Trump’s ‘Golden Dome’ Missile Defense Shield Sparks Controversy: A New Space Race?

President Donald Trump's ambitious "Golden Dome" missile defense shield project is generating both excitement and controversy. The plan, intended to protect the U.S. from missile threats, is facing scrutiny regarding its feasibility, cost, and potential impact on international relations. Is this a necessary step for national security, or a dangerous escalation of a space arms race?

The president unveiled a plan to spend $25 billion to begin work on the Golden Dome missile defense system on Tuesday, insisting it would take only three years to complete

The Golden Dome project, announced with an initial $25 billion investment, aims to create a multi-layered defense system capable of intercepting missiles launched from anywhere, even space. This includes sensors to detect incoming threats, ground-based interceptor missiles, and systems to counter lower-altitude threats like hypersonic missiles and drones.

SpaceX, along with partners Palantir and Anduril, is a frontrunner to win a significant part of the project, specifically the "custody layer." This involves a constellation of satellites to detect and track missiles, determining if they are heading towards the U.S. SpaceX estimates this part alone could cost between $6 billion and $10 billion, leveraging their experience with hundreds of operational spy satellites.

However, the project faces significant skepticism. The Congressional Budget Office estimates a much longer timeline and a far greater cost ($524 billion and 20 years) than Trump's projections. Senator Angus King has questioned the ability to defend against a substantial missile attack from Russia or China.

U.S. President Donald Trump makes an announcement regarding the Golden Dome missile defense shield next to U.S. Defense Secretary Pete Hegseth in the Oval Office of the White House in Washington, D.C., U.S., May 20, 2025.

Internationally, the Golden Dome is causing friction. China has accused the U.S. of "turning space into a warzone," arguing that the project violates the principle of peaceful use of outer space and risks a space arms race. Chinese Foreign Minister Mao Ning stated the project has a strong offensive nature and urged the U.S. to abandon its development. In response, China affirms that they are gravely concerned about this project.

Russia has indicated that the project could prompt discussions on strategic arms control between the two countries, particularly given the U.S.'s withdrawal from key treaties in recent years.

The Golden Dome project raises fundamental questions about the future of space exploration and international security. Will it truly enhance U.S. security, or will it trigger a costly and destabilizing arms race in space? The outcome remains uncertain, but the debate surrounding the Golden Dome is sure to continue.
