The US Space Force announced on Friday (April 24) that it has signed 20 contracts with 12 companies totaling up to $3.2 billion since last year for the development of Space-Based Interceptors (SBI), marking a crucial phase in President Trump’s “Golden Dome” initiative.
The “Golden Dome” defense program is expected to cost $185 billion and aims to establish a multi-layered defense system integrating ground and space sensors to counter advanced missile threats.
This project signifies a significant shift in the US missile defense strategy. Unlike existing land-based systems, the new space-based defense system will deploy interceptors in near-earth orbit. Its core technology lies in intercepting ballistic missiles during their ascent, mid-course, or glide phases, destroying them before they release multiple warheads or decoy missiles.
According to the Space Systems Command (SSC) announcement, the Space Force plans to integrate Space-Based Interceptors into the “Golden Dome” framework by 2028 and eventually deploy a dispersed SBI constellation in near-earth orbit, leveraging artificial intelligence to counter modern missile threats.
The Space Systems Command is a unit within the Space Force specifically responsible for procurement, research, and maintenance of weapon systems. Program Executive Officer (PEO) Colonel Bryon McClain emphasized the urgency of developing the “Golden Dome” system in a statement.
He stated, “The capabilities of our adversaries are rapidly advancing, and our procurement strategy must progress quicker to address the escalating speed and agility of modern missile threats.”
The list of 12 selected contractors reflects competition between traditional industry giants and emerging technology companies, including SpaceX, Lockheed Martin, Northrop Grumman, Raytheon, General Dynamics Mission Systems, Booz Allen Hamilton, Anduril Industries, True Anomaly, Turion Space, Quindar, Sci-Tec, and GITAI USA.
McClain mentioned that this diversified contracting approach aims to attract both traditional and non-traditional suppliers during the development process to maintain competitiveness, flexibility, and harness American innovation to select the best technological solutions.
While verifying the technical feasibility of the SBI system is at the core of this work, affordability is equally crucial. Major General Michael Guetlein, lead of the Golden Dome project, informed Congress during a hearing on April 15 that cost would be a determining factor in expanding the deployment of ascent-phase interception capabilities. This indicates that for contractors, ensuring both technical feasibility and cost efficiency will be a competitive race.
He said, “If conducting ascent-phase interception from space is not affordable and scalable, we will not produce it because we have other alternatives to address this issue.”
Currently, the Department of Defense has requested nearly $400 million in basic funding for the project in the 2027 fiscal year budget and proposed an additional $17 billion in related funding to be included in budget adjustment legislation to support various needs, including space defense.
