Nine countries possess nuclear weapons. The combined annual cost of maintaining their arsenals exceeds $150 billion. Here's the breakdown by country, what arms control has saved, and the economic case for and against disarmament.

The International Campaign to Abolish Nuclear Weapons (ICAN) estimates that the nine nuclear-armed states spent a combined $91.4 billion on nuclear weapons in 2023 — a figure that has risen significantly from prior years as modernization programs accelerate. Including the full infrastructure of nuclear command, control, communications, intelligence, and base support, estimates of total nuclear-related spending run considerably higher.
Breaking this down by country provides a clearer picture of how the economics of deterrence are distributed — and how dramatically different the burden is across the nine members of what might be called the nuclear club. This builds on nuclear deterrence economics and connects to the economics of military spending broadly.
United States ($51.5 billion/year): By far the largest nuclear spender. The U.S. is in the midst of a 30-year, $1.7 trillion nuclear modernization program that replaces all three legs of the triad simultaneously for the first time: the Ground Based Strategic Deterrent (replacing Minuteman III ICBMs, $125 billion), Columbia-class SSBNs (replacing Ohio-class submarines, $132 billion for 12 boats), and B-21 Raider stealth bomber (replacing B-2, estimated $80+ billion for 100 aircraft). The scale reflects both the age of current systems (many date to the 1970s-80s) and the decision to maintain the full triad rather than consolidate.
Russia (~$9-10 billion/year): Russia has the world's largest nuclear arsenal by warhead count (approximately 5,580 total, of which roughly 1,550 are deployed strategic warheads). Russian nuclear spending is harder to verify given defense budget opacity, but its modernization programs are real: the RS-28 Sarmat ICBM (capable of delivering 10-15 warheads at intercontinental range), Avangard hypersonic glide vehicle (maneuvering re-entry vehicle that evades missile defenses), Poseidon nuclear-armed autonomous underwater vehicle, and Kinzhal air-launched hypersonic missile. Russia is using nuclear modernization partly as a strategic signaling tool — developing weapons designed to penetrate U.S. missile defenses and maintain deterrence credibility despite Russia's economic disadvantages relative to the U.S.
China (~$11.7 billion/year, rising rapidly): China's nuclear modernization is the most significant change in the global nuclear balance in decades. From approximately 300 warheads in 2020 to an estimated 500+ in 2024, with the Pentagon projecting 1,000+ by 2030. New ICBM silos (over 300 identified by commercial satellite imagery in 2021), expansion of the Jin-class SSBN fleet, and development of the H-20 stealth bomber suggest China is moving toward a genuine triad. The pace of expansion has changed the strategic calculus significantly.
UK (~$6.2 billion/year): The UK maintains the minimum credible deterrent — approximately 225 warheads, all SSBN-delivered via Trident II D5 missiles. The Dreadnought-class SSBN replacement program (£31 billion estimated) will maintain this posture for decades. UK policy specifies it will not use nuclear weapons first against non-nuclear states that are members of the Non-Proliferation Treaty.
France (~$6.0 billion/year): France maintains an independent deterrent (force de frappe) of approximately 290 warheads, SSBN and air-delivered. France is unique among NATO members in maintaining complete strategic independence — its weapons are not integrated into NATO nuclear planning. The SNLE-3G submarine program will replace current SSBNs by the 2030s.
Pakistan and India (~$1-2 billion/year each): Both maintain arsenals of approximately 160-170 warheads with ongoing delivery system development. Pakistan has focused on developing tactical nuclear weapons — shorter-range systems designed for battlefield use against conventional Indian military forces. India maintains a credible minimum deterrent with a declared no-first-use policy. The India-Pakistan nuclear standoff is considered by many analysts to be the highest-risk nuclear situation globally, given their history of conventional military conflict.
Israel (~$1 billion/year estimated): Israel maintains a policy of nuclear ambiguity — neither confirming nor denying nuclear weapons possession. The existence of an Israeli arsenal of approximately 90 warheads is widely accepted by intelligence analysts based on circumstantial evidence and whistleblower testimony (Mordechai Vanunu's 1986 disclosures to the Sunday Times). Israel is not a signatory to the NPT.
North Korea (~$400-500 million/year): North Korea has conducted six nuclear tests and is estimated to have 40-50 warheads, with production capacity expanding. Its missiles — Hwasong-15 and Hwasong-17 ICBMs — are assessed to have the range to reach the continental U.S. North Korea's nuclear program consumes a disproportionate share of a national budget of approximately $4 billion — a country willing to accept mass poverty to maintain nuclear status.
At the Cold War's peak (1986), the U.S. and Soviet Union collectively possessed approximately 70,000 nuclear warheads. The world now has approximately 12,500 — a reduction of over 80% achieved through arms control treaties: SALT I and II, INF, START I, Moscow Treaty, New START.
New START (2010, extended to 2026 but suspended by Russia in 2023) limits U.S. and Russian deployed strategic warheads to 1,550 each and deployed delivery vehicles to 700 each. The suspension of Russia's participation following the Ukraine invasion has removed the verification regime that allowed both sides to monitor compliance — a significant step backward for strategic stability.
The cost savings from arms control are real: fewer warheads means fewer delivery systems, less maintenance, less storage, and less infrastructure. The U.S. at its Cold War peak maintained over 31,000 warheads. Maintaining the current arsenal of approximately 5,500 (most in reserve) at Cold War quantities would cost multiples of current spending. The economic case for arms control is straightforward — less spending for equivalent deterrence. The political case is harder, because trust between adversaries is required to verify compliance and because domestic political constituencies benefit from nuclear spending.
