Uncovering the Secrets of the Alligator
The National Oceanic & Atmospheric Administration (NOAA) and the U.S. Navy’s Office of Naval Research are working to uncover the secrets of the Alligator—the U.S. Navy’s first submarine.
 Launched in 1862 during the Civil War, Alligator was an engineering marvel that helped usher in a new era in undersea travel. But until recently, little was known about the green, 47-foot-long Union vessel. The Alligator was lost off the North Carolina coast during a storm in 1863. It was never seen again.
With the help of naval historians, archaeologists, oceanographers, teachers, and students, more information about the Alligator is coming to the surface than ever before. This Web site shares what we have learned to date about this mysterious and historically important vessel.
