10 sailors on USS John S. McCain
At 5:24 a.m. on 21 August 2017, USS John S. McCain, a United States Navy warship, was involved in a collision with the Liberian-flagged tanker Alnic MC off the coast of Singapore and Malaysia, east of the Strait of Malacca.[1][2][3] According to a U.S. Navy press release, the breach "resulted in flooding to nearby compartments, including crew berthing, machinery, and communications rooms."[4] Ten US Navy sailors died as a result of the crash, which prompted the Maritime and Port Authority (MPA) of Singapore to start a multi-agency search-and-rescue (SAR) effort as the agency responsible for coordinating SAR operations within Singapore's Maritime Search and Rescue Region (MSRR).[5][6][3][7][8] The Singapore Transport Safety Investigation Bureau (TSIB) also launched a marine safety investigation following the collision in accordance with the International Maritime Organisation's Casualty Investigation Code in Singapore's capacity as a coastal state, and published its final report on 8 March 2018.[9] The U.S. Navy announced on 24 August 2017 that it had suspended search-and-rescue efforts for survivors in the open sea to focus on the recovery of the remains of the missing sailors still inside the flooded compartments of the ship.[10] By 27 August, U.S. Navy and United States Marine Corps divers had recovered the remains of all ten sailors.[11] On 12 September 2017, the United States' chargé d'affaires Stephanie Syptak-Ramnath expressed thanks for Singapore's support during the SAR operations.[12] The McCain returned to service in June 2020.[13]
