Rediscovering History: the USS Independence

Thirty miles off the coast of San Francisco, CA, at  793 m (2,600 ft) depth, lies the watery grave of the decorated United States aircraft carrier, Independence.

Built in New Jersey (1942), the USS Independence was built for speed; the first of a new class of carriers designed from converted cruiser hulls. In January, 1943, the new carrier joined active service vessels in the midst of World War II. The Independence began her military career shortly after arriving in Pearl Harbor, HI, in July of 1943, joining the USS Essex and USS Yorktown for a devastating raid on Marcus Island. Afterwards, the Independence  participated in the attacks on Rabaul, Tarawa, Luzon, and Okinawa.

At war’s end, the Independence transported veterans home from the Pacific front in Operation Magic Carpet. She received eight battle stars for her service in the war, and was recognized for sinking the Japanese battleship, Musashi, during the Battle of the Philippines. Before her decommissioning in August of 1946, the Independence  was assigned as a target vessel for the Bikini atomic bomb tests for Operation Crossroads atomic bomb tests in Bikini Atoll, Marshall Islands. On July 1 and 25, 1946 the Independence was positioned just a half-mile from ground zero. She sustained heavy damage from shock waves, heat and radiation, but did not sink. The US Navy towed the damaged carrier back to San Francisco for decontamination. In 1951, the Independence met her watery grave when she was scuttled off the coast of San Francisco.

Sixty-four years later, in March of 2015, NOAA’s Office of National Marine Sanctuaries (ONMS), Ocean Exploration and Research (OER), and the Naval History and Heritage Command (NHHC) positively identified the USS Independence wreck site. Scientists were able to construct a 3-D sonar image of the wreck using autonomous underwater vehicle (AUV), Echo Ranger. They found the Independence surprisingly intact, with a possible plane in the forward aircraft elevator hatch opening.

On August 22, 2016, Dr. Robert Ballard and the crew of the E/V Nautilus began a series of exploratory dives on the Independence wreck using remotely operated vehicles (ROVs), Hercules and Argus. These USS Independence dives are part of Nautilus‘s expedition to explore the Greater Farallones National Marine Sanctuary and Monterey Bay National Marine Sanctuary off the coast of California. Using teleprescence technologies, viewers around the world were able to participate in the rediscovery of this proud ship.
