And it stands up against enemy drones, along with artillery and other small, fast threats.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The advanced, adaptable, multi-mission radar made by Raytheon Missiles &amp; Defense, a Raytheon Technologies business, is the U.S. Army\u2019s \u2018go-to\u2019 sensor to find all classes of unmanned aircraft systems, or UAS, commonly called drones.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cKuRFS is tailor-made for the counter-UAS mission, and no other radar in the world does this mission as effectively,\u201d said Will Strauss, technology director for short- and medium-range ground-based air defense programs at Raytheon Missiles &amp; Defense.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Developed in partnership with the Army, the radar was originally built to help defeat rocket, artillery and mortar, or RAM, attacks in the Afghanistan and Iraq wars. It was fielded in 2013 for a new mission \u2013 short-range air defense, or SHORAD, and it has surpassed 1.6 million operational hours.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Today, the Army operates nearly 60 KuRFS radars around the world, providing persistent 360-degree surveillance \u2013 detecting, tracking and discriminating airborne objects. Though it\u2019s specifically used for SHORAD missions , KuRFS can see helicopters and planes up to and beyond 100 kilometers (62 miles).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once KuRFS finds threats, it warns and cues defensive weapons to intercept them using kinetic effectors and non-kinetic engagement such as directed energy. Its ability to detect threats from long distances gives soldiers stand-off distance for safety and ample time to make an engagement decision.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And it keeps getting better. KuRFS continues to evolve to stay ahead of threats. Raytheon Missiles &amp; Defense works closely with the Army to update and sustain the system for reliable performance and readiness in all environments where they operate.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1600\" height=\"776\" src=\"\/wp-content\/uploads\/2026\/08\/4527224_RMD_vehicle_photoedit_v2.jpg.jpg\" alt=\"\" class=\"wp-image-117257\" srcset=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4527224_RMD_vehicle_photoedit_v2.jpg.jpg 1600w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4527224_RMD_vehicle_photoedit_v2.jpg.jpg?resize=300,146 300w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4527224_RMD_vehicle_photoedit_v2.jpg.jpg?resize=768,372 768w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4527224_RMD_vehicle_photoedit_v2.jpg.jpg?resize=1024,497 1024w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4527224_RMD_vehicle_photoedit_v2.jpg.jpg?resize=1536,745 1536w\" sizes=\"auto, (max-width: 1600px) 100vw, 1600px\" \/><figcaption class=\"wp-element-caption\">The Ku-720 mobile sensing radar and Coyote effectors were used to detect and defeat enemy drones in a 2022 test at the U.S. Army Yuma Proving Ground in Arizona.<\/figcaption><\/figure>\n\n\n\n<h6 class=\"wp-block-heading\"><b>Evolves with threats<\/b><\/h6>\n\n\n\n<p class=\"wp-block-paragraph\">Adversarial drones are a proliferating threat \u2013 a relatively low-cost tool for conducting intelligence, surveillance, reconnaissance and attack missions against critical assets and forces around the globe. Because they are readily available, these hostile vehicles\u2019 capabilities and tactics are quickly evolving.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAdversaries are spending less time making their drones resistant to attack,\u201d Strauss said. \u201cThey\u2019re more focused on creating a wide variety of low-cost drones \u2013 from very small and slow UASs to larger and slightly faster ones. But KuRFS can detect all of them.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In fact, it\u2019s specifically designed for a changing threat environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cFrom the ground up, KuRFS is an agile and scalable digital sensor, continually able to adapt to the evolving and most challenging SHORAD threats,\u201d said Don Williams, Requirements and Capabilities director for SHORAD programs at RMD.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While KuRFS started out as a sense-and-warn radar, its precision targeting capabilities and reliable performance have made it highly effective for expanded missions, such as air surveillance, counter-RAM and now, counter-UAS.<\/p>\n\n\n\n<h6 class=\"wp-block-heading\"><b>Sees through clutter<\/b><\/h6>\n\n\n\n<p class=\"wp-block-paragraph\">KuRFS uses active electronically scanned array, or AESA, technology that enables exact steering of its beam toward a threat. The radar owes its precise sensing and fire control to its operation on the Ku-band of the electromagnetic spectrum.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Ku band\u2019s short wavelengths produce significantly sharper image resolution than other parts of the electromagnetic spectrum, and it enables the KuRFS radar to tell the difference between many small objects at once. It can even see and identify an incoming 9 mm bullet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That makes it optimal for picking small UAS out of a group of objects or clutter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe wave doesn\u2019t get lost or degrade the farther out it searches,\u201d Williams said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The KuRFS radar is not large, but it\u2019s big on benefits. Mounted on a pallet, the system is almost four feet in diameter. On a vehicle, it\u2019s about three feet. And, in a distributed configuration, each aperture mounted on the four corners of a vehicle are about 20 inches square.