Golden Dome missile defense faces claims of trillion-dollar costs and strategic instability, but the focused architecture costs $185 billion through the mid-2030s and reaches initial operating capability by 2028 while complementing nuclear deterrence.
The emergence of Golden Dome as a homeland defense architecture marks a major shift in how Washington thinks about deterrence. For decades, nuclear retaliation alone was seen as enough to protect the continental United States from foreign attack. That assumption no longer holds. Adversaries now field conventional ballistic, hypersonic, and cruise missiles capable of striking critical infrastructure without crossing the nuclear threshold. Golden Dome is designed to close this vulnerability by creating layered sensors and interceptors across land, sea, air, and space. Its purpose is not to replace nuclear deterrence but to deny the first-wave conventional attack that could disrupt command systems and delay military mobilization.
Critics argue the program is unaffordable and strategically destabilizing, yet current cost estimates point to a focused architecture of $185 billion through the mid-2030s, far below the trillion-dollar figures in recent reporting. Golden Dome also answers a deeper problem: American vulnerability to non-nuclear strikes now invites coercion. By raising the cost and uncertainty of any attack, the system aims to restore stability. The debate is no longer whether homeland missile defense is desirable, but whether Congress will fund it predictably enough to deliver initial capability by 2028.
Why Golden Dome Now?
Recent reporting last week suggests that the Golden Dome missile defense system will cost more than $1 trillion and that its utility is questionable. Both positions are inaccurate. Recent cost estimates do not reflect the actual planned architecture of Golden Dome’s program office. The argument that Golden Dome will compromise nuclear deterrence and thereby erode strategic stability does not fully appreciate the extraordinary new threats to the homeland that have been created not just by drones—but even more importantly—by ballistic, hypersonic, and cruise missile systems capable of carrying non-nuclear payloads to critical infrastructure and targets in the United States.
Strategic stability is eroding. The risk of deterrence failure is growing daily. Two oceans and friendly nations to the north and south no longer provide what was once considered a North American sanctuary. Our country faces daily attacks in the cyber domain and information space, often aimed at fanning the flames of internal discord. While drones are receiving much of the attention today, China, Russia, and others, such as North Korea, have relentlessly fielded, as well, highly capable ballistic, hypersonic, and cruise missiles. They can carry both conventional and nuclear payloads.
New Missile Threats Erase Old Assumptions
These weapons can be delivered from space, air, land, sea, and sub-sea. They can hold the North American homeland at risk, along with those of European and Asian allies. Even rogue actors such as the Houthis are fielding capable conventional missiles thanks to Iran. For decades, Washington almost exclusively relied on nuclear retaliation to deter Moscow and Beijing. For North Korean and Iranian threats, US policy was content to provide for only more limited missile defense.
Today, the United States faces what has become a strategic missile gap. An array of modern, offensive conventional systems, both kinetic and non-kinetic, are now more than capable—without using nuclear weapons—of disrupting Washington’s national command response system and gravely damaging critical US infrastructure. To deter such attacks on the homeland, the United States must field Golden Dome for America—a layered, integrated air and missile defense architecture designed to counter these new conventional threats.
Can Nuclear Retaliation Alone Deter?
The nuclear deterrent remains necessary as the foundation of homeland defense. Today, however, the US military’s strategic options are over-tilted toward deterrence by massive nuclear retaliation. Golden Dome will complement the US nuclear deterrent by strengthening deterrence against first-wave conventional attacks by defense denial. Deterrence works when an adversary concludes that an attack will fail to achieve its objectives or that the cost will far outweigh any gain. Golden Dome defensive systems, along with a comprehensive homeland defense campaign plan, will address that decisively. It will create a multi-layered shield—sensors and effectors, both kinetic and non-kinetic, operating from the ground, sea, air, and space.
Golden Dome Strengthens Defense Denial
An adversary contemplating any kind of conventional (or limited nuclear) attack against the United States will have to take account of the real possibility that many of its attacking weapons will be neutralized by a combination of Golden Dome kinetic and non-kinetic shields. The uncertainties and complexities created by Golden Dome will complicate foes’ planning, reducing the potential value of any missile or drone threat. Golden Dome will not replace nuclear deterrence. Instead, it will fill a dangerous strategic gap created by a new age of conventional weapons systems.
Some claim that Golden Dome will undermine strategic stability by threatening an adversary’s second-strike nuclear capability, thus fueling an arms race. This could not be further from the truth. Aggression is much more likely when one actor is unable, or perceived to be less capable, of defending itself against a range of threats, such as conventional missile or cyber-attack. Arguably, this is where the United States is headed today. Golden Dome is not designed to make nuclear weapons obsolete or to enable a US first strike with impunity. Even a highly effective first strike architecture would leave residual risk that no rational US president would accept as a basis for aggression.
Adversary Doubt Creates Strategic Stability
What Golden Dome provides is a deterrent for the more plausible scenarios of the coming decades: limited conventional strikes aimed at intimidating Washington at a moment of crisis; disrupting strategic infrastructure; and impeding the ability of US forces to be sent from the homeland to support allies. Golden Dome will dramatically raise the cost of such adventurism. It will provide Washington more tools to preserve peace under pressure. Today’s vulnerability against conventional-style attacks is creating instability—handing our foes an open invitation to attack the homeland using non-nuclear tools.
Funding Uncertainty Could Kill the Program
Golden Dome is affordable and achievable. The current cost estimate for a focused architecture is $185 billion through the mid-2030s. The approach prioritizes affordability and scalability. Golden Dome will be fielded in a phased deployment, beginning with expanded terrestrial and maritime capabilities. It will eventually progress to space-based sensors and interceptors. Initial operational capability is envisioned for 2028, and recent tests have been highly successful. The alternative to Golden Dome—continued underinvestment in homeland defense while adversaries field ever greater capabilities—is not an option for protecting the United States in this new age of warfare.
Although affordable and on track to field initial operational capability by 2028, success is not assured. Today, Golden Dome is funded through the reconciliation process, meaning the program lacks a traditional budget line to fall back on if a continuing resolution is likely. Continued progress and success require near-term congressional action to remove Golden Dome from the negative consequences of the continuing resolution process. Golden Dome requires predictable, stable funding through a multiyear fiscal appropriation plan. As General Mike Guetlein stated during his keynote address at the recent Space and Missile Defense Symposium, “If they don’t figure it out, there is no Golden Dome because there is no funding.”
Congress Must Secure the 2028 Capability
Golden Dome will not be impenetrable. No static defense system ever has been and likely ever will be. It will, however, erode adversary confidence in any conviction that it can achieve strategic goals by attacking the homeland. Creating doubt in the mind of the enemy will bolster strategic stability and deterrence for our country. Today, a robust homeland defense capability—Golden Dome—is not an option; it is an absolute necessity.
