Day and Zimmerman, Incorporated specializes in the precision manufacturing and assembly of medium- and large-caliber ammunition systems, with deep expertise in 60mm and 81mm high explosive (HE) cartridges and full-range practice rounds. The company performs end-to-end load, assemble, and pack (LAP) operations, including first article testing (FAT) and engineering change proposal integration, ensuring full compliance with military ballistic and safety standards. Their technical proficiency spans propellant loading, fuze assembly, casing integration, and quality assurance protocols for munitions used in mortar systems, with a proven ability to execute complex production modifications under strict defense specifications. This focused capability distinguishes them as a reliable source for mission-critical ammunition components requiring consistent performance and rigorous documentation. The contractor maintains an exclusive relationship with the Department of Defense, consistently delivering ammunition production and modification services across multiple branches and combat support commands. Their work supports frontline infantry and artillery units through the sustained supply of standardized, battle-ready munitions, demonstrating a long-standing trust in their ability to meet urgent operational requirements with high fidelity and on-time delivery. Operating under NAICS 332993, the company is positioned as a niche manufacturer in the non-small arms ammunition sector, serving the DoD’s sustained need for mortar ordnance and training rounds. Their vertical specialization lies in the production of 60mm and 81mm systems, a critical segment of indirect fire support logistics. They are not a generalist but a targeted supplier with deep domain knowledge in artillery cartridge lifecycle management. Day and Zimmerman, Incorporated is a small, privately held entity based in Parsons, Kansas, with no federal certifications on record. Their geographic footprint is limited to their primary manufacturing facility, where they operate as a specialized defense subcontractor focused exclusively on ammunition production for U.S. military requirements.
