July 1959: Savannah Afloat!
The last half of the 1950s was a time of great promise for the concept of atomic-powered commercial ships. The idea was given real political momentum (which it very much needed) in 1955 when President Eisenhower formally proposed construction of such a ship by the United States. In July 1956, Congress passed Public Law 848, authorizing the actual engineering and construction of the ship.
