US used many weapons in 38-day war with Iran
US used many weapons in 38-day war with Iran
Introduction
The US military used a lot of advanced weapons in a 38-day war with Iran. The war started on February 28 and then stopped. Now, the US has fewer weapons. This could be a problem for other places, like the Indo-Pacific.
Main Body
The US used about 1,100 long-range missiles called JASSM-ER. Each missile costs about $1.1 million. Now only about 1,500 remain. They also used more than 1,000 Tomahawk cruise missiles. Each Tomahawk costs about $3.6 million. That is ten times more than they make in one year. The US also used over 1,200 Patriot interceptor missiles. Each costs more than $4 million. They used more than 1,000 Precision Strike and ATACMS ground missiles. A study says the US now has about 3,000 Tomahawk missiles. That is not enough for a big war in the Western Pacific. The US made about 600 Patriot interceptors in 2025. But they used more than double that number. The war cost between $28 billion and $35 billion. In the first 48 hours, they spent $5.6 billion. Because the US used so many weapons, they had to move weapons and people from other places. In Europe, they lost drones. This is a problem for NATO. In Asia, they moved a carrier group and 4,400 Marines from the Pacific. They also moved interceptor missiles from South Korea. These missiles were for North Korea. Now they are in the Middle East. A US general said there are limits to the number of weapons. But he said it did not hurt the US ability to stop China. The White House press secretary said the story is false. She said the US military has enough weapons. A Pentagon spokesperson did not talk about specific needs. But analysts and some lawmakers are worried. It will take years to make new weapons. A retired Marine colonel said some weapons were short before the war and are even shorter now. A report said the US is now more vulnerable in the western Pacific. The Pentagon has not started making more weapons yet. They made agreements with companies in January to make four times more weapons. But they need money from Congress. That money is not approved yet. The war also cost extra money for destroyed aircraft: two MC-130 planes and three MH-6 helicopters, about $275 million. Also, gas prices went up because the war threatened the Strait of Hormuz. That is where 20% of the world''s oil passes every day.
Conclusion
The US war with Iran used many advanced weapons, especially long-range missiles and air-defense missiles. The White House says there are enough weapons. But analysts and internal reports say it could take years to make new weapons. This could make the US less ready for other wars, especially in the Indo-Pacific. The Pentagon is waiting for money from Congress to start making more weapons. If there is another war with Iran, it will be even harder.

US weapons stockpiles heavily used after 38-day campaign against Iran, raising concerns about readiness in other regions
Introduction
The United States military used large amounts of advanced weapons during its 38-day campaign against Iran, which started on February 28 and was followed by a ceasefire. Internal Pentagon estimates and congressional sources indicate that supplies of several important missile systems have been reduced to levels that may affect the military''s ability to respond to possible conflicts in other areas, especially the Indo-Pacific.
Main Body
According to internal Defense Department estimates and congressional officials cited in multiple reports, the US used about 1,100 Joint Air-to-Surface Standoff Missile-Extended Range (JASSM-ER) stealth cruise missiles, each costing roughly $1.1 million, leaving an estimated 1,500 remaining. More than 1,000 Tomahawk cruise missiles, priced at about $3.6 million each, were also fired—about ten times the yearly production rate. The Pentagon deployed over 1,200 Patriot interceptor missiles, each costing more than $4 million, and more than 1,000 Precision Strike and ATACMS ground-based missiles. A study by the Center for Strategic and International Studies (CSIS) estimated that the Tomahawk stockpile now stands at around 3,000 missiles, a level considered not enough for a major conflict in the Western Pacific. The strain on air-defense systems is especially serious: the US produced roughly 600 Patriot interceptors in all of 2025, yet used more than double that number in the campaign. The overall financial cost of the conflict has been estimated by two independent groups—the American Enterprise Institute and CSIS—at between $28 billion and $35 billion, with $5.6 billion used in the first 48 hours alone. As a result of the depletion of weapons, the Pentagon has been forced to move weapons and personnel from other regional commands. In Europe, the loss of surveillance and attack drones has been described as a serious problem, affecting NATO''s eastern flank and the ability to deter Russian aggression. Furthermore, in Asia, the USS Abraham Lincoln carrier strike group was sent from the South China Sea to the Middle East before the conflict began, and two Marine Expeditionary Units totaling about 4,400 personnel were moved from the Pacific. For the first time, interceptor missiles from the Terminal High Altitude Area Defence (THAAD) system stationed in South Korea—originally deployed to counter North Korean missile threats—have been redirected to the Middle East. Admiral Samuel Paparo, head of US Indo-Pacific Command, admitted during a Senate hearing that “there are limited supplies” but stated that ongoing operations have not imposed a real cost on deterrence against China. White House Press Secretary Karoline Leavitt said the claims of shortfalls were false, stating that “the entire premise of this story is false” and that the US military remains “fully loaded with more than enough weapons and munitions.” Pentagon spokesperson Sean Parnell declined to comment on specific theater requirements, citing operational security. However, analysts and some lawmakers have expressed concern about the time needed to rebuild stockpiles. Senator Jack Reed (D-RI) noted that “at current production rates, rebuilding what we have used could take years.” Retired Marine Corps Colonel Mark Cancian of CSIS observed that “some critical ground-attack and missile-defense weapons were short before the war and are even shorter now.” A CSIS report warned that high expenditure rates have created “a window of increased risk in the western Pacific.” The Pentagon has not yet started expanded production, despite having secured seven-year agreements in January with major defense contractors such as Lockheed Martin to quadruple output of precision-guided munitions and THAAD interceptors. Officials stated that no expanded production has begun because the funding—reportedly a $200 billion supplemental appropriations request—is still awaiting congressional approval. Separately, the conflict has also caused unexpected costs from destroyed aircraft, including two MC-130 cargo planes and three MH-6 helicopters, estimated at about $275 million. Broader economic effects include a rapid increase in US gasoline prices as the conflict threatened the Strait of Hormuz, through which about 20% of the world''s daily oil supply passes.
Conclusion
The US military campaign against Iran has resulted in a significant reduction of advanced weapons, especially long-range strike missiles and air-defense interceptors. While the White House maintains that stockpiles remain sufficient for all operational needs, independent analysts and internal estimates indicate that rebuilding supplies to pre-war levels could take years, possibly creating a period of reduced readiness in other strategic regions, particularly the Indo-Pacific. The Pentagon is waiting for congressional funding to start expanded production, and the duration of any future conflict or renewed operations against Iran would further affect the balance between immediate needs and long-term ability to prevent conflict.

US munitions stockpiles significantly depleted after 38-day campaign against Iran, raising concerns about readiness in other theatres
Introduction
The United States military has expended substantial quantities of advanced munitions during its 38-day campaign against Iran, which commenced on February 28 and was followed by a ceasefire. Internal Pentagon estimates and congressional sources indicate that inventories of several critical missile systems have been reduced to levels that may affect the military''s ability to respond to potential conflicts in other regions, particularly the Indo-Pacific.
