    Abstract: Systems and methods for underwater descent rate reduction are provided. In one embodiment, a method for underwater descent rate reduction for an underwater delivery vehicle is provided. The method comprises: opening a first valve based on a first hydrostatic pressure to permit water to flow into a first chamber of a hydrostatic pressure driven piston assembly; developing a pressure differential across a piston head separating the first chamber from a second chamber of the hydrostatic pressure driven piston assembly; pushing the piston head into the second chamber to extend a piston rod from the hydrostatic pressure driven piston assembly; and pivoting a deflecting flap downward into a direction of vehicle descent as the piston rod extends.

    Abstract: An underwater missile for use against submerged submarines has a missile housing with a magnetic contact surface (2) at a foremost end portion intended to contact a submerged submarine. The magnetic contact surface is provided by two magnets (2',2") located in adjacency and with reversed magnetic polarity. A magnetically operated switching means (5) is positioned adjacent to the magnetic leakage field of the magnets, and is arranged to be operated when the leakage field is increased by means of a metallic object located within the magnetic field of the magnets. The operation of the switching means first detonates a small propellant charge (6) to impose a force to cause complete adherence between the magnetic contact surface of the missile and the outer surface of a contacted submarine, and then detonates a main explosive charge (7) intended to penetrate the submarine.

    Abstract: An explosive device contains a water-reactive material that ignites upon exposure to water. The water-reactive material ignites a water-activated fuse that has a predetermined burn rate and length. The predetermined burn rate and length allows the device to sink to a desired depth before exploding. Hence, the device explodes after a desired period of time and/or at a desired depth. Defense against underwater swimmers is an advantageous feature of embodiments of the disclosure. The device can use a forty millimeter (40 mm) form factor, which permits launch of the device from convention grenade launchers.

    Abstract: An underwater grenade and a method for using an underwater grenade. A depth activated, hand emplaced ordnance utilizing safe and arm technology to address underwater threats (such as enemy swimmers) while providing a safe interface with personnel. The grenade is armed after a sequence of events have occurred including reaching a desired depth and a desired passage of time. Failure of any of the events to occur will cause the grenade to be rendered safe.
