It has been fitted with the GaN antenna solution to improve its operational capabilities.

The current system represents the seventh G/ATOR system to be provided during the low-rate initial production (LRIP) phase of the programme.

"The Marine Corps are the first to take delivery of a production ground-based, multi-mission active electronically scanned array (AESA) radar that incorporates this advanced GaN technology."

Northrop Grumman C4ISR division land and avionics vice-president Roshan Roeder said: “The Marine Corps are the first to take delivery of a production ground-based, multi-mission active electronically scanned array (AESA) radar that incorporates this advanced GaN technology.

“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.”

The GaN antenna technology is noted to offer cost savings and multiple performance benefits, including increased system sensitivity and improved reliability.

Northrop Grumman and USMC are currently making detailed preparations to successfully carry out the full-rate production programme, which is scheduled to commence early next year.

The AN/TPS-80 G/ATOR is an advanced AESA multi-mission radar that provides comprehensive real-time, 360° situational awareness against a wide range of threats such as fixed-wing aircraft, helicopters, cruise missiles and unmanned autonomous systems (UAS), along with rockets, artillery and mortar weaponry.

It is equipped with the latest cyber and digital beam-forming technology and is capable of carrying out multi-mission tasks at significantly lower operation and maintenance costs than USMC’s current radar systems.

The AN/TPS-80 radar offers automatic adaptability via a scalable open system architecture, while its multi-network capability ensures compatibility with other command and control systems used by the US Department of Defense (DoD).
