US Space Force awards first Golden Dome space interceptor contracts

The US Space Force has initiated its Golden Dome missile defense program by awarding the first prototype contracts for space-based boost-phase missile interceptors. These contracts, issued on November 25 through competitive Other Transaction Agreements (OTAs), mark a significant step toward developing a multi-layered homeland missile defense system that integrates space-based sensors, rapid command-and-control, and both ground and orbital interceptors. The number of companies selected and contract values were not disclosed due to security and the flexible nature of OTAs, which aim to accelerate technology development and attract non-traditional defense contractors. Golden Dome’s boost-phase interceptors are designed to destroy enemy missiles within minutes of launch, capitalizing on the missile’s bright, hot rocket plume for easier tracking. However, this approach requires rapid reaction times and a large constellation of satellites in low Earth orbit, raising concerns about feasibility. Analysts highlight challenges such as satellite “absenteeism,” where interceptors are often out of position to engage launches, with estimates suggesting nearly 950 orbit
