The US Space Force awarded 12 companies, including SpaceX and Lockheed Martin, contracts worth up to US$3.2 billion to develop space-based missile interceptor prototypes under President Donald Trump’s Golden Dome plan, according to Bloomberg. The program aims to build a system that can destroy enemy missiles outside Earth’s atmosphere, a capability that remains unproven. Companies must demonstrate working prototypes by 2028.
The Golden Dome program represents a significant shift in US missile defense strategy, focusing on space-based interception capabilities. The contracts were issued using Other Transactional Authority, a fast-track procurement tool that accelerates development timelines compared to traditional defense contracting methods.
The Congressional Budget Office has estimated a full interceptor network could cost up to US$542 billion over 20 years, highlighting the scale of the long-term investment required for the complete system deployment.
The Pentagon faces a critical affordability challenge with the Golden Dome program. Officials worry that interceptors priced in the millions could leave US defenses at a disadvantage against cheaper enemy missiles that adversaries might use to flood the system. A Congressional Budget Office analysis reaches a similar conclusion: even if launch prices fall sharply, interceptors remain one of the biggest expenses in space-based interceptor constellations.
To address these concerns, the Space Force is using the US$3.2 billion in prototype funding as a competitive mechanism among the 12 companies. The goal is to identify designs that can be built affordably in large numbers, balancing capability with cost-effectiveness.
The Pentagon is widening the pool of companies working on space programs by adding venture-backed businesses alongside traditional defense primes. One example is True Anomaly, which received an interceptor prototype agreement under Golden Dome. The company announced a US$260 million Series C funding round, indicating strong private capital backing for space defense innovation.
The shift extends beyond missile defense. True Anomaly and Anduril, a defense technology company, were among 14 companies picked for the Space Force’s Andromeda contract vehicle. That 10-year program has a ceiling of about US$1.8 billion and covers next-generation space domain awareness capabilities, which track and identify objects in space.
Winning work in both Golden Dome and Andromeda suggests the Pentagon may be building a lasting market for a newer group of fast-moving space defense firms, marking a structural shift in how the US military sources advanced space capabilities.
