Mandus Group LLC

Mandus Group LLC, doing business as Howitzer Repair & Overhaul, is a Rock Island, Illinois-based manufacturer and prime contractor supplying specialized defense logistics equipment and artillery components to the Defense Logistics Agency and Army Materiel Command through full-and-open competition, with no SBA set-aside designations across its federal footprint.

Mandus Group operates as a for-profit limited liability company structured as a manufacturer of goods. The vendor's concrete capability portfolio centers on field maintenance and sustainment equipment for military platforms: lubricant and oil transfer pumps, hydraulic and gun cleaning kits, portable tool boxes and tool chests, oxygen-nitrogen generators, nitrogen intensifiers, and specialized components such as access utility doors, panel inserts, sliding door tracks, and hand launchers. Recent representative work includes a $799.8 million firm fixed-price purchase order from DLA Aviation for fourteen oxygen-nitrogen generator units (awarded December 2023, completing December 2024); a $1.36 million firm fixed-price definitive contract from U.S. Army Materiel Command's TACOM Life Cycle Management Command for modernization of MG3000 gymnasticators at Anniston Army Depot (awarded September 2023, completing August 2024); and a $112.6 million firm fixed-price purchase order from DLA Troop Support for eighteen lubricant transfer pumps (awarded January 2024). The vendor also holds a single-award Indefinite Delivery Contract for nitrogen intensifier supply (awarded October 2025, ceiling $350 thousand, completing October 2026).

Customer concentration is heavily weighted toward Army platforms and Army logistics operations. The top five funding agencies account for 93% of awards by count and 98% of combined potential value. DLA Land and Maritime leads by volume with 362 awards valued at $3.7 million combined potential, followed by DLA Aviation with 111 awards worth $3.3 million. By dollar value, however, the Army's materiel command branches dominate: the Department of the Army Materiel Command Contracting Command Detroit Arsenal anchors $90.5 million across thirteen awards, and TACOM Life Cycle Management Command carries $76.5 million across forty-five awards. This concentration signals that Mandus Group's business is fundamentally anchored to Army platform sustainment rather than distributed across civilian or broader DoD customers.

Activity has grown substantially. Award volume climbed from seventeen contracts in 2022 to seventy-five in 2024, with thirty-nine awards in 2025 and nine year-to-date in 2026. Combined potential value across all prime awards stands at $185.6 million, with $101.6 million obligated (55% invoiced), reflecting a backlog of outstanding delivery orders. Only four awards face ultimate completion within the next twenty-four months (combined potential value $99 thousand), indicating minimal recompete pressure in that window.

The vendor's parent vehicle position is anchored to Army IDIQs. The top-ranked vehicle is Indefinite Delivery Contract W56HZV12D0004, which carries thirteen task orders worth $68.3 million combined potential value. Two additional Army IDIQs—DAAE2001D0050 (twelve task orders) and W52H0906D0053 (ten task orders, $1.5 million)—support significant task order activity. A fourth vehicle, W56HZV09D0138, carries seven task orders worth $4 million. These are not government-wide vehicles; they are Army-specific or DLA-specific IDIQs. Mandus Group does not appear on GSA Schedule or GWAC vehicles.

Category concentration reflects the vendor's product specialization. The top NAICS classifications are Other Electronic Component Manufacturing (242 awards), Metal Crown, Closure, and Other Metal Stamping (78 awards), and Small Arms, Ordnance, and Ordnance Accessories Manufacturing (53 awards). By PSC code, Miscellaneous Maintenance and Repair Shop Specialized Equipment leads with 265 awards, followed by Guns Over 150mm Through 200mm (99 awards) and Tool and Hardware Boxes (84 awards). The vendor has no recorded subcontract activity in the source data; the prime-versus-sub split shows 100% prime awards, 0% sub awards.

Mandus Group operates entirely outside set-aside channels. Every award carries "No Set-Aside Used" designation and was competed full-and-open. The vendor holds federal contractor registration since March 2002 (SAM.gov) and competes on price and capability across routine DLA supply orders and Army platform-modernization contracts, with no socioeconomic program footprint.
