Nuclear Weapons:

Budget: The House of Representatives passed a fiscal 2027 continuing resolution to keep the government running through Dec. 4 (the new fiscal year begins Oct 1). The White House Office of Management and Budget is requesting a series of anomalies, or exceptions, to the CR rule that funding be limited to the levels of the prior fiscal year. One anomaly is for the new Trump-class battleship.

For the National Nuclear Security Administration (NNSA): it’s the Electrical Power Capacity Upgrade (the new powerline across the Caja del Rio); enhanced subcritical tests at the Nevada National Security Site; and, most dangerous of all, allowing the NNSA to reprogram funding by itself within its Total Weapons Activities budget category.

The Senate is basically doing the same, plus an anomaly for ‘‘21– D–401 Hoisting Capability Project’’ at the Waste Isolation Pilot Plant. WIPP has been operationally shut down for a few months now due to a burnt-out hoist motor.

The House and Senate must resolve their relatively minor differences and get Trump’s signature before October 1 to prevent a government shutdown.

Regular authorization (the annual Defense Authorization Act) and appropriations are unlikely to move until mid-term elections (~86 days to go).

Plutonium pit production:

We filed suit under the Freedom of Information Act (FOIA) for DOE’s “Special Study.” See https://nukewatch.org/wp-content/uploads/2026/08/Nuclear-Weapons-Watchdog-Sues-for-Pit-Production-Special-Study.pdf
The South Carolina Environmental Law Project sent a letter to DOE/NNSA demanding 3 crucial documents: the “Special Study,” the unclassified summary of the new JASON pit life study, and LANL’s new Probabilistic Seismic Hazard Analysis. See our press release at https://nukewatch.org/wp-content/uploads/2026/07/Plaintiffs-Demand-Release-of-Critical-Documents-and-Extension-of-Public-Comment-Period-on-Expanded-Plutonium-Bomb-Core-Production.pdf
The Pit Production PEIS comment period ended July 16 (81^st anniversary of the Trinity Test). We submitted 64-page comments plus exhibits, see nukewatch.org/wp-content/uploads/2026/07/Formal-Comments-on-the-Pit-Production-Programmatic-Environmental-Impact-Statement.pdf NNSA ignored our demand for a comment period time extension because of the withheld documents.
We received an unredacted version of the new JASON pit life study (see https://nukewatch.org/wp-content/uploads/2026/08/2026-JASON-Plutonium-Aging-Executive-Summary.pdf). “High Level Finding:… “The Pu in the stockpile appears to be aging slowly. The degradation issues that have been observed do not call into question present weapons performance.” We had received one title page and 2 completely blank narrative pages the day before the PEIS comment period expired.

Now, Republicans are competing to bring it home. The Department of Energy announced last week that it had signed memorandums of agreement with Utah, Tennessee, Oklahoma, Louisiana and Idaho to explore creating facilities to support the full nuclear fuel cycle — from enrichment of uranium and fabricating fuel to disposing of waste. Rather than resisting an initiative that could bring more nuclear waste to their states, some Republicans are actively courting the Nuclear Lifecycle Innovation Campuses, arguing they could anchor advanced nuclear industries and bring billions of dollars in investment.

The new strategy, which is classified, challenges the approach to nuclear weapons that has been settled policy for decades… Colby has long pushed for an emphasis on tactical weapons, arguing that America’s adversaries would simply not believe the U.S. would seriously contemplate launching long-range weapons aimed at wiping out an enemy’s nuclear forces — as is the emphasis of the

Poland, Finland, and Lithuania are under consideration as potential host countries, according to Süddeutschen Zeitung on July 31. The discussions include Poland aiming to join the Nuclear Sharing program, Finland lifting its long-standing prohibition on nuclear weapons transit and import, and the Lithuanian parliament reviewing legislation to remove its constitutional ban on nuclear deployments.

Although the administration has not yet released the full text, the agreement reportedly will not require Riyadh to categorically forgo fuel cycle activities that would be conducive to a nuclear weapons program (namely enrichment and reprocessing) or to accept the highest standard of International Atomic Energy Agency (IAEA) safeguards, known as the Additional Protocol, or AP.

