The Navy declared a fire aboard the amphibious transport dock USS New Orleans extinguished following a 12-hour battle Wednesday night off the coast of Okinawa, Japan.
U.S. 7th Fleet officials said the fire began at 4 p.m. Wednesday afternoon while the ship was anchored off the White Beach Naval Facility.
The crew quickly responded, assisted by sailors from another San Antonio-class amphibious transport dock, the USS San Diego, which was moored at the naval facility. Service officials said an investigation is underway as to the cause of the fire.

The crew was able to remain on the ship following the fire, although Navy officials said services and berthing were available on the San Diego, as well as Fleet Activities Okinawa.
Two sailors were taken to the vessel's medical clinic for treatment of minor injuries, according to the Navy.
The New Orleans was commissioned in 2007 in its namesake city and originally was homeported in San Diego, deploying extensively around the globe. In 2009, the ship suffered minor damage when it was struck by the attack submarine USS Hartford in the Strait of Hormuz.
In 2015, its crew played a pivotal role in safely evacuating the aircrew and Marine passengers of an MV-22 Osprey that crashed on its deck during pre-deployment training exercises.
The last major fire aboard a U.S. Navy vessel occurred in 2020 on the Wasp-class amphibious assault ship USS Bonhomme Richard while it was in maintenance in San Diego. That fire burned for four days and destroyed the ship.
The cause of that fire was thought to be arson, although the sailor who was charged was acquitted at trial. An investigation also determined that the Navy's fire protocols were not followed and that the vessel had missing fire hoses and a broken sprinkler system.
In that fire, 63 people, including 40 sailors and 23 civilians, were treated for minor injuries such as heat exhaustion and smoke inhalation.
Meanwhile, the Defense Department and military services have started replacing the fire retardant used on military installations with foam that is less hazardous to the environment. Aqueous film forming foam, or AFFF, is highly effective but contains per- and polyfluorinated chemicals, or PFAS, that do not break down naturally and have been linked to several types of cancer and developmental delays in children.
The U.S. Navy continues to use AFFF on ships, where fires can be particularly dangerous or lethal. In a 2023 report to Congress, the Defense Department said new Navy ships are being designed with alternative fire suppression systems, but "limited use of [PFAS-containing systems] remains for those spaces where the alternatives are not appropriate," such as existing ships.
According to the report, "the safety and survivability of naval ships and crew from fires on ships depends on current PFAS-based firefighting foams and their use will continue until a capable alternative is found," officials wrote.
According to 7th Fleet officials, the Japan Maritime Self-Defense Force and Japan Coast Guard assisted in the response to the USS New Orleans fire. Local media reports showed a Japanese firefighting vessel dowsing the New Orleans' deck with water.
As of Thursday, the New Orleans remained at anchor with the Japanese tug Reiwa standing by, according to the app Marine Traffic.
