Numbered fleets
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 a period after World War II, the Sixteenth and Nineteenth Fleets were assigned as the reserve elements for Atlantic and Pacific Fleets.
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 Division
A BatDiv or BATDIV was a standard U.S. Navy abbreviation or acronym for "battleship division." The Commander of a Battleship Division was known, in official Navy communications, as COMBATDIV (followed by a number), such as COMBATDIV ONE.
World Wa ...
s (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:
*
U.S. Fleet Forces Command / Naval Forces Northern Command
**Type commands, including
Submarine Force U.S. Atlantic Fleet, Surface Forces Atlantic, and Naval Air Forces Atlantic
**
Second Fleet operates in the Atlantic Ocean from the North to South Pole, from the Eastern United States to Western Europe and Africa, and along both the eastern and western shores of Central and South America. Second Fleet is the sole operational fleet within
Fleet Forces Command, providing force training and exercises of assigned maritime forces and providing combat-ready Naval forces to support Service missions and global requirements. Second Fleet works with the Combined Joint Operations from the Sea/Center of Excellence to complete its mission.

They generally wear Marine uniforms that are emblazoned with Navy insignia and markings to distinguish themselves from Marines.

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 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.
