A World War I submarine wreck off the coast of Southern California has been captured for the first time in new video and images made possible using advanced deep-sea imaging technology.
The sunken U.S. Navy vessel now resting on the San Diego seafloor is known as the USS F-1. F-class submarines were based in the Pacific, serving at Hawaii and off California. The F-1 was lost at sea following an accidental collision on December 17, 1917, resulting in the death of 19 crew members. While others were rescued, the submarine sank in just 10 seconds. It was found again nearly 60 years later, according to the Submarine Force Library and Museum Association.
