Vice Admiral Aucoin relieved of command; Pacific Fleet commander cites "loss of confidence."
The U.S. Navy on Wednesday said it had removed Seventh Fleet Commander Vice Admiral Joseph Aucoin after a series of collisions involving its warships in Asia as the search goes on for 10 sailors missing since the latest mishap.
Aucoin's removal comes after a pre-dawn collision between a guided-missile destroyer and a merchant vessel east of Singapore and Malaysia on Monday, the fourth major incident in the U.S. Pacific Fleet this
"Admiral Scott Swift, commander of U.S. Pacific Fleet, today relieved the commander of Seventh Fleet, Vice Admiral Joseph Aucoin, due to a loss of confidence in his ability to command," the U.S. Navy said in a press release.
Swift, who traveled to Japan to relieve Aucoin, ordered his deputy Pacific Fleet commander, Rear Admiral Phil Sawyer, to immediately take command of the powerful U.S. force.
Aucoin was due to step down next month, with Sawyer, a submariner by trade, already slated to succeed him. Aucoin came up through the Navy's air wing as an F-14 navigator.
"I support Admiral Swift's decision to bring in new leadership. The new Seventh Fleet Commander must help move his team forward, focusing efforts on safe and effective operations," U.S. Navy Chief of Naval Operations Admiral John Richardson said in a statement.
The Seventh Fleet, headquartered in Japan, operates as many as 70 ships, including the U.S. Navy's only forward-deployed aircraft carrier, and has around 140 aircraft and 20,000 sailors.
It operates over an area of 124 million square km (48 million square miles) from bases in Japan, South Korea and Singapore.
The accident involving the USS John S. McCain and the tanker Alnic MC in the Singapore Strait came at a tense time for the U.S. Navy in Asia.
This month, the John S. McCain sailed within 12 nautical miles of an artificial island built by China in the disputed South China Sea, the latest "freedom of navigation" operation to counter what the United States sees
as China's efforts to control the contested waters.
An official Chinese newspaper said on Tuesday the U.S. navy's latest collision shows it is becoming an increasing risk to shipping in Asia despite its claims of helping to protect freedom of navigation.
Also this month, North Korea threatened to fire ballistic missiles towards the U.S. Pacific territory of Guam in a standoff over its nuclear and missile programmes.
"Losing another ship now is bad timing. It may raise concern over America's defensive capabilities and it could send the wrong signal to North Korea and China," a senior Japanese Maritime Self Defence Force officer said, asking not to be identified because he is not authorized to talk to the media.
An international search-and-rescue operation involving aircraft, divers and vessels from the United States, Singapore, Malaysia, Indonesia, and Australia is looking for the 10 U.S. sailors missing since Monday's collision.
On Tuesday, U.S. Navy and Marine Divers found human remains inside sealed sections of the damaged hull of the USS John S McCain, which is moored at Singapore's Changi Naval Base. The Navy has not yet announced the identities of the bodies discovered.
The U.S. Navy is also working to identify a body found by the Malaysian navy about eight nautical miles northwest of the collision site. Photos posted on the Twitter account of a Malaysian navy frigate on Wednesday showed crew carrying what appeared to be a body to a U.S. Navy helicopter.
The latest collision has already prompted a fleet-wide investigation and plans for temporary halts in U.S. Navy operations.
The John S. McCain's sister ship, the USS Fitzgerald, almost sank off the coast of Japan after colliding with a Philippine container ship on June 17. The bodies of seven U.S. sailors were found in a flooded berthing area after that collision.
