Three other officers aboard the Fitzgerald also will face charges, said Navy Capt. Gregory Hicks, a service spokesman. The service did not identify them by name Thursday, but they include two lieutenants and one lieutenant junior grade. They and Benson also face charges of dereliction of duty and hazarding a vessel.
Sanchez faces the same three charges in connection with the McCain accident, Hicks said in a statement. In addition, the Navy is examining one charge of dereliction of duty against a chief petty officer, a senior enlisted leader on the ship.
Separately, the service also is moving forward with administrative discipline for four other members of both the Fitzgerald and McCain, Hicks said.
The potential courts-martial are the latest fallout to the collisions, which shocked the Navy, prompted congressional hearings and has left the service short two $1.8 billion destroyers. Navy Adm. John M. Richardson, the chief of naval operations, has promised that the service will get back to basics and emphasize the fundamentals of good seamanship.
The service announced in November that it had found through internal investigations that both catastrophes were preventable and occurred due to multiple failures by service members who were standing watch the nights of the accidents.
Richardson disclosed at a Pentagon news conference Nov. 2 that he had assigned Adm. James “Frank” Caldwell Jr. to serve as a consolidated disposition authority for legal cases related to the collisions. The term defines a senior officer who oversees cases that can be both criminal and administrative in nature.
The service already had removed numerous people from their jobs as a result of the collisions, including Sanchez and his second-in-command on the McCain, Cmdr. Jessie L. Sanchez. On the Fitzgerald, the Navy removed Benson, Cmdr. Sean Babbitt, the ship’s No. 2 officer, and Command Master Chief Brice A. Baldwin, its senior enlisted sailor.
In August, the Navy removed Vice Adm. Joseph Aucoin, who oversaw its 7th Fleet. Aucoin’s replacement, Vice Adm. Phil Sawyer, then removed Rear Adm. Charles Williams and Capt. Jeffrey Bennett, who oversaw aspects of the ships’ deployments.
In September, Richardson notified Adm. Scott Swift, the commander of U.S. Pacific Fleet, that he will not be nominated to lead U.S. Pacific Command, effectively pushing him into retirement.
The Navy’s senior officer overseeing surface warfare, Vice Adm. Thomas Rowden, also is expected to step down this week ahead of a recommendation that he be removed, Defense News reported Tuesday.
An earlier version of this story mischaracterized Richardson’s decision about Adm. Scott Swift. The story has been corrected.
