President Donald Trump unveiled his fiscal year 2027 budget proposal Friday, requesting an unprecedented $1.5 trillion in defense spending — a 42% increase — while cutting nondefense spending by $73 billion, or 10% .

The White House released the 92-page budget request on Friday, accompanied by several summaries of the administration’s key priorities across the executive branch . The proposal represents the largest defense spending request in modern history and immediately triggered a fierce partisan battle on Capitol Hill over national priorities.

If passed, it would mark the first time the base budget defense spending has hit the $1 trillion mark— representing a 28 percent increase from the FY26 base budget . With the addition of reconciliation spending, which will need to be passed by Congress this year, the FY27 budget hits a historic high, representing a 44 percent boost to the defense budget .

The administration plans to split the defense funding into two tracks: $1.15 trillion through its annual appropriations process and enact the remaining $350 billion through a legislative tactic known as reconciliation, which allows Republicans to bypass the need for Democratic votes in the Senate .

Republican defense leaders welcomed the massive increase. “This bold commitment provides the resources needed to rebuild American military capability and confront those challenges head-on,” Rep. Mike Rogers of Alabama and Sen. Roger Wicker of Mississippi said in a joint statement . They noted that the proposed funding will drive the U.S. toward a defense budget that makes up 5% of the nation’s gross domestic product — a benchmark spending level that the U.S. has demanded of its NATO allies .

“America is facing the most dangerous global environment since World War II,” said Sen. Roger Wicker, R-Miss., and Rep. Mike Rogers, R-Ala .

Democrats launched a coordinated assault on the proposal. “The vision President Trump has outlined for America in his budget is bleak and unacceptable. President Trump wants to slash medical research to fund costly foreign wars. It doesn’t get more backward than that, and the only responsible thing to do with a budget this morally bankrupt is to toss it in the trash,” said Senator Patty Murray, Vice Chair of the Senate Appropriations Committee .

Sen. Patty Murray, of Washington, the top Democrat on the Senate Appropriations Committee, also denounced the proposed budget, describing it as “morally bankrupt,” and said she would ensure Congress wrote a new one instead. “Trump wants to build a ballroom,” Murray said, referring to the White House renovation . “I want to build more affordable housing, and only one of us sits on the Appropriations Committee” .

“This is not a serious budget,” said Sen. Jack Reed of Rhode Island, the top Democrat on the Senate Armed Services Committee. “From what little information we have, this flawed, irresponsible proposal is unjustified and fails to acknowledge the negative impacts of Trump’s Iran war and faltering economy.” He said he would not rubber stamp a “bloated, undisciplined budget” and said the Pentagon lacked responsible leadership and management, not funding .

The top Democrat on House Budget Committee, Rep. Brendan Boyle of Pennsylvania, said the president was demanding a massive increase in defense while cutting billions from health care, housing and more. “This budget represents ‘America Last,’” Boyle said .

The defense increases come as the U.S. is spending billions of dollars for the war in Iran, and the White House is preparing to ask Congress for a supplemental spending package to cover the cost of the conflict . The massive military buildup includes funding for Trump’s “Golden Fleet” as waters around the world become more contested, according to a fact sheet provided by the White House .

Specific military investments include 85 F-35 Joint Strike Fighter jets, which includes a total of 38 F-35A conventional takeoff and landing variants, 10 F-35B short takeoff and vertical landing jets, and 37 F-35C carrier variant planes. Only 32 are slated to be paid for through the base budget, with the remaining 53 covered by reconciliation funds .

The proposal also includes military pay raises, with a 7% pay boost for the most junior enlisted ranks, a 6% pay raise for midlevel enlisted troops and junior officers and a 5% pay increase for all higher officer ranks .

To offset the defense increases, the Trump administration is proposing a 10% cut to nondefense discretionary spending — a $73 billion reduction . “Savings are achieved by reducing or eliminating woke, weaponized and wasteful programs, and by returning State and local responsibilities to their respective governments,” a White House fact sheet says .
