The Trump administration is actively looking for alternatives to SpaceX, which is owned by Elon Musk, for the $175 billion Golden Dome missile defence system. Previously seen as the leader in this key national security endeavour, SpaceX is currently lagging behind as the administration turns its attention to political and technical diversification.
This change of direction occurs when Elon Musk and former President Donald Trump’s relationship has rapidly deteriorated, leading to a highly publicised conflict in June 2025. To avoid relying too much on one corporation for such a vital technology, the administration is now considering other candidates, like as Jeff Bezos’s Amazon Project Kuiper, as well as more recent Internet companies and traditional defence contractors.

Fallout Between Trump and Musk Sparks Policy Shift
This strategic reorientation revolves around the disintegration of the Trump-Musk alliance. A public argument broke out on June 5, 2025, when Trump attacked Musk for rejecting a plan that would have abolished electric vehicle tax subsidies, which had a direct effect on Tesla. Trump would have lost the 2024 election without Musk’s backing, Musk said in retaliation, and he controversially connected Trump to the Epstein files. Musk also accused Trump of political hypocrisy.
Musk had previously contributed an estimated $277 million to Trump’s campaign, but his sudden turn against him and the ensuing flurry of personal insults ruined what had once been a mutually advantageous relationship between the two well-known individuals. As hostilities increased, administration representatives started to reevaluate SpaceX’s pivotal role in the Golden Dome project.

Pentagon’s Broader Concerns About Single-Point Dependency
The Pentagon and the White House were becoming increasingly alarmed about SpaceX’s hegemonic position in national defence initiatives even before the public outcry. Despite SpaceX’s impressive history, which includes the successful launch of more than 9,000 Starlink satellites, defence officials voiced concerns about relying too heavily on one privately held company for strategic purposes.
A more diverse strategy was timely justified by the Musk-Trump controversy. According to officials, the Golden Dome program—which is anticipated to be the most extensive U.S. missile defence effort ever attempted—would be more resilient, stable, and geopolitically flexible if it relied less on SpaceX.

Jeff Bezos and Project Kuiper Emerge as Key Alternatives
Jeff Bezos’s Project Kuiper, Amazon’s satellite broadband program, is one of the front-runners to fill the void left by SpaceX. Kuiper intends to launch a constellation of more than 3,000 low-Earth orbit satellites, which were first created for commercial usage but might be modified for military applications such early warning systems, worldwide communications, and missile tracking.
The administration is currently in early talks to onboard Amazon into the Golden Dome program, and Bezos has expressed a willingness to investigate defence applications for Kuiper. This is part of a larger movement to include commercial technology companies in national defence plans rather than depending just on conventional contractors like Lockheed Martin or Boeing.
Other Potential Partners: Lockheed, Northrop, and Palantir
The administration is thinking of collaborating with a variety of well-known defence companies and cutting-edge IT firms in addition to Project Kuiper. The capabilities of companies such as Northrop Grumman, Lockheed Martin, and L3Harris in the areas of interceptors, missile tracking, and space-based sensors are being assessed.
Before Musk’s fallout changed the competitive field, younger Silicon Valley companies like Palantir Technologies and Anduril Industries—both of which have strong ties to the Trump orbit—were early contenders. These companies provide real-time battlefield analytics and AI-driven defence solutions, which may be essential elements of the highly automated Golden Dome system.

Where SpaceX Still Fits In
SpaceX might still be involved, especially in the satellite and interceptor launch operations, despite the tense relationship and the administration’s expressed desire to look into other options. The business is still one of the few organisations in the world with a track record of successfully launching large payloads into space.
SpaceX has “not bid for any contracts,” according to Elon Musk, who has publicly downplayed interest in the Golden Dome. Musk also stated that the business wants to remain focused on interplanetary missions, particularly its long-term objective of colonising Mars. The administration’s efforts to find more strategically aligned and cooperative partners have only been strengthened by this ambiguity.

What Is the Golden Dome Missile Defense System?
A space-based missile shield, the Golden Dome was announced by President Trump in 2025 and is intended to defend the whole United States against a variety of threats, including ballistic, cruise, and hypersonic missiles from enemies such as North Korea, China, Iran, and Russia.
The Iron Dome in Israel serves as the model for the system, albeit it is much more ambitious and intricate. In addition to interceptor missiles in space and on the ground, it suggests deploying sophisticated sensor satellites in low-Earth orbit and possibly even directed energy weapons like lasers.

How It Would Work
The Golden Dome is designed to operate across multiple layers of missile defense:
- Orbital satellites would provide real-time detection of launches.
- AI-driven command systems would manage threat analysis and interception strategies within seconds.
- Space- and ground-based interceptors would engage threats at all three phases of flight—boost, midcourse, and terminal.
- Directed energy weapons, including experimental laser systems, may eventually be integrated to target missiles in early flight stages.
Artificial intelligence and automation would play a major role in the entire architecture, which would eliminate delays in identifying and reacting to missile threats that move quickly.

Conclusion
Despite its promise, the project is beset with significant geopolitical, financial, and technical obstacles. The Golden Dome is one of the most expensive defence projects in American history, with estimates ranging from $175 billion to more than $500 billion. International worries are also raised regarding the militarisation of space and the possibility of a new weapons race between superpowers.
Nonetheless, the Golden Dome has the potential to change how the United States handles national defence in the twenty-first century given political resolve, increased private sector participation, and escalating international conflicts.
