AN/TPS-80 G/ATOR

Northrop Grumman
United States

Ground/Air Task-Oriented Radar - multi-mission AESA radar providing air surveillance, air defense, and counter-fire capabilities for Marine Corps operations.

AN/TPS-80 G/ATOR

System Overview

What It Is

The AN/TPS-80 Ground/Air Task-Oriented Radar (G/ATOR) is the Marine Corps' premier multi-mission radar system. Using active electronically scanned array technology, it provides air surveillance, air defense fire control, and counter-fire target acquisition from a single expeditionary platform.

How It Works

G/ATOR uses AESA technology to electronically steer radar beams without mechanical movement, enabling rapid multi-function operation. It can simultaneously track aircraft, cruise missiles, UAS, and incoming artillery while providing fire control quality tracks to air defense systems like MRIC.

Primary Capability

Multi-mission active electronically scanned array radar for air surveillance, air defense, and counter-UAS target acquisition.

Combat Record / Operational History

Fielded with Marine Corps units; primary sensor for MRIC program.

Overview

The AN/TPS-80 G/ATOR represents a generational leap in Marine Corps ground-based radar capability. By consolidating multiple legacy systems into a single multi-mission platform, G/ATOR reduces the logistics burden while dramatically improving operational capability.

Multi-Mission Capability

G/ATOR performs three critical functions:

  1. Air Surveillance: Long-range detection and tracking
  2. Air Defense: Fire control quality tracks for interceptors
  3. Counter-Fire: Locating enemy artillery and mortars

AESA Technology

Active Electronically Scanned Array technology enables:

  • Instantaneous beam steering
  • Multiple simultaneous functions
  • Enhanced electronic protection
  • High reliability with no moving parts

MRIC Integration

G/ATOR serves as the primary sensor for the Medium-Range Intercept Capability (MRIC) program, providing target acquisition and fire control for SkyHunter interceptors.

Counter-UAS Role

For drone defense, G/ATOR provides:

  • Detection of low-RCS UAS targets
  • Track quality sufficient for intercept
  • Integration with C2 systems
  • Persistent surveillance capability

Expeditionary Design

Designed for Marine Corps expeditionary operations, G/ATOR is:

  • Rapidly deployable
  • Operable in austere environments
  • Compatible with amphibious operations
