Search and Discovery


On July 9, 2003, a group of explorers achieved a goal sought for many years; discovery of the last resting place of the only German U-boat on the West Coast of the United States, the UB 88. The wreck was located after an exhaustive year-long search effort. A cursory assessment of the wreck was done using a tethered video camera and recording sonar. On August 27, 2003, scuba divers visited that resting place and brought back with them definitive photographic evidence of the identity of the submarine. This website is a historical and photographic record of the life, death and rediscovery of the UB 88.

UB 88 served ten months in the Imperial German Navy and sank 13 allied ships. After 20 months under special commission in the U. S. Navy, UB 88 dove for the last time on January 3, 1921 under the guns of the USS Wickes. For 80 years, UB 88 lay intact, upright and near her designed operating depth limit, undisturbed and undiscovered on the sandy bottom south of the Port of Long Beach, California. Despite knowledge of the UB 88’s existence from Navy action and press reports, the location of the UB 88 remained a topic of much debate within the small and furtive wreck diving community. Rumors surfaced periodically about the wreck having been found, or someone having coordinates for the sunken submarine. However, no proof of her discovery emerged until now.

In the U.S. Navy


UB 88 was one of six U-boats handed over to the United States by Great Britain after the surrender of the German High Seas Fleet. This small group of U-boats, dubbed “The Ex-German Submarine Expeditionary Force” had a dual mission: educate the U. S. Navy about technological innovations achieved by the Imperial Navy in submarine development and serve as a publicity vehicle for the U. S. Government’s efforts to fund its war deficit through the issuance of Victory Bonds. During the trip from Harwich, England, to her final arrival at the submarine base in San Pedro, California, she and her crew made calls to ports along the Atlantic coast, Gulf of Mexico, Mississippi River, coast of Panama and the West coast, “steaming” a total of 15,361 miles. Forty-five cities were visited, and over 400,000 visitors were shown through the boat. She was laid up for the next four months before being dismantled and decommissioned. Having concluded her mission, UB 88 was sunk by the U.S. Navy in a live fire exercise.
