Lockheed Martin starts building early versions of land-based PrSM precision missile with multi-mode guidance

Nov. 7, 2023
PrSM is a surface-to-surface all weather precision-strike missile fired from the M270A1 MLRS and the M142 High Mobility Artillery Rocket System (HIMARS).

REDSTONE ARSENAL, Ala. – Tactical missile designers at Lockheed Martin Corp. are moving ahead with building U.S. Army long-range Precision Strike Missile (PrSM) systems with multi-mode guidance to destroy enemy targets as far away as 300 miles.

Officials of the Army Contracting Command at Redstone Arsenal, Ala., announced a $67.5 million contract in late September to the Lockheed Martin Missiles and Fire Control segment in Grand Prairie, Texas, for PrSM early operational capability lot 3.

The PrSM, which should enter service this year, is a surface-to-surface, all weather, precision-strike guided missile fired from the M270A1 Multiple Launch Rocket System (MLRS) and the M142 High Mobility Artillery Rocket System (HIMARS).

The missile uses Global Positioning System (GPS) satellite navigation and inertial gyro navigation to reach the vicinity of its targets. Once the missile reaches its target area, it listens for radio signals from enemy radar or communications to refine its targeting, and finally uses an imaging infrared sensor to pinpoint its target before impact.

Lockheed Martin won a $23.9 million order in late 2021 for engineering and manufacturing development (EMD), and early operational capability of PrSM lot-one missiles that are in milestone B. EMD is the last developmental stage before full-scale production.

The long-range PrSM precision missile is to replace non-insensitive and cluster munition versions of the Army MGM-140 Army Tactical Missile System (ATACMS).

PrSM will provide Army and Marine Corps field artillery units with long range and deep strike capability. The PrSM will destroy, neutralize, or suppress targets at ranges from 43 to 250 miles using indirect precision fires.

The baseline missiles will be able to engage a wide variety of targets at ranges as long as 310 miles. It will emphasize imprecisely located area and point targets. Primary emphasis for follow-on upgrades will be on increased range, lethality, and ability to attack time-sensitive, moving, hardened, and fleeting targets.

By 2025 the Army will be able to use PrSM to attack and destroy moving enemy ships operating offshore at ranges out to about 310 miles. While the weapon primarily has surface-to-surface applications for use against enemy air defenses, troop fortifications, and armored vehicle columns, the PrSM guidance system is being configured with an advanced targeting multi-mode seeker to include maritime strike.

The new targeting seeker has completed a captive carry test wherein it flew aboard an aircraft against representative targets in preparation for further testing and ultimate deployment.

On this order Lockheed Martin will do the work in Grand Prairie, Texas, and should be finished by September 2026.
