Lockheed Martin and the office of naval research are demonstrating the SLICE vessel, an advanced type of (small waterplane area twin hull) configuration. The SLICE prototype, introduced in 1997, has four underwater pods with propellers on the forward pods. The vessel is 104 FT long, with a 55 foot wide beam. Lockheed Martin designed the advanced technology demonstration vessel, built by Nichols Brothers Shipyards and Pacific Marine & Supply Company, LTD. A cooperative agreement with the ONR to validate the SLICE technology provided the impetus for this effort. The 180 ton 105 FT prototype Slice vessel cost nearly 15 million for research and development. The SLICE ship has completed all sea tests and has met or exceeded all performance goals.
