TNT and PBXN-9 Supplementary Charges

The TNT and PBXN-9 Supplementary Charges Master Indefinite Delivery/Indefinite Quantity (IDIQ) contract, awarded by the Army Contracting Command-Rock Island, facilitates the production and delivery of critical explosive components used in artillery projectiles. Specifically, the contract covers the manufacture of TNT and PBXN-9 supplementary charges, which serve as critical boosters between fuzes and main charges in 105mm and 155mm ammunition systems. These supplementary charges, each containing approximately 0.33 pounds of pressed pellets in an aluminum body cup, are essential for supporting training and operational requirements for U.S. military forces.

The contract has been primarily executed through delivery orders awarded to two prime contractors: Spectra Technologies LLC and Accurate Energetic Systems LLC. Delivery orders typically range from $850,000 to $8.1 million, with performance periods extending 12-36 months, and consistently use firm fixed-price pricing without specific set-aside designations. Task orders have included quantities ranging from 97,920 to 325,000 supplementary charges, with the Department of the Army's Program Executive Office (PEO) Ammunition as the primary funding agency. Performance locations include Tennessee and other undisclosed manufacturing facilities, with both contractors demonstrating capability to produce these specialized energetic components for domestic Army and Marine Corps requirements, as well as potential foreign military sales. The master IDIQ has a total ceiling of $45 million and is structured to support ammunition requirements through multiple ordering periods from fiscal year 2019 to 2023.
