AMTEC CORPORATION

AMTEC CORPORATION specializes in the design, fabrication, and testing of medium- and large-caliber ammunition systems and explosive components for U.S. military applications. Their core technical expertise lies in the production and qualification of 40mm grenade cartridges—including M433 HEDP, M781E1, and M918E2 TP-DNT variants—as well as the refurbishment and integration of firing devices such as the MK-59 MOD 0. The company demonstrates deep proficiency in ballistic testing, environmental conditioning, and production verification cycles, with particular strength in reformulating propellants like PBXN-5 spitback assemblies and adapting munitions to meet extreme temperature and operational durability requirements. AMTEC’s differentiation stems from its ability to execute complex NRE programs and transition prototypes into sustained production, often under tight timelines for urgent warfighter needs, including support for international partner initiatives like the Presidential Ukraine Buyback Effort. The contractor maintains a consistent and exclusive relationship with the Department of Defense, delivering critical ammunition systems through the Army Contracting Command, particularly for Project Manager for Maneuver Ammunition Systems. Their work spans the full lifecycle of munitions—from development and testing to high-volume manufacturing—primarily supporting ground forces with grenade launcher systems, breach rounds, and fuze assemblies. AMTEC’s industry focus is centered on NAICS 332993 (Ammunition Manufacturing, Except Small Arms) and 325920 (Explosives Manufacturing), positioning them as a niche provider of non-small arms ordnance and high-explosive components. They serve the land warfare and tactical munitions vertical, with specialization in 40mm grenade systems and associated firing mechanisms. Based in Janesville, Wisconsin, AMTEC operates as a small business under a 2L entity structure. While no formal government certifications are listed, their sustained DoD contract activity and technical execution in sensitive munitions programs indicate a robust, cleared manufacturing capability aligned with federal defense supply chain requirements.
