About this vehicle

The Department of the Army Materiel Command Contracting Command Picatinny Arsenal established this Master IDIQ for M231 and M232-Series Modular Artillery Charge System (MACS) propelling charges on September 10, 2019, with a shared ceiling of $133.2 million. The vehicle's ordering period closed on September 9, 2024, and is no longer open for new task orders.

Despite the closed ordering window, the vehicle remains actively funded. Two task orders valued at $220.3 million were awarded in September 2025—after the ordering deadline—indicating the Army continues releasing delivery orders against the existing Master IDIQ structure through final completion dates extending to 2030. The most recent award (September 4, 2025) totaled $220.3 million for M232A2 and M231/M232A2 manufacture, assembly, and packaging. Ordering momentum peaked in 2023 and 2024 with four orders per year; 2025 has seen two orders to date.

The vehicle funds production of modular incremental-charge systems compatible with all current 155mm field artillery weapons. M231 charges support Low Zones (1 and 2) used singularly or in pairs; M232-Series charges support High Zones (3, 4, and 5) used in groups of three to five. Task orders also fund significant capacity increases—two orders from December 2024 ramped production from 25,000–50,000 units per month to 80,000 units per month. Orders heavily support Ukraine military assistance, with four task orders explicitly designated for Ukrainian propelling charge procurement totaling approximately $258 million obligated.

Competition is concentrated: American Ordnance LLC holds nine of seventeen task orders with $238 million combined potential value; General Dynamics-Ots, Inc., holds eight orders with $223.6 million combined potential value. All task orders are unrestricted (no set-aside used).

Combined task-order potential value totals $461.6 million, though obligated amounts reach $633.5 million—a 137% ratio reflecting multiyear funding across long completion horizons. The Army directly funds approximately $174.7 million; PEO Ammunition funds $286.8 million, the larger portion. All orders use firm fixed pricing.

Description

The MACS LAP consists of two types of propelling charges, the M231 and the M232-Series, and all associated packaging. It uses a "build-a-charge," incremental-based system; the M231 is used singularly or in pairs for Low Zones (1 & 2) and the M232-Series is used in groups of 3, 4 or 5 charges for High Zones (3, 4 & 5). The system is compatible with all current 155mm field artillery weapons.
