WASHINGTON, Apri; 29 (UPI) — Secretary of Defense Pete Hegseth alternated between championing a proposed massive increase to defense spending and fielding attacks from Democratic lawmakers during testimony on Capitol Hill Wednesday.

It marked the secretary’s first appearance before lawmakers since the start of a war that has roiled the global economy and decimated Iran’s military.

Hegseth appeared before the House Armed Services Committee alongside Gen. Dan Caine, chairman of the Joint Chiefs of Staff, and the Pentagon’s comptroller, Jules Hurst III. They entered the hearing room past protesters’ chants of “arrest Hegseth” and yells of “war criminal.” The secretary appeared unfazed.

“We’re rebuilding a military that the American people can be proud of — one that instills nothing less than unrelenting fear in our adversaries.” Hegseth said in his opening statement.

Hegseth’s testimony was intended to serve as a defense of the White House’s petition to Congress for $1.5 trillion in defense spending for 2027, a 44%t increase from the 2026 budget.

It’s an increase that, by itself, would be more than the total defense spending of any other nation, according to recently released figures. The spending level exceeds that spent on the Reagan-era military buildup and would be only overshadowed by levels seen during World War II.

The spending boom would come at the cost of domestic programs and at a time when federal tax revenue is set to take a $4.5 trillion hit over the next 10 years, mostly from tax cuts codified in last year’s One Big Beautiful Bill Act, according to the Bipartisan Policy Center, a Washington-based think tank.

But rather than question Hegseth on the specifics of the budget proposal, many Democratic members grilled him about the war in Iran, recent firings of senior leaders in the Pentagon and lethal strikes against alleged drug traffickers in the Pacific and Caribbean oceans.

In one heated exchange, Rep. John Garamendi, D-Calif., delivered a sharp critique of the war in Iran when questioning the defense secretary, calling it a “blunder” in which the United States had expended much to gain little.

Garamendi said it would take years for the U.S. and global economies to recover. The war has hiked average unleaded gas prices in the country to more than $4.20 a gallon and inflation to its highest level in nearly two years.

“Secretary Hegseth, you have been lying to the American public about this war from Day 1,” Garamendi said. “The strategy has been an astounding example of incompetence.”

Hegseth counterattacked. With his voice raised, he accused the congressman of “handing propaganda to our enemies.”

“I hope you appreciate how reckless it is,” Hegseth said of Garamendi’s description of the two-month-long war as a quagmire. “Shame on you.”

Hurst, the comptroller, told lawmakers the Iran war has cost the Pentagon $25 billion. Committee ranking member Rep. Adam Smith, D-Wash., responded that was the first time he had been given a cost figure, despite repeated inquiries to the department.

In March, the Pentagon reportedly petitioned Congress for an additional $200 billion to replace stocks from the war and prepare for future operations, should they be ordered. When asked about it at the time, Hegseth indicated the report’s veracity.

“That number could move, obviously,” Hegseth said then. “It takes money to kill bad guys.”

Hegseth’s central defense of the war during the hearing was arguing that it served to prevent Iran from obtaining a nuclear weapon. Republican members echoed his contention.

Iran maintains uranium supplies that could eventually be used to build a nuclear weapon if it were to be further enriched. But since the U.S. bombed Iran’s nuclear facilities in June, Iran has made “no efforts since then to try to rebuild their enrichment capability,” Tulsi Gabbard, the director of national intelligence, said in a written statement to Congress in March.

“What is it worth to ensure Iran never gets a nuclear weapon?” Hegseth asked rhetorically in Wednesday’s hearing.

A defense budget unprecedented in modern times

The Pentagon’s budget request is composed of $1.1 trillion in base discretionary funding and an additional $350 billion in mandatory spending.

The mandatory funds, which are earmarked mostly for munitions and the expansion of the defense industry, would go through the budget reconciliation process and therefore would be shielded from a potential Democratic filibuster in the Senate.

The expansion of America’s defense industrial base — the network of private manufacturers that supply the Pentagon — is a central facet of the proposed budget.

“President Trump inherited a defense industrial base that had been hollowed out by years of ‘America Last’ policies,” Hegseth said. “Under the leadership of President Trump, our builder-in-chief, we are reversing this systemic decay and putting our defense industrial base on a war-time footing.”

Another of the administration’s top defense funding priorities, as reflected in the budget document, is the procurement of munitions.

“Critical munitions are vital to the administration’s priorities to defend the homeland and deter potential aggression after years of neglect by the previous administration,” the White House wrote in a recent budget justification. Limited munitions stockpiles and the United States’ inability to quickly produce them have long troubled U.S. war planners.

While the Trump administration has pushed to expand munitions stockpiles, it has also expended massive amounts of scarce ordnance in the Middle East in recent months.

An April analysis by the Center for Strategic and International Studies estimated that the U.S. military has expended more than 850 Tomahawk cruise missiles in the Iran war from an estimated prewar inventory of 3,100.

Key U.S. capabilities like the Patriot and THAAD air defense systems have also seen stockpiles dwindle by about half since the start of the war, according to the report.

“We’re fighting wars”

The administration’s request for the massive infusion of cash comes as Trump has said that federal spending on healthcare and social programs should take a back seat to “military protection.”

In its proposed budget, the White House moved to cut non-defense discretionary spending by 10%. The spending category comprises public health, scientific research and scores of other domestic programs, but excludes mandatory programs like Medicare and Medicaid.

In a speech at a private Easter luncheon, Trump said spending on childcare, Medicare and Medicaid should be left to the states, while the federal government should be focused solely on national defense.

“We’re fighting wars,” Trump said.

