On May 20, 2025, President Donald Trump unveiled the “Golden Dome,” an ambitious missile defense initiative to shield the United States from a spectrum of missile threats, including ballistic, hypersonic, and space-launched projectiles. Drawing inspiration from Israel’s Iron Dome and Ronald Reagan’s Strategic Defense Initiative, this project signifies a significant escalation in U.S. defense strategy, emphasizing space-based technologies.
The Golden Dome is envisioned as a multi-layered defense system, integrating a vast network of space-based sensors and interceptors designed to detect and neutralize missile threats at various stages of their trajectory. General Michael Guetlein of the U.S. Space Force has been appointed to lead this initiative, with an initial budget allocation of $25 billion and projected costs potentially reaching $175 billion.
This system aims to deploy hundreds of satellites for missile detection, tracking, and interception with companies like SpaceX, Lockheed Martin, and Palantir Technologies. The companies express interest in contributing to the project.

Despite this enthusiasm, the project faces significant challenges. Experts warn that the technical feasibility of deploying a comprehensive space-based missile defense system is questionable. This cites the need for thousands of interceptors in orbit to ensure adequate coverage. A study by the American Physical Society estimated that approximately 16,000 space-based interceptors would be required to defend against a salvo launch of North Korea’s Hwasong-18 missiles.
The history of the Golden Dome can be explored by knowing the concept of a space-based missile defense system. This system is not new. In the 11980s, President Ronald Reagan proposed the Strategic Defense Initiative (SDI), colloquially known as “Star Wars,” aiming to develop a space-based system to protect the U.S. from nuclear attacks. The SDI faced technological and financial hurdles, leading to its eventual cancellation in the 1990s. Similarly, the Golden Dome faces skepticism regarding its feasibility and cost-effectiveness.
Critics argue that the deployment of such a system could disrupt the strategic balance, prompting adversaries like China and Russia to expand their missile arsenals, potentially sparking a new arms race.The weaponization of space raisies legal and geopolitical concerns as it may violate international treaties like the 1967 Outer Space treaty.
The Golden Dome is projected to become operational by 2029, which aligns with the end of Trump’s second term. However, experts question the feasibility of this timeline, citing the immense technical, financial, and organizational challenges involved. The project’s success will depend on overcoming these hurdles and securing sustained political and public support.
The Golden Done could enhance the U.S.’s missiles defense capabilities, potentially deterring adversaries and protecting against emerging threats. However, the high costs and potential for escalating global tensions may outweigh the benefits. When the project progresses, considering its implications on national security and strategic stability will be crucial.
