Haunting Deep-Sea Footage Reveals U.S. Submarine Lost During WWI
On December 17, 1917, the U.S. Navy submarine USS F-1, crashed off the coast of San Diego. Now, more than a century later, researchers at the Woods Hole Oceanographic Institute (WHOI) have collected the first high-definition visuals of the wreckage. During a series of seven dives conducted earlier this year, researchers employed the crewed underwater vehicle Alvin and autonomous underwater vehicle Sentry, both based on the WHOI research ship Atlantis, to snap close-ups of the sunken submarine. Since 1917, F-1 has been resting approximately 1,300 feet (400 meters) underwater. A Navy underwater vehicle located it by accident in the 1970s, but this expedition is the first to capture detailed images of the lost sub. The F-1 was built in 1901 and launched in 1911. The crash occurred during a training mission, during which the F-1 collided with another submarine, sinking in mere seconds. Nineteen crew members lost their lives, but five escaped and survived. By the time of the 1917 crash, the U.S. had been at war with the Central powers for seven months. '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 sub's senior pilot who helped lead the expedition, said in a statement. 'Once we identified the wreck and determined it was safe to dive, we were able to capture never-before-seen perspectives of the sub.' The team used multi-beam sonar systems on Atlantis and Sentry to produce maps of the F-1 and surrounding areas. Then, high-resolution cameras on Alvin picked up photos and videos of the wreck. The researchers stitched these images together to create detailed 3D photogrammetric models. The images showed that the F-1 is lying on the seafloor on its starboard (right) side, facing northwest, and is 'remarkably intact,' Strickrott told Live Science. The researchers left the war grave site untouched, however, 'to preserve its condition and be respectful of its legacy,' Bradley Krueger, an underwater archaeologist for the Naval History and Heritage Command who participated in some of the dives, told Live Science. During the series of dives, the researchers also surveyed a Navy torpedo bomber training aircraft that crashed nearby in 1950. The dives were part of a training and engineering mission to provide the Alvin pilots with experience controlling the submersible and employing deep-sea imaging technologies. The research was conducted as a collaboration between the U.S. National Science Foundation, University-National Oceanographic Laboratory System and the U.S. Navy's Office of Naval Research and Naval History and Heritage Command. After the dives, the researchers held a remembrance ceremony aboard the Atlantis, ringing a bell 19 times, once for each of the F-1's crew members who died in the crash. '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,' Strickrott said in a statement.

Never-before-seen photos reveal WWI-era submarine 1,300 feet before surface where 19 sailors perished in 1917
In Dec. 1917, 19 sailors serving on a World War I-era U.S. submarine made the ultimate sacrifice during a training mission. Perhaps fittingly, scientists have captured never-before-seen photos of its watery resting place off the California coast just ahead of Memorial Day. The U.S. Navy submarine, USS F-1, went down after a collision with its sister ship on Dec. 17, 1917, and now sits 1,300 feet below the surface on the ocean floor off San Diego. "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 in a statement. "All of us at the NHHC are grateful for this collaboration, which also enabled us to document and assess the condition of the crafts." The Naval History and Heritage Command's mission is to preserve and present an accurate history of the U.S. Navy. From Feb. 24 to March 4, researchers with the Woods Hole Oceanographic Institution (WHOI) used its human-occupied submersible Alvin, and an autonomous underwater vehicle known as Sentry belonging to the National Deep Submergence Facility, to capture close-up images of the wreck. "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 the submersible as it when it surveyed the submarine. "Lasting nearly eight hours, there was time to contemplate the risks that all mariners, past and present, face. sIt also reminded me of the importance of these training dives, which leverage the knowledge from past dives, lessons learned and sound engineering." While studying the submarine, the scientists also surveyed a Navy torpedo bomber training aircraft that went down in the same place in 1950. "Advanced ocean technology and simple teamwork played a big part in delivering these new images," said WHOI's Bruce Strickrott, manager of the Alvin Group and the sub's senior pilot who helped lead the expedition. "It was a profound honor to visit the wreck of the F-1." "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." Surveying the submarine involved seven dives that were part of a planned training and engineering mission to give submersible pilots-in-training practical experience. The team held a remembrance ceremony for the lost sailors, ringing a bell 19 times on the research vessel Atlantis directly above where the submarine lies. "History and archaeology are all about people and we felt it was important to read their names aloud," Krueger said. "The Navy has a solemn responsibility to ensure the legacies of its lost sailors are remembered." Advanced imaging technology helped the team document the wreck, including multibeam sonar systems on the Atlantis and Sentry that produced detailed, high-resolution maps of the submarine. That allowed the team to reconstruct the wreck using photogrammetry to make 3-D models. "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, NDSF chief scientist and co-lead of the expedition. "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."

