Ship-to-Shore-Connector - New LCAC SSC for the United States Navy

6.07.2012 of the year. A contract was signed for the creation of a full-scale head LCAC under the SSC program between the Navy and Textron Corporation. The corporation is working on the development and creation of the DKVP together with Alcoa Defense and L-3 Communications. The main purpose - a shift in service similar LCAC (DCVP). The contract amount is almost 213 million dollars. The main user is the United States MP corps.

Ship-to-Shore-Connector - New LCAC SSC for the United States Navy

According to the contract, Textron received 2012 a million dollars in 61. The headboard DKVP will be built at the New Orleans shipyard and will be handed over to the main customer in 2017. In addition to the head LCAC, 8 boats will be built on the airspace, which will begin to be delivered from 2019 year. The contract will increase to 570 million dollars. The estimated cost of one LCAC is 44 million dollars. In the future, 72 boats will be commissioned up to 2028, the contract will increase to 4 billion dollars. The company's output for full batch production - 2020 year.

Start of development of LCAC SSC - 2008 year. The TTZ on the new Ship-to-Shore-Connector program was distributed to participants in 2011. In addition to Textron, Marinette Marine, VT Halter and Boeing took part in an open competition. The alliance of companies led by Textron immediately had the best chance of obtaining a contract, but the competitors insisted on their rights, and the choice of the project developer for the new boat was delayed for a while.

The new boat is a complete analogue of the LCAC, but according to the TTZ it will have a large payload (74 tons against 60) at speeds in 35 nodes. The entire SSC program is aimed at preserving the United States of experience and possibilities of using SVP. Boats can be alerted even inside the transported recreation center with instant access to water at high speeds for delivery to the coast of paratroopers or cargo. After unloading, LCACs quickly return to receive another shipment or airborne unit for subsequent quick delivery to the shore.

LCAC, having advantages over conventional flat-bottomed boats, has one drawback - a decent cost. They remain quite expensive to maintain and operate. The second problem of landing craft on the airplanes is the payload. When disembarking a marines ashore, heavy oversized cargo, such as the M1 Abrams, is required to be brought to the coast, so new LCAC SSCs may be upgraded in the future to solve more complex problems.

The United States Navy, before developing the SSC program, conducted a study on the use of various options for delivering troops and cargo to the coast. Amphibious catamarans with lower cost, modern types of SVP were considered. The result of the research is a return to the development and updating of LCAC.

The initial plans of the SSC program are the acquisition of 80 units of SVPs, of which 8 units will be used for various tests and 72 units will be put into operation before 2029 in the United States Navy. The beginning of the release of the program for mass production - 2015 year. By 2020, the program should achieve “Initial Operational Capability” and launch the main production of the LCAC SSC.

The SSC program will include the development of modern technologies throughout the production of amphibious boats to increase productivity and reduce maintenance. The length and width of the boat will remain unchanged, and the depth of the draft will increase slightly. During the development of the SSC program, the customer (the US Navy) set the basic criteria for future boats, and the contractor (an alliance led by Textron), using the LCAC experience, began to make changes to reduce the cost of a single boat and reduce production costs. In total, more than 25 highlights were identified, changes of which would lead to the desired result. The new boat will get the 4 more powerful engine power hp 5300. against xnumx. The boat will receive an improved frame and coating. The rear screw will have 3955 blades instead of 6. The main shaft will consist of 4 segments instead of 4. In addition to high performance, they will improve the climate control system, rework the installation of equipment and antennas, and the fire protection systems will be made to meet modern requirements.

These solutions provide an opportunity to increase the combat range of the new boat 25 miles instead of 15. The combat radius of the LCAC SSC was not chosen by chance - the cost of the amphibious landing dock transport (LPD) increased to 1.7 billion dollars.

L-3 Communications will be responsible for the development of navigation systems and controls; Alcoa will be responsible for developing the hull and structures made of aluminum alloys. Major work will take place in Louisiana and New Jersey. The final assembly will take place at Textron facilities in Louisiana. The alliance plans to complete the design of the boat in 2017 year. All major new LCAC SSC systems are new or updated, many will be used for the first time.

    I do not see anything ultramodern or superior to our boat "Murena" in this LKAK.
    The air cushion landing aircraft, pr. 12061 (Murena code) was designed by the Almaz Design Bureau (TsMKB) led by Yu.M. Mokhov. It was intended for the docking chambers of large landing ships of project 11780. Since these ships were not ordered by the fleet, the program for building boats of project 12061 was curtailed, limiting the series to eight units. By design, the ship is a development of pr.1206. In contrast to the prototype, it has enlarged hull dimensions and airborne capacities, other, more advanced radio equipment and enhanced weapons. The boat can also set mines, for which it is equipped with a removable flyover. The hull of the boat is made of aluminum-magnesium panels, with bulletproof and anti-splinter armor for the wheelhouse. Murena is capable of overcoming obstacles of the “vertical wall” type with a height of up to 0,8 m, as well as going out with cargo to an unequipped shore with a slope of up to 6 °. The seaworthiness of the ship ensures its operation and use of weapons when moving on an air cushion, with sea waves up to 3 points.

    The main tactical and technical elements:
    - standard - 104,0 t;
    - full - 148,0 t;
    Main dimensions:
    - the largest - 31,3 m;
    - maximum width - 14,8 m;
    - the width of the rigid body - 12,9 m;
    - height of the flexible fence - 1,5 m;
    - draft with a full displacement of 1,1 m;
    Crew - 11 (3) people. (including officers);

    - number x type of propulsors - 2 X BB;
    - quantity X type - power of current sources of electric power - 2 x GTG - 70 kW each;
    The highest speed - 55 knots;
    Cruising range of 50 knots - 300 * or 200 ** miles;
    Autonomy in terms of provisions with a landing party - 1 day;
    Airborne capacity:
    - option 1 - one tank "PT-76";
    - option 2 - 2 “BTR-60P” or 2 “BMP-2”;
    - option 3 - 130 people;
    - anti-aircraft - 2x4 PU MANPADS "Igla" (24 SAM ammunition);

      Will the Murena MBT handle? Don't need Abrams, at least T-90.

      Yes [excrement] complete, barely lifts their tank (which is the heaviest in the world, the same [excrement]).

        So this project is already under 30 years old. It would have been complete ... indeed, South Korea would not have bought 3 pieces in 2006-2007, which, along with LKACs, are in service. By the way, the Almaz website gives information that one tank weighing up to 1 tons can be taken.
        Theoretically, the T-90 will resist.

      Our developments in terms of landing tanks from the sea and overcoming water barriers in general are, indeed, original and promising, and work in this direction was carried out actively. As for the American DKVP, in my opinion a very practical technique, not without flaws.

    The main and key device for hovercraft is a propeller or, without a difference, a propeller. It is the main mover in the longitudinal displacement vector and it also creates an air "cushion". It is not possible to use any type of turbine instead of screws. Moreover, any are all the same. The main reason is that the turbine only works in the combustion mode.
    A device has been created which increases the flow rate of air by orders of magnitude. In addition, the air flow is a reference. Maneuverability is improved due to precise control of air flows, up to reverse. Of course, reducing fuel consumption, if at all appropriate to talk about it.
    Sometimes one wants to say that it takes a thousand years to invent something in the form of a screw. And another thousand years to invent a more advanced device and understand that the former is not effective.
