Office of the Chief of Naval Operations

Organizational chart of the Office of the Chief of Naval Operations (OPNAV).

The chief of naval operations presides over the Navy Staff, formally known as the Office of the Chief of Naval Operations (OPNAV).[1][2] The Office of the Chief of Naval Operations is a statutory organization within the executive part of the Department of the Navy, and its purpose is to furnish professional assistance to the secretary of the Navy (SECNAV) and the Chief of Naval Operations (CNO) in carrying out their responsibilities.[3][4]

The OPNAV organization consists of:

Policy documents emanating from the CNO are issued in the form of OPNAV Instructions.

OPNAV is one of the three headquarters staffs in Department of the Navy mainly based at the Pentagon, with the others being the Office of the Secretary of the Navy and Headquarters Marine Corps.

Operating forces

Numbered fleets of the United States Navy

The operating forces consists of nine components:[9]

Fleets in the United States Navy take on the role of force provider; they do not carry out military operations independently, rather they train and maintain naval units that will subsequently be provided to the naval forces component of each

Task Group 60.1.

Numbered fleets

The United States Navy currently has seven active numbered fleets. Various other fleets have existed, but are not currently active.

Numbered Fleet Status Parent Command Geographic Region Notes
1st Fleet Inactive Pacific Fleet N/A The First Fleet was created in 1947. It was deactivated when the Third Fleet assumed its responsibilities in early 1973.[11] The United States Coast Guard is sometimes believed to act as the First Fleet in wartime; however, the United States has never officially used this reference and it is informal at best.[12]
2nd Fleet Active Fleet Forces Command Western North Atlantic Ocean The Second Fleet was redesignated from the Second Task Fleet in 1950 as part of the then-
United States Atlantic Fleet. It was deactivated in 2011,[13]
then reactivated on 4 May 2018.
3rd Fleet Active Pacific Fleet Eastern Pacific Ocean The Third Fleet was active during World War II and was deactivated in 1945. It was reactivated in early 1973 when it assumed the responsibilities previously assigned to the First Fleet.[11]
4th Fleet Active Naval Forces Southern Command Southern Atlantic Ocean The Fourth Fleet was active during World War II and deactivated in 1950 when its responsibilities passed to Second Fleet. It was reactivated in 2008.
5th Fleet Active Naval Forces Central Command Persian Gulf, Red Sea, and part of Indian Ocean The Fifth Fleet was deactivated in 1947 after serving during World War II. It was reactivated in 1995 to assume responsibilities in the Persian Gulf previously assigned to Seventh Fleet.
6th Fleet Active Naval Forces Europe Eastern North Atlantic Ocean and Mediterranean The Sixth Fleet was redesignated from Sixth Task Fleet in 1950 and has been continuously active in the Mediterranean since 1950.
7th Fleet Active Pacific Fleet Western Pacific Ocean & Indian Ocean The Seventh Fleet was activated in 1943, redesignated Naval Forces Western Pacific in 1947, Seventh Task Fleet in 1949 and to its current designation in 1950.
8th Fleet Inactive Atlantic Fleet N/A The Eighth Fleet was established in 1943 from Northwest African Force. It operated in the Mediterranean Sea during World War II, with its forces briefly reassigned to Twelfth Fleet. From 1946-47 served as the heavy striking arm of the
United States Atlantic Fleet before being redesignated Second Task Fleet and later Second Fleet.[14]
9th Fleet Inactive Atlantic and Pacific N/A Before 15 March 1943, Commander, U.S. Naval Forces Europe served as Commander Task Force 99, of the 9th Fleet, which was under the direct command of Admiral King.
Naval Forces Far East
used 90-series task forces in Korea.
10th Fleet Active Fleet Cyber Command Global The Tenth Fleet was active during World War II and reactivated in 2010 for assignment to Fleet Cyber Command.[17]
11th Fleet Inactive Pacific Fleet and Atlantic Fleet N/A Redesignated on 15 August 1943 from 9th Fleet and subsequently transferred to Atlantic Fleet
12th Fleet Inactive Naval Forces Europe N/A The Twelfth Fleet was active in European waters during World War II. It was redesignated United States Naval Forces Mediterranean in 1946, which later became Sixth Task Fleet.[18]

Additional numbered fleets have existed; for a period after World War II, the Sixteenth and Nineteenth Fleets were assigned as the reserve elements for Atlantic and Pacific Fleets.[19]

Organization

The organization of the Navy has changed incrementally over time. During World War II administrative organization for many ship types included divisions, for example

Battleship Divisions (abbreviated BatDivs), Cruiser Divisions, Destroyer Divisions, or Escort Divisions (CortDivs, also rendered ComCortDiv for Commander, Escort Division), usually composed of two ships, often members of the same class. These made up squadrons (e.g. Battle Squadron, Cruiser Squadron, Escort Squadron (CortRon) etc.) of several divisions. Yet the exigencies of World War II forced the creation of the task force
system where ships no longer fought solely as part of same-type divisions or squadrons. This was gradually reflected in administrative arrangements; by the 1970s, formations such as Cruiser-Destroyer Groups (CruDesGrus) came into existence.

