Aerial starboard side view of the amphibious assault ship USS WASP (LHD-1) inside the deperming station crib outside Norfolk. The WASP, a new ship, is being depermed for the first time. This is a periodic requirement done by wrapping the ship in electric cables to run electrical currents back and forth until the ship has a negative polarity. This prevents the ship from detonating magnetic influence mines or torpedoes
