VESSEL OVERVIEW A landing craft type vessel built of all welded steel, the MV PRUDHOE BAY features a flat deck, flat bottom, raked bow and stern, twin propellers and twin rudders. These have more modern sensors, a 76mm AK-176 on the bow and two 30mm AK-630 CIWS on the stern. This facility is sometimes used to control aircraft speed in steep descents, or to taxi backwards when on the ground. The triple screw, twin skeg hull form is the most viable answer for the amphibious support craft to succeed in the military’s operational envelope. For many vessels, there are several possibilities to upgrade or improve an existing installation. The patented SLV was a result of focusing on possible answers to the operational problems of conventional landing craft. The ship is highly automated to reduce manning. Speaking at a defense industry event in Maryland in mid-October 2019, Capt.

These forces include environmental forces, propulsion, and steering. The Navy’s budget proposal for 2021 asks Congress for $30 million to begin developing the “next-generation medium amphibious ship design.” The stern-lander appears to be the leading candidate. J.R. Hill, the amphibious warfare branch head within the Navy’s expeditionary warfare directorate, said the Marine Corps will endorse adding a new small ship type. David Axe serves as Defense Editor of the National Interest. This new propulsion hydraulic turbine, which is installed inside the ship's hull, either in the center or the stern, that is to say in the engine room, is turned by a motor, be it diesel, electric, or steam, and spins at much higher revolutions than the conventional propeller, used in … “[H]owever, the SLV design has overcome the primary problems associated with conventional landing craft, including: poor head sea capability due to bluff bow ramp, dramatically reducing speed; poor visibility due to bow ramp; crew discomfort and fatigue due to location of accommodation directly above machinery spaces; inadequate power available when de-beaching due to propellers working inefficiently astern, and the need to overcome the forefoot suction effect.”. This helps ship owners to achieve immediate and significant cost reduction and increased reliability of their stern tube systems. Our more over 40 years of successful tenure working for marine industry with utmost commitment is a significant proof in this context.
