Sea Shadow, a big, black once super-secret experimental Navy stealth ship built by Lockheed Martin in 1985, which Fox News describes as "a cross between a Stealth fighter and a Batmobile" is no longer of use to the United States military and is currently in Providence, Rhode Island hoping someone buys it or puts it in a museum.
Sea Shadow is only one of two top-secret vessels that are currently being retired in Providence. The other is known as the Hughes (as in Howard Hughes) Mining Barge. It looks like a floating field house, with an arching roof and a door that is 76 feet wide and 72 feet high, according to Fox. Sea Shadow berths inside the barge, which keeps it safely hidden from spy satellites. Naturally. It was "made to escape detection on the open sea."
In this era of robotic warfare, we can only imagine the next fleet of stealth ships that will be retired by the Navy in the coming years. These will likely employ human-like consciousness and have the ability to destroy you on a whim. No museum is safe.
