On Jan. 10, 2007, the nuclear submarine USS Newport News, traveling submerged, struck M/V Mogamigawa, a 300,000-ton Japanese-flagged very large crude tanker, south of the strait. Similarly, on March 20, 2009, United States Navy Los Angeles-class submarine USS Hartford (SSN-768) collided with the San Antonio-class amphibious transport dock USS New Orleans (LPD-18) in the strait. The collision, which slightly injured 15 sailors aboard the Hartford, ruptured a fuel tank aboard the New Orleans, spilling 25,000 gallons of marine diesel fuel. __
