Sea Shadow (IX-529) is an experimental stealth ship built by Lockheed for the United States Navy. Sea Shadow was built in 1985 and used in secret but normal service until her public debut in 1993, to examine the application of stealth technology on naval vessels. In addition, the ship was designed to test the use of automation to enable the reduction of crew size. Sea Shadow can contain 12 people. The radars cant’ spot it and looking from the sky it looks like just like a shadow.
