In December 2025, the Pentagon documented the fastest nuclear weapons expansion in Chinese history. China’s arsenal has tripled in five years to more than 600 warheads and is on track to exceed 1,000 by 2030. But a country does not triple its nuclear stockpile in five years out of prestige. China is spending billions to guarantee that a salvo aimed at American cities would get through, even after a defense system thins it on the way down.
The target of that guarantee now has a name. On Jan. 27, 2025, U.S. President Trump signed an executive order directing the construction of a missile defense shield over the United States called Golden Dome, a project the Congressional Budget Office estimates could cost as much as $542 billion for space-based components alone.

Lockheed Martin described the effort as a “Manhattan Project-scale” mission. Ronald Reagan’s Strategic Defense Initiative, better known as “Star Wars,” remains the most ambitious missile defense program ever attempted. It cost up to $100 billion before being shelved without deploying operational hardware. Golden Dome is expected to cost several times that amount. Unlike Star Wars, however, parts of the system are already being launched into orbit.

A closer look at what has already been built, what has been funded, and what remains classified suggests Beijing may have reason to be concerned.
The Iron Dome model
The strategic model behind Golden Dome is not new. Before Iron Dome, every rocket fired from Gaza created a political crisis for Israel and forced leaders to respond on the enemy’s terms. Once the defensive shield was deployed, Israel could absorb rocket barrages, intercept most of them, and decide whether, and when, to escalate.
The rockets continued to come, but the constraint they imposed on Israeli decision-making diminished. Israel gained the strategic initiative. Military operations since, from Gaza to Lebanon and the current joint campaign against Iran, have been conducted under that shield.
Meanwhile, the United States faces a similar constraint on a much larger scale. Russia, China, and North Korea all possess long-range missiles capable of delivering nuclear warheads to American cities. That capability remains the single largest factor preventing direct military confrontation.
On conventional terms, each of these states faces significant military pressure. Russia has suffered nearly 1.2 million casualties in Ukraine and lost more than 21,000 pieces of visually confirmed equipment. North Korea has sent over 10,000 troops to assist Russia’s war effort while its own military remains structured primarily for homeland defense.
China’s military leadership has also been weakened by years of internal purges, while questions remain about the real-world performance of some Chinese weapons systems. The long-range missile threat remains the one factor restraining American action. It helps explain NATO’s cautious approach in Ukraine and Washington’s continued strategic ambiguity over Taiwan. The Golden Dome is designed to weaken that constraint.
Targeting nuclear powers
Previous U.S. homeland missile defense systems were designed primarily to counter a limited number of missiles from North Korea. The Golden Dome represents a shift. Patrycja Bazylczyk, an associate fellow with the Missile Defense Project at the Center for Strategic and International Studies, has argued that the program signals a reorientation of U.S. missile defense toward Russia and China.
“The homeland missile defense architecture does not need to be impenetrable to achieve strategic effects and contribute to deterrence,” she noted.
The scale of spending reflects that ambition. Congress has already allocated more than $24 billion in the initial funding round. Meanwhile, the Missile Defense Agency opened a $151 billion umbrella contract allowing more than 2,400 companies to compete for work through 2035.
The Pentagon’s official timeline projects a demonstration under ideal conditions by late 2028. Critics argue that a full system could take a decade or more. That timeline may apply to the complete Golden Dome architecture described in the executive order. But it does not account for capabilities that are already operational.
SpaceX’s Starshield program entered a $1.8 billion classified contract with the National Reconnaissance Office in 2021 to build hundreds of satellites for continuous real-time surveillance. The first operational launches occurred in May 2024, months before the Golden Dome executive order was signed.
By early 2026, nearly 200 satellites were already in orbit. Any missile defense system depends on global launch detection and tracking. That capability is now being assembled, launch by launch, through programs that predated Golden Dome itself. When Trump signed the executive order in January 2025, he was not starting from zero. He placed a label, along with a funding structure, on an architecture that was already emerging in orbit.
Why Greenland matters
On Jan. 14, 2026, Trump stated that U.S. control of Greenland was strategically important for constructing Golden Dome. The reasoning is technical. Pituffik Space Base in northern Greenland is one of the few locations capable of communicating with satellites across multiple orbital planes used by the system’s constellation.
Greenland also contains rare earth minerals needed for thermal protection systems that allow hypersonic interceptors to survive atmospheric re-entry. In January 2026, Forbes reported that investors including Jeff Bezos, Bill Gates, and Peter Thiel had accelerated investments in Greenlandic mining ventures through companies such as KoBold Metals, betting that defense demand could override environmental barriers.
Geography also matters. Greenland sits along the great-circle flight paths that Russian and Chinese intercontinental missiles would likely follow toward North America, enabling earlier detection and longer tracking windows. Each of these elements aligns with Golden Dome’s operational requirements.
Development accelerates
On November 25, 2025, the U.S. Space Force awarded multiple contracts for space-based missile interceptor prototypes, declining to identify the recipients due to “enhanced security measures.” A second solicitation for midcourse interceptors followed in December. In traditional Pentagon procurement cycles, a single weapons solicitation can take a year simply to define requirements. Two solicitations for separate interceptor systems within two months suggests an unusually accelerated pace.
Meanwhile, a startup called Castelion, founded by former SpaceX engineers, has raised more than $450 million to mass-produce hypersonic weapons. The company has already conducted over 20 flight tests and begun constructing a 1,000-acre manufacturing campus in New Mexico.
For comparison, the Pentagon’s flagship hypersonic program spent seven years in development before completing its first full flight test in 2024. Lockheed Martin has also announced plans for its own space-based interceptor demonstration in 2028.
Beijing’s window narrows
The Pentagon’s 2025 China Military Power Report assessed that China aims to be capable of fighting, and potentially winning, a war over Taiwan by 2027. Indeed, much of China’s recent military modernization appears oriented toward that timeline: Naval expansion, amphibious capacity, missile forces, and integrated command systems. But that timeline assumes one crucial factor — that the United States remains vulnerable to nuclear retaliation.
Now, the Golden Dome could alter that calculation. The system does not need to be perfect to matter. Even a partial shield that introduces uncertainty into China’s confidence in its nuclear deterrent could widen the range of options available to American leaders during a crisis.
The Iron Dome gave Israel greater freedom to choose its battles. The public debate around Golden Dome often focuses on feasibility and cost. Yet the spending already approved, the classified contracts underway, and the hundreds of satellites already in orbit suggest the system may be advancing faster than public timelines indicate.
Now, the question may no longer be whether a shield will exist. It may be how much of it is already in place, and what strategic choices it will enable once it is.
