Dustin Blosmo, the chief engineer with VRC Metal Systems, repairs the side of a Martin Marietta HGM-25A Titan I with a mobile Cold Spray machine in Dock 43 at Ellsworth Air Force Base, S.D., June 22, 2017. With this technology, maintainers are able to repair thinner metals that traditional welding would not be able to do, allowing them to restore previously unrepairable objects.
