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 B420 (ET), B310 (FC), B311 (FC Aegis), B320 (GM), B230 (IC), C160 (MN), B440 (OS), and B340 (STG) Detailers.
Maintenance and Material Management (3-M) Coordinators at Sea (3MC) Are there no in-rate billets available for you at sea? Are you a highly motivated leader and desire increased responsibility and challenge? Do you desire an assignment to a specific geographical area? Consider assignment as a 3MC. Contact your detailer to determine your eligibility. Remember – your detailer must release you to the 3MC Detailer before he (the 3MC Detailer) can discuss specific duty station assignments with you. Check out the 3MC webpage for additional information.
B420-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.
B310/B311-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.
