vessel and preventing target vessel propulsion the net size may be optimized for target vessel capture the net being significantly larger than the target vessel is deployed over such vessel the ballistically dense rocket motors will sink upon impacting the water this causes the forward section of the harness and array to hang down in the water column as the target vessel attempts to escape the harness lines and array will then become wrapped around the vessel 39 s hull and if present tangled in the propeller this will cause the propeller to cease motion rendering the target vessel unable to continue motion the net size will advantageously be a minimum of 250 ft 76 m wide by 250 ft 76 m long and will likely have a weight of 1000 to 3000 lbs 450 to 1360 kg depending on target vessel requirements nets of this size have been successfully deployed from surface craft in distances in excess of 1500 ft 460 m exemplary material for the net is aramid fiber reinforced with a core of stainless steel cable the cable provides the net with additional toughness to resist abrasion and damage such as that caused by entanglement with a target vessel propeller the tether material may be aramid fiber or similarly reinforced aramid fiber or may be formed of a relatively elastic material the integrated launch rail system may be used to support the rocket motors prior to launch and provide for desired rocket motor path during extraction this system may provide for the adjustment of quadrant elevation and azimuth angle for required mission settings the launch rail components will advantageously be suited for long term exposure to salt air the reusable launch rail system will advantageously be provided with a complete inventory of spare.
