TESTIMONY: Golden Dome, $350 Billion — the Shield That Divides America

Introduction: Washington, June 2026 — a Cold War Budget in Congress

The Pentagon's disclosure of its spending plans

On June 24, 2026, the Pentagon disclosed to a Congress already saturated by budget debates its spending plan for the first tranche of the One Big Beautiful Act (OBBA): $153.3 billion for fiscal year 2026, to which a further $1 billion under the Defense Production Act was added, according to Inside Defense. In any other context, this plan would have been the lead story in every economic outlet. But Pete Hegseth, Secretary of Defense, wanted far more.

The same day, Politico reported that Hegseth was losing the battle he was waging with Republican lawmakers to unlock an additional $350 billion through a third budget reconciliation. That $350 billion is the heart of the Golden Dome project — the continental American missile defence shield that the Trump administration has presented as the definitive answer to ballistic threats from China, Russia, Iran and North Korea. The project divides Republicans themselves, and its strategic implications extend far beyond American territory alone.

What Golden Dome is — and why it unsettles Moscow and Beijing

Golden Dome is a monumental vision: a multi-layered missile defence system covering the entire continental United States, combining ground-based interceptors, space-based interception systems, high-energy lasers and an integrated networked command architecture. Designed to make the United States impervious to intercontinental ballistic missiles, the programme awakens deep fears in Moscow and Beijing: if the United States is no longer vulnerable to nuclear strike, the mutually assured destruction (MAD) that has structured global security since 1945 is fundamentally called into question.

Admiral Paparo, commander of INDOPACOM, for his part requested an additional $122 billion to counter China in the Indo-Pacific — including $67.4 billion for long-range missiles, $18 billion for electronic warfare and $15 billion for space-based warning systems. These requests are separate from Golden Dome but are part of the same massive rearmament that the Trump administration is attempting to fund.

The American Defence Budget in 2026: Numbers That Stagger

From $838 billion to $1.15 trillion, then $1.5 trillion

To understand the $350 billion being sought for Golden Dome, it must be placed within the overall budget architecture. The "baseline" American defence budget for fiscal year FY2026 stood at $838 billion before the OBBA, according to KPMG on June 22. The OBBA adds $153.3 billion, bringing the total to approximately $991 billion. The proposed FY2027 budget already stands at $1.15 trillion. And the stated target for 2027 is $1.5 trillion.

These figures represent a historic break with American defence spending levels since the end of the Cold War. For the first time in decades, the United States is preparing to spend on defence a sum that surpasses, in absolute terms, the levels reached at the Cold War peak. This massive budgetary reorientation reflects a conviction shared across both parties in Washington: America is in systemic competition with powers — primarily China — that threaten its military supremacy.

The $350 billion additional: a battle in Congress

The request for an additional $350 billion for Golden Dome through a third reconciliation is meeting resistance within the Republican camp itself. Senator John Cornyn, according to the TaxProf Blog on June 20, said this third reconciliation "doesn't have much life in it." That phrasing, in Washington political parlance, is a strong signal: the enthusiasm is not there, and fiscally conservative Republicans are looking at these figures with growing anxiety over their impact on the national debt.

Hegseth, making the rounds of Republican caucuses to sell this programme, according to Politico, finds himself in an uncomfortable position: defending a $350 billion project before members of his own party who ask how much it will cost, whether it actually works, and who will pay. These are legitimate questions. And the fact that the Secretary of Defense struggles to answer them convincingly says something about the political solidity of this monumentally expensive project.

The Technological Foundations of Golden Dome: Promise or Reality?

What Golden Dome is supposed to do — and what actually exists

Golden Dome as presented by the administration rests on several technologies at very different stages of development. Ground-based ballistic interceptors in Alaska and California exist and have been tested, with mixed results. The new layers of Golden Dome — space-based interceptors, high-energy lasers, advanced early-warning detection systems — are for the most part still at the development or preliminary demonstration stage. Promising a "complete" shield by a given date, at a fixed cost, using not-yet-mature technologies, is a technologically bold undertaking.

Admiral Paparo, in his request for $15 billion for space-based missile warning systems, illustrates the spatial component of the project: constellations of satellites capable of detecting missile launches within their first seconds of flight, giving interception systems the maximum reaction time. This space dimension is the most technologically promising — but also the most vulnerable to adversaries' anti-satellite attacks.

The $18 billion for electronic warfare: the real priority

The request for $18 billion for electronic countermeasures and cyber capabilities against the PLA is perhaps the most credible and most urgent component of the entire package. Electronic warfare — the ability to jam, deceive and disrupt adversary guidance systems — is a mature technology, deployable in the short term, and one that has demonstrated its operational effectiveness in the war in Ukraine. Investing massively in this domain means building capabilities that exist and work, not technological promises with uncertain timelines.

