Duties
The Radarman rating was changed to Operations Specialist in October 1972, with its operational duties assigned to the OS rating, electronic warfare operation and maintenance to the Electronic Warfare Technician, and its radar maintenance duties to the Electronics Technician rating.
Operations Specialists play an important role with search-and-rescue teams, such as man overboard and directing search-and-rescue helicopters to downed pilots at sea.
The Operations Specialist also operates radar, navigation, and communications equipment in shipboard and combat information centers or bridges. They detect and track ships, planes, and missiles. They operate and maintain IFF systems.
Since changing from RD to OS, the OS rating has taken on more functions or duties. Besides Radar navigation, tactical communications, naval gunfire support, and Air Intercept Control, the OS now directs amphibious operations, establishes and maintains tactical data links, Anti-Submarine Tactical Air Control, Strike control, and other duties.
