The Naval History and Heritage Command’s Underwater Archaeology Branch is responsible for the management, preservation, research, and interpretation of the U.S. Navy’s sunken military craft. The Navy oversees one of the largest collections of submerged cultural resources, which includes over 2,500 shipwrecks and more than 14,000 aircraft wrecks dispersed globally.
Depicted below and arranged according to cause of loss are the primary casualties suffered by the U.S. Navy following the nation's entrance into World War I and up until the signing of the Treaty of Versailles on June 28, 1919. Each casualty is linked to its respective Dictionary of American Naval Fighting Ships (DANFS) entry, along with an image, where available, housed in the Photographic Archives of the Naval History and Heritage Command.
The locations of losses are purposefully approximated and icons will eventually vanish as the map scale diminishes. Sunken military craft under the jurisdiction of the Department of the Navy remain government property regardless of their location or the passage of time and are afforded protection from unauthorized disturbance under the Sunken Military Craft Act.
