The '''deputy secretary of defense''' ([[acronym]]: '''DepSecDef''') is a statutory office ({{UnitedStatesCode|10|132}}) and the second-highest-ranking official in the [[United States Department of Defense|Department of Defense]] of the United States of America.
The deputy secretary is the principal civilian deputy to the [[United States Secretary of Defense|secretary of defense]], and is appointed by the [[President of the United States|president]], with the advice and consent of the [[United States Senate|Senate]]. The deputy secretary, by statute, is designated as the DoD chief management officer and [[Civilian control of the military|must be a civilian]], at least seven years removed from service as a [[commissioned officer]] on active-duty at the date of appointment.<ref name="UnitedStatesCode|10|132">{{UnitedStatesCode|10|132}}.</ref>
The current deputy secretary of defense is [[Kathleen Hicks]], effective February 8, 2021. Hicks is the first woman to serve in this role.
==History==
Public Law 81–36, April 2, 1949, originally established this position as the ''[[Under Secretary of Defense|under secretary of defense]]'', however Public Law 81-2 16, August 10, 1949, a.k.a. the 1949 Amendments to the [[National Security Act of 1947]], changed the title to deputy secretary of defense. Former assistant to President [[Franklin D. Roosevelt]], [[Stephen Early]], became the first officer holder when he was sworn in on May 2, 1949.<ref name="DODKO:15">[[#DODKO|Department of Defense Key Officials 1947–2015]]: p. 15.</ref>
Public Law 92-596, October 27, 1972, established a second deputy secretary of defense position, with both deputies performing duties as prescribed by the secretary of defense.  The second deputy position was not filled until December 1975. [[Robert Ellsworth]], serving from December 23, 1975, until January 10, 1977, was the only one to ever hold that office. Public Law 95-140, October 21, 1977, established two ''[[Office of the Secretary of Defense|Under Secretaries of Defense]]'' and abolished the second deputy position.<ref name="DODKO:15"/>
==Responsibilities==
By delegation, the deputy secretary of defense has full power and authority to act for the [[United States Secretary of Defense|secretary of defense]] and to exercise the powers of the secretary of defense on any and all matters for which the secretary is authorized to act pursuant to statute or executive order.<ref name="DODKO:15"/> The deputy secretary is first in the line of succession to the secretary of defense.
The typical role of the deputy secretary of defense is to oversee the day-to-day business and lead the internal management processes of the $500-billion-plus Department of Defense budget, that is as its ''[[chief operating officer]]''; while the secretary of defense as the ''[[chief executive officer]]'' focuses on the big issues of the day, ongoing military operations, high-profile congressional hearings, attending meetings of the [[United States National Security Council|National Security Council]], and directly advising the president on defense issues.
Prior to February 1, 2018, the deputy secretary of defense also served as the department's chief management officer, to whom the deputy chief management officer reported, but those responsibilities were split into a new [[Chief Management Officer of the Department of Defense|chief management officer of the Department of Defense]] position (disestablished on 1 January 2021).<ref name=":2">{{Cite web|url=https://www.acq.osd.mil/fo/docs/Section-901-FY-2017-NDAA-Report.pdf|title=Report to Congress: Restructuring the Department of Defense Acquisition, Technology and Logistics Organization and Chief Management Officer Organization|date=August 1, 2017|access-date=February 22, 2018}}</ref>
The deputy secretary, among the office's many responsibilities, chairs the ''[[Senior Level Review Group]]'' (SLRG), before 2005 known as ''Defense Resources Board'' (DRB), which provides department-wide budgetary allocation recommendations to the Secretary and the President. Traditionally, the deputy secretary has been the civilian official guiding the process of the ''[[Quadrennial Defense Review]]'' (QDR).
The deputy secretary of defense chairs the ''Special Access Program Oversight Committee'' (SAPOC), which has oversight responsibilities and provides recommendations with respect to changes in status of the Department's [[Special Access Program]]s, for either the deputy secretary defense or the secretary of defense to make.
As [[James Mattis]] was selecting officials as [[Donald Trump]]s first Secretary of Defense, [[Michèle Flournoy]] talked with Trump-affiliated officials about joining as deputy secretary. She did not in the end do so.
