Lockheed Martin, is already exporting ground-based GaN radars (AN/TPS-77s) to Romania and Latvia. Last year, Lockheed got contracts to build GaN radars for the Space Fence project tracking orbital hazards and to build a GaN Long-Range Discrimination Radar (LRDR) for the Missile Defense Agency.
As for Raytheon, besides upgrading AN/TPY-2, the company is using GaN in the Air & Missile Defense Radar (AMDR) on the future Flight III upgrade of the Navy’s Arleigh Burke destroyers. It’s also offering a GaN radar upgrade for the famous and widely exported Patriot missile defense system.
And lets not forget Northrop Grumman with the TPS-80 G/ATOR.
