(CNN) The commanding officer, executive officer and senior non-commissioned officer of the USS Fitzgerald have been removed from their duties for cause amid the fallout surrounding the deadly collision between the USS Fitzgerald and a cargo ship off the coast of Japan on June 17.

"We've lost trust and confidence in their ability to lead in those positions and they will not return to the ship," Vice Chief of Naval Operations Adm. William Moran told reporters at the Pentagon late Thursday. The 7th Fleet also said several junior officers were relieved of duty.

While the final investigation into the collision is ongoing, Moran said: "We do not have to have the investigation complete to start the process."

The Fitzgerald's commanding officer, Cdr. Bryce Benson, and the executive officer, Cdr. Sean Babbiit, were both sleeping, and the master chief petty officer, Brice Baldwin, were not on the bridge at the time of the collision, according to the Navy.

The bow of the cargo ship directly struck the commander's cabin, according to the Navy's report detailing the immediate aftermath of the collision.
