Sea Shadow is one of the most exciting floating structures ever built. This experimental machine was supposed to check how much you can hide against the enemy radars. Its construction was commissioned to Lockheed Martin under the supervision of DARPA and US Navy.

The construction of the Sea Shadow unit in practice has tested the possibility of solving the problems of the American leadership at the turn of the 1970s and 1980s with the use of the stealth technology of the F-117 Nighthawk, or possibly the greatest automation of ship handling to reduce the crew needed to a minimum. It also tested how the new hull type will be tested in the ocean.

Completed in 1984, the ship, until 1993, remained a strictly secret project. He has never been officially accepted to service, despite the presence in the US Navy’s records. By the end of his days he remained an experimental unit that was not intended to carry out any mission.

Sea Shadow had nearly 600 tons of displacement, a length of 50 meters, and its engine was able to disperse the unit to 14 knots (26 km / h). The crew was only ten seamen. Its main problem was the very small space reserved for the crew. On board we could find 12 places on bunk beds, microwave, small fridge and a table.
