The carrier "remains poised for full mission tasking in support of national objectives in any area of operation," according to the Navy, which said the ship "completed scheduled repairs and received supplies to sustain operations."

The carrier played a major role in the US-Israeli air campaign against Iran but sailed to Crete and then Croatia after a laundry fire broke out on March 12.

The blaze injured two sailors and caused major damage to some 100 beds, according to the US military. The Navy said Thursday that the "routine investigation into the ship's laundry and berthing fire is ongoing."

The Ford's exit from Iran operations left a gap in US forces in the region, taking the number of carriers deployed there from two to one.

But the USS George H.W. Bush aircraft carrier and its accompanying warships left port for what the military described as a "regularly scheduled deployment" on Tuesday, and it is reportedly bound for the Middle East.

The Ford has been at sea for more than nine months -- a deployment that has already seen it take part in US operations in the Caribbean, where Washington's forces have carried out strikes on alleged drug-smuggling boats, interdicted sanctioned tankers and seized Venezuelan leader Nicolas Maduro.
