Pentagon Burned Through $5.6 Billion in Munitions Within 48 Hours of Iran Strikes

The United States burned through $5.6 billion worth of munitions in the first 48 hours of military operations against Iran, a figure presented to Congress that has ignited an urgent debate over whether America's most advanced weapons stockpiles can sustain a prolonged campaign.

The Washington Post, citing three U.S. officials, reported the staggering expenditure rate as Pentagon officials separately told Congress that the first full week of operations cost roughly $6 billion, with approximately $4 billion of that spent on munitions and advanced missile interceptors used to shoot down Iranian projectiles. The two figures are not necessarily contradictory: the $5.6 billion reflects the intense opening salvo, while the slower weekly burn rate suggests the pace of high-end weapon use moderated after the initial assault.

U.S. forces have fired hundreds of precision weapons since hostilities began February 28, including advanced air defense interceptors and Tomahawk cruise missiles. U.S. Central Command reported that more than 5,000 targets inside Iran have been struck using more than 2,000 munitions. The sheer cost per strike in the opening days reflects the premium price of America's most sophisticated long-range weapons, many of which exist in limited supply.

The expenditure figures landed on Capitol Hill with considerable force. Officials described concerns about the rapid depletion of a "scarce supply of America's most advanced weaponry," a characterization that directly challenges administration assurances. Pentagon spokesman Sean Parnell pushed back, saying the department has "everything it needs to execute any mission at the time and place of the President's choosing and on any timeline."

The Pentagon is now signaling a tactical adjustment. As operations move deeper inland, U.S. and Israeli forces are pivoting toward cheaper, more plentiful laser-guided bombs rather than longer-range precision munitions. Mark Cancian of the Center for Strategic and International Studies said the shift will dramatically change the economics of the campaign: "The shift away from these longer-range munitions will dramatically lower the price of each strike, from millions of dollars spent on each round fired to less than $100,000, in some cases."

That pivot may ease the per-strike cost, but it does not resolve the broader funding crisis taking shape in Washington. The White House is expected to submit a supplemental defense budget request this week to replenish depleted stockpiles and sustain ongoing operations; the request could reach tens of billions of dollars. The request will arrive as congressional skepticism about the administration's readiness claims is already sharpening.

President Trump, meanwhile, warned Tehran against interfering with oil shipments, saying any disruption to the flow of oil through the Strait of Hormuz would trigger a retaliatory strike twenty times harder.

The financial reckoning now facing Congress reflects a fundamental tension in modern high-intensity warfare: the weapons systems that deliver the most decisive results in the opening hours of a conflict are precisely those that are hardest and most expensive to replace. At $5.6 billion in 48 hours, the United States is spending at a rate that no supplemental appropriation can easily absorb, and the stockpile math will grow more complicated the longer the campaign continues.
