MLRS Mods

The MLRS Mods program, as detailed in Line Item 6552C67500 of the Army's FY2026 Missile Procurement budget, is focused on the ongoing modernization and sustainment of the Multiple Launch Rocket System (MLRS) launcher fleet. The primary goal is to upgrade and extend the operational life of the Army's tracked, indirect fire rocket/missile launchers, ensuring their continued relevance in support of Long Range Precision Fires and Multi-Domain Operations.

The program supports both the conversion of obsolete launchers and the enhancement of existing systems to meet evolving operational requirements, with an Army Acquisition Objective (AAO) of 347 MLRS launchers.

MLRS Fleet Expansion targets the modernization of legacy M270A0 launchers to the advanced M270A2 configuration. This effort, led by Lockheed Martin Missiles & Fire Control in Camden, AR, involves the integration of Improved Armored Cabs (IAC), Bradley commonality upgrades, and the Common Fire Control System (CFCS). The upgrades are designed to enhance survivability, standardize crew procedures, and ensure compatibility with current and future MLRS Family of Munitions, including GMLRS, ATACMS, PrSM, and ER-GMLRS. The Fleet Expansion also addresses recurring obsolescence mitigation, system engineering, and fielding support.

MLRS Fleet Upgrade focuses on inducting M270A1 launchers into a modification line at Red River Army Depot, Texas, upgrading them to the M270A2 standard. This selective upgrade process includes the application of the IAC Modification Kit, procurement of CFCS Launcher Adapter Group (LAG) kits, and implementation of Bradley Engineering Change Proposals (ECPs). The objective is to ensure that the existing fleet remains serviceable through FY2050 or beyond, maintaining operational effectiveness and commonality with other Army platforms. The Fleet Upgrade also includes recurring and non-recurring costs for system engineering, transmissions, engines, and training.

Improved Armored Cab (IAC) is a critical modification element manufactured by American Rheinmetall Defense, Inc. in Lansing, MI. The IAC kit is designed to provide enhanced crew protection against improvised explosive devices (IEDs) and small arms fire, meeting or exceeding the protection level of the M142 HIMARS Increased Crew Protection Cab. The IAC also standardizes crew drills between HIMARS and MLRS operators, improving operational efficiency and safety. Funding in FY2026 supports the procurement of IACs, initial spares, and production line replenishment.

MLRS MODS began receiving dedicated funding in FY2025 to provide transparency for recurring obsolescence mitigation activities not directly tied to the Fleet Upgrade. This line item realigns cost elements such as Bradley chassis and fire control system obsolescence, government testing, logistics-related modifications, product integration support, and software integration support.

The MODS effort ensures that technical data packages, electronic manuals, and training devices are kept current, while systems engineering addresses obsolescence and supports ongoing production and fielding activities.

Justification for the MLRS Mods program centers on maintaining a capable and modernized launcher fleet that can support the Army's transformation initiatives and respond to current and emerging threats. The program is structured to leverage contract negotiations, cooperative partnerships, and cost reduction initiatives to maximize the number of launchers upgraded and address critical obsolescence and modernization requirements. The modifications are necessary for both active and reserve components, supporting homeland defense, domestic emergency response, and military support to civil authorities as mandated by law.
