The USS John S. McCain, an Arleigh Burke-class guided-missile destroyer collided with a Liberian merchant vessel August 21, 2017 near Singapore.
The Fitzgerald collided off the southern coast of Japan with a larger vessel on June 17, killing seven sailors, while the McCain struck another ship August 21 near Singapore, killing 10.
In the case of the USS Fitzgerald, the commander, two lieutenants and one lieutenant junior grade face possible charges of dereliction of duty, hazarding a vessel and negligent homicide.
The ship's arrival comes only days after the Navy announced Tuesday that it was seeking negligent homicide charges against four officers of the Fitzgerald at the time of the collision, including the then-commanding officer, Cmdr.
A pair of Navy commanders face negligent homicide charges over the collisions of two U.S. destroyers with merchant ships that left 17 sailors dead this summer, a new report found.
These courts-martial are the latest to develop from the investigations into the deadly collisions. The destroyer USS John S. McCain collided with an oil tanker in coastal waters off Singapore in August, killing 10 US sailors.
The Navy said it is continuing the investigation into the USS John S. McCain accident and could file charges against a senior enlisted sailor. A chief petty officer, whose name was not disclosed, faces a charge of dereliction of duty.
Cmdr. Garrett Miller, the Fitzgerald's commanding officer, says the crew will help oversee the work.
The Navy has already dismissed several senior officers, including the commander of the Seventh Fleet, as a result of the collisions.
In a statement, Hicks said the announcement of charges Tuesday is "not meant to and does not reflect a determination of guilt or innocence related to any offenses".
Hicks also included, "Additional administrative actions are being conducted for members of both crews including non-judicial punishment for four Fitzgerald and four John S. McCain crewmembers".
The Navy is filing negligent homicide charges against former high ranking officers who were deemed responsible for the attack.
