Donald Trump has replaced an experienced admiral with a 33-year-old with no naval experience.

A 33-year-old DOGE employee was tapped to run the U.S. Navy’s science and technology arm, though she appears to have no experience with the U.S. Navy, science, or technology, The Bulwark reported Thursday.

Dr. Rachel Riley was chosen to replace Rear Admiral Kurt Rothenhaus as chief of naval research, where he has served since 2023. The Office of Naval Research is responsible for disbursing billions of dollars in grants and contracts to benefit the Navy, and has historically been led by an active duty flag officer, according to USNI News.

Riley previously worked as a partner at McKinsey & Company, and completed a Ph.D. in social policy and an M.Sc. in contemporary Chinese from Oxford, according to her LinkedIn. She joined the ranks at DOGE and was assigned to the Department of Health and Human Services, where Politico reported she pushed for massive layoffs earlier this year.
