Video: World War I submarine found off San Diego coast
The USS F-1, a World War I-era U.S. Navy submarine, was recently discovered by researchers off the cost of San Diego, California. The discovery comes 108 years after the submarine was 'lost at sea' in a training accident in December of 1917. In a recent press release, Woods Hole Oceanographic Institution (WHOI) announced, 'A deep-sea training and engineering dive off the coast of San Diego provided an opportunity for never-before-seen imagery of the U.S. Navy submarine USS F-1, lost at sea in an accident on December 17, 1917, that resulted in the death of 19 crew members.' According to the press release, WHOI researchers captured images of the World War I-era Navy submarine by using 'Sentry,' an autonomous underwater vehicle, and 'Alvin,' a human-occupied vehicle, to access the remains of the submarine located under more than 1,300 feet of water. 'Advanced ocean technology and simple teamwork played a big part in delivering these new images,' Bruce Strickrott, manager of the Alvin Group at WHOI and the senior pilot who helped lead the recent expedition, said. 'Once we identified the wreck and determined it was safe to dive, we were able to capture never-before-seen perspectives of the sub. As a U.S. Navy veteran, it was a profound honor to visit the wreck of the F-1 with our ONR and NHHC colleagues aboard Alvin.'

'It was an incredibly exciting and humbling experience to visit these historically significant wrecks and to honor the sacrifice of these brave American Sailors,' Naval History and Heritage Command (NHHC) Underwater Archaeologist Brad Krueger said. 'All of us at the NHHC are grateful for this collaboration, which also enabled us to document and assess the condition of the crafts.' According to the press release, the crew on the Atlantis, which was stationed above the location of the remains of the USS F-1, held a remembrance ceremony in honor of the 19 Navy members who were killed in the training incident in 1917. 'History and archaeology are all about people and we felt it was important to read their names aloud,' Krueger stated. 'The Navy has a solemn responsibility to ensure the legacies of its lost Sailors are remembered.' A video shared on X, formerly Twitter, by WHOI shows the new footage of the USS F-1 submarine as well as part of the ceremony held in honor of the 19 Navy members.

108-year-old submarine wreck seen in stunning detail in new footage
In 1917, two US submarines collided off the coast of San Diego and submarine USS F-1 sank to the bottom of the Pacific Ocean, along with 19 crew members aboard. The horrible accident, whose wreckage was discovered in 1975, represents the US Naval Submarine Force's first wartime submarine loss. Now, researchers from Woods Hole Oceanographic Institution have captured new footage of the 1,300 feet-deep underwater archaeological site. 'They were technical dives requiring specialized expertise and equipment,' Anna Michel, a co-lead of the expedition and chief scientist at the National Deep Submergence Facility, said in a statement. 'We were careful and methodical in surveying these historical sites so that we could share these stunning images, while also maintaining the reverence these sites deserve.' The high-definition imagining and mapping of the USS F-1 took place during a deep-sea training and engineering mission in February and March. The missions aimed to train future submersible pilots and test the human-occupied vehicle Alvin and autonomous underwater vehicle Sentry. The team captured never-seen-before images and videos and conducted a sonar survey, which essentially consists of mapping a region by shooting sound waves at it and registering the echo. Imaging specialists combined the 2D images into a 3D model of the wreck—a technique called photogrammetry. Using photogrammetry reveals measurements not just of the submarine but of the marine life that over the past century has claimed the vessel as its own. 'As a Navy veteran, making this dive—together with another Navy veteran and a Navy historian—was a solemn privilege,' said Office of Naval Research Program Officer Rob Sparrock, who was in Alvin when it went down to the wreck. 'There was time to contemplate the risks that all mariners, past and present, face. It also reminded me of the importance of these training dives, which leverage the knowledge from past dives, lessons learned and sound engineering.'

After the dives, they held a remembrance ceremony aboard the research vessel Atlantis during which a bell rang once for each of the crew members lost in 1917. 'History and archaeology are all about people and we felt it was important to read their names aloud,' said Naval History and Heritage Command Underwater Archaeologist Brad Krueger, who also dove in Alvin. 'The Navy has a solemn responsibility to ensure the legacies of its lost Sailors are remembered.'

