Abstract : An apparatus for ejecting a tethered underwater device, such as a communications instrument package, from a naval vessel such a submarine is taught. The system incorporates a relatively long hydraulically operated launch tube thereby permitting slow acceleration of the device to achieve the desired muzzle velocity resulting in a reduced acoustic pressure wave upon launch.
