Inside the $1.5 Trillion Defense Budget: What It Buys, What It Cuts, and What It Can't Deliver

The White House budget proposal for fiscal year 2027 requests $1.5 trillion in total defense resources, an increase of $445 billion. By the administration's own historical tables, this would be the largest national defense budget since World War II in inflation-adjusted terms. Only the war years of the 1940s were higher. ^17,12

The increase is paid for, in part, by cutting nondefense spending by $73 billion, or 10 percent. The administration describes the savings as coming from "reducing or eliminating woke, weaponized, and wasteful programs" and "returning state and local responsibilities to their respective governments." ¹⁸

On the campaign trail, the president said "the pain should be borne by Washington bureaucrats, not by hardworking American families and American seniors." ¹⁵ The budget document makes clear where the pain actually lands: water infrastructure, housing, community services, and the grant pipelines that small municipalities depend on.

This is a proposal, not a law. Congress has to pass it, and presidents' budgets rarely survive intact. But it is detailed enough to trace which programs are cut, by how much, and what the money currently pays for.

The budget proposes cutting the EPA's Drinking Water State Revolving Fund by $970 million, or 87 percent, to $150 million. The Clean Water State Revolving Fund would lose $1.48 billion, a cut of 90 percent. ¹

These funds flow from EPA to state agencies like the Illinois EPA, which distributes them as low-interest loans and grants to municipal water and sewer systems. Illinois's share of the drinking water fund would fall from $54.9 million to $4.1 million. The clean water share drops from $67.6 million to $6.8 million. Combined, that is $111.7 million less in one state's pipeline alone. ²

The budget's rationale is direct: states should be responsible for funding their own water infrastructure projects. The projected taxpayer savings: over $2.5 billion. ¹

At the 2024 Republican National Convention, the president said the administration would redirect money for "important projects like roads, bridges, dams." ¹⁵ The budget does not redirect water infrastructure money. It eliminates most of it.

The budget eliminates the Community Development Block Grant program entirely, cutting $3.3 billion. ⁴ CDBG funds flow through HUD to states and then to smaller municipalities for infrastructure, downtown rehabilitation, and housing. The HOME Investment Partnerships Program, another $1.3 billion housing program, would also be eliminated.

The Community Services Block Grant, at $775 million, is eliminated as well. ⁵ In McHenry County, Illinois, the housing authority reported that 1,880 people received CSBG-funded assistance last year, including rent help, security deposit aid, emergency dental care, and job training referrals. That is one county. Every state has them.

The USDA's Community Facilities Grant earmarks, $659 million, are also cut. The budget's own description notes these have been used for "important community facilities, such as ambulances and fire stations." ¹

The administration frames the elimination of these programs as returning responsibilities to local government. The programs being eliminated are the ones local governments used to meet those responsibilities.

Selected programs, current annual funding levels

White House FY2027 Budget Request

Several major household programs are not directly cut in this budget. The Housing Choice Voucher program, SNAP, and the federal Medicaid matching rate are all maintained in the released documents, though each faces separate congressional action.

For these programs, the immediate risk is not in this document. It is in the reconciliation fights that follow, where Medicaid and SNAP are expected to be on the table. OMB's opening message signals the direction: it boasts that prior legislation "put the Medicaid program on a more sustainable path" and "returned accountability to the Supplemental Nutrition Assistance Program," tying both to the defense investment. ¹

On Medicaid specifically, the president said after the election: "We're not going to touch it. Now, we are going to look for fraud." ¹⁶ The budget tells a different story.

Not everything is being cut. Title I education funding, the largest federal K-12 program at $18.4 billion, is maintained. IDEA special education increases by $539 million. ¹⁰ Core federal highway formula funding is not reduced. Community health centers receive a modest increase.

