United States Secretary of the Navy

The Department of the Navy (DoN) consists of two uniformed services: the United States Navy and the United States Marine Corps.^[4] The secretary of the Navy is responsible for, and has statutory authority (10 U.S.C. § 8013) to "conduct all the affairs of the Department of the Navy", i.e. as its chief executive officer, subject to the limits of the law, and the directions of the president and the secretary of defense. In effect, all authority within the Navy and Marine Corps, unless specifically exempted by law, is derivative of the authority vested in the secretary of the Navy.

Specifically enumerated responsibilities of the SECNAV in the aforementioned section are: recruiting, organizing, supplying, equipping, training, mobilizing, and demobilizing. The secretary also oversees the construction, outfitting, and repair of naval ships, equipment, and facilities. SECNAV is responsible for the formulation and implementation of policies and programs that are consistent with the national security policies and objectives established by the president or the secretary of defense.^[5][6]

The secretary of the Navy is a member of the Defense Acquisition Board (DAB), chaired by the Under Secretary of Defense for Acquisition, Technology and Logistics. Furthermore, the secretary has several statutory responsibilities under the Uniform Code of Military Justice (UCMJ) with respect to the administration of the military justice system for the Navy & the Marine Corps, including the authority to convene general courts-martial and to commute sentences.

The principal military advisers to the SECNAV are the two service chiefs of the naval services: for matters regarding the Navy the chief of naval operations (CNO), and for matters regarding the Marine Corps the commandant of the Marine Corps (CMC). The CNO and the Commandant act as the principal executive agents of the SECNAV within their respective services to implement the orders of the secretary.

Navy Regulations

The United States Navy Regulations is the principal regulatory document of the Department of the Navy, and all changes to it must be approved by the secretary of the Navy.

U.S. Coast Guard

Whenever the United States Coast Guard operates as a service within the Department of the Navy, the secretary of the Navy has the same powers and duties with respect to the Coast Guard as the secretary of homeland security when the Coast Guard is not operating as a service in the Department of the Navy.^[7]

The Office of the Secretary of the Navy, also known within DoD as the Navy Secretariat or simply just as the Secretariat in a DoN setting, is the immediate headquarters staff that supports the secretary in discharging his duties. The principal officials of the Secretariat include the under secretary of the Navy (the secretary's principal civilian deputy), the assistant secretaries of the Navy (ASN), the general counsel of the Navy, the judge advocate general of the Navy (JAG), the Naval inspector general (NIG), the chief of Legislative Affairs, and the chief of naval research. The Office of the Secretary of the Navy has sole responsibility within the Department of the Navy for acquisition, auditing, financial and information management, legislative affairs, and public affairs.^[8]

Pursuant to SecNavInst 5090.5F, the Department of the Navy Environmental Programs Manual, the secretary of the Navy and chief of naval operations recognize a number of commands annually for achievements in such areas as environmental quality, environmental cleanup, natural resources conservation, cultural resources management, pollution prevention, and recycling.^[9]

The chief of naval operations and the commandant of the Marine Corps have their own separate staffs, the Office of the Chief of Naval Operations (also known by its acronym OPNAV) and Headquarters Marine Corps.
