Northrop Grumman Delivers First Gallium Nitride G/ATOR System to Marine Corps

GatorPhotoBALTIMORE — Northrop Grumman Corp. 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, the company announced in a July 26 release. 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 multimission AESA [Active Electronically Scanned Array] radar that incorporates this advanced GaN technology,” said Roshan Roeder, vice president, land & avionics 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 AESA multimission 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, and rockets, artillery and mortar. It is rapidly deployable worldwide to meet Marine Corps needs and includes the latest cyber and digital beam forming technology that enables the radar to perform multimission tasks at significantly lower operation and maintenance costs compared to existing Marine radar systems.
