MLRS Product Improvement Program

The MLRS Product Improvement Program (Program Element 0603778A) is a key Army research, development, test, and evaluation (RDT&E) initiative focused on the continued modernization and enhancement of the Army's rocket launcher fleet, specifically the M270A1/A2 Multiple Launch Rocket System (MLRS) and the M142 High Mobility Artillery Rocket System (HIMARS). This program is designed to ensure these platforms remain viable, effective, and interoperable in support of the Army's Long Range Precision Fires modernization efforts and broader transformation initiatives. The program's objectives are centered on maintaining technological relevance, integrating new capabilities, and addressing emerging threats, with a particular emphasis on software and hardware upgrades, obsolescence mitigation, and the integration of advanced navigation and communications technologies.

Project 093: Multi-Launch Rocket System (MLRS) is dedicated to the ongoing development and improvement of the M270A2 MLRS launcher, a tracked, indirect fire system capable of delivering a variety of precision munitions, including the Guided MLRS (GMLRS), Army Tactical Missile System (ATACMS), Precision Strike Missile (PrSM), and future Extended Range GMLRS (ER-GMLRS). The project's specific goals include software development for the fire control system, updates to training materials, and the integration of Assured Positioning, Navigation, and Timing (APNT) technologies. These efforts are intended to ensure the MLRS can operate effectively in contested environments, maintain compliance with evolving cybersecurity requirements, and remain interoperable with current and future munitions.

A major objective within Project 093 is the integration and development of the Next Generation APNT Receiver. This effort will replace the existing M-code receiver with an upgraded version (Increment 2), addressing obsolescence and enhancing resilience against advanced electronic warfare threats. The new receiver is expected to incorporate features such as alternative navigation methods, timing holdover, network-assisted assurance, advanced anti-jam capabilities, and beamforming. This upgrade is critical for maintaining the MLRS's operational effectiveness in GPS-denied or contested environments and is aligned with statutory requirements for M-code integration.

Project DX8: HIMARS Product Improvement Program focuses on the M142 HIMARS launcher, a wheeled, highly mobile system that supports rapid deployment and precision fires. The project's objectives mirror those of the MLRS effort, including software development for the fire control system, APNT technology integration, and the implementation of satellite communications and cybersecurity enhancements. The HIMARS project also addresses obsolescence mitigation for key components such as the Family of Medium Tactical Vehicles (FMTV) carrier, launcher loader module, and command and control systems.

For both MLRS and HIMARS, the program funds non-recurring engineering and technical assessments to support system hardware and software modernization, electronic obsolescence mitigation, and risk reduction. These activities are managed by the U.S. Army Combat Capabilities Development Command (DEVCOM) and involve collaboration with industry partners such as BAE Systems and Lockheed Martin Missiles and Fire Control.

The program also supports test and evaluation activities at Army facilities including Aberdeen Proving Ground, White Sands Missile Range, and Redstone Arsenal. A shared goal across both projects is the development of common solutions and software baselines that can be applied to both launcher platforms, thereby reducing sustainment costs and enhancing interoperability. The program supports annual test and evaluation cycles to validate new capabilities and ensure compliance with Army standards for command, control, communications, computers, and intelligence (C4I) interoperability and information assurance.
