Armtec Defense Products CO.

Armtec Defense Products Co., a subsidiary of Esterline Technologies Corporation, manufactures advanced ammunition and ordnance components for the Department of Defense as a prime contractor (77% of recent awards) and subcontractor. The company operates as a for-profit manufacturer of goods based in Coachella, California, competing on full-and-open, firm fixed-price contract actions with no set-aside designations. Armtec's core capability centers on combustible cartridge case assemblies, propellant charges, and specialized ordnance components that modernize Army artillery and munitions systems.

Armtec's customer concentration is heavily skewed toward Army ammunition programs. The top five funding entities account for 89% of recent awards by count, dominated by the Department of the Army Acquisition Support Center Program Executive Office Ammunition (36 awards, $2.57 billion combined potential value) — an astronomical concentration that dwarfs all other customers. The same entity also anchors the dollar rankings at $2.57 billion, followed by the Department of the Army Materiel Command Contracting Command Picatinny Arsenal (21 awards, $150.9 million), the Department of the Army proper (60 awards, $144.5 million), the Department of the Navy Naval Supply Systems Command (6 awards, $67.6 million), and the Department of the Army Materiel Command Joint Munitions Command (10 awards, $13.6 million). This customer concentration reflects Armtec's role as the Army's sole-source supplier of Modular Artillery Charge System (MACS) M231/M232-series combustible case assemblies under a $1.897 billion single-award indefinite delivery contract established March 5, 2021. Recent prime delivery orders include a $152.6 million order awarded September 25, 2025, for M232A2 combustible case assemblies (ultimate completion February 28, 2030); a $234.3 million order issued September 25, 2023, for production acceleration to support Ukraine; and a $6.9 million order dated March 3, 2026, for MACS M231/M232-series assemblies (ultimate completion August 31, 2030).

Armtec places task orders under five primary indefinite delivery vehicles. The largest by potential value is Indefinite Delivery Contract W15QKN21D0005, which carries 8 task orders valued at $472.9 million combined potential value and serves as the parent vehicle for most MACS combustible case assembly orders. The vendor also operates under Indefinite Delivery Contract W15QKN15D0004 (12 task orders, $63.6 million), Indefinite Delivery Contract W15QKN07D0007 (18 task orders, $6.5 million), Indefinite Delivery Contract W52P1J18D0059 (11 task orders), and Indefinite Delivery Contract DAAA0999D0013 (9 task orders). Activity has been volatile — four awards in 2022, five in 2023, twelve in 2024, nine in 2025, and one in 2026 — with only one award (combined potential value $21.6 million) facing ultimate completion inside the next twenty-four months, indicating minimal near-term recompete exposure on prime contracts.

In its subcontractor role, Armtec supplies specialized ordnance components to three major defense primes. General Dynamics Ordnance and Tactical Systems is the primary subcontracting customer, with awards spanning mortar propelling charges, 120mm tank training ammunition, 120mm advanced multi-purpose cartridges, M829A4 cartridge cases, and tank armor-piercing ammunition adapters (nine subcontract awards dated June 2022 through September 2025). Alliant Techsystems Operations LLC sources 120mm Advanced Multi-Purpose (AMP) XM1147 cartridges and high-explosive multi-purpose ordnance from Armtec (four subcontract awards, November 2024 through March 2025). Northrop Grumman Systems Corporation sources tank training ammunition for Egypt coproduction and adapter cases (four subcontract awards, June 2024 through December 2024). Armtec also subcontracts to Nammo Defense Systems Inc. and Valkyrie Enterprises LLC for specialized propellant and ordnance work. Across prime and sub work, NAICS concentration is heavy in Ammunition (except Small Arms) Manufacturing (77 awards) and Other Ordnance and Accessories Manufacturing (11 awards), with PSC focus on ammunition over 125mm (25 awards) and 75mm through 125mm (14 awards).
