January 21, 1954: The USS Nautilus, the world's first nuclear-powered submarine, is christened by first lady Mamie Eisenhower. It is the sixth U.S. warship to carry that name.
Nautilus' christening took place less than three years after Congress first authorized construction of a nuclear-powered submarine for the U.S. Navy. It was commissioned in September 1954 and entered active service Jan. 17, 1955.
