Shouldn't such small device have higher low frequency limit that big submarine hull sonars ? Same for torpedo passive seekers...

They were in use after I left, so I don't know.

Long Range ASW Unmanned Undersea Vehicles (UUV)
A torpedo-like sensor/tagger with extended range, a UUV is operated remotely or autonomously to detect and tag submarines, perhaps with remote command & control. Operating autonomously for lengthy periods, UUVs would require high efficiency propulsion, maneuverability, sensors, stealth, data processing, and connectivity. Multiple UUVs would operate simultaneously in probable submarine operating areas, searching and assessing the environment. Collected data would be communicated at regular intervals or continuously.
