US military officials on Tuesday called for spending tens of billions of dollars in the next budget year on drones, air defence systems and fighter jets that have been a key part of fighting the Iran war.

As part of President Donald Trump's push to boost defence spending to $1.5 trillion in the 2027 budget, the Pentagon wants to triple spending on drones and related technology to more than $74 billion and invest over $30 billion into more critical munitions, including missile interceptors, whose stockpiles have become critically low during the Iran war.

Military officials said the spending blueprint was developed before the conflict in the Middle East. They also did not discuss how much they will request in additional funds for the war, which would be on top of what the White House is seeking to boost defense spending in the next budget year.

“The overlap, you'll see, is the request for munitions, which is something we always need," Jules Hurst III, acting undersecretary of defense and the Pentagon's comptroller, told reporters at a briefing. "We always need to increase our magazine depth. But outside of that, there aren't any operational costs in here from Iran.”

Heavy investment in drone warfare

The missile interceptors whose numbers are under the most strain are the Patriot and the Terminal High Altitude Area Defense, or THAAD, air defense systems. The THAAD system is designed for defeating medium-range ballistic missiles, while the Patriot system is for taking down short-range ballistic missiles and crewed aircraft. However, they both also were used to shoot down cheap Iranian drones.

The $30 billion budget item also would aim to purchase long-range Precision Strike Missiles and Mid-Range Capability missile systems used by the US Army.

The budget proposal would allocate nearly $54 billion for military drones and related technology, as well as $21 billion for weapons systems designed to take down enemy drones.

Drones and other unmanned vehicles have emerged as a key weapon in the wars in Ukraine and Iran, and top Pentagon officials say the US must significantly increase its funding of both drones and counter-drone systems.

“Drone warfare is rapidly reshaping the modern battlefield,” Hurst said. “This budget is the largest investment in drone warfare and counter drone technology in U.S. history.”

As part of the 2027 budget, the Pentagon also intends to grow the military by 44,500 troops, or more than 2%, spend more than $2 billion on operations on the U.S.-Mexico border and make the largest shipbuilding request since 1962.

Dramatic increase in the Navy's Tomahawk missiles

While officials said the budget was developed before operations began in Iran, it featured major jumps in many of the missiles that have been used in the conflict. One of the most dramatic increases was in the choice for the Navy to increase of its purchase of the Tomahawk cruise missile from 55 missiles last year to 785 in this year's budget.

The long-range cruise missile was heavily used in Iran and led to concerns from experts that the military was using it much faster than it could replenish its stocks.

Vice Adm. Ben Reynolds, the Navy's budget boss, wouldn't say if he expected all 785 Tomahawk missiles to be delivered within the year. He acknowledged that weapons production capacity “is absolutely the challenge” and, in the case of the Tomahawk, he said the Navy expects Raytheon — the company that makes it — “to invest very heavily now to be able to ramp up production.” The services also are addressing the difficulty in producing the advanced munitions favored by the military by slowly shifting toward more basic weapons.

Major Gen. Frank Verdugo, the Air Force's budget chief, said the Air Force wants to invest $600 million to develop “affordable” munitions as part of an effort to move away from “small numbers of exquisite weapons toward a future where we can overwhelm an adversary with sheer volume.”

Trump-endorsed battleship is missing

The Navy said it would be buying 18 more warships using more than $65 billion — a 46% increase from the previous year.

However, the Trump-endorsed battleship that was announced to great fanfare last year is not in this year's budget, according to the briefing. Instead, the Navy is planning to pay for the first battleship in next year's budget.

The military's spending proposal also lacked money for repairing US bases in the Middle East, which Hurst said would be part of a future request.

“Part of it is we would assess what our posture should be in the Middle East,” Hurst told reporters. “We have to make sure we understand what we want to construct in the future. We might change how we build bases in the Middle East based on this conflict.”

Budget echoes Biden-era priorities, expert says

If approved by Congress, the budget would provide the largest level of defense funding in inflation-adjusted dollars in US history, said Todd Harrison, a senior fellow at the American Enterprise Institute, a conservative think tank.

Harrison said the spending appears more aligned with former President Joe Biden's national defense strategy than Trump's.

“This is a budget that is trying to build a force capable of sustaining U.S. presence and security commitments around the world — a force that's capable of fighting major wars against countries like Russia and China,” Harrison said.

The Trump administration's strategy document put the priority on homeland defence and was largely silent on Russia and did not say much about China, Harrison said.
