Ok, I've heard of some strange things going on sale on Ebay, but this SUBMARINE, armed with a McDonnell Douglas Sub Harpoon ship-to-ship missile system, six 21 inch bow torpedo tubes taking the Gould Mk 48 Mod 4 dual purpose wire-guided torpedo, and 20 ship-to-ship missiles and torpedoes TAKES THE CAKE!!
Going for a low, low price of 4.9million.
Good news, that's AUD, so it's only about 2.5 million US...though you'd have to find a crew to get it to America...
