The U.S. plans to spend $1.7 trillion modernizing its nuclear arsenal over 30 years. Russia, China, UK, France, and Pakistan maintain their own. Here's the full economic picture of nuclear weapons — what they cost, who benefits from the industry, and whether deterrence is getting more expensive.

Nuclear deterrence is the theory that the threat of catastrophic retaliation prevents adversaries from launching nuclear attacks. The practice is maintaining weapons that can never be used without producing civilization-ending consequences, at costs that would fund the equivalent of universal healthcare for a mid-sized country, in the hope that their existence makes the scenario they're designed for impossible.
The U.S. Congressional Budget Office estimated in 2023 that the U.S. would spend approximately $756 billion on nuclear forces over the next decade and approximately $1.7 trillion over 30 years — including modernization of all three legs of the nuclear triad. This is what deterrence costs. Understanding where that money goes, and how the economics of nuclear weapons maintenance work, is essential context for any analysis of the defense budget.
This connects to total U.S. military spending and to defense contractor economics.
The U.S. nuclear deterrent rests on three delivery systems — the triad — each maintained by a different set of contractors and programs:
Land-based ICBMs: The current Minuteman III ICBM fleet, deployed in silos across Montana, North Dakota, Wyoming, Colorado, and Nebraska, is being replaced by the Sentinel ICBM (formerly Ground Based Strategic Deterrent). Northrop Grumman won the Sentinel contract in 2020; the program has already experienced cost growth from $85 billion to over $140 billion before a single missile is deployed. Sentinel is expected to cost significantly more than original estimates — the GAO designated it a 'major defense acquisition program in breach' in 2024 due to cost overruns exceeding 25%.
Submarine-launched ballistic missiles (SLBMs): The 14 Ohio-class nuclear-armed submarines (SSBNs), each carrying up to 20 Trident II D5 missiles, are the most survivable leg of the triad. The Columbia-class SSBN program — replacing Ohio-class submarines over time — is estimated to cost approximately $109 billion for 12 submarines. General Dynamics Electric Boat and Huntington Ingalls Industries are the prime constructors. The Trident II missile life extension program (run by Lockheed Martin) extends the missiles' operational life and updates their capabilities.
Strategic bombers: The B-52H fleet, designed in the 1950s and continuously modernized, will fly until the 2050s. The B-2 Spirit stealth bomber (Northrop Grumman) is the current penetrating bomber. Its replacement, the B-21 Raider (also Northrop Grumman), entered flight testing in 2023 and is estimated to cost approximately $750 million per aircraft for the planned 100-aircraft fleet — approximately $75 billion in procurement alone.
The warheads themselves: The Department of Energy's National Nuclear Security Administration (NNSA) maintains the actual nuclear warheads through the nuclear weapons complex — a network of laboratories (Los Alamos, Sandia, Lawrence Livermore) and production facilities (Pantex in Texas for assembly and disassembly, Y-12 in Tennessee for uranium components, Kansas City Plant for non-nuclear components). NNSA's budget is approximately $20-25 billion per year and growing.
All three legs of the triad were designed in the 1970s-1980s. The current modernization program — replacing Minuteman III with Sentinel, Ohio-class with Columbia, B-2 with B-21, and upgrading warheads — is occurring simultaneously for the first time in history. The coincidence of timing is an accident of original design life expectancy; the cost is concentrated rather than spread over time.
Several factors drive modernization costs beyond initial estimates:
Industrial base atrophy: The specialized workforce and manufacturing capabilities required for nuclear weapons production — machining to extreme tolerances, working with special nuclear materials, producing solid rocket motors — shrank dramatically during the post-Cold War drawdown. Rebuilding those capabilities takes time and money, and the smaller workforce commands higher wages for rare skills.
Supply chain concentration: Nuclear weapons components often depend on single-source suppliers who have been maintained at minimal scale for decades. The NNSA's plutonium pit production program — pits are the fissile cores of nuclear warheads — requires expanding production from approximately 10 pits per year to 80 per year. Building that production capacity is a multi-billion dollar, multi-decade effort.
Software and systems integration: Modern nuclear command, control, and communications (NC3) systems require extensive software development and cybersecurity hardening against threats that didn't exist when current systems were designed.
The U.S. is not alone in expanding its nuclear arsenal. Russia, China, UK, France, India, Pakistan, North Korea, and Israel (undeclared) all maintain nuclear forces. The current environment represents the first time since the Cold War that nuclear arsenals are expanding rather than contracting:
China is conducting the most rapid nuclear buildup. The DoD estimates China's warhead count could reach 1,500 by 2035, up from approximately 200-500 currently. The construction of hundreds of new ICBM silos (observed via satellite imagery in Xinjiang and elsewhere) suggests a substantial increase in land-based capacity. China's modernization includes new submarines, a new bomber, and hypersonic delivery vehicles.
Russia has the world's largest nuclear arsenal by warhead count (approximately 5,900 total, ~1,700 deployed strategic warheads under New START counting). Russia has been developing and deploying several new delivery systems: the Sarmat ICBM (replacing Voevoda), Avangard hypersonic glide vehicle, Poseidon nuclear-armed undersea drone, and Burevestnik nuclear-powered cruise missile.
UK announced in its 2021 Integrated Review an increase in its maximum nuclear warhead stockpile from 180 to 260 — the first increase in UK nuclear weapons since the Cold War.
The standard critique of nuclear spending is opportunity cost: $1.7 trillion over 30 years is approximately $57 billion per year. The U.S. federal government spends approximately $50 billion per year on K-12 education title programs. The entire CDC budget is approximately $9 billion. PEPFAR (President's Emergency Plan for AIDS Relief), which has saved an estimated 21 million lives, costs approximately $6 billion per year.
The counterargument: nuclear weapons spending is the cost of a deterrent that has prevented great-power war since 1945 — a 75-year absence of conflict between nuclear-armed powers that is historically unprecedented. If nuclear deterrence has been working, its cost is the insurance premium on avoiding a conflict that conventional war estimates suggest could cost trillions and millions of lives. The math depends entirely on how you value the probability and cost of the war being deterred.
