Discovery of USCGC Tampa Wreckage
On 30 April 2026 the U.S. Coast Guard announced that the wreck of USCGC Tampa, lost in 1918, had been located about 50 mi (80 km) off Newquay, Cornwall, at a depth of more than 300 ft (90 m). British technical-diving team Gasperados confirmed the find after ten exploratory dives. The announcement noted that the find concluded a three-year research effort.
Historical Context
Tampa was torpedoed by a German submarine in the Bristol Channel during World I, sinking in under three minutes and killing all 131 aboard. The incident remains the deadliest single American naval combat loss of the war.
Search Timeline and Participants
The search began in 2023 when Gasperados contacted the Coast Guard’s Atlantic Area Historian’s Office, led by William Thiesen, for archival images and technical data. Over 2023-2025 the team conducted ten dives at likely sites. Admiral Kevin Lunday, commandant of the Coast Guard, oversaw the effort, while Steve Mortimer led the British dive team.
Wreckage Details
The wreck lies 50 mi off Newquay at >300 ft depth. All 131 crew and passengers are presumed lost. The vessel’s structural features matched historic photographs, confirming its identity as USCGC Tampa.
Significance
Locating the wreck provides a definitive resting place for those lost, closing a century-old historical gap. The site offers opportunities for maritime archaeology and for studying early 20th-century naval construction. The Coast Guard plans further underwater research and preservation.
Official Responses
Admiral Lunday highlighted the enduring relevance of the crew’s sacrifice and the connection forged by the discovery. Historian Thiesen noted the use of deck-fitting, wheel, bell, and weaponry images to verify the wreck. Mortimer described the operation as a multi-year research project that resolves a long-standing question for families.
