Military Sealift Command hospital ship USNS Mercy (T-AH 19) departed Naval Station San Diego May 3, beginning its part in Pacific Partnership 2012, a four-and-a-half month humanitarian and civic assistance mission to Indonesia, the Philippines, Vietnam and Cambodia. Mercy is crewed by 70 civil service mariners working for MSC who operate and navigate the ship while Navy planners and medical personnel plan and execute the mission. Mercy was scheduled to depart May 1, but a mechanical problem delayed the ship’s departure for two days.
