"Sea Fighter" The X-Craft was designed to demonstrate to the US and other navies the versatility of a very high speed, high payload capability vessel which can cross oceans quickly, and operate in shallow coastal waters on missions which include mine counter measures and antisubmarine warfare. The Littoral Surface Craft-Experimental LSC(X) was developed by the Office of Naval Research and christened Fast Sea Frame Sea Fighter (FSF 1) on 5 February 2005. The X-Craft transformational program is a high-speed, aluminum catamaran consisting of an advanced hull geometry, designed to give the craft speeds of 50 knots or more. Initially, she will be used by ONR for purposes of hydrodynamic experimentation and as a test bed for Hull, Mechanical, and Electrical (HME) concepts for the Navy's new class of warship, Littoral Combat Ship (LCS). X-Craft is the first vessel that the Navy has designed specifically as a “sea frame,” decoupling hull, mechanical and electrical (HM&E) systems from the mission packages and allowing for a true “plug and fight” mission module capability. Mission flexibility will be demonstrated through interchangeable “mission modules” (standard twenty-foot containers) housed in the X-Craft’s large mission bay. The mission bay will hold up to twelve containers, each with its own dedicated service panel, permitting rapid reconfiguration of the vessel to support a variety of potential missions including battle force protection, mine countermeasures, anti-submarine warfare, amphibious assault support, and logistics/humanitarian support.
