History
[edit]On January 9, 2015 Deputy Secretary of Defense Robert O. Work established the position of Assistant Secretary of Defense (Strategy, Plans, and Capabilities) in accordance with section 906 of the National Defense Authorization Act for Fiscal Year 2010, as amended, PL 111-84, which eliminated all non-presidentially appointed, Senate-confirmed deputy under secretaries of defense. The assistant secretary of defense (strategy, plans, and capabilities) replaced and assumed the responsibilities of the deputy under secretary of defense (strategy, plans, and forces).[3] The assistant secretary of defense (strategy, plans, and capabilities) gained responsibility for advising the secretary of defense and the under secretary of defense (policy) on the development of national security and defense strategy, military planning, budgeting, and various force development, force management, and corporate processes. This position also assumed responsibility for security cooperation, previously managed by the assistant secretary of defense for special operations and low-intesinty conflict.[4]
