The Pentagon’s next shopping list is so big that even a senator who votes on defense spending is calling it a reality check moment. The question is not just how much the Trump administration wants, but what it says about priorities as lawmakers get pulled into a second, separate fight over war costs.
What You Should Know
Sen. Mark Kelly said the Trump administration’s fiscal year 2027 defense budget request totals $1.5 trillion, a proposed 42% jump from 2026 levels. He criticized the plan’s scale and questioned whether projects like a space-based missile defense system are workable.
Kelly, an Arizona Democrat on the Senate Armed Services Committee, made his case on CBS’s “Face the Nation” as the administration’s budget request heads into the usual congressional grinder of hearings, markups, and deal-making.
Kelly vs the Pentagon Number
The administration’s fiscal year 2027 proposal is a starting bid, not a final law, but the size of the request sets the tone for everything that follows. According to CBS News, the plan would represent a 42% increase from 2026 defense spending levels.
Kelly’s basic argument is that the number has outrun the moment. “They need to submit a defense budget that makes sense for the moment we’re in,” he said, pointing to how quickly the topline has grown since he arrived in the Senate.
He also framed the request as a global outlier, not just a domestic sticker shock. Kelly said the defense budget was just over $700 billion when he entered the Senate and that the new request is roughly double that, pushing close to what the rest of the world spends combined.
Golden Dome, War Costs, and a Second Fight Over Math
Some items in the proposal are designed to be politically durable, including a pay raise for troops and funding to resupply munitions. Kelly’s sharper skepticism fell on the flashier projects, including a space-based missile defense concept described as a “Golden Dome” system.
Kelly warned that the idea could turn into an expensive physics lesson. “The physics on that stuff is really, really hard. I’m very confident we’re going to spend a lot of money, we’re going to get a system that doesn’t work,” he said.
Hovering over the whole budget debate is a second bill that could scramble the numbers: a supplemental request tied to the war with Iran. CBS News reported that a Pentagon official testified the war had cost about $25 billion, while U.S. officials familiar with internal assessments suggested the price tag could be closer to $50 billion.
Munitions, Leverage, and the Next Vote
Kelly also tied the budget fight to immediate readiness, saying Pentagon briefings raised alarms about how far the U.S. has drawn down certain munitions stockpiles during the Iran conflict. For Congress, that is where abstract trillions turn into a leverage question: what gets funded first, what slips, and who owns the risk if deterrence frays elsewhere.
The administration still has to sell its plan to lawmakers who can rewrite it line by line, and Kelly sits in the room where that rewriting starts. The next tell will be whether the “Golden Dome” stays a marquee item, or becomes the budget’s easiest target when the supplemental war bill lands.
