An expendable underwater vehicle for use in training naval forces in anti-submarine warfare in ocean waters, including shallow waters, is between about three to five feet in length and about five inches in diameter, and it includes various improvements which make successful operations in shallow ocean waters, and improved operation in all ocean waters, possible. The improvements include a one-piece nose cup which allows the expendable underwater vehicle to be air launched into shallow water, a scuttle plug which allows water to fill the expendable underwater vehicle after the vehicle is expended and drops to the bottom of the ocean, and rudders and elevators of increased surface area which improve controllability of the vehicle in the water.

A sonobuoy having a terminal weight and sensor for deployment beneath the surface of the water after the buoy has been launched from an aircraft and impacted the water. A circuit assembly and antenna for processing output from the sensor and for transmitting a signal is provided. A cable for connecting the sensor and circuit assembly is also included. A housing for the sonobuoy is a blow molded seamless thermoplastic shell which surrounds the circuit assembly.
