A fire broke out Wednesday onboard the U.S. Navy ship USS New Orleans off the coast of Japan’s Okinawa island, the Navy said in a statement.

Crews were responding to the fire in the early evening local time, a Navy spokesperson told Newsweek. The blaze was reported as contained and there were no injuries, although the extent of the damage was still unclear.

Why It Matters

Japan hosts the largest number of American service members anywhere in the world outside of U.S. territory. The U.S. military’s presence in Japan—part of a decades-long security treaty arrangement—at times has been a point of frustration for the local population, with accidents closely scrutinized.

Okinawa, a military hub and the largest of Japan’s southwestern islands, houses garrisons of every single U.S. armed forces branch, with the operations of the Okinawa naval base spanning over a dozen key sites. Around two-thirds of the 52,000 U.S. troops in Japan are stationed across the island.

What To Know

The Japan coast guard learned about the fire onboard the New Orleans just after 5 p.m. local time, when crews responding to the incident put in the first of two requests for firefighting assistance near the White Beach naval facility, according to Japanese broadcast NHK.

Black smoke was seen rising from the vessel, and footage aired by local news station RBC showed a tug boat spraying a column of water at the ship’s bow. An All-Nippon News Network TV crew showed firefighting efforts continuing into the night.

There were no requests to evacuate the ship’s crew, the report said, and the Japan coast guard observed no oil spills.

The New Orleans is a San Antonio-class amphibious transport dock that can carry up to 800 marines in addition to amphibious assault platforms like hovercraft and V-22 Osprey rotorcraft. The 24,400-ton warship measures 684 feet in length and 104 feet in width.

The White Beach naval base on the Katsuren peninsula is located within the Japanese city of Uruma.

The New Orleans, named for the Louisiana city where it was built, was commissioned by the Navy in 2007. In 2019, it was reassigned to its current home port of Sasebo in Kyushu, the southernmost of Japan’s main islands.

The Sasebo naval base is among the major facilities of the Japan-based U.S. Seventh Fleet, headquartered in Yokosuka, south of Tokyo at the mouth of Tokyo Bay. Yokosuka is also the home port of the Nimitz-class aircraft carrier USS George Washington, the Navy’s only permanently forward-deployed flattop.

What Happens Next

NHK said the New Orleans left Sasebo on August 14 and reached White Beach three days later. The cause of the fire remains unknown.
