Initial production

Northrop Grumman Corporation has delivered the first AN/TPS-80 Ground/Air Task-Oriented Radar (G/ATOR) that incorporates advanced high power and high efficiency Gallium Nitride (GaN) antenna technology, further improving the system’s operational capabilities. This system was delivered ahead of schedule and is the seventh G/ATOR system delivered in the Low Rate Initial Production (LRIP) phase of the program.

GaN technology provides cost savings and multiple performance benefits including enhanced system sensitivity and increased reliability. All subsequent G/ATOR LRIP and full rate production systems will now incorporate this advanced GaN technology.

Delivery of the first GaN G/ATOR system follows the delivery of six LRIP systems to the Marines that began in early 2017. Utilizing two of those six systems, the Marine Corps achieved G/ATOR Initial Operational Capability (IOC) of the air surveillance mission in February of this year. The remaining four systems will establish IOC for the counter-battery mission later this year. As a result, G/ATOR systems, trained Marines and associated logistics support are now in operational service with Marines.

«The Marine Corps are the first to take delivery of a production ground based multi mission AESA radar that incorporates this advanced GaN technology», said Roshan Roeder, vice president, land & avionics Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) division, Northrop Grumman. «The incorporation of this advanced technology in production radars is unique to the Marine Corps and enables G/ATOR to provide additional mission capability to the warfighter at an affordable cost».

Both the Marine Corps and Northrop Grumman continue to make detailed preparations to successfully execute the full rate production program, which is scheduled to begin in early 2019.

Additionally, given the AN/TPS-80’s open architecture design, Northrop Grumman was awarded a contract through the Office of Secretary of Defense Strategic Capabilities Office in 2016 to support the addition of a fire control mission.

The AN/TPS-80 G/ATOR is an advanced Active Electronically Scanned Array (AESA) multi-mission radar that provides comprehensive real time, 360-degree situational awareness against a broad array of threats including fixed wing aircraft, helicopters, cruise missiles, Unmanned Autonomous Systems (UAS), and rockets, artillery and mortar. It is rapidly deployable worldwide to meet United State Marine Corps (USMC) needs and includes the latest cyber and digital beam forming technology that enables the radar to perform multi-mission tasks at significantly lower operation and maintenance costs compared to existing USMC radar systems.

Initial Integration
Testing

Northrop Grumman Corporation and the U.S. Marine Corps successfully completed an Initial Integration Event (IIE) in November 2016 for the AN/TPS-80 Ground/Air Task-Oriented Radar (G/ATOR) system.

«The volley fire capability that G/ATOR demonstrated is critical on the modern battlefield, and all of the data collected during IIE indicates that GWLR can exceed the U.S. Marine Corps’ range capability»,” said Roshan Roeder, vice president, mission solutions, Northrop Grumman

The three-week IIE demonstrated G/ATOR’s Ground Weapon Locating Radar (GWLR) mode’s ability to detect and track multiple types of Rocket, Artillery and Mortar (RAM) rounds simultaneously. Over 40 different weapon scenarios were evaluated through the live fire event, and more than 700 live shots were fired, including a variety of RAM rounds. GWLR successfully tracked projectiles including volley fire between 3.7 miles/6 km and 31 miles/50 km, demonstrating G/ATOR’s long range capability. Volley fire capability is the ability to detect and track multiple RAM projectiles intentionally fired in very rapid sequence in an attempt to overwhelm radar capabilities.

«GWLR mode detects and tracks time-critical incoming threats, calculates an approximate impact point, and then tracks the threat’s trajectory back in time to estimate a firing position, allowing counterfire forces to engage rapidly», said Roshan Roeder, vice president, mission solutions, Northrop Grumman. «The volley fire capability that G/ATOR demonstrated is critical on the modern battlefield, and all of the data collected during IIE indicates that GWLR can exceed the U.S. Marine Corps’ range capability».

The AN/TPS-80 G/ATOR system is multi-mission, performing four principal missions using the same hardware: short-range air defense, tactical air operations control, counterfire target acquisition (GWLR mode) and future air traffic control. GWLR mode adds software to the G/ATOR system to detect, track and identify RAM projectiles, both 360-degree and sector-only. The GWLR mode addresses multiple types of simultaneous threats. Adding this capability will allow G/ATOR to replace five legacy United States Marine Corps (USMC) radars.
