Ground/Air Task Oriented Radar (G/ATOR)
Abstract
The Ground/Air Task Oriented Radar (G/ATOR) is a multi-role, ground-based, expeditionary 3D radar system employed by both the Air Combat Element and Ground Combat Element within the Marine Air Ground Task Force. It satisfies the Marine Air Command and Control System and the Ground Counter Fire/Counter Battery capabilities. G/ATOR provides mobile, multi-functional, three-dimensional surveillance of air breathing targets, detection of cruise missiles, unmanned aerial systems, rockets, artillery and mortars, and the cueing of air defense weapons. G/ATOR contributes to Littoral Operations in a Contested Environment and Expeditionary Advanced Base Operations by surveillance and detection of enemy air threats not seen by Navy sensors in the littorals and participating in a cooperative engagement network of sensors and shooters. G/ATOR enables integrated fire control (IFC) and provides engage/fire on remote capability. G/ATOR surveillance coverage with IFC will provide unprecedented reach, volume, and precision in the execution of Operational Maneuver From The Sea allowing Naval forces to project and sustain power deep inland. G/ATOR is the primary ground-based sensor for the United States Marine Corps, and is the only air defense/air surveillance radar currently in the Marine Corps inventory.

- Change Summary Explanation
- FY 2025 funding decrease of $3.068M is primarily due to completion of development of the Radar Signal Processor (RSP). Budget reflects funding required to continue to support the development and integration of software required to implement the full spectrum of Naval Integrated Fire Control (NIFC), the continuation of the Ground Weapons Locating Radar user improvements identified during DT/OT and IOT&E testing, Multi-Domain Radar in a Contested Environment (MuDRaCE), a new Digital Receiver/Exciter (DREX), Mode S, and G/ATOR Block IV (GB4) Expeditionary Airfield Surveillance Radar (EASR) development, while continuing to pursue software capability improvements providing both Low, Slow, Small (LSS) target detection and Non-Cooperative Target Recognition (NCTR).
