In 1961, NNS built its first nuclear aircraft carrier. What was it called?

The first nuclear aircraft carrier built by Newport News Shipbuilding (NNS) in 1961 was the USS Enterprise, designated as CVAN-65. This vessel was significant for its time, introducing nuclear propulsion to the aircraft carrier fleet, which allowed for longer deployments without the need for refueling. The USS Enterprise was a pioneering ship, known for its innovative design and technological advancements, marking a pivotal moment in naval engineering and military capability.

The other options listed do not correspond to the first nuclear aircraft carrier. The USS Ranger and USS Robert E. Lee are notable ships but were not the first of their class. The Tugboat Dorothy does not relate to aircraft carriers at all, emphasizing the unique status of the USS Enterprise in naval history as a trailblazer for future nuclear vessels.
