On Dec. 17, 1917, the U.S. submarine USS F-1 was misplaced at sea throughout a coaching accident off the coast of California, killing 19 crew members on board. Now, simply days earlier than Memorial Day, scientists have introduced they’ve captured unprecedented pictures of the ultimate resting place of the World Warfare I-era sub greater than 1,300 ft beneath the ocean’s floor
USS F-1 collided with its sister ship, USS F-3, throughout workouts on the oean’s floor off San Diego eight days earlier than Christmas in 1917, in accordance with the Submarine Power Library and Museum Affiliation. USS F-1 sank in simply 10 seconds, and solely 5 of the sub’s 24 crewmen had been rescued. The sub was misplaced for almost 60 years till it was situated by a Navy deep submersible automobile that was out in search of a jet fighter that crashed in 1972, the affiliation stated.
Till now.

With help from the Workplace of Naval Analysis (ONR), the Naval Historical past and Heritage Command (NHHC) and the Nationwide Science Basis, the Woods Gap Oceanographic Establishment group dispatched a human-occupied automobile named Alvin in addition to a distant underwater automobile named Sentry to seize the close-up pictures.
Utilizing sonar techniques on Sentry and the analysis vessel Atlantis, the group was capable of efficiently 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,” stated 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.”
In the course of the expedition, the group additionally captured pictures of a U.S. Navy Avenger torpedo bomber coaching plane that crashed close to the identical space in 1950. Scientists launched video and pictures of the plane, displaying a severely broken tail and a bent entrance propeller.

The group carried out seven dives of the F-1 wreck website and the superior sonar techniques had been capable of produce detailed maps of the submarine and surrounding seafloor. Scientists additionally used high-resolution cameras to seize close-up video of the wreck.
Specialists then used all the info to sew collectively “photogrammetric models capable of providing precise measurements of the sub and the animals that have colonized its wreckage over the years.” That allowed consultants to reconstruct the F-1 submarine and produce gorgeous 3-D fashions of the wreck.
After the dives, the group held a remembrance ceremony on board Atlantis, ringing a bell 19 occasions—one for every crew member misplaced at sea.
“History and archaeology are all about people and we felt it was important to read their names aloud,” stated underwater archaeologist Brad Krueger, who participated within the dives. “The Navy has a solemn responsibility to ensure the legacies of its lost Sailors are remembered.”
