National Park Service and Autodesk Carry Out First Comprehensive Digital Survey to Preserve the USS Arizona and Memorial
**Public Company Information:**
NASDAQ: ADSK
**HONOLULU – (BUSINESS WIRE)** – In recognition of U.S. military veterans, the National Park Service (NPS) and Autodesk, Inc. (NASDAQ:ADSK) held a press conference today to reveal early findings from the first comprehensive survey of the USS *Arizona* and its accompanying Memorial in three decades. The survey also resulted in the creation of detailed 3D models.
In keeping with Autodesk's mission to empower people to imagine, design, and create a better world, the project leverages cutting-edge technology for both historic preservation and public education. Scheduled for completion later this year, the survey aims to offer the public a more vivid understanding of this iconic historical site while aiding in its ongoing conservation efforts.
At today's Memorial Day event, attendees got their first look at a 3D-printed replica of the USS *Arizona*. This model showcased previously unseen details in striking clarity. Additionally, intricate 3D models of a galley cooking pot and a Coke bottle, both relics that have remained on the ship since the attack 72 years ago, were unveiled. These models included fine textures like barnacles on the cooking pot and even the original colors of the objects. Autodesk and the NPS aspire to complete a full-scale 3D model of the USS *Arizona* by the end of the year.
"This technological approach breathes new life into the legacy of the USS *Arizona*, something we couldn't achieve before," remarked National Park Service Superintendent Paul DePrey. "As stewards of this national treasure, the NPS is committed to sharing the story of December 7th with future generations. By creating these 3D models, we’re giving people the ability to see and interact with highly accurate replicas—a key part of our educational outreach."
Among those present at the press conference was 92-year-old USS *Arizona* survivor Don Stratton, one of only nine surviving members of the ship’s crew. Stratton was just 19 when Pearl Harbor was attacked. That fateful morning, he and six other crew members braved scorching conditions to reach safety aboard the USS *Vestal*. Stratton sustained severe burns covering 70% of his body.
Upon seeing the 3D-printed cooking pot for the first time, Stratton expressed amazement: "That is incredible. I don’t know anyone from the galley who survived that day. It was pure survival after the explosion. Now, looking back, it feels easier to remember. I truly believe these 3D artifacts will leave a lasting impression on many people."
Stratton's son, Randy Stratton, echoed his father’s sentiments: "These artifacts can't be replicated—they symbolize the start and end of the war and remind us that life persists aboard the USS *Arizona*."
Concluding the event, Don Stratton reflected, "I hope everyone remembers the shipmates still aboard the *Arizona*. And I hope they never forget the sacrifices made for this great nation."
It’s estimated that approximately 900 of the 1,777 officers, sailors, and Marines lost aboard the USS *Arizona* remain entombed within the ship. Thus, any work conducted must be carried out with utmost care and respect. Keeping this in mind, the NPS is spearheading efforts to create an exceptionally precise 3D digital representation of the ship while ensuring minimal disruption. To achieve this, the NPS is utilizing Autodesk's reality computing technologies, including underwater photogrammetry, subsea LiDAR, high-resolution SONAR, and above-water laser scanning.
"The USS *Arizona* Memorial is such a vital yet delicate piece of history," noted Brian Mathews, Vice President at Autodesk. "Reality Computing is an emerging field that connects the physical and digital realms. We see immense potential in using this technology to help preserve global heritage sites like the USS *Arizona* and share their stories with future generations."
Collaborating partners on this project include HDR, Sam Hirota, Inc., Oceanic Imaging Consultants, Inc., 3DatDepth, Shark Marine Technologies, Inc., the United States Coast Guard, and the US Navy Mobile Diving Salvage Unit One.
