The AN/TPS-63 was a medium range, Two-dimensional, L band radar system utilized by the United States Marine Corps from the early 1980s until finally retired in 2018. This mobile radar was developed by Northrop Grumman and complimented the &lt;a href="AN/FPS-117"&gt;AN/TPS-59&lt;/a&gt; long range radar by providing 360 degree, gap-filling coverage of low altitude areas. Because it was more mobile, the TPS-63 was also employed as the first radar ashore during amphibious operations until the larger and more capable AN/TPS-59 was established. The TPS-63 was used in combat operations during the Gulf War, the 2003 invasion of Iraq and subsequent operations in Iraq and Afghanistan. The TPS-63 was eventually phased out of service in 2018 as it was replaced by the &lt;a href="AN/TPS-80%20Ground/Air%20Task%20Oriented%20Radar"&gt;AN/TPS-80 Ground/Air Task Oriented Radar&lt;/a&gt;.
