Trump’s “Golden Dome” Missile Defense Enters Prototyping Phase as Space Force Issues RFPs

Golden Dome Missile Defense Enters Prototyping Phase

WASHINGTON — The Trump administration’s ambitious “Golden Dome” national missile defense initiative, unveiled in May 2025, is moving into the prototyping phase as the U.S. Space Force issued a series of Requests for Proposals (RFPs) on September 18. The effort aims to build a layered shield against ballistic and cruise missile threats, blending ground-based interceptors, directed-energy weapons, and space-based tracking systems.

The move signals a rapid acceleration of the program, which Trump has described as a “21st-century Iron Dome for the American homeland.” Unlike Israel’s Iron Dome, which is designed primarily to intercept short-range rockets, Golden Dome envisions a nationwide protective network against advanced threats, including Russian and Chinese long-range missiles and potentially hypersonic glide vehicles.

Space Force Takes the Lead

The U.S. Space Force, now in its sixth year, has been tasked as the lead acquisition authority for the Golden Dome’s sensor and command-and-control architecture. Officials confirmed that RFPs were issued to major defense primes and emerging technology firms, covering areas such as:

• Next-generation interceptor design
• Directed-energy and laser integration
• Orbital sensor constellations for tracking hypersonic threats
• AI-driven battle management software

Industry sources expect Lockheed Martin, Raytheon, Northrop Grumman, and Boeing to compete aggressively for contracts, alongside newer space-focused companies.

“This will be the largest missile defense procurement initiative since the Strategic Defense Initiative of the 1980s,” said one congressional staffer, noting that Trump has championed the project as a centerpiece of his second-term defense policy.

Budget Tensions in Washington

Despite momentum, budget uncertainty looms. Congress is deeply divided on the cost of building a nationwide missile shield, with estimates ranging from $250 billion to $400 billion over the next two decades. Critics argue the system risks reviving the cost spirals of past missile defense programs, including the Bush-era Ground-based Midcourse Defense (GMD) initiative.

Democratic lawmakers have questioned whether funding Golden Dome will siphon resources from other priorities such as Pacific naval modernization and Ukraine support packages. Republicans, however, frame the program as vital to countering the growing missile arsenals of China, Russia, North Korea, and Iran.

Strategic Context

The timing of the RFP release reflects a broader shift in U.S. defense strategy. With adversaries fielding maneuverable hypersonic weapons that can bypass existing interceptors, Washington is seeking to leap ahead with a layered system that merges terrestrial and orbital capabilities.

Analysts note that the Golden Dome vision echoes aspects of Ronald Reagan’s Strategic Defense Initiative (SDI), but with technologies far closer to operational maturity. The rise of directed-energy weapons and proliferated low-Earth orbit satellites makes the project more plausible than past efforts.

Expert Analysis

Defense experts caution, however, that technological and political hurdles remain steep. “Building a continental missile defense is one thing on paper and another in practice,” said Dr. Andrew Colby, a missile defense analyst at the Hudson Institute. “Adversaries will adapt, and no shield will ever be fully impenetrable. The challenge is balancing deterrence with realistic capability.”

Still, the Space Force’s prototyping push shows Washington is prepared to invest heavily in missile defense as a pillar of U.S. homeland security in the 2030s.
