The Navy fired the top two officers assigned to the destroyer USS John S. McCain after the deadly collision two months ago, the U.S. Pacific Fleet announced late Tuesday.

Commanding officer Cmdr. Alfredo Sanchez and executive officer Cmdr. Jessie Sanchez were relieved due to a loss of confidence by Vice Adm. Phil Sawyer. The destroyer collided with the merchant vessel Alnic MC on Aug. 21, killing 10 sailors.

"While the investigation is ongoing, it is evident the collision was preventable, the commanding officer exercised poor judgement, and the executive officer exercised poor leadership of the ship's training program," Pacific Fleet said in a statement.

Cmdr. Ed Angelinas, previously the commanding officer of USS McCampbell, has been named acting commanding officer, and Lt. Cmdr. Ray Ball, chief engineer of the cruiser USS Antietam, has been named acting executive officer.

Sanchez has been assigned to Naval Forces Japan and will serve at Ship Repair Facility Yokosuka.

The McCain collision, combined with an earlier collision involving the USS Fitzgerald, which claimed the lives of seven sailors, has prompted two fleetwide investigations and has ended the careers of several high-ranking officials, including the three-star commander of the 7th Fleet, the head of Combined Task Force 70, the commodore of Destroyer Squadron 15, and the top three official assigned to the Fitzgerald.
