Ship's company

A ship's company comprises all officers, non-commissioned officers and enlisted personnel aboard a naval vessel. The size of the ship's company (the complement) is the number of people on board, excluding civilians and guests.

An exception to this rule is the definition of ship's company as it applies to U.S. Navy and U.S. Marine Corps personnel assigned to aircraft-capable ships of the U.S. Navy, primarily aircraft carriers and amphibious assault ships.

In the case of aircraft carriers of the U.S. Navy, the total ship's complement is divided into three categories:

(1) the ship's company physically assigned to the ship, and
(2) the carrier air wing, with its associated strike fighter, Marine fighter/attack, electronic attack, airborne early warning and helicopter squadrons, which is considered a separate "embarked" command, and
(3) the carrier strike group commander and staff, which is also considered an "embarked" command
