=== Radars ===
GaN technology is also utilized in military electronics such as [[active electronically scanned array]] radars.<ref>[http://www.spacewar.com/reports/Gallium_Nitride_Based_Modules_Set_New_180_Day_Standard_For_High_Power_Operation_999.html "Gallium Nitride-Based Modules Set New 180-Day Standard For High Power Operation."] ''Northrop Grumman'', 13 April 2011.</ref>

[[Thales Group]] introduced the [[Ground Master 400]] radar in 2010 utilizing GaN technology. In 2021 Thales put in operation more than 50,000 GaN Transmitters on radar systems.<ref>{{Cite web|last=Pocock|first=Chris|title=Export Market Strong for Thales Ground Radar|url=https://www.ainonline.com/aviation-news/defense/2016-02-12/export-market-strong-thales-ground-radar|access-date=2021-05-28|website=Aviation International News|language=en}}</ref>

The [[United States Army|U.S. Army]] funded [[Lockheed Martin]] to incorporate GaN active-device technology into the [[AN/TPQ-53 Quick Reaction Capability Radar|AN/TPQ-53]] radar system to replace two medium-range radar systems, the [[AN/TPQ-36 Firefinder radar|AN/TPQ-36]] and the [[AN/TPQ-37 Firefinder radar|AN/TPQ-37]].<ref name="mwrf.com">{{cite web |last1=Brown |first1=Jack |title=GaN Extends Range of Army's Q-53 Radar System |url=https://www.mwrf.com/defense/gan-extends-range-army-s-q-53-radar-system |website=Microwaves&RF |access-date=23 July 2019|date=16 October 2018 }}</ref><ref>{{cite web |last1=Martin|first1=Lockheed |title=U.S. Army Awards Lockheed Martin Contract Extending AN/TPQ-53 Radar Range |url=https://news.lockheedmartin.com/2018-10-08-U-S-Army-Awards-Lockheed-Martin-Contract-Extending-AN-TPQ-53-Radar-Range |website=Lockheed Martin |access-date=23 July 2019}}</ref> The AN/TPQ-53 radar system was designed to detect, classify, track, and locate enemy indirect fire systems, as well as unmanned aerial systems.<ref>{{cite web |last1=Martin|first1=Lockheed |title=AN/TPQ-53 Radar System |url=https://www.lockheedmartin.com/en-us/products/tpq-53.html |website=Lockheed Martin |access-date=23 July 2019}}</ref> The AN/TPQ-53 radar system provided enhanced performance, greater mobility, increased reliability and supportability, lower life-cycle cost, and reduced crew size compared to the AN/TPQ-36 and the AN/TPQ-37 systems.<ref name="mwrf.com"/>

Lockheed Martin fielded other tactical operational radars with GaN technology in 2018, including [[FPS-117#AN/TPS-77|TPS-77 Multi Role Radar System]] deployed to [[Latvia]] and [[Romania]].<ref>{{cite web |last1=Martin |first1=Lockheed |title=Lockheed Martin Demonstrates Mature, Proven Radar Technology During U.S. Army's Sense-Off |url=https://news.lockheedmartin.com/2019-06-18-Lockheed-Martin-Demonstrates-Mature-Proven-Radar-Technology-During-U-S-Armys-Sense-Off |website=Lockheed Martin |access-date=23 July 2019}}</ref> In 2019, Lockheed Martin's partner [[Elta Systems|ELTA Systems Limited]], developed a GaN-based [[EL/M-2084|ELM-2084]] Multi Mission Radar that was able to detect and track air craft and ballistic targets, while providing fire control guidance for missile interception or air defense artillery.

On April 8, 2020, [[Saab AB|Saab]] flight tested its new GaN designed [[Active electronically scanned array|AESA]] [[X band|X-band]] radar in a [[Saab JAS 39 Gripen|JAS-39 Gripen]] fighter.<ref>{{cite web |url=https://saab.com/gripen/news/blog/gripen-blog/2020/gripen-cd-flies-with-saabs-new-aesa-radar-for-the-first-time/ |title=Gripen C/D Flies with Saab's new AESA Radar for the First Time |archive-url=https://web.archive.org/web/20200502142704/https://saab.com/gripen/news/blog/gripen-blog/2020/gripen-cd-flies-with-saabs-new-aesa-radar-for-the-first-time/ |archive-date=2020-05-02}}</ref> Saab already offers products with GaN based radars, like the [[Giraffe radar]], [[Erieye]], [[GlobalEye]], and Arexis EW.<ref>{{cite web |url=https://saabgroup.com/media/stories/stories-listing/stories-of-innovation/innovation-prize/ |title=Saab first in its industry to bring GaN to market |archive-url=https://web.archive.org/web/20160206010619/https://saabgroup.com/media/stories/stories-listing/stories-of-innovation/innovation-prize/ |archive-date=2016-02-06}}</ref><ref>{{cite web |url=https://saabgroup.com/media/news-press/news/2018-04/saabs-giraffe-1x-radar-offers-a-man-portable-75km-detection-range/ |title=Saab's Giraffe 1X Radar Offers a Man-Portable 75km Detection Range |archive-url=https://web.archive.org/web/20200823213125/https://saabgroup.com/media/news-press/news/2018-04/saabs-giraffe-1x-radar-offers-a-man-portable-75km-detection-range/ |archive-date=2020-08-23}}</ref><ref>{{cite web |url=https://saabgroup.com/media/news-press/news/2018-12/saab-receives-swedish-order-for-giraffe-4a-and-arthur-radars/ |title= Saab Receives Swedish Order for Giraffe 4A and Arthur Radars |archive-url=https://web.archive.org/web/20181205183526/https://saabgroup.com/media/news-press/news/2018-12/saab-receives-swedish-order-for-giraffe-4a-and-arthur-radars/ |archive-date=2018-12-05}}</ref><ref>{{cite web |url=https://saabgroup.com/media/stories/stories-listing/2020-07/outsmarting-threats-by-electronic-attack/ |title=Arexis - Outsmarting threats by electronic attack |archive-url=https://web.archive.org/web/20200823214914/https://saabgroup.com/media/stories/stories-listing/2020-07/outsmarting-threats-by-electronic-attack/ |archive-date=2020-08-23 }}</ref> Saab also delivers major subsystems, assemblies and software for the  [[AN/TPS-80 Ground/Air Task Oriented Radar|AN/TPS-80 (G/ATOR)]]<ref>{{cite web |url=https://www.saab.com/newsroom/press-releases/2015/saab-to-supply-key-components-in-support-of-the-u.s.-marine-corps-groundair-task-oriented-radar-gator-program |title=Saab to Supply Key Components in Support of the U.S. Marine Corps Ground/Air Task Oriented Radar (G/ATOR) Program |archive-url=https://web.archive.org/web/20201031164750/https://www.saab.com/newsroom/press-releases/2015/saab-to-supply-key-components-in-support-of-the-u.s.-marine-corps-groundair-task-oriented-radar-gator-program |archive-date=2020-10-31 |url-status=live |date=Feb 12, 2015}}</ref>

India's [[Defence Research and Development Organisation]] is developing [[Uttam AESA Radar#Virupaakhsha|Virupaakhsha]] radar for [[Sukhoi Su-30MKI]] based on GaN technology.
