USS Arizona Mooring Platforms Removed to Preserve Historic Ship

The U.S. Navy, in coordination with the Pearl Harbor National Memorial, removed significant portions of two World War II-era mooring platforms from the USS Arizona in October 2025 to help preserve the historic ship. This operation aimed to reduce stress on the ship’s deteriorating structure and ensure its long-term preservation as a memorial.

The Significance of the USS Arizona

the USS Arizona holds a uniquely somber place in American history. Sunk during the Japanese attack on Pearl Harbor on December 7,1941,the ship became the final resting place for 1,177 sailors and Marines. The ship remains submerged in Pearl Harbor, and the memorial built over it is one of the most visited historical sites in Hawaii. preserving the Arizona is not simply about maintaining a relic of the past; it’s about honoring the sacrifice of those who perished and ensuring their story continues to be told.

The Removal Operation

The U.S. Navy mobile Diving and Salvage Unit One,supported by local contractors,completed the removal of most of the 80-year-old concrete platforms in approximately one month. The platforms,known as mooring platforms 2 and 3,had been contributing to the ship’s ongoing deterioration. Here’s a breakdown of the process:

• Weight Reduction: The primary goal was to reduce the weight bearing down on the USS Arizona’s deck. Over time,the weight of the concrete platforms had exacerbated corrosion and structural weaknesses.
• careful Demolition: The removal wasn’t a complete dismantling. Minimal portions of the platforms were intentionally left in place to maintain the historical context and avoid further disturbing the wreck.
• Specialized Equipment: Crane barges and specialized diving teams were utilized to carefully extract the concrete sections without causing damage to the ship itself.

Why Remove the Platforms Now?

The decision to remove the platforms was based on extensive monitoring and assessment of the USS Arizona’s condition. Engineers persistent that the continued weight and deterioration of the concrete were accelerating the ship’s decay. Removing the bulk of the platforms stabilizes the wreck and buys time for future preservation efforts. The Navy and National park Service continually monitor the site for changes and potential risks.

Future Preservation Efforts

The removal of the mooring platforms is just one step in a long-term preservation strategy. The National Park Service, which manages the Pearl Harbor National Memorial, is committed to protecting the USS Arizona for future generations. Ongoing efforts include:

• Monitoring Corrosion: Regular inspections and analysis of corrosion rates are crucial for understanding the ship’s condition.
• Water Quality Management: Maintaining the water quality around the wreck helps to slow down corrosion.
• Research and development: Exploring new technologies and techniques for underwater preservation is an ongoing priority.

Key takeaways

• The U.S.Navy and Pearl Harbor National Memorial removed portions of mooring platforms from the USS Arizona to preserve the historic ship.
• The removal reduced weight and stress on the ship’s deteriorating structure.
• this operation is part of a larger, long-term preservation strategy to honor the memory of those lost at Pearl harbor.

The preservation of the USS Arizona is a complex and ongoing undertaking. By proactively addressing the challenges of underwater deterioration, the navy and National Park Service are ensuring that this significant historical site remains a powerful and poignant memorial for years to come.
