Based on a variant of the SWATH hull design, known as "SLICE," Sea Slice is characterized by four teardrop-shaped submerged hulls—double the number seen on most previous designs. The design reduces waves and drag, which allows a SWATH vessel to "...operate at higher speeds while retaining their characteristic low motions in a seaway".[2] Designed for operation in the same area as, and to mount similar armament to, a littoral combat ship-type corvette,[3] the planned weapon options included the Millennium Gun and the NetFires System, intended to launch Lockheed's (now cancelled) Loitering Attack Munition.

Sea Slice was withdrawn from Navy service and made available for purchase for civilian use,[4] and purchased by Danish company, Advanced Offshore Solutions ApS, for conversion to a wind farm support vessel.[5][6]
