The structure of the United States Navy consists of four main bodies: the Office of the Secretary of the Navy , the Office of the Chief of Naval Operations , the operating forces (described below), and the Shore Establishment.
30-572: The U.S. Fleet Cyber Command is an operating force of the United States Navy responsible for the Navy's information network operations, offensive and defensive cyber operations, space operations and signals intelligence. It was created in January 2010 "to deter and defeat aggression and to ensure freedom of action to achieve military objectives in and through cyberspace". U.S. Tenth Fleet
60-617: 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)
90-584: A period after World War II, the Sixteenth and Nineteenth Fleets were assigned as the reserve elements for Atlantic and Pacific Fleets. 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
120-526: A task force structure aligned to the U.S. Tenth Fleet. U.S. Fleet Cyber Command is also designated as the Joint Force Headquarters-Cyber to U.S. Pacific Command and U.S. Southern Command for the development, oversight, planning and execution of full spectrum cyber operations aligned with other traditional warfighting lines of operation. U.S. Fleet Cyber Command's roots are in the namesake of its force provider, U.S. Tenth Fleet, which
150-458: Is a formally documented lawful order that is issued by the Chief of Naval Operations . These instructions are typically used to establish United States Navy policy, procedures, and requirements. The instructions are issued in the form of a memorandum on official Department of the Navy letterhead . Each instruction is referenced with an OPNAVINST directive number and a date. Typically, when
180-505: 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. The OPNAV organization consists of: Policy documents emanating from the CNO are issued in the form of OPNAV Instructions . OPNAV is one of
210-854: Is a unique aspect of the Navy-Marine relationship. Although the Posse Comitatus Act , which prevents federal military personnel from acting in a law enforcement capacity, applies only to the Army and Air Force, Department of Defense rules effectively require the Navy and Marine Corps to act as if Posse Comitatus did apply, preventing them from enforcing Federal law. The United States Coast Guard fulfills this law enforcement role in naval operations. It provides Law Enforcement Detachments (LEDETs) to Navy vessels, where they perform arrests and other law enforcement duties during Navy boarding and interdiction missions. In times of war, or when directed by
240-739: Is currently organized as such: 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. 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 following shore-based bureaus, commands and components are directly subordinate to
270-458: The Chief of Naval Operations :" 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)
300-563: The National Security Agency and Central Security Service . U.S. Fleet Cyber Command also reports directly to the Chief of Naval Operations as an Echelon II command and is responsible for Navy information network operations, offensive and defensive cyberspace operations, space operations and signals intelligence [1] . Headquartered at Fort George Meade, Maryland , U.S. Fleet Cyber Command exercises operational control of globally-deployed Cyber Mission Forces (CMF) through
330-881: The Secretary of the Navy . However, it is considered to be a distinct, separate service branch and not a subset of the Navy; the highest ranking Marine officer, the Commandant of the Marine Corps , does not report to a Navy officer. Marine Corps Medal of Honor recipients are awarded the Navy variant, and Marines are eligible to receive the Navy Cross . The United States Naval Academy trains Marine Corps commissioned officers while prospective Navy officers undergo instruction by Marine NCO Drill Instructors at OCS . Naval Aviation includes Navy and Marine aviators , flight officers , and aircrew . The relationship extends to
SECTION 10
#1732797809448360-666: The Commander, Fleet Cyber Command, has also simultaneously been Commander, Navy Space Command, though the latter post was not formally established until January 2023. Structure of the United States Navy#Operating forces The chief of naval operations presides over the Navy Staff , formally known as the Office of the Chief of Naval Operations ( OPNAV ). The Office of the Chief of Naval Operations
390-485: The Department of Defense computer network attack activities from the Joint Staff. USSPACECOM was eventually dissolved and some its functions merged into the reorganized U.S. Strategic Command (STRATCOM) 1 October 2002. Navy Cyber operations were originally the responsibility of Naval Computer and Telecommunications Command, Naval Security Group and Naval Space Command , which were combined with 20 other commands into