The combination of investment in electronic warfare and space-based warning systems forms, in reality, the strongest core of the Paparo-Golden Dome proposal. But politically, these components lack the narrative prestige of a "space shield" that protects all Americans. And in Trump's Washington, the narrative counts as much as the actual capabilities.

Moscow and Beijing React: The End of MAD?

The Russian calculation facing the American shield

For Moscow, Golden Dome is the materialisation of a decades-old strategic nightmare: an America no longer vulnerable to Russian nuclear strike, able to act more freely in regional crises without fearing ultimate escalation. Mutually assured destruction functioned throughout the Cold War because each side knew the other could destroy it entirely. An effective Golden Dome would break that symmetry — and with it, the nuclear brake that has prevented major powers from confronting each other directly.

Russia's response will be predictable: accelerate the development of hypersonic missiles designed to circumvent any missile shield, invest in saturation weapons capable of overwhelming even the most sophisticated defences, and use the Golden Dome rhetoric politically to justify its own nuclear modernisation programmes before its domestic audience and the countries it seeks to align behind it.

The Chinese calculation: accelerating nuclear modernisation

For China, the logic is similar but with an additional dimension. China seeks to develop a credible second-strike nuclear capability — the ability to retaliate massively even after absorbing an initial American strike. An effective Golden Dome would directly threaten that capability, pushing China to expand its nuclear arsenal and invest in hypersonic technologies to guarantee penetration of its missiles through any potential shield.

The Claw Street Journal on June 21, 2026, in its analysis of NATO realignment in the face of three simultaneous crises, highlighted that Golden Dome creates a strategic instability that is hard to contain: every dollar invested in an American defensive shield generates multiple dollars of adversary offensive investment to circumvent it. The net result is not necessarily more security — it is more armaments on all sides, in a competitive escalation logic whose ultimate outcome is difficult to predict.

Hegseth Facing the Republicans: American Domestic Politics

A Secretary of Defense struggling to convince

Pete Hegseth's difficulty in convincing Congressional Republicans on the third reconciliation reveals a fundamental tension within the 2026 Republican Party. On one side, the Trumpist base wants a muscular "America First," a massive rearmament that restores American "greatness" — that is the Golden Dome narrative. On the other, fiscally conservative Republicans look at the growing national debt, recurring deficits, and ask whether America can truly afford simultaneously massive tax cuts and a historic rearmament without severe economic consequences.

Cornyn's comment — "doesn't have much life in it" — crystallises that tension. The $1.5 trillion defence budget envisioned for 2027 represents a level of spending that, combined with the OBBA's tax cuts, produces fiscal deficits that even the most accommodating conservative economists find troubling. Budget arithmetic is relentless, even for the most politically determined administration.

The defence industry lobbying

Behind the budget debates in Congress lie the very concrete interests of America's defence contractors. Lockheed Martin, Northrop Grumman, Raytheon, Boeing Defense — all these players have a substantial portion of their future growth tied to Golden Dome coming to fruition. Their lobbying teams are working the corridors of Capitol Hill in parallel with Hegseth's teams. In an American political system where campaign financing is intimately tied to major industrial donors, the $350 billion of Golden Dome is not solely a national security issue — it is also an economic and political issue of considerable scale.

This dimension does not disqualify the project in itself — defence contractors can produce useful systems while maximising their contracts. But it invites a critical eye toward cost projections, announced timelines and promised performance levels. The history of major American defence programmes is dotted with spectacular overruns: the F-35, the Ground-Based Midcourse Defense missile programme, the USS Ford — all cost more and delivered later than planned.

The Implications for Europe and Ukraine

An American shield that reshapes NATO calculations

Golden Dome has a dimension directly relevant to NATO and Europe. If the United States develops a continental missile shield, the question of coverage for European allies arises immediately. NATO's Article 5 commits the United States to defend its allies — but an American missile shield protects American territory, not necessarily that of Germany, France or Poland. Is an America invulnerable to Russian ballistic missiles not also an America potentially less engaged in defending allies that have no equivalent shield?

This potential asymmetry reinforces the argument of proponents of European strategic autonomy: if American protection is increasingly national-American and decreasingly transatlantic, Europe must develop its own missile defence capabilities. That need is added to the already long list of defence investments that European NATO members must make to reach the targets discussed at the Ankara summit.

What Golden Dome means for Ukraine

For Ukraine, the Golden Dome programme carries a specific significance: if advanced American missile interception technologies advance, they could eventually be shared or adapted to reinforce the Ukrainian air defence shield against Russian ballistic missiles. The request for $15 billion for space-based warning systems in particular — capable of detecting missile launches within the first seconds of flight — is exactly the type of capability Ukraine would need to improve its warning times against Russian ballistic strikes that have proven so lethal for civilians in recent months.

