Autodesk - National Park Service and Autodesk Carry Out First Comprehensive Digital Survey to Preserve the USS Arizona and Memorial
“This technological approach helps make the USS Arizona’s legacy come alive that just wasn’t possible before,” said National Park Service Superintendent Paul DePrey. “The USS Arizona is one of America’s most revered historical sites. As its steward, the National Park Service has a mission to share the story of December 7 with current and future generations. Creating 3D models allows people to see and touch these highly detailed and accurate replicas, something that will play an important role in our educational outreach program.”
Also present at the press conference was 92-year-old USS Arizona survivor Don Stratton, one of only nine remaining USS Arizona survivors still alive, and one of only a few hundred to make it off the ship. Stratton was only 19 years old when Pearl Harbor was attacked. He along with six other crew members went hand over hand on a heaving line across the burning deck to safety on the USS Vestal that was moored alongside the USS Arizona that fateful morning. Stratton suffered burns over 70 percent of his body.
When presented with the 3D print of the cooking pot for the first time, Stratton said, “That is amazing. I don’t know anybody in the galley that survived that day. At the time of the explosion, it was self-preservation. After that, it was extremely hard to return. Now, when I go back and remember, it’s a little easier. I think it [3D artifacts] will make an impression on a lot of people, I really do.”
Stratton’s son Randy Stratton, who was also present, said, “You can’t duplicate these artifacts. They represent the beginning of the war, the end of the war and the fact that there is still life there [on the USS Arizona].”
Don Stratton concluded, “I hope they remember all the shipmates that are still aboard the Arizona. And I hope they remember all the people that gave their lives for this great country.”

A team of U.S. Navy and supporting company operators and photographers carried out underwater dives  documenting the photogrammetry technique used underwater in Pearl Harbor Hawaii last week.
Below is a quick video of the vie capturing photos of the USS Arizona and USS Utah as well as Shaan Hurley of Autodesk explaining how we at Autodesk were using photogrammetry using Autodesk ReCap Photo and 3D Printing as well as SONAR and LiDAR technologies to capture the iconic ships in 3D to use in education, preservation, and research.

Technology has changed a lot since the last survey.

At a time when more and more flashy, high-tech discoveries and salvage of long- lost undersea wrecks occur, this submerged cultural resource study of the Arizona Memorial is a refreshing change. The combined experience of the National Park Service's Submerged Cultural Resources Unit and the Navy's Mobile Diving and Salvage Unit One is remarkable, they are as expert at their business as can be found. What stands out, though, is that these talented divers sought and brought back for us all not artifacts, not souvenirs, not booty - simply knowledge. After the years of meticulous studies, foot-by-foot inspection and recording -- the USS ARIZONA and its sister ships all still rest secure, exactly as they were before this energetic endeavor began. You, too, can rest assured that these historic undersea relics will remain unimpaired. This is a classic study of how under- sea explorations ought to be done so as to leave their historic subjects intact. In this publication, you have a thoughtful sum- mary of the knowledge they gleaned.
