The Trump administration is widening its supplier search for the Golden Dome, a planned $175 billion space-based missile defense shield, amid a deteriorating relationship with Elon Musk. According to a Reuters report, Pentagon and White House officials have begun courting Amazon.com’s Project Kuiper as well as launch startups Rocket Lab and Stoke Space to reduce reliance on SpaceX, whose Starlink and Starshield networks currently dominate U.S. military space communications. SpaceX remains a frontrunner because of its unrivaled launch record—more than 9,000 Starlink satellites deployed—but officials say its share of the project could shrink as individual launches are opened to competitive bidding. Established defense contractors including Lockheed Martin, Northrop Grumman and L3Harris are also in discussions to provide missile-tracking sensors and other hardware. Congress last year boosted Space Force funding for commercial satellite services to $13 billion, adding urgency to expand the vendor base. Newly confirmed Space Force Gen. Michael Guetlein has 60 days to deliver an initial system design and 120 days to present a full implementation plan, under directives from Defense Secretary Pete Hegseth.
