As the commander of the U.S. Pacific Fleet, Swift oversees the 7th fleet.
The decision to dismiss Aucoin was made by Adm. Scott Swift, commander of the U.S. Pacific Fleet. "Rear Adm. Phil Sawyer. will assume command immediately".
The move to push Aucoin out comes days after the USS John S. McCain collided with an oil tanker near Singapore.
The guided-missile destroyer and the Alnic MC oil tanker collided about 4.5 nautical miles (8.3 kilometers) from Malaysia's coast at the start of a designated sea lane for ships sailing into the busy Singapore Strait.
"An expedited change in leadership was needed", a usa official told Reuters on Tuesday.
CNN reported that Vice Admiral Aucoin's role had come under scrutiny after incidents in which a US Navy vessel has been involved in a collision or grounding incident in the Pacific theatre of operations this year. The identities of the missing have not been disclosed but Partlow said her fiancee's parents were in touch with the Navy's family assistance center. The sea-based search east of Singapore is expanding to encompass a greater area as time goes on, it said. Five sailors were injured.
On Tuesday, it emerged that bodies had been found in the flooded compartments of the USS John S McCain. The Navy said the warship suffered "significant damage" to its hull, flooding crew berths, machinery and communications rooms.
The Navy's top officer on Monday ordered a pause in operations around the world.
Richardson said the review will examine the process of training and certifying forces, operational tempo, maintenance trends and other areas to determine the root cause of the incidents.
April Brandon in MI said the military informed her that her son Ken Smith is missing.
Megan Partlow of OH, who says her fiancee was on board the McCain, told The Associated Press in a Facebook message that they last communicated on Sunday and she was losing hope of seeing him again.

In January, the USS Antietam guided missile cruiser ran aground near Yokosuka base, the home port of the 7th Fleet, and in May another cruiser, the USS Lake Champlain from the Navys 3rd Fleet, had a minor collision with a South Korean fishing boat.
"The investigation is in its very earliest stages".
There were two lesser-known incidents in the first half of the year. "But I think the chief of naval operations was very clear that we are not taking any consideration off the table, and every scenario will be reviewed and investigated in detail".
