The OS Rating
The Radarman rating, first established in 1943, was disestablished in 1971 with the responsibilities delved out to the Electronic Technician, and the newly established, Operations Specialist and Electronic Warfare Technician ratings.
On September 29, 2016, the Navy moved away from traditional ratings to an alphanumeric system of Navy Occupational Specialty (NOS) codes. For OS, the NOS is B440.
Operations Specialists operate radar, navigation, and communications equipment in combat information centers on the ship's bridge. They detect and track ships, aircraft, and missiles.
Operations Specialist class "A" school is 12 weeks long, and the school is located in Great Lakes, Illinios. The OS rating requires a 60 month (5 year) service obligation.
Operations Specialist (NOS B440)
Operations Specialists 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. OSs operate surveillance and altitude radars' Identification Friend or Foe (IFF), and associated equipment. They serve as air traffic controllers for helicopters and fixed-wing supersonic jet aircraft.
OS's serve as watch supervisors and section leaders, and they interpret and evaluate presentations and tactical situations and make recommendations to supervisors during watch conditions. They 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.
Operations Specialists 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.
Upon completion of the required rating courses, OSs will be able to plot a ship's position, heading, and speed. They operate common marine electronic navigation instruments including radar systems, and provide target plotting data to the combat information center based on information received from target tracking devices.
