1954
First nuclear submarine launched
January 21, 1954
The USS Nautilus slid into the Thames River in Connecticut, the world's first nuclear-powered vessel. Her reactor meant she could stay submerged for months. Four years later she became the first ship to reach the North Pole, traveling under the polar ice cap. Naval warfare had acquired a new dimension and a new century of concealment.
