Overview of the Salvage Operation
On October 3, 2025, the U.S. Navy, in collaboration with the Pearl Harbor National Memorial, successfully removed significant portions of two World War II-era mooring platforms from the USS Arizona. This operation was part of a broader effort to preserve the historic battleship, which serves as a war grave for over 900 Sailors and Marines who perished during the attack on Pearl Harbor on December 7, 1941.
Details of the Operation
The salvage operation commenced on September 3, 2025, following two years of meticulous planning and analysis to ensure compliance with relevant laws and regulations. The U.S. Navy Mobile Diving and Salvage Unit (MDSU) 1, supported by local contractors, undertook the task of removing the platforms, which had a combined weight exceeding 150 tons. The operation was completed within a month, with the team prioritizing operational safety and environmental best practices throughout the process.
MDSU-1 personnel employed methodical techniques to cut into the concrete platforms, while cranes were utilized to lift the segments onto barges for removal. The operation effectively reduced the weight on the Arizona's deck, leaving only minimal portions of the platforms to avoid disturbing the ship's structure, which includes features believed to be embedded in the concrete.
Official Statements & Responses
Capt. Lee Shannon, commander of Task Force Arizona, expressed pride in the team's efforts, noting, “A great deal of effort from dozens of subject matter experts, both on and off the water, resulted in a successful salvage operation.” Cmdr. Matthew Englehart, U.S. Pacific Fleet diving and salvage officer, emphasized the operation's significance, stating, “Our number one priority was to protect the USS Arizona for the future.” He highlighted that the weight of the platforms posed a threat to the ship's integrity, and their removal was essential for preserving the memorial.
Bill Manley, Navy Region Hawaii environmental director, reiterated the Navy's commitment to protecting both the USS Arizona and the environment during the operation.
Why It Matters
The removal of the platforms is a proactive measure aimed at safeguarding the USS Arizona as it continues to age. This operation not only alleviates structural stress on the memorial but also honors the sanctity of the site, which is a vital piece of American history. The USS Arizona Memorial, built in 1962, is accessible only by boat and rests above the sunken remains of the battleship, managed by the National Park Service since 1980.
