The Sea Wolf can carry fifty Mark 48 533-millimeter torpedoes or Harpoon anti-ship missiles, which can be launched via eight 660-millimeter torpedo tubes. (The tank’s size is meant to be future proof if the Navy adopts larger guns. The Seawolf can also use the tubes to launch Tomahawk surface attack missiles.Seawolf submarines are built entirely from higher strength HY-100 steel so they can survive a dive as deep as 490 meters.
