The present invention relates broadly to an unmanned surface vessel (10) comprising a hull (12), an underwater appendage (14), a winch (16), and a cable or rope (18). The cable or rope (18) is at its distal end attached to a remote device (20) with the cable or rope (18) arranged to cooperate with the winch (16) to be deployed and retrieved from the vessel (10) via operation of the winch (16). The underwater appendage is in the form of a keel including a cavity (22) designed to partly locate the winch (16).

A non-lethal naval vessel interdiction weapon is provided. The non-lethal naval vessel interdiction weapon includes a hydrodynamic hull, guidance and delivery systems housed in the hydrodynamic hull with the delivery system being controllable by the guidance system to drive a naval vessel impeding payload toward a target and a deployment system. The deployment system is configured to prepare the hydrodynamic hull for payload deployment and to deploy the naval vessel impeding payload toward the target following hull preparation.

A rigid ballistic-resistant composite includes large denier per filament (dpf) yarns. The yarns are held in place by a resin to form a rigid composite panel with improved ballistic performance. The large dpf yarns may be selected from aromatic heterocyclic co-polyamide fibers, polyester-polyarylate fibers, high modulus polypropylene (HMPP) fibers, ultra high molecular weight polyethylene (UHMWPE) fibers, poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibers, poly-diimidazo pyridinylene (dihydroxy) phenylene (PIPD) fibers, carbon fibers, and polyolefin fibers.
