The USS Benfold, an Arleigh Burke-class guided-missile destroyer, suffered the outage on July 24 while sailing with the George Washington Carrier Strike Group, according to Cmdr. Matthew Comer, a spokesperson for the US 7th Fleet.
The power failure left the crew without potable water, hot meals, working toilets and air conditioning for four days.
Comer said the incident was caused by a problem with the ship's generators. No crew members were injured, and he praised the sailors for their resilience and professionalism during the outage.
The Benfold, which is around 30 years old, was subsequently towed by contracted tugboats to Subic Bay in the Philippines. The destroyer arrived on July 28, where Navy maintenance specialists began repairs.
Starting the following day, sailors were provided with food and moved to contracted accommodation ashore, Comer said.
Power was restored on July 30, while repairs to the ship were completed on August 7. The Benfold departed Subic Bay on August 8.
The Navy has not publicly explained why the incident was not disclosed when it occurred. ABC News reported that it had contacted the Navy for additional information about the circumstances surrounding the failure.
The incident comes as the US Navy faces pressure from multiple global commitments, including operations linked to the Iran war. The George Washington Carrier Strike Group is expected to relieve the USS Abraham Lincoln in the Middle East, where the Lincoln and its crew have been involved in an extended deployment.
It remains unclear whether the Benfold returned to its home port in Japan after leaving the Philippines or continued operating with the George Washington Carrier Strike Group.
