Naval career

Commissioned via Boston University Reserve Officers' Training Corps in 1985, Gilday began his career as a surface warfare officer with division officer tours on USS Caron (DD-970), USS Samuel Eliot Morison (FFG-13), and other surface combatants.

Named Chief of Naval Operations in 2019, he led the United States Navy through strategic challenges including high-end training regimes with the Royal Netherlands Navy, operational cooperation with the People's Republic of China in contested waters, and support to allies in the Indo-Pacific Command and European Command theaters. He prioritized advanced warfighting concepts, procurement alignment with the Defense Advanced Research Projects Agency, and partnerships with industry leaders such as Lockheed Martin, General Dynamics, Boeing, and Raytheon Technologies for shipbuilding, sensors, and hypersonic research. During his tenure he worked with the Secretary of the Navy and the Chairman of the Joint Chiefs of Staff on force design, budgetary posture, and personnel reforms.