Deep-sea technology captures images of WWI submarine, 100 years after it sank near San Diego
SAN DIEGO (FOX 5/KUSI) — A team of researchers captured high-definition pictures of a sunken World War I-era U.S. Navy submarine off the coast of San Diego, over a century after it was lost at sea. The USS F-1 was involved in a training accident eight days before Christmas Day in 1917, which killed all 19 crew members on board. Three La Jolla homes designated 'historic' by San Diego board With the help of advanced deep-sea imaging technology, researchers were able to capture high-quality images of the submarine's wreckage, discovered more than 1,300 feet under the ocean's surface just west of San Diego. Researchers from the Woods Hole Oceanographic Institution (WHOI) dispatched a human-operated submersible called Alvin and another underwater vehicle called Sentry, both belonging to the National Deep Submergence Facility (NDSF), to capture the images. (See images below) 'While these depths were well within the dive capability for Alvin and Sentry, they were technical dives requiring specialized expertise and equipment,' said Anna Michel, co-lead of the expedition and NDSF chief scientist. The team conducted surveys of the submarine using sonar systems on Sentry and a research vessel, Atlantis. They also surveyed the wreckage of a Navy Avenger torpedo bomber that crashed near the area where the USS F-1 sank. 'We were careful and methodical in surveying these historical sites so that we could share these stunning images, while also maintaining the reverence these sites deserve,' Michel stated. A remembrance ceremony later took place onboard Atlantis to commemorate the lives lost during the submersible's training accident 100 years ago. A bell was rung 19 times in honor of each crew member lost at sea, according to a news release by the institution. 'As a Navy veteran, making this dive—together with another Navy veteran and a Navy historian—was a solemn privilege,' said ONR Program Officer Rob Sparrock, who was among those on board the Alvin. 'Lasting nearly eight hours, there was time to contemplate the risks that all mariners, past and present, face.' The surveys and high-definition images of the USS F-1 were gathered with the assistance of the Office of Naval Research, the University-National Oceanographic Laboratory System, Naval History and Heritage Command and WHOI.

Lost for over 100 years, World War 1 era US submarine found along with bomber that sank in same area in 1950
Live Events USS F-1 Tragedy (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel In a historic deep-sea expedition off the coast of San Diego, researchers have captured stunning, never-before-seen imagery of the U.S. Navy submarine USS F-1 , which sank on December 17, 1917, following a fatal collision during a training exercise. The accident claimed the lives of 19 crew members, whose final resting place has now been thoroughly surveyed and documented using state-of-the-art underwater high-resolution images of the World War I-era submarine were taken during a joint research expedition conducted from February 24 to March 4, 2025, by the Woods Hole Oceanographic Institution (WHOI) and several interagency partners, including the U.S. Navy, the National Science Foundation (NSF), and the Naval History and Heritage Command (NHHC).Using advanced deep-sea imaging tools such as the human-occupied vehicle (HOV) Alvin and the autonomous underwater vehicle (AUV) Sentry, researchers successfully located the submarine more than 1,300 feet (400 meters) below the mission also captured detailed imagery of a U.S. Navy Grumman TBF Avenger torpedo bomber that crashed nearby during a training flight in 1950.'Advanced ocean technology and simple teamwork played a big part in delivering these new images,' said Bruce Strickrott, senior pilot of Alvin and manager of WHOI's Alvin Group. 'As a U.S. Navy veteran, it was a profound honor to visit the wreck of the F-1 with our ONR and NHHC colleagues aboard Alvin.'The discoveries were made during a scheduled training and engineering dive intended to test equipment and develop new deep-sea research techniques. Alongside the technology trials, the expedition served as a somber reminder of the risks faced by sailors past and present.'It was an incredibly exciting and humbling experience to visit these historically significant wrecks and to honor the sacrifice of these brave American Sailors,' said Brad Krueger, underwater archaeologist for the NHHC, who completed his first dive aboard Alvin to visit the F-1 USS F-1, originally conducting a 48-hour performance test, was lost when it collided with the USS F-3 in dense fog. Only three crew members survived. More than a century later, the wreck has been found lying intact on its starboard side, remarkably preserved by the deep-sea honor the fallen, a remembrance ceremony was held aboard the research vessel Atlantis, where the names of the 19 lost sailors were read aloud, and a bell rang 19 times—once for each life lost.'The Navy has a solemn responsibility to ensure the legacies of its lost Sailors are remembered,' said Krueger. 'History and archaeology are all about people, and we felt it was important to read their names aloud.'Advanced imaging tools, including multi-beam sonar and high-resolution cameras, enabled the creation of 3D photogrammetric models of the submarine and bomber wrecks. These reconstructions provide not only educational and historical value but also serve as crucial training assets for future oceanographic missions.'We were careful and methodical in surveying these historical sites so that we could share these stunning images, while also maintaining the reverence these sites deserve,' said Anna Michel, NDSF chief scientist and co-lead of the expedition.
