MLRS Reduced Range Practice Rockets (RRPR)

The MLRS Reduced Range Practice Rockets (RRPR) program is a key line item in the Army's missile procurement budget, supporting the acquisition of Low Cost Reduced Range Practice Rockets (LCRRPR) for use with the Multiple Launch Rocket System (MLRS) and High Mobility Artillery Rocket System (HIMARS). The primary goal of this program is to provide live training munitions that enable MLRS and HIMARS units, both in the Active Army and National Guard, to meet annual qualification and pre-deployment requirements. This ensures that artillery units maintain a high level of combat readiness and proficiency in operating these complex rocket systems.

The LCRRPR is specifically designed as an inert, reduced-range rocket that allows for realistic training while minimizing safety risks and range requirements. The rocket features a blunt nose and inert payload, which limits its range and makes it suitable for use at a wider variety of training facilities, both domestically and abroad. The use of these practice rockets is critical for units assigned to Brigade Combat Teams (BCTs), Joint Expeditionary Forces, and Joint Special Operations Forces. This capability allows them to conduct live-fire exercises without the logistical and safety constraints associated with full-range, live warhead munitions.

Procurement objectives for FY 2026 include the acquisition of additional LCRRPRs. This represents an increase in both quantity and funding compared to previous years, reflecting the Army's commitment to maintaining adequate training inventories and supporting a larger number of units. The procurement strategy prioritizes production at the Letterkenny Munitions Center (LEMC) in Chambersburg, Pennsylvania, which serves as the primary organic production facility. Lockheed Martin in Camden, Arkansas, is maintained as a secondary source to ensure production resilience and flexibility.

The program's funding also covers a range of associated costs beyond the rockets themselves. These include bunker storage, procurement of performance-oriented packaging boxes, inert warheads, reworked igniters, and the procurement or repair of launch pod containers. Additionally, funds are allocated for the download, demate, and inspection of M-26 rocket motors, as well as for addressing obsolescence issues. Production verification testing, first destination transportation, and production engineering support are also integral components of the program's objectives, ensuring the reliability and safety of the training rockets delivered to units.

Management and oversight of the MLRS RRPR program are conducted by the Army's Aviation and Missile Command (AMCOM) at Redstone Arsenal, Alabama. The program leverages a combination of Sole Source/Indefinite Delivery Indefinite Quantity contracts and Military Interdepartmental Purchase Requests to facilitate timely and cost-effective procurement. The Army actively seeks to convert any price advantages gained through contract negotiations, other service procurement, or foreign military sales into additional rocket purchases, maximizing the value of appropriated funds.

Justification for the program is grounded in statutory requirements, including Section 1815 of the FY 2008 National Defense Authorization Act, which mandates the provision of training munitions for both active and reserve components. The RRPR inventory supports not only routine training and qualification but also homeland defense missions, domestic emergency response, and military support to civil authorities. Maintaining a robust inventory of practice rockets is essential for ensuring that artillery units are fully prepared to respond to a wide range of operational scenarios.
