DoD Key Officials 1

Introductory Note

This compilation, prepared by the Historical Office of the Office of the Secretary 

of Defense (OSD), presents information about the Department of Defense (DoD) 

organization and its key officials since its establishment in 1947.

The scope of the work is a Department-wide listing of senior officials, but it does not 

purport to be comprehensive. “Key Officials” is not official terminology, nor is this 

a top-down listing of officials in order of precedence or reporting authority. It lists 

both Presidentially-Appointed, Senate-confirmed (PAS) as well as non-PAS officials. 

It includes civilian officials in the Office of the Secretary of Defense and the military 

departments as well as the top leadership of the Joint Chiefs of Staff (JCS), the 

Combatant Commands, and certain DoD field activities and Defense agencies.

This compilation includes titles of some official positions that have been superseded 

by new titles or organizational changes. The text indicates all instances where this has 

occurred. Where an official position has a direct lineal predecessor with a similar scope 

of functions, the prior position is either included with the current position or the text 

indicates where the prior position can be found elsewhere in the publication.

In most entries, the effective date of incumbency is either the swearing-in date or initial 

appointment date. Officials assume office after being appointed to the positions, usually 

followed by a ceremonial swearing-in days or weeks later. Dates of DoD directives 

establishing the responsibilities of positions and prescribing functions may appear 

months and sometimes years later. Human Resources personnel records, especially for 

the first several decades of the Department, are imperfect. Offices are often without 

a permanent appointee for periods ranging from days to years. During many of these 

periods, there are officials in an “acting” or a “performing the duties of” capacity. In 

other instances, there is no indication of an acting official, and a time gap is evident. 

Since the enactment of the Federal Vacancies Act (VRA) of 1998, as amended, 

designation of acting officials, and the statutory limitations on how long they are 

authorized to use the designation of “acting,” is more closely managed. 

This edition corrects errors that appeared in the 2004 edition and brings the information 

up to date (as of October 2016). Please call any errors that appear in this publication 

to the attention of the Office of the Secretary of Defense Historical Office. A digital 

version of this compilation is updated quarterly at http://history.defense.gov/

IV. Secretaries of the Military Departments

The National Security Act of 1947 established three military departments—the Department of the Army (renaming 

of the former War Department), the Department of the Navy (comprised of the Navy and Marine Corps), and the 

newly created Department of the Air Force. All three were executive departments, each headed by a Secretary. 

The amendments of 1949 (PL 81–216, 10 August 1949) changed the status of the departments from “executive” 

to “military,” the Secretaries thus giving up their seats in the Cabinet and the National Security Council. On 31 

December 1958, the Secretary of Defense issued DoD Directive 5100.1 establishing two command lines, one for 

operational direction of the armed forces through the JCS to unified and specified commands and the second for the 

direction of support activities through the Secretaries of the military departments.

Joint Chiefs of Staff

28 DoD Key Officials

V. Joint Chiefs of Staff

The Joint Chiefs of Staff (JCS), in existence since 1942, gained statutory sanction in the National Security 

Act of 1947. Under this law the JCS initially consisted of the Chief of Staff, U.S. Army; the Chief of Naval 

Operations; the Chief of Staff, U.S. Air Force; and the Chief of Staff to the Commander in Chief, if there should 

be such a position. The act also established a Joint Staff under the JCS, limiting it to 100 officers, to be headed 

by a director appointed by the Joint Chiefs.

The 1949 amendments to the National Security Act of 1947 established the position of Chairman of the Joint 

Chiefs of Staff, to be appointed from the regular officers of the Armed Services for a term of 2 years with 

eligibility for a second 2-year term. The Chairman presided over the meetings of the JCS but did not have a vote. 

Moreover, he was not authorized to exercise military command over the JCS or any of the military services. The 

amendments also increased the size of the Joint Staff to 210 officers.

In 1952, PL 82–416 authorized the Commandant of the Marine Corps to meet with the JCS as a coequal 

whenever any matter of concern to the Marine Corps was under consideration. Subsequently, PL 95–485 (20 

October 1978) made the Commandant a permanent and fully participating member of the JCS.

Reorganization Plan No. 6 of 1953 made the selection and tenure of members of the Joint Staff subject to the 

approval of the Chairman and gave him management control of the Joint Staff. The Department of Defense 

Reorganization Act of 1958 increased the Joint Staff to 400 officers and limited their tours of duty to 3 years 

except in time of war. The act specified that the Joint Staff “shall not operate or be organized as an overall 

Armed Forces General Staff and shall have no executive authority.” The 1958 act also gave the Chairman a vote 

in JCS meetings.

Congress in PL 90–22 (5 June 1967) set the terms of the chiefs of the Army, Navy, Air Force, and Marine Corps 

at 4 years, with provision for possible reappointment for 4 years in time of war or emergency.

The Goldwater-Nichols Department of Defense Reorganization Act of 1986 prescribed the most important 

changes in the JCS organization since 1947. It increased the responsibilities of the Chairman, naming him the 

principal adviser to the President, the National Security Council, and the Secretary of Defense and prescribing 

a 2-year term with possibility of two additional terms (other than during wartime, when there would be no 

limitation). The Chairman’s responsibilities included assisting the President in providing strategic direction of 

the Armed Forces, preparing strategic plans and joint logistic and mobility plans, and advising the Secretary of 

Defense on requirements, programs, and budgets, particularly a budget proposal for activities of each unified 

and specified combatant command.