Nuclear Weapons Issues & The Accelerating Arms Race: June 2026

Nuclear Weapons:

Budget: Record $1 trillion military budget. Now Trump wants a reconciliation bill that adds $350 billion. He also wants the “Save America” voter suppression Act attached to it which is bound to be ruled not proper by the Senate parliamentarian (reconciliation bills are supposed to deal only with the budget). This could lead to a crisis of some kind.

Favorable polling for Trump is going down with the war in Iran and economic impacts. Will voter suppression will be the only thing that keeps Republicans in control of Congress?

There is also talk of $80 billion supplemental appropriation for the war in Iran.

Defense Authorization Act:

Passed by House, Senate is considering.
Hard line House congressional Trumpers want the Save America Act attached to the DAA. That would kill its passage in the Senate and probably won’t happen.
Proposed 180 pits per year by 2050.
Numerically expands the US nuclear weapons stockpile to deal with the alleged China threat. This will probably result in MIRVing of land-based intercontinental ballistic missiles (ICBM) and more warheads on already MIRVed sub-launched warheads.
Proposes to more closely integrate US and Israeli military and guarantee $3 billion per year to Israeli military.

Overall trend very bad. Welcome to the new nuclear arms race.

New Nuclear Bunker Buster Bomb Plans Revealed The Department of Energy is seeking millions of dollars for work in part on a new bunker-busting nuclear weapon called the Nuclear Deterrent System-Air-delivered (NDS-A) in its latest budget request… Beyond that it will be air-delivered, there are also no details currently available publicly about the weapon’s design, including whether it will be based on something already in the stockpile.

See the graph below found on the Kansas City National Security Complex website. There are three future new-design nuclear weapons on the right above the W93 (“F” is all 3 cases means “Future”). These new-design nuclear weapons presumably will have new-design pits like the W93.

Independent Government Accountability Office Releases Scathing Report on Expanding Plutonium Pit Production; Pressure Mounts on Los Alamos Lab to Increase Production

Santa Fe, NM – Today, the independent Government Accountability Office (GAO) released a scathing report entitled NNSA Does Not Have a Comprehensive Schedule or Cost Estimate for Pit Production Capability. The National Nuclear Security Administration (NNSA) and its parent Department of Energy have been on the GAO’s High Risk List for project mismanagement since 1991.

Plutonium pits are the essential radioactive cores of nuclear weapons. There has been only limited production at the Los Alamos National Laboratory (LANL) since 1989 when a FBI raid investigating environmental crimes abruptly shut down production at the Rocky Flats Plant near Denver. NNSA now plans to spend $2.9 billion in FY 2023 alone to establish production of at least 30 pits per year at LANL and 50 pits per year at the Savannah River Site (SRS) in South Carolina.

The two main findings of GAO’s report are:

NNSA’s Plutonium Pit Production Scope of Work Includes Dozens of Programs, Projects, and Other Activities Managed by Multiple NNSA Offices at Multiple Sites (p 19)

Good article indeed. Kudos to Scott Wyland.

But to add to it:

The National Nuclear Security Administration (NNSA) cannot do, or rather will not do, good governance 101 for its largest program ever (i.e., expanded plutonium pit production), which is credible cost estimates and schedules. Why won’t NNSA do that? Because of PR and political concerns when their flaky cost estimates (such as they are) get blown up by inevitable escalating costs. NNSA knows that if it gave accurate projected costs Congress and the public would balk. Thus, the agency goes in lowballing costs, which always inevitably rise. I could rattle off a dozen NNSA projects over the last 15 years in which costs have exploded, wasting tens of billions of taxpayers’ dollars.

But get this, future pit production is also unnecessary and may actually degrade national security. To begin with, independent experts have found that pits have serviceable lifetimes of at least a century (their average age is now around 40). And we already have at least 15,000 existing pits stored at the Pantex Plant near Amarillo, TX.
