Navigating the Post-Shutdown Defense Budget Landscape

Portions of the federal government that shut down over the weekend reopened on Tuesday with the signing of a multi-bill appropriations package. Most of the government is now fully funded through the remainder of fiscal year 2026, including the Pentagon, but the Department of Homeland Security only has funding through February 13.  A quick end to the shutdown wasn’t guaranteed, as tensions over the administration’s immigration crackdown threatened to derail the broader budget process. However, ongoing discussions about DHS funding were ultimately separated from the other government spending bills.

The House initially passed a minibus spending package last month that included funding for defense; DHS; Labor, Health and Human Services, Education; and Transportation, Housing and Urban Development. These departments were excluded from the prior spending agreement that terminated the 43-day shutdown that occurred between October and mid-November 2025. The Senate passed a modified version of the minibus Friday that separated DHS funding. Since the legislation differed from the House’s original package, it had to go back to the House for approval. The House was not in session over the weekend, resulting in the partial shutdown, but lawmakers passed the legislation Tuesday afternoon, sending it to the president’s desk for a final signature.

The president’s signature ends what has been one of the most tumultuous budget processes in recent history. To start with, the initial budget request was released nearly five months late because of the change in administration. Lawmakers broke with precedent to use budget reconciliation to provide the Pentagon with funding outside of the regular appropriations process. The supplemental reconciliation funding was ultimately integrated into the administration’s FY26 request. However, this approach caused confusion due to a lack of detailed justification materials outlining how reconciliation dollars would be spent. Finally, the Pentagon was subject to the longest government shutdown in history, followed by a brief lapse in funding over the weekend. The mix of base and supplemental reconciliation funding, along with delays and tense negotiations, resulted in a complex and often confusing process.

What does the spending bill provide?

The appropriations package signed into law this week reflects the final enacted budget for the Pentagon in FY26. The new appropriations bill adds $8.5 billion to the base defense budget, increasing it to $839.2 billion. The Pentagon’s base budget reaches $858.9 billion after including $19.7 billion for military construction funded in a separate appropriations bill.

The topline adjustment masks a more substantial increase for the development and procurement of new weapon systems. The legislation adds $14.4 billion for procurement and $3.9 billion for research and development, for a total influx of $18.3 billion in acquisition funding above the request. The additional acquisition funding is partially offset by reductions of $1.4 billion for personnel, $1.3 billion for operation and maintenance, and $8.8 billion in general provisions. The latter includes $5.7 billion in rescissions of prior year appropriations spanning multiple procurement accounts, softening the increase provided in FY26. A significant portion of rescinded funding, some $2.4 billion, applies to the Constellation class program recently terminated by the Navy in favor of a new frigate based on the Coast Guard’s National Security Cutter.

The Pentagon also has access to over $150 billion from last year’s reconciliation bill, but it will take time to determine precisely how that money is allocated.

Looking to Forward FY27

With the FY26 budget finally wrapped up, the focus now turns to FY27. Federal law dictates that the annual federal budget request is released on the first Monday in February, which this year was February 2. That date came and went with no sign of a new request.

Budget requests can be delayed for several reasons. The FY26 request was nearly five months late following a change in administration, beating a four-month delay for President Biden’s first budget. Other issues can also lead to postponed requests as well. First among them is slow action on the previous year’s appropriations bill. Congress regularly fails to pass budgets on time. Nevertheless, extensive delays in finalizing annual appropriations make it even harder for budget planners to finalize the next request. In the case of the FY25 budget, the Biden administration proceeded with submitting its request even though Congress had not finalized FY24 appropriations.

The government might also delay a budget request if it is planning to integrate major changes. Trump recently announced a desire to increase the FY27 defense budget to $1.5 trillion, which is likely to contribute to delays. It’s unclear if the administration will seek a base budget of $1.5 trillion or work with Republican lawmakers on a second reconciliation bill to increase FY27 spending, or some other strategy or combination of approaches. It also remains to be seen whether the $1.5 trillion figure is a firm target or part of a negotiation tactic, as that figure would represent a massive 50 percent increase in a single year. Either way, the administration appears to need more time to finalize its approach to FY27 spending levels. The White House hasn’t outlined a planned release date for the FY27 request, but it’s possible it could be delayed until March or even later.

For now, we’ll continue digging into the completed FY26 defense legislation to learn more about how investments and opportunities will be impacted over the coming years.
