Sea Shadow (IX-529)
ADDPMP029The Northrop (later Northrop Grumman) B-2 Spirit, also known as the Stealth Bomber, is an American heavy strategic bomber, featuring low observable stealth technology designed for penetrating dense anti-aircraft defenses; it is a flying wing design with a crew of two. The bomber can deploy both conventional and thermonuclear weapons, such as up to eighty 500-pound class (230 kg) Mk 82 JDAM Global Positioning System-guided bombs, or sixteen 2,400-pound (1,100 kg) B83 nuclear bombs. The B-2 is the only acknowledged aircraft that can carry large air-to-surface standoff weapons in a stealth configuration.

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 that have been used in oceanographic ships.
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.
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.
