Contract Awards
The Space Force issued 20 OTA agreements to twelve firms—Anduril, Booz Allen Hamilton, General Dynamics Mission Systems, GITAI USA, Lockheed Martin, Northrop Grumman, Quindar, Raytheon (RTX), Sci-Tec, SpaceX, True Anomaly, Turion Space—with a combined ceiling of $3.2 billion. The contracts task the companies with building SBIs that can engage missiles in boost, midcourse, or glide phases, and a demonstration is planned for 2028. Oversight is provided by Col. Bryon McClain and Gen. Michael Guetlein.
Context
Golden Dome proposes a missile-defense system that adds space-based detection and kinetic interceptors to existing ground-based assets. SBIs would operate in proliferated low-Earth orbit to neutralize ballistic, hypersonic, and advanced cruise missiles shortly after launch, offering an early-engagement capability not present in current U.S. defenses.
Data
The effort includes 12 firms, 20 OTA agreements, and a $3.2 billion contract ceiling within the $185 billion Golden Dome budget. The CBO estimates a full SBI constellation could cost $542 billion over 20 years; the AEI projects $252 billion-$3.6 trillion for the same span.
Statements
Col. McClain said acquisition must accelerate as adversary missile capabilities advance rapidly. Gen. Guetlein stressed that affordability will decide whether SBIs proceed to production, noting the program will not move forward without cost-effectiveness. A Space Force release highlighted AI-driven tracking and interceptors to address speed and maneuverability.
Cost Concerns
Analysts warn a full SBI fleet could far exceed the $185 billion Golden Dome budget, raising economic viability concerns. The CBO’s $542 billion estimate and AEI’s $252 billion-$3.6 trillion range suggest the system may be unaffordable at scale, risking exclusion from the final architecture. Contracts also omit individual award values and the planned interceptor count, leaving the program’s ultimate scale uncertain.
Quotes
- “Adversary capabilities are advancing rapidly, and our acquisition strategies must move even faster to counter the growing speed and maneuverability of modern missile threats.” — Col. Bryon McClain, Program Executive Officer, Space Combat Power
- “We are so focused on affordability. If we cannot do it affordably, we will not go into production.” — Gen. Michael Guetlein, Director, Office of Golden Dome for America
- “If boost-phase intercept from space is not affordable and scalable, we will not produce it because we have other options to get after it.” — Gen. Michael Guetlein, House Armed Services Strategic Forces Subcommittee testimony
- “Proven and formidable U.S. missile defense systems, combined with next-generation space-based tracking and advanced interceptors must be integrated with Artificial Intelligence to counter the speed, maneuverability, and lethality of the threats.” — Space Force press release
Next Steps
The contractors must deliver functional SBI prototypes by 2028. After the demonstration, the Space Force will assess performance and cost data to decide whether to move SBIs into production, shaping the final Golden Dome architecture.
