Aviation Week: U.S. Army Unit Expended All New PrSM Missiles at Start of War with Iran

A U.S. Army unit ran out of its entire supply of the newest Precision Strike Missile (PrSM) ballistic missiles within the first weeks of fighting against Iran.

Aviation Week reported this, citing a U.S. Army official.

According to the outlet, the unit was an artillery formation involved in combat operations last month that launched these missiles using HIMARS multiple rocket systems.

This marked the first combat use of PrSM missiles. At the same time, the new system was still in testing. Military officials said that stocks of these long-range missiles would be replenished soon.

PrSM missiles are expected to gradually replace the ATACMS tactical ballistic missiles, which are being phased out of service in the U.S. Army.

Last fall, Lockheed Martin announced plans to produce 400 Precision Strike Missile (PrSM) ballistic missiles annually.

To increase output, the company is using automated manufacturing processes and advanced technology–based automated quality control.

PrSM Program

In July 2025, the PrSM program entered Phase C, which covers the start of large-scale production and the deployment of the new missiles to operational units.

At the end of March, the Pentagon signed a $4.9 billion contract to deliver a large batch of PrSM missiles in the baseline Increment 1 configuration.

Procurement of the latest ballistic missiles is planned for the period from 2025 to 2029. Under the agreement, the U.S. Army plans to receive 1,296 PrSM missiles.

In addition to procuring Increment 1 missiles, which are capable of striking only stationary targets, the U.S. military has also ordered 10 PrSM Increment 2 missiles equipped with a seeker to engage moving targets.

The PrSM missile has demonstrated the ability to hit targets at distances of up to 500 km, with an estimated range of 650 km. This significantly exceeds the capabilities of ATACMS missiles.
