OPERATIONS SPECIALIST (OS)
The combat information center watchstander — the Navy's shipboard radar, air-control, and tactical-picture rating.

OVERVIEW
Operations Specialist (OS) is the U.S. Navy's shipboard combat-information-center watchstander. OSs operate the radar, identification, and tactical display consoles in the CIC of every U.S. Navy combatant, build the surface, air, and subsurface tactical picture, and provide controllers for naval gunfire support, helicopter control, and Aegis air defense. The rating is the largest combat-systems rating on a destroyer.
OSs feed the Tactical Action Officer the recognized maritime picture in real time, vector strike-group air assets onto threats, and run the navigation plot during sea-and-anchor and restricted-water transits. The senior OS aboard ship — the OS Chief — typically serves as the Combat Systems department's Leading Chief Petty Officer.
The general community covers the U.S. Navy's traditional shipboard ratings — deck, engineering, weapons, and combat-systems Sailors who keep surface combatants and amphibious ships in the fight. Sailors in this community typically rotate between sea and shore tours and are eligible for a wide range of NECs, instructor billets, and enlisted commissioning programs.
A-school for the rating runs ~10 weeks at Naval Air Technical Training Center, NAS Pensacola, FL (and Dam Neck, VA), where Sailors complete the technical foundation needed to report to their first fleet command. Entry requires the ASVAB line score VE+MK+CS=157 and an enlistment obligation of 4–6 years. OSs advance through the standard enlisted paygrade structure (E-1 through E-9), competing in the Navy-Wide Advancement Examination (NWAE) at E-4 through E-6 and via the Selection Board at E-7 through E-9. Senior OSs typically serve as Leading Petty Officer (LPO), Work Center Supervisor, Leading Chief Petty Officer (LCPO), or Command Master Chief (CMC), and may pursue Limited Duty Officer (LDO), Chief Warrant Officer (CWO), or commissioning programs such as STA-21, MECP, or OCS.
Across the active force, OS Sailors are essential to the Navy's mission readiness, and the rating remains an in-demand career field with strong reenlistment bonuses (SRB), advancement opportunities, and pathways into Navy Reserve, civilian DoD, and industry careers after service.
WHAT OSs DO
Operations Specialists stand watch in the Combat Information Center on every U.S. Navy combatant. They operate the SPS-67/SPS-73 surface-search radars, the SPY-1/SPY-6 air-search radars on Aegis ships, the Identification Friend or Foe (IFF) system, and the Aegis Display System or Ship's Self-Defense System consoles. OSs serve as Tactical Information Coordinators (TIC), Surface Tracker, Air Tracker, Helicopter Controller, Naval Gunfire Liaison, and CIC Watch Officer. Ashore they staff Maritime Operations Centers and Fleet Battle Watches.

- Support general military training (GMT), damage control, force protection, and watch-bill assignments common to every Sailor regardless of rating.
HISTORY
Operations Specialist was established in 1972 as a consolidation of the older Radarman (RD) rating with the air-controller and tactical-plotting specialties. The rating absorbed multiple legacy specialties as Aegis and combat-systems automation reshaped shipboard operations through the 1980s and 1990s.
Today the OS rating is at the center of the Navy's shift to networked, multi-mission combat systems, including Aegis Baseline 9, Cooperative Engagement Capability, and the Maritime Tactical Command and Control common operating picture.
Like all surface-Navy general ratings, the rating evolved alongside the U.S. Navy's transition from sail to steam, then steam to gas-turbine and electric-drive propulsion, and continues to adapt to today's distributed maritime operations and integrated combat systems.
Today the Operations Specialist (OS) rating is overseen by the Enlisted Community Management (ECM) office at My Navy HR and the Center for Personal and Professional Development. Modern OSs benefit from the Sailor 2025 personnel-system reforms, the Ready Relevant Learning (RRL) training continuum, and credentialing through the Navy COOL program — turning rating qualifications into industry-recognized certifications and licenses.
The rating's structure, training pipeline, and operational employment continue to evolve alongside the Navy's transition to Distributed Maritime Operations (DMO), Project Overmatch, and the Force Design 2045 fleet architecture, ensuring OSs remain central to the warfighting mission.
