The U.S. aircraft carrier Gerald R. Ford, deployed in operations against Iran, is expected to temporarily pull into port after a fire on board, U.S. officials said on Tuesday, the 18th day ‌of the war with Tehran.

The carrier, America’s newest and the world’s largest, is currently located in the Red Sea. It is expected to temporarily go to Souda Bay on the Greek island of Crete, the two officials said.

The warship has been deployed for nine months, including taking part in operations against Venezuela in the Caribbean ⁠prior to arriving in the Middle East. The length of the deployment has raised questions about morale of the sailors on board and the readiness of the warship.
