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 at Lockheed's
Redwood City, California ,
facility, inside the
Hughes Mining Barge
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
The T-AGOS 19-and-23-class oceanographic ships have inherited the stabilizer and canard method to help perform their stability-sensitive surveillance missions.
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
Hughes Mining Barge
In 2006, the U.S. Navy tried to sell Sea Shadow to the highest bidder; after the initial offering met with a lack of interest, it was listed for dismantling sale on gsaauctions.gov. The US government mandated that the buyer not sail the ship and be required to scrap it. The ship was finally sold in 2012. Sea Shadow was dismantled in 2012 by Bay Ship.
