Hull structure made of composite material that includes a hull with high thickness “single skin” monocoque plating without reinforcements and an internal stiffening structure (1) formed by a deck (2), two opposing transverse bulkheads (3) and more cradle-shaped load-bearing elements (5) to support components or machinery intended to be housed on board said hull structure. Advantageously, the above-mentioned cradle-shaped load-bearing elements (5) are supported at the respective internal portions of said opposite transverse bulkheads (3) only at their opposite head ends (5b).

Described is a system for neutralising underwater explosive devices including an apparatus for identifying a naval mine, a source for emitting an acoustic signal for signalling the position of the naval mine, a first underwater vehicle designed to place the source for emitting an acoustic signal close to the naval mine, a measurement apparatus designed to determine a first distance between the source of emission of an acoustic signal and the naval mine.

An underwater disruptor comprises a water tight chamber formed by a modified housing, a modified breech, and a modified backplate sealed together by a plurality of O-rings. The underwater disruptor is configured to discharge a firing pin to shoot a water bullet from the modified barrel at a specific underwater explosive threat responsive to receiving a fire command from a remote operator. The water bullet is formed from water ejected from the barrel due to the discharge. The underwater ROV physically hosts the underwater disruptor and is configured to provide video feedback during underwater travel remotely to the specific underwater explosive and to activate shooting of the water bullet responsive to the fire command.

An underwater vehicle provided with a sonar for detecting underwater objects, the sonar being a sonar whose angular coverage in elevation is comprised between 45 and 240 degrees, is oriented towards the surface when the underwater vehicle is in the detection phase of an underwater object and whose angular coverage in bearing is less than 10 degrees to obtain measurements in a plane, all the measurements of a plane being obtained in one emission/reception cycle, the sonar allowing the detection of underwater objects located at a depth less than that of the underwater vehicle.

Mine neutralization provides for radio control of a small boat having associated therewith: a projection mounted onto the boat and pointing forward; a primary magnet; a housing holding the primary magnet and joined at the front end of the projection; a fluid-dynamically shaped explosive device detachably attached underneath the boat; at least one secondary magnet affixed to the explosive device; and, a rope or cable tautly connected at its upper end to the primary magnet and at its lower end to the explosive device. The boat journeys near a floating mine to bring about magnetic interaction between the primary magnet and the mine. The primary magnet magnetically attaches to the mine, and a pulling force is exerted on the explosive device. The explosive device detaches from the boat, moves toward the mine, and magnetically attaches (via at least one secondary magnet) to the mine.

A mine countermeasure device for disabling an undersea mine, and underwater transport, and methods therefor. The mine countermeasure device operates to mask, cancel or neutralise (detonate) the undersea mine. The mine countermeasure device is deployed, together with a plurality of other mine countermeasure devices from an underwater transport, for example autonomously. The underwater transport preferably carries out a scan of an area known to be mined, in order to identify undersea mines. The underwater transport is capable of autonomous operation over the horizon to deliver plurality of mine countermeasure devices. The mine countermeasure device targets particular sensors on the undersea mines.
