'''SuperDraco'''是由[[SpaceX]]設計和製造的高混合動力推進劑液體火箭發動機。它是SpaceX Draco火箭發動機家族的一部分。八台SuperDraco發動機的冗餘陣列可提供容錯推進力，用作[[龍飛船2號]]載人太空艙的[[發射逃逸系統|發射逃生系統]]。<br />
<br />
SuperDraco火箭發動機利用一種可儲存（非低溫）的推進劑，該燃料可以在加油和發射後數月內點火。它們結合了反應控制系統和主推進發動機的功能。<br />
<br />
這些發動機將用於乘機運輸到[[近地軌道]]的飛行中，還計劃用於現在已取消的[[紅龍號]]飛往[[火星]]的進入，下降和著陸控制。<br />
<br />
SuperDracos將用於[[龍飛船2號]]機組人員和貨物運輸太空艙以及{{tsl|en|SpaceX DragonFly|DragonFly}}，DragonFly是一種低空可重複使用的原型火箭，將用於推進降落技術各個方面的飛行測試。儘管該發動機能夠承受73,000牛頓（16,400磅力）的推力，但在進行DragonFly測試期間，該發動機將節流至68,170牛頓（15,325磅力），以保持載具的穩定性。<ref name=DragonFlyEAI201403>{{Citation| last1 = James| first1 = Michael| last2 = Salton| first2 = Alexandria| last3 = Downing| first3 = Micah| title = Draft Environmental Assessment for Issuing an Experimental Permit to SpaceX for Operation of the Dragon Fly Vehicle at the McGregor Test Site, Texas, May 2014 – Appendices| publisher = Blue Ridge Research and Consulting, LCC| pages = 12| date = November 12, 2013| url = https://www.faa.gov/about/office_org/headquarters_offices/ast/media/20140513_DragonFly_DraftEA_Appendices%28reduced%29.pdf| accessdate = 2020-06-05| archive-date = 2017-12-02| archive-url = https://web.archive.org/web/20171202231540/https://www.faa.gov/about/office_org/headquarters_offices/ast/media/20140513_DragonFly_DraftEA_Appendices%28reduced%29.pdf| dead-url = no}}</ref><br />
