SEA SHADOW


Description

Sea Shadow is a test craft developed under a combined program by the Advanced Research Projects Agency (ARPA), the Navy, and Lockheed Martin Missiles and Space Company. The Sea Shadow program was begun in the mid-1980s. Its purpose is to explore a variety of new technologies for surface ships, including ship control, structures, automation for reduced manning, seakeeping and signature control. In 1993-1994, the craft was revealed to the public and underwent daylight testing. Since 1994, Sea Shadow has been maintained in a lay-up status and is currently homeported at Naval Station San Diego. In anticipation of conducting future ship research and development testing, the U.S. Navy reactivated the Sea Shadow craft in early 1999. Sea Shadow will support risk reduction for future surface ship platforms such as DD 21, the Navy's 21st Century Land Attack Destroyer. The platform will allow the Navy to explore and test, in a realistic at-sea environment, important DD 21 advanced information and automation technologies that support reduced manning and ship survivability.
