Preserving History - US Navy Douglas TBD-1 Devastator

3D at Depth Inc., the world’s leading expert in subsea LiDAR laser technology and 3D data solutions, has successfully integrating photogrammetry with Subsea laser LiDAR (SL) technology to create reverse engineered 3D models. The technique was developed during an October 2018 expedition with the Air/Sea Heritage Foundation to document the largely intact wreck of a rare and historically significant US Navy Douglas TBD-1 Devastator aircraft resting at the bottom of Jaluit Lagoon in the Republic of the Marshall Islands (RMI). Of the 129 Devastators built, all were either lost in battle, destroyed in operational accidents, or scrapped before the end of World War II. This particular expedition was developed to capture precise, repeatable, millimetric data to build an accurate 3D model as a 21st century site map for this significant cultural heritage asset; and to serve as a “pre-disturbance survey” for the proposed recovery, conservation and public exhibition of the historic plane at the National Museum of
