Savannah

Savannah, name of 2 historic U.S. steamships. The first Savannah was the first steamship to cross the Atlantic (1819), sailing from Savannah, Ga. to Liverpool, England in 24 days, powered by sails as well as steam. The second, built by the U.S. government and launched in 1959, was the first nuclear-powered cargo ship. This 595.5-ft (195-m)-long ship, which can carry 60 passengers and 9,400 tons of cargo, proved commercially impractical.
