This week, the Army was granted a patent for a net-carrying grenade-sized weapon, designed to work in a standard 40mm launcher, that can ensnare a drone. Formally a \u201cscalable effects net warhead,\u201d the net grenade could finally provide a countermeasure to cheap drones that\u2019s almost as inexpensive as the drones themselves.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ensnaring a robot in a net is perhaps the opposite of lethality, but here that\u2019s a selling point \u2014 stopping the drone means immediately disabling it and possibly doing a forensic investigation on the drone\u2019s innards afterwards. Bullets can stop drones, but it\u2019s a hard task even at <a href=\"https:\/\/www.popsci.com\/article\/technology\/how-hard-it-shoot-down-small-drone-video-0\" target=_blank>sport shooting competitions<\/a> and in a real-life application bullets still have to fall somewhere, risking injury to friendly forces and bystanders. Anti-air missiles like the Patriot can also<a href=\"https:\/\/www.bbc.com\/news\/technology-39277940\" target=_blank> intercept drones<\/a>, but drones can be as cheap as a few hundred dollars and missiles like the Patriot can cost a few million dollars. Both more-kinetic options can ruin the drone\u2019s circuitry, obliterating any useful clues as to who may have launched the drone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nets also hold an advantage over directional jammers in that they only have to hit the drone once to work. Directional jammers, while often <a href=\"https:\/\/www.c4isrnet.com\/unmanned\/2018\/07\/20\/watch-oklahoma-national-guard-train-with-counter-drone-equipment-in-afghanistan\/\" target=_blank>portable and rifle-sized<\/a>, have to stay focused on the target drone until the drone is brought down, or else risk the drone being able to receive signals from its remote pilot and detonate or fly away.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nets are so popular a counterdrone tool that we\u2019ve seen existing <a href=\"https:\/\/www.popsci.com\/drone-protection-company-brought-net-guns-boston-marathon\" target=_blank>net-guns<\/a> used to stop wildlife re-purposed to catch UAVs, drones <a href=\"https:\/\/www.popsci.com\/watch-japans-police-drone-catch-quadcopter\" target=_blank>carrying nets<\/a>, drones <a href=\"https:\/\/www.popsci.com\/drone-catcher-drone-fires-nets-at-lesser-drones\" target=_blank>carrying net-guns<\/a>, and custom dedicated net-launching <a href=\"https:\/\/www.popsci.com\/skywall-is-an-anti-drone-net-bazooka\" target=_blank>bazooka-like weapons<\/a>. All of these require dedicated training of varying degrees, especially in the case of piloting drones as counterdrone weapons. A net-containing package that fits into a launcher already familiar to <a href=\"https:\/\/www.army-technology.com\/news\/industry-news\/us-army-grenade-net-drones\/\" target=_blank>soldiers<\/a> could provide a simpler, easier to adopt way to shoot down drones.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This counterdrone net grenade would open when sensors indicate it is close to a target, and then the net inside the grenade would be launched onto the drone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe results of initial testing show that the warhead of this invention can be launched (currently in a 40 mm configuration) and can successfully engage a UAS threat,\u201d reads the <a href=\"http:\/\/patft.uspto.gov\/netacgi\/nph-Parser?Sect1=PTO2&#038;Sect2=HITOFF&#038;p=1&#038;u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&#038;r=1&#038;f=G&#038;l=50&#038;co1=AND&#038;d=PTXT&#038;s1=Blyskal&#038;OS=Blyskal&#038;RS=Blyskal\" target=_blank>patent<\/a>. \u201cThe performance of this invention goes further than any previous system proposed which merely launches a net directly at a UAS.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to stopping drones, the patent bills the launched nets as useful against boats, boat propellers, moving land vehicles and stationary land vehicles. If a net could conceivably stop it, then a grenade-launched net is a way to make that happen faster.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With cheap drones comes a great opportunity for countering cheap drones. On the battlefield of the future, the answer to drones may just be net-slingers.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The service has patented net-containing grenades, fired from standard 40mm launchers, as an easily adopted answer to a host of vehicular threats.<\/p>\n","protected":false},"author":7,"featured_media":62098,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_yoast_wpseo_meta-robots-noindex":"","_yoast_wpseo_meta-robots-nofollow":"","_yoast_wpseo_canonical":"","_acf":"","_yoast_wpseo_primary_category":21,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","_smg_distribution_targets":[]},"categories":[106,29,32,21,111],"tags":[],"coauthors":[3021],"class_list":["post-20473","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-daily-brief","category-home","category-newsletters","category-unmanned","category-unmanned-systems"],"acf":{"subheadline":"","legacy_arc_id":"SWRBLZ5K5NDODOTD6GPZF7WJFU","arc_canonical_url":"\/unmanned\/2019\/02\/11\/army-patents-net-containing-grenade-to-stop-drones\/","remove_feature_photo":false,"is_sponsored":false,"subtype":"","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>The Army is testing net grenades to stop drones - C4ISRNet<\/title>\n<meta name=\"description\" content=\"The service has patented net-containing grenades, fired from standard 40mm launchers, as an easily adopted answer to a host of vehicular threats.\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/one.sightlinemg.com\/c4isrnet\/unmanned\/2019\/02\/11\/army-patents-net-containing-grenade-to-stop-drones\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"The Army is testing net grenades to stop drones\" \/>\n<meta property=\"og:description\" content=\"The service has patented net-containing grenades, fired from standard 40mm launchers, as an easily adopted answer to a host of vehicular threats.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/one.sightlinemg.com\/c4isrnet\/unmanned\/2019\/02\/11\/army-patents-net-containing-grenade-to-stop-drones\/\" \/>\n<meta property=\"og:site_name\" content=\"C4ISRNet\" \/>\n<meta property=\"article:published_time\" content=\"2019-02-11T19:56:35+00:00\" \/>\n<meta property=\"article:modified_time\" content=\"2026-08-08T18:07:21+00:00\" \/>\n<meta name=\"author\" content=\"Kelsey D.
