The U.S. Navy’s Office of Naval Research recently worked with operator of the retired WWII-era carrier USS Midway to test a drone-based corrosion detection system.
ONR’s fast-prototyping division, TechSolutions, has developed a sensor package and processing system called “Topside Drone” that can detect corrosion and anomalies on hull surfaces automatically, saving time in surveys. The technology will be used to inspect and detect material defects, corrosion, warping and other forms of deterioration.
