Mcnally Industries, LLC

Mcnally Industries, LLC, a Wisconsin-based for-profit limited liability company and defense manufacturer, operates as a prime contractor on the federal defense industrial base, delivering specialized mechanical, electronic, and ordnance components and assemblies for naval, air, and land-based military platforms. The vendor competes exclusively full-and-open with no SBA set-aside designations across its footprint; it is not a minority-owned, women-owned, veteran-owned, or small disadvantaged business.

Headquartered in Grantsburg, Wisconsin, Mcnally Industries manufactures high-precision components across a portfolio anchored by small arms, ordnance, and ordnance accessories (133 awards) — particularly 30-millimeter cannon housings, breech assemblies, and recoil mechanisms — followed by aircraft parts and auxiliary equipment, fasteners, valves, and pumps. The vendor holds a single-award Basic Ordering Agreement with Naval Sea Systems Command valued at $45.5 million through September 2027 for the design, manufacture, and overhaul of MK 6 Ammunition Hoist systems used on naval surface ships; this BOA dominates the vendor's revenue footprint and accounts for $112.3 million of the $176.7 million in combined potential value across all federal awards. Beyond the BOA, Mcnally Industries delivers on purchase orders and delivery orders for repair and manufacture of centrifugal pump units (at least five definitive contracts ranging from $330 thousand to $1.96 million each), valve assemblies, gun housings, and ordnance components. The vendor also holds an Army Contracting Command Warren Basic Ordering Agreement for Class IX repair parts and components effective through April 2031, an Indefinite Delivery Contract with Defense Logistics Agency Land and Maritime for Track Assembly, Forward components ($250 thousand ceiling, one-year term), and a $1.65 million Other Transaction Agreement with Army TACOM for additive manufacturing characterization of Abrams tank components completed in July 2025.

Customer concentration is heavily weighted to the Navy and Army. The Department of the Navy Naval Sea Systems Command alone anchors 86 awards (63% of combined potential value), followed by Naval Supply Systems Command (150 awards, $10.1 million). The Department of the Army Materiel Command TACOM Life Cycle Management Command and Contracting Command Detroit Arsenal together account for 96 awards and $9.6 million. Defense Logistics Agency Aviation (59 awards, $5.7 million) and Land and Maritime (133 awards, $5.4 million) round out the top five. Across the top-five customers, Navy programs (both Sea Systems and Supply Systems) represent approximately 63% of combined potential value, with Army and DLA collectively accounting for most of the remainder.

Activity accelerated year over year from 2022 through 2025 — from 11 awards in 2022 to 29 in 2025 — reflecting sustained demand for ordnance and ammunition handling components. The vendor carries a manageable recompete cliff with seven awards (combined potential value $8.7 million) reaching ultimate completion within the next twenty-four months.

Mcnally Industries subcontracts to major primes including Northrop Grumman Systems Corporation (30-millimeter cannon production, XM914E1 and XM813 systems, breech assemblies, and piston rods), Raytheon Company (Close-In Weapon System production, major assemblies, and overhaul work), Renk America LLC (transmission-related components for THOR III Heavy Mine Protected Vehicles), and ES3 Prime Logistics Group Inc. (C-5 aircraft landing gear components). The vendor also maintains sub relationships with Defense Systems and Solutions (H-60M helicopter initial fielding packages), Elbitamerica Inc. (mortar weapons system bipod assemblies), and others. The sub footprint is small (3% of awards by count) but dollar-significant, particularly to Northrop Grumman and Raytheon, reflecting Mcnally's role as a specialized component supplier to the prime contractor tier.

Mcnally Industries' competitive profile centers on manufacturing precision mechanical and ordnance components in low-to-moderate volume, with capability depth in MK 6 Ammunition Hoist systems, pump repair and manufacture, and ordnance-related assemblies. The vendor operates from a single facility in Grantsburg, Wisconsin, and carries established supplier relationships with major defense primes seeking specialized component manufacturing capacity rather than systems-level integration.

Founded in 1942, McNally Industries, LLC proudly serves the United States Department of Defense as a prime contractor for the Mk6 Ammunition Hoist and a subcontractor to many of the world's largest prime contractors delivering hydro-mechanical and electro-mechanical systems, as well as complex, precision machined components for critical defense and aerospace applications.

We offer turnkey solutions for new product design and engineering, reverse engineering, prototype development, build-to-print manufacturing, cable and electrical assembly, and system/subsystem integration, assembly, and test. McNally industries is AS9100 Rev D certified and designated as a Navy Maintenance, Repair, and Overhaul Depot with an onsite DCMA QAR.
