NASA transferred the project to the U.S. military in 2004, specifically, the Defense Advanced Research Projects Agency (DARPA). At that point, X-37 became a classified project.<\/p>\n\n\n\n<p>Unlike a conventional space shuttle, the X-37B is an unmanned robotic aircraft that is managed by the U.S. Force\u2019s Rapid Capabilities Office in collaboration with the Space Force. The spacecraft has been designed and developed by Boeing and the National Aeronautics and Space Administration (NASA).<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-large is-resized\"><a href=\"https:\/\/i0.wp.com\/www.ir-ia.com\/news\/wp-content\/uploads\/2023\/12\/USAF-Boeing-X-37B.jpg?ssl=1\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"1016\" height=\"678\" src=\"https:\/\/i0.wp.com\/www.ir-ia.com\/news\/wp-content\/uploads\/2023\/12\/USAF-Boeing-X-37B.jpg?resize=1016%2C678&#038;ssl=1\" alt=\"X-37B space plane\" class=\"wp-image-20450\" style=\"width:841px;height:auto\" srcset=\"https:\/\/i0.wp.com\/www.ir-ia.com\/news\/wp-content\/uploads\/2023\/12\/USAF-Boeing-X-37B.jpg?resize=1024%2C683&amp;ssl=1 1024w, https:\/\/i0.wp.com\/www.ir-ia.com\/news\/wp-content\/uploads\/2023\/12\/USAF-Boeing-X-37B.jpg?resize=300%2C200&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.ir-ia.com\/news\/wp-content\/uploads\/2023\/12\/USAF-Boeing-X-37B.jpg?resize=768%2C512&amp;ssl=1 768w, https:\/\/i0.wp.com\/www.ir-ia.com\/news\/wp-content\/uploads\/2023\/12\/USAF-Boeing-X-37B.jpg?resize=589%2C392&amp;ssl=1 589w, https:\/\/i0.wp.com\/www.ir-ia.com\/news\/wp-content\/uploads\/2023\/12\/USAF-Boeing-X-37B.jpg?w=1200&amp;ssl=1 1200w\" sizes=\"auto, (max-width: 1016px) 100vw, 1016px\" \/><\/a><figcaption class=\"wp-element-caption\"><em><sup>X-37B 1 sits on the runway after landing at the Shuttle Landing Facility on 12 November 2022, the 909th day of the OTV-6 (USA-299) mission.
