An Australian warship carrying a unmanned underwater drone, a U.S. black box detector and acoustic detection equipment was readying to set sail as part of the search for missing Flight MH370 on Sunday, NBC News reported. Scheduled to depart on Monday, the Ocean Shield would take about four days to reach the search area off of Australia's western coast. The black box detector, known as a ping locator, has been provided by American officials and will be deployed once the vast area has been narrowed after finding wreckage. "(Black box pingers) are rated to last 30 days, but that is a minimum. In my experience they do last a little bit longer than that," said the U.S. Navy supervisor of salvage and diving, Capt. Mark Matthews, according to local newspaper Perth Now. "I would say 45 days is the realistic limited expectation."
