The USS Nautilus joined the Fleet. She was commissioned on September 30th, 1954.
Nautilus was an experiment from start to finish. As an operational boat, about all that she could do was stay submerged for long periods of time. She was noisy and her passive sonar was noise-limited to speeds that could be easily surpassed by submerged diesel boats. But she was a success at her main task: Giving the Navy experience in operating nuclear power plats at sea.
After Nautilus, the Navy kept tweaking sub design with class sizes of between one and six boats until the construction of the Thresher/Permit class, which was the first SSN class of more than ten boats.
