(Worthy News) – President Trump’s proposed Golden Dome missile shield could cost as much as $1.2 trillion over 20 years, according to a new Congressional Budget Office study that offers one of the most detailed public estimates yet of the ambitious national missile-defense project.
The report, requested by Sen. Jeff Merkley, D-Ore., said the proposed system would represent the most advanced and far-reaching missile-defense network ever built by the United States. But even at that scale, the CBO warned it would not create an “impenetrable shield” capable of fully stopping a major missile attack from nuclear powers such as Russia or China.
“Although the notional NMD system analyzed by CBO would be far more capable than defenses the United States fields today, it would not be an impenetrable shield,” the report said.
Trump has promoted Golden Dome as a landmark investment in homeland defense, arguing that America must respond to rapidly expanding ballistic and hypersonic missile programs in Russia, China and other hostile nations. At a 2025 White House event, Trump said the system would be capable of intercepting missiles launched “from the other side of the world” and even from space.
“Once fully constructed, the Golden Dome will be capable of intercepting missiles even if they’re launched from the other side of the world and even if they are launched from space,” Trump said. “And we will have the best system ever built.”
The CBO study assumed a four-layer defense architecture: one layer in space, two wide-area ground-based layers, and smaller regional layers designed to protect critical cities, military bases and infrastructure. Ground systems would likely rely in part on existing capabilities such as THAAD batteries, while the space-based layer would require major new development.
The largest cost driver is the proposed space-based interceptor network. The CBO estimated that a constellation of 7,800 satellites capable of engaging at least 10 simultaneous intercontinental ballistic missiles would cost $723 billion to acquire and deploy. Because each satellite would have an estimated five-year service life, at least 1,600 new interceptors would need to be launched every year to maintain the system.
By contrast, ground- or sea-based defenses would cost an estimated $139 billion.
The CBO said acquisition costs alone would total just over $1 trillion, with the remaining costs tied to operations, support, command-and-control systems, missile-tracking networks, radars, counterdrone protection and other infrastructure.
The price tag is far above earlier White House estimates. The Trump administration initially projected the program could cost $175 billion over three years, while Gen. Michael A. Guetlein, the U.S. Space Force vice chief of space operations and the administration’s lead official for Golden Dome, recently placed the estimate at $185 billion.
So far, roughly $23 billion has been allocated, while the White House’s fiscal 2027 budget request includes another $17.1 billion, bringing total projected funding to about $40 billion.
Merkley blasted the proposal as wasteful, calling it “a massive giveaway to defense contractors paid for entirely by working Americans.” But the Trump administration and national security officials argue the project is necessary in an era when America’s adversaries are investing heavily in next-generation weapons.
Retired Air Force Gen. John E. Hyten, former vice chairman of the Joint Chiefs of Staff and commander of U.S. Strategic Command, warned that bureaucracy could become the project’s greatest obstacle.
“Will we get there in three years? Not with the current bureaucracy,” Hyten told The Washington Times. “If they don’t let him, you’ll not get there in three years. We won’t get there in six years, we won’t get there in 10 years.”
For Trump, Golden Dome is a bold peace-through-strength initiative aimed at ensuring America is never left vulnerable to a devastating missile attack. For critics, it is a budgetary giant with uncertain limits.
