Abstract : An improved store launching device is disclosed wherein the inside of a standard sonobuoy launch container is modified to accept, and properly dispense, only one smaller and lighter store. A positioning ring is fitted securely onto the inner walls a preselected distance from the discharge end to provide a seat for a perforated obturator. A slotted pressure relief ring, with the edge adjacent the obturator having a biased cut of a predetermined angle therein, is placed adjacent the obturator and the discharge end of the container to surround the store.
