US President Donald Trump has asked lawmakers to approve a massive $1.5tn defence budget for 2027, as the United States faces rising costs from its war with Iran and mounting global security commitments.
The 2027 budget request comes as the president faces risky choices abroad, with the administration sending US service members to the Middle East, and a weary public at home feeling the economic crunch of skyrocketing gas prices due to the conflict.
The White House boasted that this defence funding approaches the "historic increases just prior to World War II”.
The hefty ask contrasts with the more sceptical view Trump took towards military spending in his first term, when he even once called the level of funding "crazy”.
Trump came into office vowing to cut federal spending and rein in the nation’s growing budget deficit, bringing in the world’s richest person Elon Musk to lead an effort that pushed about 300,000 people off the federal payroll.
The request ultimately requires approval by the US Congress, where disagreement over Trump's spending decisions recently led to the longest government shutdown in US history.
The proposal would lift Pentagon spending by more than 40% in a single year as Washington seeks to sustain military operations and rebuild depleted weapons stockpiles.
The request highlights the growing financial pressure of a conflict now in its fifth week, and sets up a political battle in Congress over how to fund a dramatic expansion of military spending.
US media – citing closed-door congressional briefings – have reported that the Iran war could be costing as much as $2bn a day, underscoring the scale of the burden even before longer-term reconstruction and resupply costs are factored in.
To offset part of the increase, Trump is proposing around $73bn in cuts to non-defence spending – roughly 10% – "reducing or eliminating woke, weaponised and wasteful programmes, and by returning State and local responsibilities to their respective governments”.
The president has framed the defence increase in urgent terms, arguing that military investment must take precedence during wartime, even at the expense of federal social programmes.
"It's not possible for us to take care of day care, Medicaid, Medicare," Trump said at a recent private event, adding that such responsibilities could be handled at the state level while Washington focuses on "military protection".
There are big cuts proposed to many major federal departments, including a 19% decrease for the US agriculture department, a 12.5% cut for the US health department, and a 52% cut for the Environmental Protection Agency.
Democrats swiftly attacked the proposal, with the party's Senate budget leader Patty Murray warning that it prioritied military spending over Americans' needs and accusing Trump of pursuing "reckless foreign wars”.
"Donald Trump might be happy to spend more money on bombs in the Middle East than on families here in America – but I am not," she said in a statement.
The White House released the request as part of a detailed 92-page budget proposal, alongside summaries outlining its priorities across federal agencies.
The plan is not binding but serves as a statement of the administration's priorities as Congress begins drafting spending legislation, with lawmakers retaining the power to rewrite or reject it.
Trump is urging Congress to approve the bulk of the defence budget – more than $1.1tn – through the standard appropriations process, while seeking to pass a further $350bn using a party-line mechanism that would bypass Democratic support.
Republican leaders have shown openness to that approach, particularly as they push for higher defence and immigration enforcement spending.
However, the plan may face resistance within Trump's own party, where some lawmakers are wary of deepening federal deficits.
The United States is already running annual shortfalls approaching $2tn, with total debt exceeding $39tn, leaving limited fiscal space for new spending without further widening the gap.
Lawmakers from both parties have also raised concerns about the scale of the proposed military increase, particularly as the administration has provided limited detail on the trajectory of the Iran conflict.
There is similar scepticism about the domestic cuts, many of which Congress has previously rejected.
Spending bills passed earlier this year largely preserved funding for programmes the White House is again seeking to reduce or eliminate.
Beyond defence, the administration is proposing increased funding for federal law enforcement, including a boost of more than $40bn for the Justice Department.
Even so, the plan could add trillions more to the federal debt over the coming decade if enacted in full, highlighting the trade-offs facing lawmakers as they weigh wartime demands against long-term fiscal pressures.
Some Republicans, however, backed the push, with congressional defence leaders saying that the increase would help move US military spending toward 5% of GDP and strengthen deterrence.
Roger Wicker and Mike Rogers, the respective chairmen of the Senate and House armed services committees, praised Trump in a joint statement for "sending a clear signal for our allies and partners to build on recent progress and meet this benchmark alongside us”.
