UPDATE: USS John S. McCain arrives in Singapore after collision

Following a collision with merchant vessel Alnic MC east of the Straits of Malacca and Singapore on August 21, USS John S. McCain (DDG 56) pulled into Changi Naval Base, Singapore, under her own power, the US Navy’s 7th Fleet said.

The collision was reported at 6:24 a.m. Japan Standard Time.

The navy said significant damage to the hull resulted in flooding to nearby compartments, including crew berthing, machinery, and communications rooms. Damage control efforts by the crew halted further flooding.

None of the 10 sailors previously reported missing have been found and search efforts are still underway.

Four of five injured sailors were medically evacuated by a Singapore Armed Forces helicopter to a hospital in Singapore for non-life threatening injuries. The fifth does not require further medical attention.

Search and rescue efforts continue in coordination with local authorities. The Republic of Singapore Fearless-class patrol ships RSS Gallant (97), RSS Resilience (82), and Singaporean Police Coast Guard vessel Basking Shark (55) are in the area rendering assistance.

Additionally, MH-60S helicopters and MV-22 Ospreys from the amphibious assault ship USS America (LHA 6) are in the area providing search and rescue assistance.

Alnic MC is a Liberian-flagged 600-foot oil and chemical tanker with a gross tonnage of 30,000. According to the Maritime and Port Authority of Singapore (MPA), no crew member of the tanker was injured.

The navy said the incident will be investigated.
