151019-N-EW716-002 Norfolk, Va. (Oct. 19, 2015) The Military Sealift Command fleet ocean tug USNS Apache (T-ATF 172) is fueled before deploying. The ship departed Norfolk, Virginia, Oct. 19 to begin searching for wreckage from the missing U.S. flagged merchant vessel El Faro. Apache is equipped with several pieces of underwater search equipment, including a voyage data recorder locator, side-scan sonar and an underwater remote operated vehicle. The Navy's mission will be to first locate the ship and, if possible, to retrieve the voyage data recorder - commonly known as a black box. (U.S. Navy photo/Released)
