A deep ocean recoverable, tethered acoustic sensor system launchable from an aircraft or ship. Upon water entry, the system separates into an upper flotation module containing a receivertransmitter, antenna and inflatable bag, and a lower flotation module containing an expandable hydrophone array, transmission cable, flotation chamber, cable disconnect means, radio transmitter and antenna, and a flashing beacon light. The lower flotation module also includes a releasable anchor assembly containing a tethering cable. Recovery of the lower flotation module is accomplished by actuation of the cable disconnect means either by a preset timer means contained within the flotation module or by remote electrical command upon cable disconnect, the anchor assembly and upper flotation module are discarded, and the lower flotation module floats to the surface for recovery. Upon surfacing a transmitter housed within the lower flotation module begins transmitting a signal beacon through an antenna, and a flashing beacon light actuates to aid in the recovery of the module by helicopter.
