A submersible vessel comprises a hull. The hull contains a plurality of subsystems. The subsystems comprise a sensor subsystem configured to sense potential target information regarding a potential target, a database subsystem configured to store target characterization information, a processing subsystem coupled to the sensing subsystem and to the database subsystem, and an ordnance subsystem. The processing subsystem is configured to process the potential target information according to the target characterization information to confirm the potential target as being a confirmed target. The ordnance subsystem comprises an ordnance magazine configured to store ordnance. The ordnance is deployable against the confirmed target, wherein the confirmed target is an aircraft.

The problem of penetrating through nets and other objects is solved by cutting the object using various cutter systems, which include, for example a track and a moving carriage containing a cutter, a stationary carriage with a fixed or rotating arm, and/or abrasive cutters. The object is cut by a severing, slicing, or wearing action caused by a moveable blade or abrasive surface. An underwater vehicle incorporating an embodiment of the cutter system can cut a sufficiently large opening in the object to allow the vehicle to pass through.

A method of making a tubular casing for an underwater device, wherein a metal ring made of aluminum is subjected to an anodizing process that produces an insulating layer of aluminum oxide that covers it externally. The ring is coupled with a mold that defines a cylindrical surface on which the following are deposited: first layers of carbon fiber to produce a first cylindrically-shaped tubular element in carbon fiber provided with an end portion that engages a first groove of the ring; a layer of syntactic material configured to transfer radial forces; and second layers of carbon fiber to produce a second cylindrically-shaped tubular element in carbon fiber that covers the syntactic layer and is provided with an end portion that engages a first groove of the ring.
