Northrop Grumman G/ATOR Demonstrates Fire Control Radar Capability for US Marine Corps


Northrop Grumman Corporation’s AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR) multifunction sensor successfully detected and tracked multiple cruise missile threats simultaneously during a recent live-fire test at White Sands Missile Range, New Mexico.


G/ATOR successfully tracked each target immediately after launch and passed relevant information in real time to intercept numerous cruise missile targets from multiple angles. The tests were part of the U.S. Marine Corps’ mid-tier acquisition rapid prototyping effort, known as the Ground Based Air Defense Medium-Range Intercept Capability (GBAD MRIC), a developmental program established to protect high-value areas and assets from airborne threats such as cruise missiles and aircraft.

The rapid emplacement and displacement of the AN/TPS-80 means troops can quickly stand up this mission capability in the field, perform the mission, and rapidly move assets to avoid vulnerability of enemy targeting. Unlike traditional sensors, multifunction systems like G/ATOR consolidate multiple capabilities into a single sensor, decreasing the size, weight and power requirements.


G/ATOR is one piece of the solution providing the joint forces with an operational picture and deep breadth of data to operate in today’s contested environment, in support of the Marine Corps’ Force Design 2030 strategy. The GBAD MRIC program, led by the USMC, integrates existing systems — specifically, G/ATOR and the Common Aviation Command and Control System (CAC2S) — with components of the Israeli Iron Dome System including the Tamir interceptor to provide integrated surveillance and coverage.


“During this test event, the AN/TPS-80 demonstrated a combination of performance capabilities during a realistic representation of an adversary attack,” said Michael Hahn, director, advanced land radar solutions, Northrop Grumman. “G/ATOR is an expeditionary radar and is unrivaled in its ability to simultaneously provide weapons quality tracks on numerous, concurrent airborne targets while maintaining 360-degree surveillance coverage. The software-defined nature of the AN/TPS-80 was critical in rapidly developing and demonstrating this advanced capability in support of challenging threat scenarios to support the Marine Corps.”

The AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR) is the United States Marine Corps next generation Air Surveillance/Air Defense and Air Traffic Control (ATC) Radar. The mobile active electronically scanned array radar system is currently being developed by Northrop Grumman and was expected to reach initial operating capability in August 2016. The Ground/Air Task Oriented Radar (G/ATOR) is a single materiel solution for the mobile Multi-Role Radar System and Ground Weapons Locating Radar (GWLR) requirements. It is a three-dimensional, short/medium range multi-role radar designed to detect unmanned aerial systems, cruise missiles, air breathing targets, rockets, artillery, and mortars. G/ATOR satisfies the warfighter’s expeditionary needs across the Marine Air-Ground Task Force spectrum replacing five legacy radar systems with a single solution.