Expedition captures the first ever images of the wreck of a World War I submarine
After more than 100 years, we have the first actual image of the wreck of a sunken U.S. Navy submarine from World War I. A recent expedition to survey it and other lost military hardware has captured video and photographs of the USS F-1. This week the Woods Hole Oceanographic Institution and Naval History and Heritage Command shared the results from a deep-sea dive conducted in February and March of this year. The ship the Atlantis carried a team of researchers, including trainees, to the waters off of San Diego, where they examined the wreck of the USS F-1 submarine and a Grumman TBM Avenger. Until this year there were only limited sonar readings showing the location of the lost submarine. The USS F-1 was originally discovered in 1975 while crews were searching for the wreck of an aircraft that crashed in the waters off of La Jolla. That discovery was conducted via sonar, with teams finding that the sub was 'completely intact' and it even spotted two periscopes. No plans were made to raise or salvage the submarine then. This expedition earlier this year was the first time archaeologists visited the wreck and the first time the USS F-1 was heavily photographed and filmed, giving the most detailed look at it yet. The team on the Atlantis conducted three dives, two at a sunken aircraft and one at the USS F-1. First they used an autonomous underwater vehicle to pinpoint the wrecks using multi-beam sonar, then a drone to examine it. Finally team members used a submersible to dive to the wreck where they took photos and video of the wreckage. The wreck is located roughly 400 meters below the surface. The USS F-1, originally laid down in 1909 as the USS Carp, entered service in 1912, and served as part of First Submarine Group, Pacific Torpedo Flotilla. The submarine had a mixed service; at one point it held the world record for the deepest dive at 86 meters, but it also ran aground shortly after it was commissioned. This was at a time where submarine warfare was becoming strategically important but submarines themselves were still dealing with several challenges. Many submarines could only dive for short periods of time and means of communication and sight were particularly hampered. The vessels themselves were much more cramped than submarines today — the F-1 was only 143-feet long. On Dec. 17, 1917, the USS F-1 was carrying out a maneuver exercise with other submarines near San Diego when it and another submarine, the USS F-3, collided. The F-3 suffered some damage, but the F-1's engine room and port side were breached, flooding the submarine. According to survivors, the submarine sank in seconds, taking on water quickly. 19 sailors of the USS F-1's 24-person crew died. 'Operating at sea has always been inherently dangerous, and even more so for early submarines. In this case, night, fog, speed, and radio miscommunications contributed to the loss of 19 men, who demonstrated great courage just by volunteering for submarine duty in those days,' Naval History and Heritage Command Director Sam J. Cox, U.S. Navy rear admiral (retired), said in a Navy release on the expedition's findings.

WWI sub captured in never-before-seen images off San Diego coast
On Dec. 17, 1917, the U.S. submarine USS F-1 was lost at sea during a training accident off the coast of California, killing 19 crew members on board. Now, just days before Memorial Day, scientists have announced they have captured unprecedented images of the final resting place of the World War I-era sub more than 1,300 feet below the ocean's surface The high-definition pictures of the USS F-1 were captured after a group of interagency teams used cutting-edge deep-sea imaging technology during an expedition earlier this year, according to news release from the Woods Hole Oceanographic Institution. USS F-1 collided with its sister ship, USS F-3, during exercises on the oean's surface off San Diego eight days before Christmas in 1917, according to the Submarine Force Library and Museum Association. USS F-1 sank in just 10 seconds, and only five of the sub's 24 crewmen were rescued. The sub was lost for nearly 60 years until it was located by a Navy deep submersible vehicle that was out looking for a jet fighter that crashed in 1972, the association said. "It looked like a big ax had hit her," said Lt. Dave Magyar, the pilot of the submersible that spotted the USS F-1, according to a newspaper story from 1976. But a close-up survey was not possible given the depth of the submarine. Until now. With assistance from the Office of Naval Research (ONR), the Naval History and Heritage Command (NHHC) and the National Science Foundation, the Woods Hole Oceanographic Institution team dispatched a human-occupied vehicle named Alvin as well as a remote underwater vehicle named Sentry to capture the close-up images. Using sonar systems on Sentry and the research vessel Atlantis, the team was able to successfully conduct meticulous surveys of the submarine. "Once we identified the wreck and determined it was safe to dive, we were able to capture never-before-seen perspectives of the sub," said WHOI's Bruce Strickrott, the senior pilot who helped lead the expedition. "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." During the expedition, the team also captured images of a U.S. Navy Avenger torpedo bomber training aircraft that crashed near the same area in 1950. Scientists released video and images of the aircraft, showing a severely damaged tail and a bent front propeller. The team conducted seven dives of the F-1 wreck site and the advanced sonar systems were able to produce detailed maps of the submarine and surrounding seafloor. Scientists also used high-resolution cameras to capture close-up video of the wreck. Specialists then used all the data to stitch together "photogrammetric models capable of providing precise measurements of the sub and the animals that have colonized its wreckage over the years." That allowed experts to reconstruct the F-1 submarine and produce stunning 3-D models of the wreck. After the dives, the team held a remembrance ceremony on board Atlantis, ringing a bell 19 times—one for each crew member lost at sea. "History and archaeology are all about people and we felt it was important to read their names aloud," said underwater archaeologist Brad Krueger, who participated in the dives.
