Participants including SpaceX (SPCX) and Northrop Grumman (NOC) successfully completed the first round of critical tests for the U.S. Space Force's $185 billion "Golden Dome" missile defense program on August 11, a program aimed at developing space-based missile interceptors. Analysts believe that this successful test may be more significant for SpaceX, helping it deepen its national security space business, while Northrop Grumman can integrate it into its existing mature business portfolio. However, some views also question whether SpaceX can build the system efficiently and economically.
