A U.S. Navy replenishment ship operating in the Middle East sustained damage in an incident which is under investigation, officials said Tuesday. The damage to the USNS Big Horn comes after the oiler has supplied the USS Abraham Lincoln aircraft carrier strike group and remains in the region amid heightened tensions over the Israel-Hamas war and Israel’s ongoing strikes targeting Hezbollah in Lebanon. Another U.S. official, who spoke on condition of anonymity for the same reason, said the vessel was being supported by private tugboats and an assessment was still ongoing for the vessel. A U.S. Navy official, speaking on condition of anonymity to discuss matters yet to be made public, said the damage happened in the Mideast, but declined to elaborate on its location. The official said the Big Horn’s crew was safe and there was no sign of an oil leak from the vessel. Rumors about the Big Horn’s condition began circulating early Tuesday after images posted to a website tracking shipping called gCaptain showed flooding purportedly on board the Henry J. Kaiser-class fleet replenishment oiler. The website described the Big Horn as having “ran aground … and partially flooded off the coast of Oman.” Though the Lincoln is powered by a nuclear reactor, its strike group has vessels powered by fossil fuel that need to be resupplied at sea. The aircraft aboard the Lincoln also need jet fuel. The Big Horn and other ships like it also provide other supplies.
