America’s Nuclear Weapons Footprint Reaches Every State. Public Oversight Should Reach It, Too.

A new map gives communities a starting point for examining the costs, consequences and security claims of the nuclear weapons enterprise.

America’s nuclear weapons debate often centers on threats abroad. A new mapping project brings it home, tracing a network its creators say reaches every state.

According to an October 22 announcement, the digital resource at NuclearImpacts.org documents nearly 4,000 sites connected to U.S. nuclear weapons, from uranium mining to military installations and radioactive waste storage. Its creators say it draws on publicly available, unclassified government records, reporting and community interviews.

That geographic reach gives the project significance beyond any single facility. It offers a way for residents to connect a national security enterprise with places they recognize—and begin asking how its benefits, costs and responsibilities are assessed.

The map does not settle whether a particular weapons program makes the country safer. It helps make the physical infrastructure - and its impact on U.S. communities - behind that debate more visible.

Seeing the places behind the spending

The sums involved are substantial. In an April 2025 assessment, the Congressional Budget Office estimated that plans described in the fiscal year 2025 budget requests to operate, sustain and modernize U.S. nuclear forces over the coming ten years would cost $946 billion.

That was a projection based on specified plans, rather than a final accounting or a measure of security gained. It covered weapons, delivery systems, supporting infrastructure and other activities, including an allowance for potential cost growth.

The National Nuclear Security Administration describes the U.S. nuclear weapons stockpile as essential to deterrence: discouraging attacks and reassuring allies through a credible capacity to retaliate. Its stated responsibilities include keeping weapons safe, secure and reliable.

Those objectives explain the government’s case for the enterprise. Assessing the case also requires examining execution, alternatives and consequences. A budget total cannot show whether a project met its purpose, whether a less costly approach was available or whether neighboring communities received adequate protection.

Secrecy has shaped public understanding

There is a documented basis for public concern about what has remained hidden. The Energy Department says its 1993 openness initiative disclosed previously secret nuclear tests, along with information about plutonium holdings and mercury used in weapons production.

That history does not mean every present-day record is unavailable. The new project itself relies partly on public government sources. Federal agencies also publish budgets, environmental information and oversight reports. The information available today is in part a result of public pressure over decades, such as through the landmark citizen science baby tooth campaign, for the U.S. government to share what it knows and investigate further where warranted.

The accountability challenge is to make that information usable and identify what remains missing. Residents should be able to distinguish a necessary restriction on sensitive weapons information from an unanswered question about contamination, cleanup or public spending.

According to the release, the map’s content and data, including site coordinates, are publicly downloadable, and the creators plan to continue updating the map. If maintained with clear sourcing and corrections, that can help local journalists, researchers and communities check records and connect findings across locations.

Public records already reveal oversight gaps

Independent federal reviews show why such scrutiny matters. A March 2026 GAO report on Energy Department cleanup found problems with the completeness and consistency of cost and schedule information. Officials could not easily reconcile discrepancies, complicating accurate reporting to Congress.

GAO reported that the department’s Office of Environmental Management estimated more than half a trillion dollars in remaining cleanup work as of May 2025. Its responsibilities cover contamination from both nuclear weapons production and nuclear energy research; that figure is not a price tag for the map’s sites.

Future activities bring their own questions. A 2024 GAO review of NNSA’s waste strategy found that its long-range outlook omitted anticipated waste from important activities, including reestablishing plutonium pit production. GAO recommended a more comprehensive strategy.

These findings do not establish that every nuclear investment is ineffective. They identify specific information and management gaps that impede informed judgment.

A starting point for better questions

For a resident, the map’s value may begin with a simple discovery: a nearby property had a role in the weapons enterprise. The next questions are more demanding. What happened there? What evidence documents its condition? Who is responsible for any remaining cleanup? How will progress be measured?

A site’s inclusion should prompt investigation, rather than an assumption that every location is contaminated or equally hazardous. The EPA’s uranium cleanup work with Navajo communities, for example, uses site assessments to establish conditions and priorities.

An informed security debate needs room for both the government’s stated objectives and the experience of the people living with its infrastructure. Making that infrastructure easier to see is one step toward giving the public a stronger basis for judgment.
