G/ATOR is capable of providing real-time, 360° situational awareness to allow troops to detect and respond to modern threats, including fixed-wing aircraft, helicopters, cruise missiles and unmanned autonomous systems (UAS).

Before a new system is introduced to the fleet, it is put through a rigorous phase of testing IOT&E to test its effectiveness.

Successful completion of the IOT&E demonstrates the viability and suitability of the system.

“We have been able to successfully achieve the IOT&E milestone and begin fielding this radar system with unrivalled mission capability to operational units.”

It will also enable the USMC to operate and field G/ATOR Blocks 1 and 2 in their current configuration.

Northrop Grumman land and avionics C4ISR vice-president Christine Harbison said: “Through our close partnership with the Marine Corps, we have been able to successfully achieve the IOT&E milestone and begin fielding this radar system with unrivalled mission capability to operational units.

“We are proud to deliver hardware enabled, software-defined advanced ground radar systems that meet our customer’s mission needs, protect the warfighter in a rapidly changing threat environment, and have a significant margin for capability growth.”

In July last year, the company delivered the first AN/TPS-80 G/ATOR equipped with advanced high-power and high-efficiency gallium nitride (GaN) antenna technology.

GaN systems were used for development test (DT) 1E1, DT1E2 and IOT&E

Northrop Grumman has so far delivered eight production systems to the Marine Corps. In 2017, the service received six low-rate initial production systems.
