La construction devrait d\u00e9buter d\u00e8s 2027, avec un premier lancement attendu en 2029. \u00c0 terme, le site devrait permettre de r\u00e9aliser des milliers de vols Starship par an.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Le spatioport devrait compter 10 sites de lancement de fus\u00e9es, r\u00e9partis en paires s\u00e9par\u00e9es d\u2019environ 2,5 kilom\u00e8tres chacune, selon une estimation d&rsquo;Interstellar Gateway.<\/li>\n\n\n\n<li>\u00ab&#160;Starbase Louisiana&#160;\u00bb devrait \u00e9galement comporter des fermes de propergol, des bassins de

propergol.<\/li>\n\n\n\n<li>Un centre de fabrication des fus\u00e9es Starship ainsi qu\u2019un hangar d\u2019assemblage et de stockage pourraient \u00e9galement \u00eatre construits sur le

\u00ab&#160;Starbase Louisiana&#160;\u00bb resterait bien plus modeste que plusieurs grands spatioports, comme le site de Ba\u00efkonour, au Kazakhstan, utilis\u00e9 par la Russie, le Centre spatial guyanais utilis\u00e9 pour les programmes spatiaux fran\u00e7ais et europ\u00e9en, ou le Centre spatial Kennedy, en Floride.<\/li>\n\n\n\n<li>Le site pourrait toutefois permettre une cadence de lancement bien sup\u00e9rieure \u00e0 ce qui est observ\u00e9 aujourd\u2019hui&#160;: jusqu\u2019\u00e0 plus de 30 vols par jour, selon Elon Musk, contre environ un tous les deux jours en moyenne
