Sean Stackley is a retired United States Navy officer and senior United States Department of Defense civilian official who served as Acting United States Secretary of the Navy and as Assistant Secretary of the Navy (Research, Development and Acquisition). He led major acquisition programs, oversaw shipbuilding portfolios, and guided weapons and systems development across the Department of the Navy. His tenure intersected with high-profile programs involving the Arleigh Burke-class destroyer, Virginia-class submarine, and other naval platforms.
Born in 1957, Stackley graduated from the United States Naval Academy with a Bachelor of Science in 1979, joining a cohort that produced numerous naval leaders and flag officers linked to institutions such as Naval War College and United States Naval Academy Class of 1979. He later earned a Master of Science in Mechanical Engineering from the Massachusetts Institute of Technology and completed postgraduate studies at the University of Phoenix. His educational background connected him with academic networks including MIT Department of Mechanical Engineering, Naval Postgraduate School alumni, and research collaborations with entities like Office of Naval Research and Defense Advanced Research Projects Agency.
Stackley served as a United States Navy officer from 1979 to 2012, holding engineering and program management billets that interfaced with the Naval Sea Systems Command, Fleet Readiness Center, and shipyards such as Norfolk Naval Shipyard and Puget Sound Naval Shipyard. He worked on platform acquisition and sustainment programs related to the Nimitz-class aircraft carrier, Ticonderoga-class cruiser, and Littoral Combat Ship programs, collaborating with prime contractors including General Dynamics, Huntington Ingalls Industries, and Lockheed Martin. His naval career included assignments that brought him into contact with organizations such as the Chief of Naval Operations, Commander, Naval Sea Systems Command (NAVSEA), and program executive offices that manage systems like the Phalanx CIWS and AN/SPY-1 radar.
After retiring from active duty, Stackley served in senior civilian roles within the Department of the Navy, culminating in his appointment as Acting United States Secretary of the Navy. He held the position of Assistant Secretary of the Navy for Research, Development and Acquisition, overseeing acquisition authorities tied to the Defense Acquisition University framework and interacting with congressional committees including the United States Senate Committee on Armed Services and the United States House Committee on Armed Services. In these capacities he worked alongside officials from the Office of the Secretary of Defense, Under Secretary of Defense for Acquisition and Sustainment, and senior leaders such as former Secretaries who shaped procurement and requirements, including counterparts from Pentagon offices.
Stackley led policy initiatives on shipbuilding affordability, modernization of combat systems, and integration of unmanned systems. He implemented reforms that affected programs like the Zumwalt-class destroyer, Ford-class aircraft carrier, and the modernization pathways for the Mk 41 Vertical Launching System. His leadership engaged industry partners such as Boeing, Northrop Grumman, and Raytheon Technologies on sensors, weapons integration, and life-cycle maintenance. Stackley promoted initiatives that intersected with acquisition statutes including the Federal Acquisition Regulation and worked with oversight entities such as the Government Accountability Office on program reviews. He championed workforce development efforts linked to institutions like the Defense Acquisition University and technology transitions involving Naval Research Laboratory and Strategic Systems Programs stakeholders.
Stackley received awards and recognitions reflecting his service in the United States Navy and civilian leadership in the Department of the Navy. His decorations include service awards commonly granted by the Department of Defense and unit recognitions associated with commands such as NAVSEA and fleet commands tied to the United States Pacific Fleet and United States Fleet Forces Command. He has been acknowledged by professional societies and trade associations in defense acquisition circles, including groups connected to National Defense Industrial Association and Armed Forces Communications and Electronics Association.
Stackley is married and has family ties that are part of communities associated with Navy installations such as Naval Station Norfolk and Naval Base San Diego. His personal affiliations include professional memberships and alumni networks from the United States Naval Academy, MIT Alumni Association, and acquisition communities that intersect with organizations like the American Society of Naval Engineers.
Stackley’s legacy rests on stewardship of Navy acquisition during a period of platform transition and modernization. His decisions influenced the trajectories of programs including the Virginia-class submarine procurement profile, surface combatant survivability upgrades tied to Aegis Combat System evolutions, and the sustainment philosophies for Naval Aviation platforms like the F/A-18 Hornet and successors. Analysts and historians examining naval procurement link his tenure to debates involving shipbuilding industrial base stability, cost control measures, and the integration of emerging technologies from entities like DARPA and Naval Research Laboratory. His impact continues to be referenced in discussions by defense committees, industry consortia, and academic studies in institutions such as Johns Hopkins University and Massachusetts Institute of Technology that assess defense acquisition reform.
