Sea Shadow to be Scrapped

DARPA's Sea Shadow, a ship built in 1983 to 1984 to test new naval technologies, is being scrapped.

The ship is best known as a testbed for stealth technology -- it was designed by the same Lockheed folks who built the Stealth fighter -- but it was also used to test the stability of the SWATH hull design (which turned out to work very well) and new automation systems that reduced the necessary crew to a handful. (It has only 12 bunks.)
