The U.S. Department of Defense announced Tuesday that the United States has spent $29 billion [1] on the war in Iran to date.

The spending surge and the depletion of military assets raise critical questions about the long-term sustainability of the conflict and the readiness of U.S. forces.

Defense Secretary Pete Hegseth and senior Pentagon officials presented the figures during a briefing in Washington, D.C., ahead of a joint hearing of House and Senate armed-services committees. The announcement sparked questioning from Democratic and Republican lawmakers regarding the pace of expenditure and the impact on national security.

"The cost of the war has reached $29 billion," a senior Pentagon official said [1].

The financial escalation is particularly sharp. A Pentagon spokesperson said the current figure is $4 billion [2] higher than the amount reported just two weeks ago.

Beyond the fiscal cost, officials warned that the intensity of the conflict is straining the U.S. military's industrial capacity. The rapid use of munitions has created a gap in available resources needed to maintain a deterrent posture.

"We are seeing a rapid depletion of weapons stockpiles," Hegseth said.

Lawmakers expressed concern that the diminishing stockpiles could compromise the U.S. ability to respond to further escalations in the region. The briefing highlighted a growing tension between the operational requirements of the war and the logistical reality of weapon production, and replenishment.

“"The cost of the war has reached $29 billion,"”

The rapid increase in spending—averaging $2 billion per week over the last 14 days—suggests a significant escalation in the intensity of combat operations. When coupled with the depletion of munitions, this indicates that the U.S. may be reaching a logistical tipping point where the rate of consumption exceeds the rate of production, potentially forcing a strategic reassessment of the conflict's duration.
