another sub must trail them relatively close in order to ascertain their prey cruising depth and any depth change with the bow sphere sonar. I could imagine the difficulty if the trailed sub has a towed sonar thus the only way to avoid detection when trailing sub probably is by quietening the sub so much that the enemy towed array is rendered incapable of detecting the trailing sub. A major engineering feat if true and able.
Anyway there already similar threads made on this very topic years ago. Then the submarine gurus were still well active in this forum. They made fascinating read.
