DDG 51-Class Departments & Divisions

Although some variation exists between specific ships, the following is represenative of the shipboard organization of ships of the DDG-15 Arleigh Burke class guided missile destroyers. Different ships may have alightly different divisions, but for the most part differences between ships of this class represent variation in the aggregation of Divisions into Departments.


Administrative Department (ADMIN) in the ship is responsible for generating and compiling all of  the instructions and policies that the ship must follow. Additionally, ADMIN handles all official documents produced and received by the Command. ADMIN also provides medical services, counseling services, and a Master-At-Arms Force that maintains good order and discipline in the ship. ADMIN is led by the Executive officer.

PERSONNEL. The Personnelmen (PNs) are responsible for the updating of crew member's service records. These service records include official documents, such as qualification sheets, evaluation reports, and list of awards received. Each record stays with that service member for his or her entire Navy career, and therefore must be extremely accurate, especially when a member transfers. The PNs also assist in ensuring all crew members are paid the correct amount on time.

ADMINISTRATIVE. The Yeomen (YNs) handle all official correspondence, publications, and documents for the Command. Additionally, the YNs are responsible for maintaining officer service records, ensuring entries are current and complete.

CAREER COUNSELING. The ship maintains one Navy Counselor (NC) on board as a resource to crew members. The NC can assist crew members in applying for numerous programs offered by the Navy. Finally, the NC ensures that all reenlistment requests are accurate and acted upon to support crew members' reenlistment wishes.

MASTER-AT-ARMS. The Master-At-Arms (MAs) ensure that good order and discipline is kept by the ship crew members, both on and off the ship. MAs continuously inspect the ship for cleanliness and safety. Additionally, MAs handle the preparation of all discipline reports, and assist the Legal Officer in conducting both judicial and nonjudicial punishment procedures. The MA Force is made up of at least one rated MA, and other crew members who volunteer for the Master-At-Arms Force.

MEDICAL. The ship maintains two Hospital Corpsman (HM) on board to support the crew with medical treatment, and to provide quick response in case of an emergency. The ship's Independent Duty Corpsman (IDC) serves as the ship's "Doc" and, with his assistant, serves as the command's sole resource for both routine and emergency medical care. The Hospital Corpsmen provide care to injured or ill crew members. They are trained to conduct minor medical and dental procedures in the absence of an actual medical doctor. Corpsmen also assist physicians with physical examinations, patient care, and the administration of medication.


The ship's sophisticated combat system is designed to support brief, intense engagements, in which the full simultaneous operational capability of the ship, including maximum firepower of all weapons, will be employed to support national policy. The ship will operate as an element of a coordinated force, or independently as the nucleus of a Surface Action Group (SAG), to conduct and/or coordinate operations in numerous warfare mission areas, including: Anti-Air Warfare (AAW), Anti-Surface Warfare (ASUW), Anti-Submarine Warfare (ASW), and Strike Warfare (STW). Combat System Department, operating by the motto "In God We Trust, All Others We Track..." is led by the Combat System Officer, and consists of 4 divisions.
