On 17 December 1917, USS F-1 collided with its sister ship, USS F-3, off the coast of San Diego during a training exercise in dense fog. The impact caused the F-1 to sink within ten seconds, resulting in the loss of 19 crew members. A mere five sailors survived the incident. The submarine now rests approximately 1,300ft (~396m) beneath the Pacific Ocean.
