ABSTRACT:
A small sonobuoy for dropping without a parachute and quickly deploying hydrophones is cylindrical and adapted to float with its axis parallel to the water. The hydrophone cable is wrapped around the housing so that the housing rotates as the cable is payed out. The antenna is also wrapped around the housing and is released after the cable is fully deployed. A retainer covering the coiled cable and the stored hydrophones is held in place by a releasable pin which is released by an electrical device activated by a sea water sensitive switch. The device heats a resistor which melts a lanyard which releases the pin.