Smaller K-12 programs are another matter. Seventeen programs worth $6.5 billion would be consolidated into a new block grant, and 12 others worth $2.1 billion eliminated. ¹⁰

At the Department of Justice, nearly 30 state and local grant programs would be eliminated, a $1.7 billion reduction. FEMA non-disaster grants are cut by $1.3 billion. ¹¹

The headline defense number requires unpacking. The $1.5 trillion figure represents all national defense resources, an all-in budget concept that includes mandatory and reconciliation funding. The base Pentagon discretionary budget is $1.1 trillion. The rest includes $350 billion in mandatory accounts, $45.6 billion for nuclear weapons programs at the Department of Energy, and smaller defense-related items. ^18,19

At the proposed level, the United States would spend more than the next 10 countries combined. By SIPRI's latest data, US military spending in 2024 was $997 billion, slightly less than the next 10 combined. At $1.5 trillion, it would account for roughly 55 percent of all global military spending and represent about 4.4 percent of GDP, up from 3.4 percent today and comparable to the late Iraq and Afghanistan war years. ^19,20

The budget funds 41 new ships across government agencies, including a proposed "Trump-class battleship." It stands up a "Golden Dome" homeland missile defense system at $18.2 billion in its first year, with no published lifecycle cost. It accelerates nuclear weapon modernization across ICBMs, submarines, bombers, and warheads. And it funds military pay raises of 5 to 7 percent, tilted toward junior enlisted ranks. ^12,28,29,30

Whether the money can be spent as planned is another question. GAO found that despite a near-doubling of the Navy's shipbuilding budget over two decades, the Navy has not increased its number of ships. New vessels have been delayed, cost more, and delivered less capability than promised. The White House's own maritime page states that the country "does not have the capacity necessary to scale up the domestic shipbuilding industry to the rate required to meet national priorities." ^14,31,32

Golden Dome's most ambitious element is space-based interceptors for boost-phase missile defense, which the National Academies have studied as a question of "feasibility, practicality, and affordability" rather than a solved engineering problem. The executive order creating the program required the Secretary of Defense to first submit an architecture and implementation plan, a sign the design was not settled when the order was signed. ²⁸

Nuclear modernization is the strongest case for spending that matches a documented threat. The US is replacing nearly every component of its strategic arsenal: the Sentinel ICBM, Columbia-class submarine, B-21 bomber, and multiple warhead programs. Every administration since Obama has supported the effort. The estimated lifecycle cost is $1.5 trillion. The Sentinel program alone has breached its Nunn-McCurdy cost cap, a statutory threshold that triggers mandatory congressional review when a weapons program exceeds its original budget by 25 percent or more, at $141 billion. ³⁰

The budget describes its threats in broad terms: "peer and near-peer adversaries," "rogue states," "contested waters," "the most catastrophic threat facing the United States." The language is deliberately general. Some of those threats are real and independent of US policy. China has built military outposts across the South China Sea, a buildup that predates the current trade war by years and that satellite imagery confirms has been underway since at least 2014. Russia invaded Ukraine, and the war continues regardless of US posture. ^1,24,25

Iran is different. Before the US withdrew from the nuclear deal in 2018, the IAEA confirmed Iran was complying with the agreement's enrichment limits. The administration withdrew and reimposed sanctions. Iran initially tried to preserve the deal with the remaining parties, then began breaching its limits: exceeding the enrichment cap in July 2019, then moving to 20 percent enrichment by 2021. The escalation continued through this year's US-Iran war and the effective closure of the Strait of Hormuz, a chokepoint for 20 percent of global oil. ^21,22,23

The Hormuz crisis is now part of the threat environment cited to justify the largest defense budget since World War II. The chain runs from a policy choice to a crisis to a budget justification. The administration did not invent Iranian hostility. But it converted a monitored, constrained nuclear program into the more volatile situation it is now asking taxpayers to fund a response to.

The border appears throughout the budget as a security priority, but border control is institutionally a Department of Homeland Security and Customs and Border Protection mission, not a Pentagon one. The FBI's national crime reporting system does not track offender nativity or citizenship, which means claims about immigrant crime rates cannot be verified from federal data. The best national comparison, from the National Bureau of Economic Research, finds that immigrants have been incarcerated at lower rates than the US-born for 150 years and are currently 60 percent less likely to be incarcerated. ^26,27

The pain should be borne by Washington bureaucrats, not by hardworking American families.

2024 campaign, Agenda47

The defense increase is larger than the entire $73 billion in domestic spending cuts. The campaign promised a stronger military. It did not promise to pay for it by cutting water infrastructure, housing grants, community services, and rural facility funding. That tradeoff is in the budget, not on the platform.

The proposal now enters a months-long negotiation with Congress. Many of the programs targeted here have bipartisan defenders. The administration's own fact sheets describe these as priorities, not accomplished cuts. But the document establishes a clear set of values: defense at historic levels, domestic programs treated as expendable, and a threat environment that, in at least one major case, traces back to the administration's own policy choices.
