Do you think history has hidden treasures deep in the ocean? A US-based team has completely mapped and filmed the world’s deepest known shipwreck, a World War II US Navy destroyer. the USS Johnston is located in the Philippine Sea, at a depth of 21,180 feet (about 6,500 meters). Even though its location has long been known, this is the first time a crew has been able to map and film the entire wreckage. A private company headquartered in the United States that is called “Caladan Oceanic” which specializes in ocean expeditions discovered the shipwreck on March 31. The company’s exploration ship, the DSV Limiting Factor, examined the wreck, which was discovered to be more than 100 feet deeper than previously thought and lying more than four miles under the surface of the Pacific. Let’s find out more about it.

Victor Vescovo, a retired US Navy commander with a lifelong interest in discovering the world’s most remote places, founded Caladan Oceanic. He is the first person to travel to the top of every continent, both poles, and the bottom of every ocean on the planet. With the survey of the USS Johnston, Vescovo accomplished yet another goal: completing the world’s deepest shipwreck dive. The whole operation took place in two eight-hour parts over two days.

On October 25, 1944, the USS Johnston sank during the Battle of Samar. According to the US Naval History and Heritage Command, it was one of four naval battles that made up the Battle of Leyte Gulf, one of the largest naval battles in history. Former Navy captain and Hawaii Pacific University instructor Carl Schuster, he’s proud of being able to “bring clarity and closure to the Johnston, its crew, and the families of those who fell there.”
