Atlantis Submarines International, Inc. is responsible for taking more than 11 million passengers on undersea adventures aboard its 48 and 64-passenger submarines. A fleet larger than that of many national navies, Atlantis subs are now found in Grand Cayman, Barbados, St. Thomas, Aruba, Guam, Cozumel, and on the Hawaii Islands of Hawaii, Maui and Oahu.

Last year the organization employed approximately 450 people, operating 11 tourist submarines and several other tours at 11 locations around the world, and carried almost 1 million passengers. Among Atlantis' passengers are over 40,000 local school children, whose classes participated in the company's "Living Classroom" program. If it's not an Atlantis Adventures it's not a real adventure.
