Submarine from World War I uncovered near California coastline by scientists - Submarine from World War I unearthed near California coastline
In a stunning discovery off the coast of San Diego, California, a research team from the Woods Hole Oceanographic Institution (WHOI) has uncovered the remains of the USS F-1, a U.S. Navy submarine deployed during World War I. Using cutting-edge deep-sea imaging technology, they captured unique images of the submarine that has been lost for over a century.
Built in 1912, the USS F-1 was approximately 44 meters long and was powered by diesel engines on the surface and electric motors and batteries when submerged. From 1916, the USS F-1 carried out patrol and training missions off the California coast. However, an accident occurred eight days before Christmas in 1917.
In an unfortunate incident, the USS F-1 collided with its sister ship, the USS F-3, during an exercise at sea off the coast of San Diego. The impact resulted in the USS F-1 sinking in just ten seconds. Only five crew members out of the 24 survived the incident. Afterwards, the submarine was believed to be lost. Although it was briefly located in the 1970s, approaching it and conducting a detailed investigation was impossible due to the extreme depth at that time.
Remarkably intact after 108 years underwater, the USS F-1 lies on its starboard side with its bow pointing northwest. The team, using the manned research submersible Alvin and an autonomous underwater robot named Sentry, managed to capture captivating images of the submarine in early 2025. These images reveal that the USS F-1 is well-preserved, with details such as the propellers and the tower visible. The researchers mapped the submarine wreck and its surroundings using sonar measurements, close-ups, videos, and 3D models created through photogrammetry.
While the depth was no problem for the submersible and autonomous robot, a high level of expertise and advanced equipment were required for this exploration. Moreover, it was essential to approach this submarine wreck with care, as it is also the grave of 19 sailors. A memorial ceremony was held on the deck of the accompanying ship to honor the lost submariners. The ship's bell rang 19 times, once for each of the dead, whose names were read aloud.
In terms of historical significance, the discovery of the USS F-1 provides valuable insights into early U.S. submarine operations. The Navy has a solemn duty to ensure that the memory of its lost sailors is preserved, underscoring the importance of this underwater memorial.
The incredible findings from the USS F-1, discovered off the coast of San Diego, California, have furthered our understanding of early U.S. submarine operations during the first World War. As we delve deeper into the realm of environmental-science and technological advancements, these underwater explorations offer fascinating insights into both history and the resilience of submarines deep in the sea. Moreover, as space-and-astronomy continues to captivate the world, the implementation of such cutting-edge technology may pave the way for future missions, not only in the ocean depths but potentially beyond our planet as well.
