|Anybody want some top-secret seagoing vessels? The Navy has a pair it doesn't need anymore. One is called Sea Shadow. It was made to escape detection on the open sea. It looks like a floating field house, with an arching roof and a door that is 76 feet wide and 72 feet high. Sea Shadow , 160 feet long and 70 feet wide and comes with 12 bunks, a table, a microwave, a fridge, and a gigantic covered mining barge that the CIA used to keep Sea Shadow protected from satellite surveillance. Sea Shadow berths inside the barge, which keeps it safely hidden from spy satellites. The barge, by the way, is the only fully submersible dry dock ever built, making it very handy -- as it was 35 years ago -- for trying to raise a sunken nuclear-armed Soviet submarine. If It has been trying to give them away since 2006, Sea Shadow (which originally cost nearly $200 million) is going to be scrapped at the end of this year if they don't find a new owner.
