The Precision Strike Missile (PrSM) is a short-range ballistic missile developed by the United States Army to replace the MGM-140 ATACMS.

In March 2016, Lockheed Martin, Boeing, and Raytheon announced they would bid on a missile to meet the U.S. Army's Long Range Precision Fires (LRPF) requirement to replace the ATACMS. The PrSM will use advanced propulsion technology to fly faster and farther (originally out to 499 km (310 mi)).^[2] It is also designed to be thinner and sleeker, increasing the number of missiles per pod to two, and doubling the capacity of the M270 MLRS and M142 HIMARS launchers.^[3][4] Boeing and Raytheon were involved in the competitive effort, but both left the competition in early 2020, leaving Lockheed Martin to develop the missile.^[5] The weapon is planned to achieve initial operational capability in 2023; the initial PrSM will only be able to hit stationary targets on land, but later versions will track moving targets on land and sea.^[6] With the United States withdrawal from the Intermediate-Range Nuclear Forces Treaty, the range of the PrSM will be increased beyond the 499 km (310 mi) limitation imposed by the treaty.^[7]

In June 2020, the Army had begun testing a new multi-mode seeker – an upgrade for the Precision Strike Missile – even though the missile would not enter service until 2023, the upgraded seeker is expected to be part of a major program improvement planned for 2025.^[8]

Technological advancements including the potential application of ramjet technology could extend the weapon's range up to 1,000 km (620 mi).^[9]

In July 2021, the US announced that Australia had become a partner in the PrSM Program with the Australian Army signing a memorandum of understanding for Increment 2 of the program with the US Army's Defense Exports and Cooperation and had contributed US$54 million.^[10][11]

The United Kingdom, as part of an upgrade to the British Army’s M270 MLRS to the M270A2 standard, has hinted that it may possibly acquire PrSM.^[12]

On December 8, 2023, the US Army announced that the first PrSM batch has been delivered.^[13]
