The Surface Technical Ratings assignments branch supports Navy Personnel Command's mission of putting "the right sailor in the right place at the right time!" This branch consists of ET, FC, GM, MN, OS, and STG Detailers.
Electronics Technician (ET) are responsible for electronic equipment used to send and receive messages, computer information systems, long range radar, and calibration of test equipment. They maintain, repair, calibrate, tune, and adjust electronic equipment used for communications, detection and tracking, recognition and identification, navigation.
Fire Controlman (FC) The Navy's Advanced Electronics / Computer Field offers extensive training in all aspects of electronics including computer systems, radars, communications systems and weapons fire control systems such as the Navy's advanced missile system, Aegis. Only two Navy job specialties, called "ratings", are included in the Advanced Electronics / Computer Field: Electronics Technician (ET) and Fire Controlman (FC). The rating in which an Advanced Electronics / Computer Field candidate is trained is determined in the initial phase of the Advanced Electronics Technical Core Course in Great Lakes, Ill. However, eligibility requirements are the same for both ratings in the Advanced Electronics / Computer Field. ETs maintain and repair electronics equipment such as radar, communication and navigation equipment. The ET and FC (AEF) ratings comprise the basis of the ship's Combat Systems department aboard ships and are responsible for maintaining the ship's readiness for combat operations.
Gunner’s Mate (GM) are responsible for the operation and maintenance of guided missile launching systems, gun mounts and other ordnance equipment, as well as small arms and magazines. They work with electrical and electronic circuitry; mechanical, hydraulic and pneumatic systems.
Mineman (MN) perform their duties at sea aboard minesweepers assisting in the detection and neutralization of underwater mines. Ashore, minemen are technicians who test, assemble and maintain underwater explosive devices (mines). They test various electronic components to ensure proper repair and make sure that the mine works properly. They are also responsible for safe storage, handling and loading of mines for transporting.
Operations Specialist (OS) function as plotters, radio-telephone and Command and Control sound-powered telephone talkers and maintain Combat Information Center (CIC) displays of strategic and tactical information. Operate surveillance and altitude radars Identification Friend or Foe (IFF), and associated equipment. Serve as Air Traffic Controllers for helicopters and fixed-wing supersonic jet aircraft. Serve as watch supervisors and section leaders; interpret and evaluate presentations and tactical situations and make recommendations to supervisors during watch conditions. Apply a thorough knowledge of doctrine and procedures applicable to CIC operations contained in U. S. Navy Instructions and Allied or U.S. Navy Publications and procedures necessary for radar navigation contained in Naval Oceanographic Office publications. Provide to the command technical information and assistance related to Anti-Surface Warfare, Anti-Air Warfare, Anti-Submarine Warfare, Amphibious Warfare, Mine Warfare, Naval Gunfire Support, and search and rescue operations, and other matters pertaining to the Operations Specialist's area.
Sonar Technician (STG) performs the duties of Identify, Classify, Track, and when necessary destroy subsurface threats. They do this from Surface Combatants (DDG's, CG's, FFG's, and LCS's), SURTASS Ships, Aircraft carriers, and various ashore sites throughout the world. They are responsible for underwater surveillance, and aid in safe navigation and search and rescue operations. They use sonar to detect, analyze and locate targets of interest.
