The Navy’s big green monster!

The National Oceanographic and Atmospheric Administration, with support from the Office of Naval Research, returned to the "Graveyard of the Atlantic" to continue the search for the Alligator, the U.S. Navy's first submarine. The joint expedition took place off Cape Hatteras, where the Civil War vessel was lost during a fierce storm in 1863. Based in Ocracoke, N.C., the 2005 survey was part of an ongoing effort to solve the mystery of the Alligator's demise while promoting scientific and historical research, education and ocean literacy.

In 1869, Jules Verne wrote Twenty Thousand Leagues Under the Sea, a novel about circumnavigating the globe underwater, in which he introduced readers to Captain Nemo’s submarine, Nautilus.
Lauded ever since for predicting the advent of maritime travel under the waves, Verne was actually expanding upon the recent inventions of various men who applied the use of “sub-marines†to both commerce and warfare.
The brainchild of one such man — Brutus de Villeroi — became the first submarine adopted for use by the U.S. Navy.
