On The Same Expedition That Located The Submarine, Team Locates Military Plane Missing Since The 1950s

In the dark silence of the ocean, where one would not imagine it could be, Researchers from the United States Navy and the Woods Hole Oceanographic Institute (WHOI) managed to find the wreckage of an American submarine that sank in 1917 during a training accident in the midst of World War I.

The USS F-1 submarine, which had disappeared during a military exercise, was located — intact — off the coast of California, at more than 400 meters deep.

Fatal Collision And A Century Of Mystery

According to reports, the submarine sank in December 1917, after colliding with the USS F-3 during a training exercise. In the tragedy, 19 crew members died and three managed to survive. Since then, the area has been treated as a “war grave” and, therefore, the wreckage has not been disturbed. The hull, lying on its side, remains surprisingly intact!

In the 1970s, the Navy estimated the general location of the accident, but only now has technology allowed for the precise identification of the exact point.

Delicate Mission, Historic Outcome

Using cutting-edge technology, such as the submersibles Alvin and Sentry, the team formed by the United States Navy and the Woods Hole Oceanographic Institute (WHOI) successfully mapped the area in ultra-high resolution and confirmed the identity of the sunken vessel.

“When the divers went down and saw the structure so clearly, it was like going back in time,” said Bruce Strickrott, leader of the Alvin Group. “No one expected it to be so well preserved.”

Another Unexpected Find: A Lost Military Plane

During the same expedition, the team also came across the wreckage of a Grumman TBF Avenger, a plane used by the Navy in training, that crashed in 1950. Although the accident was already known, the exact position of the aircraft remained unknown.

This time, the ending was less tragic: all occupants of the plane survived. And a curious detail caught attention — the number “13” still visible on the fuselage, feeding old military superstitions that, despite everything, seem not to have been confirmed in this case.
