Abstract : This patent is for a Tactical Expendable Device (TED) adapted to be ejected into the water from a variety of launch platforms. It achieves and remains substantially stationary at a predetermined operating depth for a predetermined time interval or sinks at a predetermined rate for sensing acoustic signals and transmitting such signals to the launch platform through a long, small diameter connecting cable such as a fiber optic filament. The TED system comprises the TED cannister, a long connecting cable, deployment means on the launch platform including a launch tube with integral dereeler, a buffer and onboard signal processing/display equipment. The TED cannister further comprises a sensing element, a buffer, a power source and a dereeling device.
