    Many commentators contend that the Littoral Combat Ship will fill a void in America’s Naval Warfare policy position.  It will move rapidly to distant shores, provide in close fire support, limited aviation support, and be capable of inserting, supporting and extracting special operations personnel.  Problem is, many consider it too lightly armed (the Israelis want one but will add weapon systems to their ships), has too small a crew and provides no upgrade over existing ships.  In steps the JHSV, that the Navy recently contracted with Austal USA for 10 ships.

    Joint High Speed Vessel (JHSV)

    The JHSV is capable of transporting troops and their equipment, supporting humanitarian relief efforts, operating in shallow waters and reaching speeds in excess of 35 knots fully loaded. The vessels will be a joint-use platform between the United States Army and Navy.

    The JHSV accomplishes every mission that the LCS is capable with the exception of fire support.  In many ways that mission is better performed by other platforms and the US’ orientation toward soft power exercises (especially in South America) will be the ultimate proving ground for vessels of this type.  Its high transit speed makes it very enticing as a rapid transport for the Army’s Air Assault Expeditionary Force, Stryker Brigades, and Marine Expeditionary Units. Instead of a piecemeal arrival of forces, the JHSV will allow complete unit insertion for whatever the need may be-either humanitarian assistance or preventative war operations.
