Dental capabilities include: endodontics, oral surgery, crown and bridge, operative and preventative dentistry. The ship's dental staff consists of one dental officer and four dental technicians and is augmented when troops are embarked, by an additional dental officer and dental technician from Camp Pendleton, Ca.

Engineering Department

The true heart of ESSEX is the Engineering Department. These hard working professinals provide steam to propel the ship and power electrical generators, as well as maintain damage control and auxiliary systems.

The two Main Propulsion divisions, MP-1 and MP-2, are responsible for the forward and aft main machinery rooms. Comprised of Boiler Technicians (BTs) and Machinist's Mates (MMs), they not only perform complex emergent repairs on various machinery while deployed, but find the time to complete extensive space preservation efforts. The Oil Lab's skilled and professional performance ensure the smooth and safe transfer millions of gallons of fuel.

The Auxiliary (A Gang) division keeps the air conditioning plants cold, the small boats purring, and the elevators cycling. The MMs, Enginemen (ENs) and Electrician's Mates (EMs) form a cohesive unit that maintain, operate, and repair countless pieces of equipment throughout the ship. This job is essential to not only the primary missions of the ESSEX, but also to the health and comfort of the crew. Hot water and cold air conditioning were a must to keep the crew cool and happy.

Electrical (E) division, manned by EMs, provides power throughout the ship, and maintains navigational equipment essential for safe steaming. By performing numerous repairs for other ships operating with ESSEX, they ably demonstrated that no repair was too large to accomplish.

Executive Department

Executive Department's primary mission is "Customer Service". Executive Department is similar to a city hall staff. Office Clerks, known as Yeoman and Personnelmen, maintain the records and files that enable the city (ESSEX) to operate. All official correspondence is routed through and distributed by this department. The Executive Department staff also supports ESSEX and all embarked units in the following areas: career counseling, drug and alcohol abuse prevention, legal, safety, physical security, printing and maintenance, and material & management (3M). Educational programs, ranging from Navy advancement tests to college course credits, are also coordinated through this department. These essential services are performed by a varied and talented group of individuals from their chosen occupations.

Navigation Department

Navigation Department is comprised of two of the oldest ratings in the Navy, namely the QM and SM ratings. Their main jobs are to ensure the safe passage of ESSEX in her travels, and all external visual communications with other naval and merchant vessels. Even thought the two ratings have very different job descriptions, the department has come together as one team, each lending a distinct capability to the department as a whole. Whether it is shooting bearings while entering or leaving port, sending tactical signals to maneuver the ships in the Amphibious Ready Group or laying tracks to take the crew to far away destinations, the professionals in ESSEX' Navigation Department can be relied upon to provide the best service in the Fleet.

Operations Department

The Operations Department is the focal point for planning coordination and execution of ESSEX missions. These missions range from complex LCAC and Flight Deck operations in support of amphibious exercises and nationally tasked operations, to underway replenishments and integrated training to prepare the ship for any contingency. The department encompasses the Combat Information Center, the true nerve center of the ship and the entity which affects each operational mission. The Operations Department also includes the Helicopter Direction Center, which expertly maintains the fluidity of a demanding flight plan and controls over 30 aircraft that are integral to Navy/Marine Corps missions. The Joint Intelligence Center and Ship's Signals Exploitation Space are also under the Operations Department's umbrella. JIC and SSES collect, analyze and disseminate vital information concerning existing threats, geopolitical climate and military conditions to allow Navy and Marine warfighters to perform their missions with minimal risk. The Operations Department's Meteorological Center is capable of charting weather activity and determining how weather conditions will affect ESSEX operations.
