The United States exhausted its entire stock of new Precision Strike Missile (PrSM) with a range of 500 km at the very beginning of the war against iran last month. However, new batches are reportedly expected to arrive soon to replenish the arsenal.
As Aviation Week reports, U.S. Army representatives confirmed this. It is noted that such use effectively served as combat testing, meaning further tests within the program may no longer be necessary.

From Defense Express, we note that although complete depletion of stocks may sound unreasonable and excessive, especially for a first deployment, it actually makes sense. First of all, because the americans had very few of these new missiles.
Serial production has only just begun. In 2024, 130 units were ordered, and another 250 in 2025. At the same time, it is unknown how many had entered service by the start of the war with iran, so expending them was not that difficult.

It is also important that this effectively became real combat testing for the new ballistic missile. Accordingly, valuable data on its use was obtained, and potential shortcomings that need to be addressed may have been identified.
It should be recalled that the PrSM is being developed as a replacement for ATACMS. Its main advantage is the increased range — currently up to 500 km, and up to 800–1000 kmin future iterations. At the same time, the warhead is reduced to 91 kg, which is intended to be compensated by extremely high accuracy.

Overall, the goal is to reach production volumes of 400 units per year by 2026 and then increase this number fourfold. Therefore, with sufficient orders and valuable operational experience gained for the new system, large-scale use will not be such a major issue.
It should also be recalled that the United States has spent a significant amount of weapons and ammunition during the war with iran. This includes both defensive systems, such as PAC-3 MSE missiles, and offensive ones, such as Tomahawk cruise missiles.