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cKuRFS bolsters a layered defense by ensuring efficient and low-cost SHORAD operations. Warfighters can take it wherever they go, with confidence that the radar is up to the mission,\u201d Williams said. \u201cEven as adversaries adapt from a single-threat environment to multiples to highly integrated swarms of drones, KuRFS meets that challenge.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1600\" height=\"780\" src=\"\/wp-content\/uploads\/2026\/08\/4527224_RMD_Sensor_photoedit_v1.jpg.jpg\" alt=\"\" class=\"wp-image-117258\" srcset=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4527224_RMD_Sensor_photoedit_v1.jpg.jpg 1600w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4527224_RMD_Sensor_photoedit_v1.jpg.jpg?resize=300,146 300w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4527224_RMD_Sensor_photoedit_v1.jpg.jpg?resize=768,374 768w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4527224_RMD_Sensor_photoedit_v1.jpg.jpg?resize=1024,499 1024w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4527224_RMD_Sensor_photoedit_v1.jpg.jpg?resize=1536,749 1536w\" sizes=\"auto, (max-width: 1600px) 100vw, 1600px\" \/><figcaption class=\"wp-element-caption\">In a fixed or mobile configuration, KuRFS has proven effective in detecting, tracking and identifying in-coming threats, including objects as small as a 9mm bullet.<\/figcaption><\/figure>\n\n\n\n<h6 class=\"wp-block-heading\"><b>Meets many missions<\/b><\/h6>\n\n\n\n<p class=\"wp-block-paragraph\">KuRFS is integrated with more than 15 weapon systems, including Raytheon Missile &amp; Defense\u2019s land-based Phalanx weapon system, <a href=\"https:\/\/www.raytheonmissilesanddefense.com\/what-we-do\/counter-uas\/effectors\/coyote\">Coyote<\/a> family of effectors and <a href=\"https:\/\/www.raytheonmissilesanddefense.com\/what-we-do\/counter-uas\/effectors\/phaser-high-power-microwave\">Phaser<\/a> high-power microwave, as well as <a href=\"https:\/\/www.raytheonintelligenceandspace.com\/what-we-do\/advanced-tech\/lasers\">HELWS<\/a>, a high-energy laser weapon system made by Raytheon Intelligence &amp; Space, also a Raytheon Technologies business. KuRFS is integrated with the Forward Area Air Defense Command and Control system for the Army\u2019s SHORAD system. And the radar also provides the cueing data for 50-caliber guns and 30mm cannons.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For counter-UAS engagements, KuRFS gives the Coyote effector superior sensing capability against a broad set of UAS threats over a long range, detecting even the smallest class of drones out beyond 15 kilometers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIt provides the operator of any system it\u2019s integrated with flexibility and a clear, accurate vision for quick decision-making to defeat a threat target,\u201d Strauss said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">KuRFS can also be deployed to stand sentry by itself in a \u201csense-and-warn\u201d mission, \u201cso that if a base is under attack, the radar gives troops enough time to seek cover,\u201d Strauss said.<\/p>\n\n\n\n<h6 class=\"wp-block-heading\"><b>Weaves a digital thread<\/b><\/h6>\n\n\n\n<p class=\"wp-block-paragraph\">Digital technologies, such as artificial intelligence and machine learning, play a key role in KuRFS\u2019 capacity to outpace current and future threats. Engineers use digital engineering in every stage of the sensor\u2019s lifecycle, from design to production to sustainment. It not only supports the rapid deployment of new capabilities, like software upgrades, but also helps inform performance assessments through modeling and simulation as well as verification that systems meet customer requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe\u2019ve always used cutting-edge design techniques for AESA radars, and our digital modeling of each system covers almost all the disciplines \u2013 from mechanical, thermal, stress, electrical and RF to sustainment and human factors,\u201d Strauss said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Digital engineering allows Raytheon Missiles &amp; Defense to collaborate with the Army in real time, moving faster to bring together better ideas, designs and capability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cTogether, we\u2019re continuing the evolution of KuRFS, updating it and adding new capabilities to enhance its performance, increase reliability and cut costs. All this helps keep us ahead of advanced adversarial techniques,\u201d Strauss said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.raytheonmissilesanddefense.com\/what-we-do\/counter-uas\/sensors\/kurfs\">Learn more about KuRFS<\/a>.<\/p>\n","protected":false},"author":7,"featured_media":117255,"menu_order":0,"template":"single-native-legacy","meta":{"_acf_changed":false,"_acf":"","_yoast_wpseo_primary_category":"15"},"advertiser":[3629],"class_list":["post-63644","native","type-native","status-publish","has-post-thumbnail","hentry","advertiser-raytheon-missiles-defense"],"acf":{"subheadline":"","legacy_arc_id":"6BGYR4TBKFDPHDCCJWUQ7MIEQM","arc_canonical_url":"\/native\/raytheon-missiles-defense\/2022\/11\/22\/birds-planes-drones-kurfs-radar-can-spot-them-all\/","remove_feature_photo":false,"is_sponsored":false,"subtype":"native-layout","redirect_url":"","disable_inline_ads":false,"native_logo_pretext":"Presented By:"},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v26.0 (Yoast SEO v28.1) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Birds, Planes, Drones \u2013 KuRFS Radar Can Spot Them All - Defense News<\/title>\n<meta name=\"description\" content=\"KuRFS: It stands for Ku-band Radio Frequency System.
