Sea Shadow (IX-529) was an experimental stealth ship built by Lockheed for the United States Navy to determine how a low radar profile might be achieved and to test high stability hull configurations which have been used in oceanographic ships.

Development

Sea Shadow was built in 1984 to examine the application of stealth technology on naval vessels, and was used in secret until a public debut in 1993. In addition, the ship was designed to test the use of automation to reduce crew size. The ship was created by the Defense Advanced Research Projects Agency (DARPA), the U.S. Navy and Lockheed. Sea Shadow was developed and built at Lockheed's Redwood City, California facility, inside the Hughes Mining Barge (HMB-1), which functioned as a floating drydock during construction and testing.[1]

History

Sea Shadow had a SWATH hull design. Below the water were submerged twin hulls, each with a propeller, aft stabilizer, and inboard hydrofoil. The portion of the ship above water was connected to the hulls via the two angled struts. The SWATH design helped the ship remain stable in rough water up to sea state 6 (wave height of 18 feet (5.5 m) or "very rough" sea). The shape of the superstructure was sometimes compared to the casemate of the ironclad ram {{ship|CSS|Virginia||6}} of the American Civil War.[1].

Sea Shadow had 12 bunks, one small microwave oven, a refrigerator and table. It was not intended to be mission-capable and was never commissioned, although it is listed in the Naval Vessel Register.

Sea Shadow was revealed to the public in 1993, and was housed at the San Diego Naval Station until September 2006, when it was relocated with the Hughes Mining Barge to the Suisun Bay Reserve Fleet in Benicia, California. Until 2006, Sea Shadow and the HMB-1 were maintained and operated by Lockheed Martin for the US Navy. The vessels were available for donation to a maritime museum.[1]

The USNS Impeccable and Victorious ocean surveillance ships have inherited the stabilizer and canard method to help perform their stability-sensitive intelligence collection missions.[1]

In 2006, the U.S. Navy tried to sell Sea Shadow to the highest bidder;[2][3] after the initial offering met with a lack of interest, it was listed for dismantling sale on gsaauctions.gov.[4] The US government mandated that the buyer not sail the ship and be required to scrap it.[5] The ship was finally sold in 2012.[6][7] Sea Shadow was dismantled in 2012 by Bay Ship.[8]

Legacy

Sea Shadow was the inspiration behind Elliot Carver's stealth ship in the James Bond film Tomorrow Never Dies, with the same appearance as Sea Shadow.[9]