But this remains hypothetical. In the short term, resources devoted to Golden Dome are not resources devoted to military aid for Ukraine. And in a Congress that struggles to fund both simultaneously, American national priorities tend to take precedence over external commitments, however strategically justified they may be.

Golden Dome Against the Geostrategic Realities of 2026

Hypersonic missile proliferation: the central challenge

Golden Dome must respond to a threat that evolves faster than its own interception technologies. Hypersonic missiles — Russia's Avangard, China's DF-17, and the programmes under development in Iran and North Korea — are designed precisely to render current interception systems obsolete. These missiles travel at speeds exceeding Mach 5, can manoeuvre in mid-flight and follow unpredictable trajectories that radically complicate interception. Golden Dome, as presented, will need to invest massively in hypersonic interception technologies to remain relevant.

Admiral Paparo and his team are aware of this: that is why the $67.4 billion for long-range missiles includes investment in interceptors capable of engaging hypersonic targets. But the technological race between offensive missiles and defensive systems is never definitively won — it is permanent and costly. Russia and China will devote increasing resources to developing vectors that slip under Golden Dome's radar, creating an investment spiral whose outcome remains uncertain.

Early-warning satellites: the most promising layer

Among the components of Golden Dome, the $15 billion requested for space-based warning systems are probably the best technically justified. Modern early-warning satellites, capable of detecting missile launches within seconds from the infrared signature of engines, provide invaluable warning to interception systems and civilian populations. These technologies exist, work, and can be deployed in a relatively short time frame compared to the other components of Golden Dome.

For Ukraine, this dimension is particularly relevant. A network of early-warning satellites shared with the Alliance would significantly improve Ukrainian warning times against Russian ballistic missiles — reducing civilian casualties and enabling faster activation of air defence systems. The $15 billion invested in these satellites would therefore benefit not only American continental defence but all allies who share the space surveillance infrastructure.

The Industrial Economy of American Defence: Who Really Wins

Defence contractors and the $350 billion windfall

Behind the budget debates in Congress lie the very concrete interests of America's defence contractors. Lockheed Martin, Northrop Grumman, Raytheon, Boeing Defense — all these players have a substantial portion of their future growth tied to Golden Dome coming to fruition. Their lobbying teams are working the corridors of Capitol Hill in parallel with Hegseth's teams. In an American political system where campaign financing is intimately tied to major industrial donors, the $350 billion of Golden Dome is not solely a national security issue — it is also an economic and political issue of considerable scale.

This dimension does not disqualify the project in itself — defence contractors can produce useful systems while maximising their contracts. But it invites a critical eye toward cost projections, announced timelines and promised performance levels. The history of major American defence programmes is dotted with spectacular overruns: the F-35, the Ground-Based Midcourse Defense missile programme, the USS Ford — all cost more and delivered later than planned. There is no structural reason to believe Golden Dome will be different.

The $15 billion for early-warning satellites: the most defensible investment

Among all components of Golden Dome, the $15 billion for space-based missile warning systems represents the most technically credible investment. Early-warning satellites detecting launches within seconds from engine infrared signatures are mature, deployable, and provide measurable operational value — not only for American continental defence but for the entire Alliance. Finland, the Baltic states, Ukraine itself would benefit from faster warning times against Russian ballistic launches.

This component also carries a lower escalation risk than the offensive-capable intercept layers of Golden Dome. Warning systems are transparently defensive; they do not threaten Russia's or China's second-strike capacity in the way that kinetic interceptors do. If Congress were to fund only one layer of Golden Dome, making early-warning satellite infrastructure the priority would deliver the greatest strategic return per dollar, benefit the widest circle of allies, and avoid the worst instability dynamics of a fully realised missile shield.

Conclusion: A Historic Programme, Legitimate Questions

What Golden Dome says about America in 2026

Golden Dome reflects an America that has recognised, after decades of post-Cold War "peace dividend," that military security must be actively maintained and funded. That recognition is in itself healthy and necessary. China is arming massively, Russia is bombarding Eastern Europe, Iran is developing ballistic capabilities, North Korea is testing ICBMs — the strategic environment has deeply degraded, and democracies must adapt.

But between recognising the need to rearm and approving a $350 billion programme for partially proven technology, through a budgetary mechanism that Republicans themselves find politically dubious, there is a space for legitimate questioning. America can afford to spend $350 billion — the question is whether it is the best possible investment for American security and that of its allies.

The real question: security for whom, and how?

Security is not only a question of shields and missiles. It is also a question of solid alliances, resilient economies, consolidated democracies, and collective will to defend shared values. Golden Dome, even perfectly executed, does not make America safer if its European allies are abandoned in the face of Russian pressure, if Ukraine is left without missiles for the winter, or if China extends its global technological influence while Washington debates its budget credits. National security is never an island: it is always the reflection of the quality of the alliances one maintains and the commitments one keeps.
