Record U.S. Nuclear Arms Spending Hits $119 Billion in 2025

The latest figures from the International Campaign to Abolish Nuclear Weapons (ICAN) reveal that the United States’ annual budget for nuclear weapons grew by 19% in 2025, topping $119 billion. This amount not only eclipses the previous record set in 2024 but also places the U.S. well beyond the total expenditures of the other eight nuclear‑armed countries combined.

At the heart of the spend surge is the United States itself, which allocated $69.2 billion to its nuclear arsenal—an increase of 22% from the prior year. Analysts say the higher expenditure reflects a broader uptick in U.S. defense budgets and a strategic shift toward rebuilding and modernizing its nuclear stockpile.

China has not been left behind. Its share rose 7% to $13.5 billion. Britain caught up to Russia in ranking third; its own spend climbed by 17% to $12.6 billion, surpassing Russia’s $9.5 billion allocation, which grew by 6%. 

ICAN has long advocated for the total elimination of nuclear weapons. In its report, it noted that 2025 marks the highest global spending on nuclear arms since the organization began tracking the nine nuclear‑armed states in 2020.

These figures come at a time of heightened geopolitical uncertainty. With complex security challenges on both the eastern and western frontiers, policymakers in Washington are weighing the costs and benefits of sustaining such a formidable arsenal. Critics argue that the money could be redirected toward humanitarian initiatives, while proponents maintain that a powerful deterrent is essential for national security.

Despite the controversy, the data underscore a clear trend: nuclear weapons remain a top priority in U.S. defense spending. The implications of this trend will reverberate across international diplomacy, arms control negotiations, and the ongoing debate over how best to balance military readiness with global peace efforts.
