American Ordnance LLC

American Ordnance LLC, doing business as American Ordinance Iowa Operation, manufactures conventional munitions and operates the Iowa Army Ammunition Plant as a prime contractor for the Department of Defense, competing full-and-open without set-asides across ammunition production, load-assemble-pack operations, and facility support services. The company is a for-profit limited liability company and subsidiary of The Day & Zimmermann Group Inc., headquartered in Philadelphia, and operates from Middletown, Iowa.

American Ordnance's capability footprint centers on 155mm projectile manufacturing and load, assemble, and pack (LAP) operations; 60mm, 81mm, and 120mm mortar propelling charge production; Mine Clearing Line Charge (MICLIC) and M112 demolition charge systems; and facility maintenance and infrastructure support at military ammunition plants. Recent representative awards include a $974.4 million single-award IDV for manufacture, test, packaging, and delivery of 155mm M1128 high-explosive projectiles supporting Ukraine through September 2028; a $499.2 million multiple-award contract for 60mm, 81mm, and 120mm mortar propelling charge production through September 2029; and a $304 million single-award contract for Mine Clearing Line Charges and M112 demolition charges. Delivery orders under these vehicles total hundreds of millions in annual value—a $157.7 million order for LAP on 346,478 units of 155mm M795 projectiles (September 2024), a $119.3 million order for LAP on 388,436 units of 155mm M795 TNT-loaded projectiles (September 2025), and a $59.4 million order for M232A2 modular artillery charge system LAP (September 2025).

Customer concentration is heavily skewed to the Army's ammunition enterprise. The top three customers account for more than 97% of award count and 100% of potential value: the Department of the Army Acquisition Support Center Program Executive Office Ammunition (296 awards, $9.38 billion potential value), the Department of the Army Materiel Command Joint Munitions Command (693 awards, $718.2 million), and the Department of the Army (241 awards, $497.1 million). A small secondary set includes the Department of the Army Research Development and Engineering Command (19 awards, $30.4 million) and Naval Sea Systems Command (12 awards, $5.1 million).

American Ordnance's vehicle position is dominated by two major IDVs. The Blanket Ordering Agreement W52P1J-09-G-0001 under PEO Ammunition supports 633 task orders worth $787.8 million in combined potential value for facilities operations, maintenance, and infrastructure projects at Iowa and Milan ammunition plants. The multiple-award IDIQ W52P1J04G0002 carries 124 task orders valued at $31 million. The company also holds single-award IDVs for 155mm M1128 projectile production ($974.4 million ceiling), 60mm/81mm/120mm mortar propelling charges ($499.2 million), Mine Clearing Line Charges and M112 demolition charges ($304 million), and 40 LB cratering charges ($68.5 million).

Activity has remained stable over the past five years: 36 awards in 2022, 62 in 2023, 48 in 2024, 49 in 2025, and 4 in 2026 year-to-date. Recompete exposure is material—39 awards with combined potential value of $810.4 million complete within the next twenty-four months, creating significant opportunity for competitors on 155mm projectile LAP, mortar propelling charge, and MICLIC production renewals.

American Ordnance subcontracts to specialized suppliers on specific tasks. Recent subs include Milan Box Corporation (veteran-owned small business) for M112 wire bound boxes; Vac Pac Inc. (woman-owned small business) for demolition charge containers; Wells Technology and Flick Packaging (HUBZone-certified small businesses) for tape and pallets; and GBA Builders LLC for facility design work. Teaming on prime work spans companies like Triad National Security (Los Alamos National Laboratory operations support), General Dynamics Ordnance and Tactical Systems (120mm training ammunition), and Southwest Research Institute (shaped charge redesign and LX-14 billet fabrication).

The company's top NAICS codes reflect dual-mission capability: Facilities Support Services (639 awards) and Ammunition (except Small Arms) Manufacturing (537 awards), with smaller exposure in Explosives Manufacturing (12 awards) and Small Arms Ammunition Manufacturing (7 awards). Top PSC codes confirm operational focus on Ammunition Facility Operations (413 awards) and Housekeeping-Facilities Operations Support (290 awards). Total award footprint spans 1,305 awards across a combined $10.66 billion potential value, with $3.88 billion obligated (36% execution rate). Day & Zimmermann Group's ownership brings construction, engineering, and staffing capabilities that support American Ordnance's facility management and infrastructure mission beyond core munitions manufacturing.
