On December 17, 1917, the USA-1 submarine lost at sea during a training accident off the California coast, killing 19 crew members on board. Now, a few days before the anniversary, the scientists announced that they had taken unprecedented pictures of the final place of rest in the era of World War I more than 1300 feet below the surface of the ocean
High-resolution images were taken for USS F-1 after a group of sales teams between agencies used advanced developed imaging technology during an exploratory period earlier this year, according to what it said. press release From Woods Hole Institution.
UsS F-1 collided with her sister’s ship, USS F-3, during the Oean surface training off San Diego eight days before Christmas in 1917, according to Power of submarine and museum association. The USS F-1 was drowned in only 10 seconds, and five of the 24 staff were rescued. The association said that the subcontractor was lost nearly 60 years ago until it was located by a deep-seat virtual vehicle looking for a flying fighter that crashed in 1972.
“It looked like a large ax had hit it,” said Lieutenant Dave Magear, a pilot of the purpose that discovered USS F-1. A story from 1976. But it was not possible to do a closer survey given the depth of the submarine.

With the help of the Maritime Research Office (ONR), the history of history and marine heritage (NHHC) and the National Science Corporation, and the Woods Hall Foundation team for ocean sciences is a vehicle that is operated by two thousand, as well as a far -place underwater vehicle called Sentry Sentry to take pictures closely.
Using Sonar Systems on Sentry and ATLANTIS Research, the team enables accurate surveys in the submarine.
“As soon as we identified the wreckage and decided that it was safe to dive, we were able to capture unprecedented views of the subcontractor,” said Bruce Striprot, the chief pilot who helped lead the campaign. “As a veteran in the US Navy, it was a deep honor to visit the F-1 wreck with our colleagues on ONR and NHHC on two thousand.”
During the campaign, the team also took pictures of the Torbid bomber training plane in the US Navy, which crashed near the same area in 1950. Scientists launched a video and pictures of the plane, indicating a tail that was severely damaged and a bent front fan.

The team conducted seven dies from the F-1 site and the advanced Sonar systems managed to produce detailed maps of the submarine and the surrounding sea. Scientists also used high -resolution cameras to take a closer video of debris.
Specialists then used all data to stitches “Photogrammetric models capable of providing accurate measurements for the branch and animals that have colonized their wreckage over the years.” This allowed experts to rebuild the F-1 submarine and produce amazing 3D models of debris.
After diving, the team held a memory ceremony on the Atlantis, and a 19 -time bell is ranging – one for each crew member lost at sea.
“History and antiquities revolve around people and we felt it is important to read their names loudly,” said Brad Kruger, an underwater archaeologist, who participated in diving. “The navy bears an official responsibility to ensure remembering the heritage of the missing sailors.”