The act created the position of Vice Chairman of the Joint Chiefs of Staff, to rank after the Chairman and ahead 

of all other officers of the Armed Forces and to come from a service other than that of the Chairman. The Vice 

Chairman could participate in meetings of the JCS, although he was not a member. In the absence or disability 

of the Chairman, the Vice Chairman would replace him. The National Defense Authorization Act for Fiscal Year 

1993, PL 102–484 (23 October 1992) made the Vice Chairman a full member of the JCS. The National Defense 

Authorization Act for Fiscal Year 2012, P.L. 112-81 (31 December 2011) made the Chief of the National Guard 

Bureau a full member of the Joint Chiefs of Staff.

VI. Under Secretaries of Defense

PL 95–0140, 21 October 1977, established the position of Under Secretary of Defense at a level immediately 

below the Deputy Secretary of Defense. The two initial appointees to this rank were the Under Secretary for 

Policy and the Under Secretary for Research and Engineering, the latter replacing the Director of Defense 

Research and Engineering. The Military Reform Act of 1986, PL 99–348, 1 July 1986, established the position 

of Under Secretary for Acquisition as the successor to the Under Secretary for Research and Engineering, with 

enhanced rank (from Executive Level III to Executive Level II) and functions. A few months later, the National 

Defense Authorization Act for Fiscal Year 1997, PL 99–661, 14 November 1986, spelled out in more detail the 

duties of the Under Secretary of Defense (Acquisition). See the Under Secretary listings below for subsequent 

changes in the title of this position.

The National Defense Authorization Act for 1994, PL 103–160, 30 November 1993, established the position of Under 

Secretary of Defense for Personnel and Readiness. The National Defense Authorization Act for 1995, PL 103–337, 

raised the Comptroller to Under Secretary/Comptroller. The National Defense Authorization Act for Fiscal Year 2003, 

PL 107–314, 2 December 2002, established the position of Under Secretary of Defense for Intelligence.

The five current Under Secretary positions are listed by order of precedence.

A. Acquisition, Technology, and Logistics

PL 95–140, 21 October 1977, created the position of Under Secretary of Defense (Research and Engineering) 

to replace the Director of Research and Engineering (see part IX.B.7, Former Assistant Secretary of Defense 

Positions, Research and Engineering, for predecessors of this position). It was succeeded by the Under 

Secretary of Defense (Acquisition) in 1986.

This position was established by PL 99–348 in 1986 as the Under Secretary of Defense (Acquisition) and 

by DoD Directive 5134.1, 10 February 1987. The title changed to Under Secretary of Defense (Acquisition 

and Technology) in NDAA Fiscal Year (FY) 1994 (PL 103–160), 30 November 1993. The National Defense 

Authorization Act for FY 2000 (PL 106–65), 5 October 1999, redesignated the position as the Under Secretary 

of Defense (Acquisition, Technology, and Logistics). He serves as the principal assistant to the Secretary of

Defense and the Assistant Secretaries of Defense as well as a number of positions that are non-Presidentially 

Appointed Senate-Confirmed (PAS) principal staff assistants to the Secretary of Defense. For the sake of 

simplicity, these positions are listed together in this section. The Deputy Chief Management Officer is first in 

order of seniority under the statute governing the composition of OSD and under Executive Order 13533 (1 

March 2010), which establishes the order of succession within DoD.

A. Deputy Chief Management Officers of the 

Department of Defense

This position was established by NDAA FY08, PL 110–181 (28 January 2008). The Deputy Secretary of Defense 

serves as the Chief Management Officer of the Department of Defense and is assisted in this capacity by a 

Deputy Chief Management Officer. The Secretary shall assign such duties and authorities to the Deputy Chief 

Management Officer as are necessary for that official to assist the Chief Management Officer to effectively and 

efficiently organize the business operations of the Department of Defense. The office stood up 9 October 2008 and 

is governed by DOD Directive 5105.82, 17 October 2008. Congress further stipulated in Section 904 of NDAA 

FY09, PL 110–417 (14 October 2008) that the Deputy Chief Management Officer should serve as Vice Chairman 

of the Defense Business Systems Management Committee (DBSMC) and act as Chairman in the Deputy 

Secretary’s absence. Effective October 2001, the Defense Business Council is the subordinate governance board 

to the Deputy’s Management Action Group (DMAG) regarding the management of the Department’s business 

operations in accordance with DoD Directive 5105.79. The DBC is co-chaired by the DCMO of the Department 

of Defense and the DoD Chief Information Office. The Deputy Secretary merged a number of senior leadership 

bodies with the DMAG, including the DBSMC, in late 2011. The Deputy Chief Management Officer ranks 

in precedence just after the Under Secretaries and is paid at the same rate (Level III of the Executive Schedule.

E. Inspectors General of the Department of Defense 

The Department of Defense Authorization Act of 1983, PL 97–252, 8 September 1982, and DoD Directive 

5106.1, 14 March 1983, established the Office of the Department of Defense Inspector General. This position 

replaced the office of Assistant to the Secretary of Defense for Review and Oversight, established in April 1981 

to check fraud, waste, and abuse in procurement. That position and the Defense Audit Service, created in 1976, 

were dissolved when the Office of the Inspector General began operations in May 1983. 

The Inspector General is an independent official who coordinates policies and makes recommendations to further 

economy and efficiency in administration. The Inspector General keeps the Secretary of Defense and Congress informed 

about problems relating to the administration of programs and the possibility of corrective action following investigation.
