This marks a significant escalation from the current 50 launches per year at SLC-4E, positioning Vandenberg as a cornerstone for medium- and heavy-lift missions to polar and other orbits.<\/p>\n<p>The ROD selects Alternative 1, which fully endorses SpaceX\u2019s proposed actions, including the construction of a new integration hangar adjacent to SLC-6 for Falcon 9 and Falcon Heavy processing. Unlike earlier plans to modify existing facilities, this fresh build\u2014located south of the horizontal integration area\u2014will streamline operations without disrupting current capabilities.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" aria-describedby=\"caption-attachment-109949\" class=\"size-full wp-image-109949\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2025\/10\/NSF-2025-10-19-22-15-00-253.jpg\" alt=\"\" width=\"1667\" height=\"983\" srcset=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2025\/10\/NSF-2025-10-19-22-15-00-253.jpg 1667w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2025\/10\/NSF-2025-10-19-22-15-00-253-350x206.jpg 350w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2025\/10\/NSF-2025-10-19-22-15-00-253-594x350.jpg 594w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2025\/10\/NSF-2025-10-19-22-15-00-253-768x453.jpg 768w, https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2025\/10\/NSF-2025-10-19-22-15-00-253-1170x690.jpg 1170w\" sizes=\"(max-width: 1667px) 100vw, 1667px\"><\/p>\n<p id=\"caption-attachment-109949\" class=\"wp-caption-text\">A slide from the Environmental Impact Statement.<\/p>\n<p>SpaceX will now undertake a similar approach to that being conducted at another former United Launch Alliance site at the Cape, with SLC-37 being converted to host Starship launches.<\/p>\n<p>The expansion also encompasses increased rocket landings at this and downrange sites in the Pacific Ocean, alongside Federal Aviation Administration (FAA) licensing for airspace closures during launches.