The sentiment runs contrary to Trump’s long-held foundational critique of his predecessors — that money spent on foreign wars from Iraq, to Afghanistan, to Ukraine, should have been used to benefit Americans at home.

An advanced imaging infrared seeker from a U.S.-made Terminal High Altitude Area Defense (THAAD) anti-ballistic missile interceptor looks to have been recovered largely intact in Syria. This could be a major intelligence loss that may allow adversaries to gain valuable insights into the capabilities of THAAD, which is being very heavily employed in the current conflict with Iran. THAAD has also been an important player in blunting previous Iranian missile barrages against Israel, and is a key component of the U.S. military’s global missile defense architecture.

A video, seen below, began circulating on social media earlier today showing the THAAD seeker, as well as other portions of the interceptor, on the ground. The clip is said to have been shot in the vicinity of the Syrian city of Suwayda in the southwestern corner of the country, though TWZ cannot immediately verify this independently. However, Suwayda is some 25 miles north of the border with Jordan and around 55 miles to the east of Israel’s internationally recognized boundaries. The U.S. military is currently reported to have THAAD batteries in Israel and Jordan.

As its name indicates, THAAD is designed to intercept short, medium, and intermediate-range ballistic missiles in the terminal phase of flight. Depending on a variety of factors, including the physical position of the launcher relative to the threat, the system can attempt intercepts against targets just as they begin their descent into Earth’s atmosphere.

THAAD cues its interceptors before their launch, either using its own powerful AN/TPY-2 radar or via data from offboard sensors through the Command, Control, Battle Management and Communication (C2BMC) network.

After launch, the so-called “kill vehicle” at the front end detaches from the rocket booster at the rear. A shroud at the front, which covers the seeker and the rest of the kill vehicle, also breaks away. That shroud is also seen on the ground in the newly emerged video.

Freed from the shroud, the kill vehicle uses its conformal infrared seeker to find and home in on the target missile. In general, imaging infrared has the benefit of being a passive guidance method that is immune to radiofrequency countermeasures, such as jamming or decoys designed to mimic the radar signature of a real threat.

THAAD’s interceptors are hit-to-kill types that are designed to destroy their targets through sheer force of impact. As such, the kill vehicles do not contain any kind of explosive warhead. Each one does have several small rocket motors that help it precisely maneuver into position to slam into the incoming missile. These are collectively known as the Divert and Attitude Control System (DACS).

“The unique DACS provides two kinds of propulsion: one for attitude control and another for kill-vehicle maneuvering. The DACS uses six thrusters to provide roll, pitch, and yaw control for the interceptor,” according to L3Harris, which supplies this component of the interceptor. “These thrusters work together to precisely stabilize the interceptor-seeker field of view for proper target visibility. The seeker’s target data are then converted into maneuvering or divert commands that actuate the other four DACS thrusters as required. The four divert thrusters provide short, forceful pulses to quickly and accurately position the THAAD kill vehicle for target intercept.”

In the video, the entire kill vehicle is intact enough that the ports for some of these rockets are plainly visible.

The fact that the kill vehicle and shroud were recovered on the ground so close together and in relatively good condition points to a failure of some kind, but the exact circumstances remain unknown. What has since happened to the debris is also not known.

Gaining access to a THAAD interceptor seeker, as well as the rest of the kill vehicle, would give an adversary new insights into its performance envelope and other capabilities. That information could then be used in the development of new countermeasures, as well as tactics, techniques, and procedures to reduce the interceptor’s effectiveness. This would be on top of what Iran, as well as countries like Russia and China, have already been gleaning just from observing THAAD’s performance in the current conflict, as well as prior engagements.

Deep intelligence exploitation of the physical design of the seeker and the kill vehicle, as well as the materials used to make them, could be beneficial for supporting other developments, as well. The kill vehicle and the systems within have to survive the stresses of traveling at hypersonic speeds, typically defined as anything above Mach 5, as it screams toward its target. Adversaries like China could leverage this information to improve their own anti-ballistic missile capabilities or attempt to clone THAAD more directly.

Employing highly advanced weaponry of any kind always carries at least a degree of risk of intelligence loss. Even just in the course of normal operations, the most reliable systems can still fail and fall into the wrong hands. This is not the first time TWZ has called attention to this reality, including in regard to the recovery of sensitive components of surface-to-air interceptors. The U.S. government, as well as China, Russia, and many other countries, have extensive foreign materiel exploitation programs poised to seize on any opportunity to acquire weapon systems and other equipment for extensive analysis, testing, and even reverse engineering.

Though we do not know what happened to the THAAD seeker and the rest of the kill vehicle seen in the video, this may not be the last time we see such debris in Syria or elsewhere in the region, given how extensively these interceptors are being used as Iranian ballistic missile attacks continue.

The deterrence posture against North Korea will not be hindered regardless of a potential shift of military assets owned by the U.S. military stationed in South Korea, a senior official at Cheong Wa Dae said Wednesday, amid media reports that the U.S. Forces Korea (USFK) has shipped out some of its air defense assets from the Korean Peninsula.

“Given our level of military capability, defense spending, defense industry capacity and the high morale of our troops, there is no problem with deterrence against North Korea regardless of whether some USFK assets are relocated overseas,” the official said.

The official, however, declined to comment on media reports that parts of a Terminal High Altitude Area Defense (THAAD) system and other air defense units owned by the USFK were moved from South Korea amid a raging war in the Middle East.

“It is not appropriate for our government to comment on military operations between Korea and the U.S.,” the official said.

The official said South Korea and the U.S. have remained in close coordination to maintain a robust combined defense posture.

“Korea and the U.S. will maintain a robust combined defense posture to contribute to peace and stability on the Korean Peninsula and in the region,” the official said. “To that end, the two countries will continue close communication and coordination.”
