Incorporated with Ursa Major\u2019s Highly Loaded Grain propellant technology, the upgraded motor delivers increased performance.<\/p>\n<p>The test, conducted by Ursa Major in collaboration with BAE Systems, marks significant progress toward a flight test demonstration planned for fall 2025.<\/p>\n<p>Ursa Major claimed that its Highly Loaded Grain (HLG) technology enables longer-range missile capabilities while maintaining the original form factor. The latest upgrade delivers an enhanced range without increasing the motor\u2019s size.<\/p>\n<p>Accelerating solid rocket motor capability<\/p>\n<p>\u201cOur collaboration with BAE Systems to extend the range of the APKWS guided <a href=\"https:\/\/interestingengineering.com\/military\/us-firm-rocket-engine-component-tested\" target=\"_blank\" rel=\"dofollow noopener\">rocket<\/a> demonstrates how Ursa Major is accelerating SRM capability through innovation and speed,\u201d said Dan Jablonsky, CEO of Ursa Major.<\/p>\n<p>\u201cThese successful tests validate our approach and set the stage for a flight test this fall and our ramp to provide critical SRM production capacity.\u201d<\/p>\n<p>The extended range variant of the solid rocket motor is for the APKWS laser-guidance kit. Combat-proven for over a decade, BAE Systems\u2019 APKWS <a href=\"https:\/\/interestingengineering.com\/innovation\/the-first-hybrid-rocket\" target=\"_blank\" rel=\"dofollow noopener\">laser<\/a> guidance kit redefines precision munitions by hitting targets with pinpoint accuracy and minimal collateral damage \u2013 delivering critical lethality when it matters most.<\/p>\n<p>Flexible design architecture<\/p>\n<p>Ursa Major claims that the next-generation motor has a flexible design architecture that supports reuse of manufacturing systems across multiple missile systems and integrates with Ursa Major\u2019s Lynx Manufacturing System, a software-enabled, additive manufacturing production line that delivers scalability and speed without the bottlenecks of legacy industrial processes.<\/p>\n<p>By combining proven hardware, rapid production, and a mission-agnostic manufacturing line, Ursa Major is reshaping the solid rocket motor landscape, unlocking urgently needed capacity for the U.S. and its allies. This successful static fire comes after the announcement validating similar capabilities of both 10\u201d diameter and 5\u201d diameter SRMs, according to a <a href=\"https:\/\/www.ursamajor.com\/media\/press-release\/ursa-major-develops-extended-range-rocket-motor-for-apkws-r-laser-guidance\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">press release<\/a>.<\/p>\n<p>The motor is for the APKWS guidance kit, which transforms unguided 2.75-inch (70 millimeter) rockets like the Hydra 70 Mk 66 and others into precision-guided munitions (PGMs).<\/p>\n<p>Qualified on numerous U.S. Department of Defense (DoD) platforms, APKWS laser guidance kits provide affordable surgical-strike capability to multiple rotary-wing and fixed-wing platforms. Development, testing, and demonstrations are underway for unmanned (UAS) aircraft, as well as ground-based platforms, according to BAE Systems.<\/p>\n<p>The APKWS system bridges the gap between unguided rockets and larger anti-armor munitions with commonality across the U.S. military services \u2013 Navy, Marine Corps, Army, and Air Force. The APKWS system consistently delivers pinpoint accuracy for the highest lethality available against soft and lightly-armored targets at a lower cost than other systems.<\/p>\n<p>Ursa Major claimed that the latest test underscores the company\u2019s ability to rapidly develop, test, and deliver propulsion systems that meet urgent warfighter needs.<\/p>\n","protected":false},"excerpt":{"rendered":"A Colorado-based company has conducted successful static fires for a new extended range variant of the solid rocket&hellip;\n","protected":false},"author":2,"featured_media":78377,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[49,48,47636,47637,66,47638,306,47639],"class_list":["post-78376","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-ca","tag-canada","tag-highly-loaded-grain-propellant","tag-rocket-motor","tag-science","tag-solid-rocket-motor","tag-space","tag-ursa-major"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/78376","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=78376"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/78376\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/78377"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=78376"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=78376"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=78376"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