420-564: The Eastern Seaboard for the Mediterranean might start out as Task Group 20.1; on crossing the mid-Atlantic boundary between Fleet Forces Command and United States Naval Forces Europe - Naval Forces Africa , it might become ('inchop') Task Group 60.1. The United States Navy currently has seven active numbered fleets. Various other fleets have existed, but are not currently active. Additional numbered fleets have existed; for
450-518: 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
480-616: The Naval Network Warfare Command (NETWARCOM) in 2002 to unify network operations, offensive and defensive cyberspace operations, space operations and cryptologic/signals intelligences. In 2005, with the alignment of Naval Security Group, NETWARCOM brought the former Naval Security Group Activities (NSGAs) under its umbrella and the mission of the command fundamentally changed, making it the Navy's lead command for information operations, networks and space. After extensive study, Secretary of Defense Robert Gates directed
510-900: The President, the Coast Guard operates as a service in the Navy and is subject to the orders of the Secretary of the Navy until it is transferred back to the Department of Homeland Security . 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. OPNAV Instruction An OPNAVINST or OPNAV Instruction
540-519: 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
570-595: The U.S. Marine Corps is not a component of the U.S. Navy. In 1834, the United States Marine Corps (USMC) came under the Department of the Navy . Historically, the United States Navy has enjoyed a unique relationship with the Marines, partly because they both specialize in seaborne operations. At the highest level of civilian organization, the USMC is part of the Department of the Navy and reports to
600-487: 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,
630-527: The command of the Marine Corps under the auspices of the Fleet Marine Force , often called the "green side". 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. This is a reduction from the programmatic goal of 2.5 Marine Expeditionary Brigades and actual structure of 2.07 MEB equivalents in 1999. The relationship between
SECTION 20
#1732797809448660-568: The creation of a new sub-unified command, U.S. Cyber Command (USCYBERCOM) on 12 November 2008, to operate under the authority of USSTRATCOM. U.S. Fleet Cyber Command was officially created as the Navy component to U.S. Cyber Command on 29 January 2010. Chief of Naval Operations Adm. Gary Roughead named Vice Adm. Bernard J. McCullough III as the commander of both U.S. Fleet Cyber Command and U.S. Tenth Fleet. All subsequent commanders have led U.S. Fleet Cyber Command and U.S. Tenth Fleet simultaneously. In August 2017, President Donald J. Trump announced
690-407: The elevation of USCYBERCOM from a sub-unified command under USSTRATCOM to a Unified Combatant Command responsible for cyberspace operations. U.S. Fleet Cyber Command remains the Navy service component to USCYBERCOM. In April 2019, Navy Space Command (NAVSPACECOM) was established as the service component of the U.S. Space Command , while being commanded by the head of Fleet Cyber Command. Since 2019
720-455: The naval forces component of each Unified Combatant Command . While not widely publicized, groups of ships departing U.S. waters for operational missions gain a Task force type designation, almost always with the Second or Third Fleets. On entry into another numbered fleet's area of responsibility, they are redesignated as a task group from that fleet. For example, a carrier task group departing
750-508: 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 tailhook squadrons train and operate alongside Navy squadrons, flying similar missions and often flying sorties together. Other types of Marine air squadrons operate from amphibious assault ships in support of Marine amphibious operations. Navy and Marine squadrons use
780-510: The same NATOPS aviation manuals and procedures. The USMC does not train chaplains , 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
810-461: 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
840-553: 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 . The operating forces consists of nine components: 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
870-617: Was organized in 1943 to coordinate the allied response to the German U-boat threat and ensure access to the shipping lanes of the Atlantic. Today, U.S. Fleet Cyber Command and the modern U.S. Tenth Fleet ensure the Navy and the Nation have access to systems in the cyber domain. Department of Defense cyber operations came together under a single organization on 1 October 2000, when U.S. Space Command (USSPACECOM) formally took control of
900-450: Was simultaneously reactivated as its force provider. Since it was founded, the command has grown into an operational force composed of more than 16,000 active and reserve sailors and civilians organized into 27 active commands, 40 Cyber Mission Force units, and 27 reserve commands around the world. U.S. Fleet Cyber Command serves as the Navy component command to U.S. Cyber Command , and the Navy's Service Cryptologic Component commander under
