The Alarming Depletion Report
On August 4, 2026, Reuters published a bombshell report citing internal U.S. military data: the Army has used up virtually its entire stockpile of highly accurate long-range precision missiles during America’s ongoing five-month war with Iran. The revelation has triggered urgent efforts across the Pentagon to ramp up domestic missile production and has ignited a fierce debate about American military readiness.
The report specifically identified two critical missile systems as being nearly exhausted: the Army Tactical Missile System (ATACMS) and the newer Precision Strike Missile (PrSM). These weapons represent the Army’s premier long-range precision strike capability, designed to destroy high-value targets hundreds of miles behind enemy lines without risking pilots or aircraft.
The White House immediately pushed back. President Trump issued a statement claiming, “We have far more munitions than anyone in the world, and far more than we need,” and blamed the Biden administration for giving away stockpiles to Ukraine. However, the Reuters report — backed by sources familiar with classified military data — painted a starkly different picture.
Which Missiles Are Affected
The depletion extends across multiple missile families, creating a comprehensive crisis in U.S. precision strike and missile defense capabilities:
Army Long-Range Strike:
- ATACMS (Army Tactical Missile System): Virtually depleted
- PrSM (Precision Strike Missile): Virtually depleted
- GMLRS (Guided Multiple Launch Rocket System): Significantly reduced
Missile Defense Interceptors:
- Patriot Missiles: Approximately 65% of stockpile expended (per CSIS estimates)
- THAAD Interceptors: At least 38% reduction since conflict began
- Tomahawk Cruise Missiles: Significantly reduced
The distinction between strike missiles and interceptors is critical. ATACMS and PrSM are offensive weapons used to hit Iranian command posts, air defense sites, and logistics hubs. Patriot and THAAD are defensive systems that protect U.S. bases and allied territory from Iranian ballistic missiles and drones. Both categories have been consumed at rates far exceeding Pentagon projections.
The Scale of Combat Expenditure
The intensity of the Iran conflict has far exceeded what military planners anticipated. Since hostilities began on February 28, 2026, Iranian forces have launched thousands of ballistic missiles, cruise missiles, and one-way attack drones against U.S. bases across the Persian Gulf, as well as against allied nations including Saudi Arabia, Kuwait, Bahrain, and the United Arab Emirates.
Each Iranian barrage requires a defensive response. Patriot batteries typically fire two interceptors per incoming missile to ensure a high probability of kill. With Iran launching salvos of 50-100 missiles at a time, a single attack can consume 100-200 Patriot interceptors. Over five months of sustained combat, this math becomes devastating.
On the offensive side, ATACMS and PrSM have been used to strike Iranian nuclear facilities, IRGC command centers, missile storage sites, and coastal defense batteries. The U.S. has also expended significant numbers of Tomahawk cruise missiles, launched from Navy destroyers and submarines operating in the Persian Gulf and Arabian Sea.
Missile Expenditure Estimates:
Table
| Missile System | Pre-War Stockpile | Estimated Remaining | Usage Rate |
| ATACMS | Classified | <10% | Critical |
| PrSM | Classified | <10% | Critical |
| Patriot | Classified | ~35% | High |
| THAAD | Classified | ~62% | Moderate-High |
| Tomahawk | Classified | Reduced | High |
Pentagon’s Emergency Response
The Pentagon has launched an unprecedented industrial mobilization to address the shortage. The centerpiece is a record-breaking $58.6 billion contract awarded to Lockheed Martin for Patriot interceptor missile production — one of the largest single defense contracts in U.S. history.
Defense Secretary Pete Hegseth dismissed concerns about stockpile depletion as “foolish,” insisting that “America’s military is the most powerful in the world and has everything it needs to execute at the time and place of the President’s choosing.” Chief Pentagon spokesman Sean Parnell echoed this sentiment, stating that the U.S. possesses a “deep arsenal of capabilities.”
However, behind the public reassurances, the Pentagon is scrambling. The Army has cut helicopter procurement programs to redirect funding toward missile production. The “Amazon for War” initiative — a new digital logistics platform — has been accelerated to streamline munitions distribution. And defense contractors are being pressured to expand production lines at “record levels,” according to President Trump’s statement.
Strategic Vulnerabilities Exposed
Independent analysts warn that the depleted stockpile leaves the United States dangerously exposed if a second major conflict erupts simultaneously. The scenario that keeps Pentagon planners awake at night is a two-front war: continuing operations against Iran while facing a crisis with China in the Indo-Pacific or Russia in Europe.
Military planners consider ATACMS and PrSM particularly valuable against heavily defended adversaries because they can destroy command posts, air defenses, and logistics hubs from beyond enemy air-defense envelopes. Without these weapons, the Army would be forced to rely more heavily on manned aircraft, exposing pilots to greater risk and potentially increasing casualties.
The situation has exposed a long-known vulnerability in America’s “just-in-time” munitions strategy, which prioritized precision over mass. For decades, the Pentagon assumed that future wars would be short, decisive conflicts where a limited number of smart weapons would achieve rapid victory. The Iran war has shattered that assumption, demonstrating that prolonged high-intensity conflicts against major powers can exhaust even the world’s largest arsenal in months.
Production Bottlenecks and Industrial Base
Replenishing these stockpiles will take years, not months. ATACMS production lines, which were scaled back after the Cold War, cannot simply be flipped back on. Each missile contains hundreds of precision components, many sourced from a dwindling domestic supplier base.
The PrSM program is even more constrained. As a newer system, it has a smaller production footprint and relies on advanced guidance systems and propulsion technologies that only a handful of contractors can manufacture. The Army had planned to field PrSM in incrementally larger numbers through the late 2020s; the Iran war has consumed years of planned production in five months.
Manufacturing Challenges:
- 155mm artillery ammunition: Production remains hampered by quality control issues and material shortages
- Jet engines: Manufacturing delays and supply chain disruptions continue
- Semiconductor components: Critical chips for missile guidance systems face global shortage
- Skilled labor: The defense industrial base lacks sufficient engineers and technicians
Political Fallout and Public Opinion
The missile depletion report comes at a politically sensitive moment. A recent Reuters/Ipsos poll found that only one in three Americans supports the Iran war, with 69% believing President Trump has not clearly explained the goals of U.S. military involvement.
House Oversight Democrats are now seeking records behind Pentagon changes to the Iran war casualty database, suggesting the administration may be downplaying the true costs of the conflict. The missile shortage gives Congressional critics powerful ammunition to argue that the war is unsustainable.

What Happens Next
The Pentagon faces a critical decision: continue expending its remaining precision munitions in the Iran conflict, or conserve stocks for potential future contingencies. With the war now in its sixth month and no clear diplomatic resolution in sight, this tension will only intensify.
The $58.6 billion Lockheed Martin contract represents a long-term bet on rebuilding America’s missile defense industrial base, but those missiles won’t arrive for years. In the meantime, the U.S. military must navigate an increasingly dangerous world with a depleted arsenal — a reality that could reshape American strategy for the remainder of the decade.
Frequently Asked Questions
Q: Which specific missiles has the U.S. depleted in the Iran war?
A: According to Reuters, the Army has used virtually all of its ATACMS and PrSM missiles. CSIS estimates also show approximately 65% of Patriot interceptors and 38% of THAAD interceptors have been expended.