The Navy is currently organized as such:

Kuwait Naval Base
.

The Navy maintains several "Naval Forces Commands" which operate naval shore facilities and serve as liaison units to local ground forces of the Air Force and Army.[citation needed] Such commands are answerable to a Fleet Commander as the shore protector component of the afloat command. In times of war, Commander Naval Forces Korea becomes a Task Force (Task Force 78) of the United States Seventh Fleet. Other Naval Force Commands may similarly augment to become number fleet task forces.

The Shore Establishment

  • "The shore establishment provides support to the operating forces (known as "the fleet") in the form of: facilities for the repair of machinery and electronics; communications centers; training areas and simulators; ship and aircraft repair; intelligence and meteorological support; storage areas for repair parts, fuel, and munitions; medical and dental facilities; and air bases."[22]

The following shore-based bureaus, commands and components are directly subordinate to the Chief of Naval Operations:"[22]

Relationships with other service branches

United States Marine Corps

VMFA-451 prepares to launch from the USS Coral Sea (CV-43)

Per sections 8001(a)(2), 8061, 8061(4), and 8063 of title 10, U.S. Code, the United States Marine Corps is (1) a separate branch of the naval service from the U.S. Navy; (2) the Department of the Navy and the U.S. Navy are distinct legal entities; (3) is, along with the U.S. Navy (and U.S. Coast Guard, when assigned) a component of the Department of the Navy; and (4) a branch of U.S. military service, separate from the U.S. Navy, within the Department of the Navy. Furthermore, per sections 8001(a)(1), 5061(4), and 5062(a) of title 10, U.S. Code, (1) the United States Navy does not include the United States Marine Corps (2); the U.S. Marine Corps is a separate component service, from either the U.S. Navy or the U.S. Coast Guard within the Department of the Navy; and (3) the U.S. Marine Corps is not a component of the U.S. Navy.[clarification needed]

The relationship extends to the operational theater as well. As amphibious assault specialists, Marines often deploy on, and attack from, Navy vessels; while being transported on Navy ships, they must obey the orders of the captain of the vessel. Marine aviation

hospital corpsmen or medical doctors; thus officers and enlisted sailors from the Navy fulfill these roles. They generally wear Marine uniforms that are emblazoned with Navy insignia and markings to distinguish themselves from Marines. Corpsmen and chaplains enjoy a great sense of camaraderie with the Marines due in part because they work closely with them and often are embedded with Marine units. They operate under the command of the Marine Corps under the auspices of the Fleet Marine Force, often called the "green side".[24]

Because of the lack of full-scale amphibious operations in recent conflicts, there has been pressure to cut the "gator navy" below the two-regiment requirement of the Marines.

Marine Expeditionary Brigades and actual structure of 2.07 MEB equivalents in 1999.[26]

The relationship between the US Navy and US Marine Corps is also one of mutual respect, and that respect is manifested in various policies and procedural regulations. For example, per US Marine and Navy drill manuals, in a formation consisting of both Marine and Navy units, per MCO P5060.20, Marine Corps Drill and Ceremonies Manual, Paragraph 15001. "ARRANGEMENT OF UNITS IN FORMATION 1. In ceremonies involving the U.S. Marine Corps and U.S. Navy units, the Marine unit shall be on the right of line or head of the column. The senior line officer, regardless of service, functions as the commander of troops." (As this is a Department of Defense/Department of the Navy regulation, no further 10 U.S. Code authority, other than already cited above, is required for the Secretary of the Navy, who supervises both the U.S Navy, and the U.S. Marine Corps, as well as the U.S. Coast Guard whenever it is assigned to the Department of the Navy, to specify that the Marine Corps takes precedence over the Navy and Coast Guard in Naval formations, parades, and ceremonies. This same military precedence is specified in DoD Instruction 1005.8 and U.S. Navy Regulations, Chapter 10, Paragraph 1007.) This is a symbol of the special status and honor granted to US Marines, and is a unique aspect of the Navy-Marine relationship.

United States Coast Guard

Although the

Department of Homeland Security.[27] At other times, Coast Guard Port Security Units are sent overseas to guard the security of ports and other assets. The Coast Guard also jointly staffs the Navy's Naval Coastal Warfare Groups and Squadrons (the latter of which were known as Harbor Defense Commands until late-2004), which oversee defense efforts in foreign littoral combat and inshore areas. Additionally, Coast Guard and Navy vessels sometimes operate together in search and rescue
operations.
