The challenging missions of NNSA require a highly-skilled and truly dedicated team of physicists, engineers, accountants, analysts, technicians and more. Many team members spend decades of their lives committed to preserving our nation’s security in a variety of ways. When one of our own reaches a major career milestone, we take the opportunity to say, “Thank you for your service.”
Phil Calbos distinguished himself through exemplary service as the Acting Deputy
Administrator for the Office of Defense Programs from July 2016 through October 2018. His mission-driven leadership guided Defense Programs through its most transformative period since the end of the Cold War. His achievements include lasting benefits to the long-term health, safety, and security of the Nation’s nuclear deterrent, as well as the legacy of the Stockpile Stewardship Program.
In recognition of his contributions, he was awarded the Secretary’s Appreciation Award as well as the Administrator’s Gold Service Award. Calbos resumed his position as Principal Assistant Deputy Administrator for Defense Programs after Dr. Charles P. Verdon was sworn in as Deputy Administrator.
