The $158m contract seeks to expedite the Army’s missile fielding process.
The deal comes soon after a manufacturing readiness assessment by the Army.
At present, Lockheed Martin is focused on developing PrSMs to meet the requirements of the Army’s initial production and engineering and manufacturing development (EMD) contracts, awarded in September last year.
The company is also working on producing additional rounds for system qualification tests, which are scheduled to be held in 2023.
The decision on the full-rate production of the qualified system is expected to be finalised in 2025.
The PrSM is an advanced version of the Army Tactical Missile System (ATACMS) missiles.
The low-risk, long-range, surface-to-surface missile enables the Army to neutralise and destroy targets through indirect fire.
The ballistic missile features an open system architecture, enabling future technological enhancements and growth capabilities for follow-on spirals.
As the key designer and manufacturer of long-range precision strike solutions, Lockheed Martin Missiles and Fire Control has delivered several systems including multiple launch rocket system (MLRS), high mobility artillery rocket system, and ATACMS to customers worldwide.
Earlier this year, Lockheed Martin delivered the first MLRS M270A2 launcher to the US Army.
The upgraded version of the mobile rocket launching system will make the M270A2 compatible with munitions, including the extended-range GMLRS and PrSM.
