General Dynamics-Ots, Inc.

General Dynamics-Ots, Inc.'s Ordnance and Tactical Systems Division, doing business as GD-OTS (Williston), manufactures precision military components, ammunition handling systems, and ordnance accessories as a wholly owned subsidiary of General Dynamics Corporation, competing exclusively on a full-and-open basis with no SBA set-aside posture. The division operates manufacturing facilities in Colchester and Saco, Maine; Williston, North Dakota; and St. George, Vermont, and derives its federal footprint almost entirely from prime contracts (99% of awards) rather than subcontract work.

GD-OTS's capability portfolio centers on small arms and ordnance accessories manufacturing (NAICS 332994), mechanical power transmission equipment (NAICS 333612–333613), and aircraft parts. Concrete examples include a $900 million Indefinite Delivery Requirements contract from PEO Ground Combat Systems awarded September 2025 for active protection systems and contractor logistics support for the Bradley Fighting Vehicle, with performance through December 2032; a $26.5 million delivery order from PEO Ground Combat Systems in July 2026 for countermeasure munitions for the B-Kit; a $2.35 million definitive contract from Defense Logistics Agency Land and Maritime in December 2025 for drum assemblies for ammunition; a $1.69 million definitive contract from DLA Land and Maritime in December 2025 for entrance unit, gun system components; a $1.42 million definitive contract from DLA Aviation in March 2026 for gun drive assemblies for aircraft; and a $1.29 million definitive contract from DLA Land and Maritime in April 2026 for 20 mm barrel sets. The division executes hundreds of smaller firm fixed-price purchase orders annually, typically ranging from $5,000 to $350,000, for components including cartridge guides, ammunition conveyors, gears, shafts, housing assemblies, and mechanical parts.

Customer concentration is extreme and heavily weighted toward defense logistics. The Defense Logistics Agency Land and Maritime alone accounts for 4,482 of the 6,771 total awards in the source dataset (66% of award count) with a combined potential value of $479.6 million. The Naval Supply Systems Command follows with 571 awards worth $93.8 million, and DLA Aviation with 439 awards worth $26.1 million. Across the top five customer agencies by award count (DLA Land and Maritime, Naval Supply Systems Command, DLA Aviation, DLA Troop Support Hardware, and DLA general), the combined coverage reaches 86% of awards. When ranked by potential value, however, the distribution shifts: the Department of the Army Materiel Command Aviation and Missile Life Cycle Management Command leads with 21 awards worth $1.93 billion, Army Materiel Command Contracting Command Detroit Arsenal contributes 49 awards worth $1.36 billion, the United States Marine Corps places 50 awards worth $996.3 million, Army PEO Soldier contributes 26 awards worth $961.6 million, and Naval Sea Systems Command adds 145 awards worth $890.1 million. These top five customers by dollar value account for 43% of combined potential value across the entire portfolio.

GD-OTS operates on five primary parent vehicles. The Indefinite Delivery Contract SP074003D9732 (DLA Land and Maritime) carries 170 task orders. Indefinite Delivery Contract SPM7LX13D0050 (DLA Land and Maritime) carries 158 task orders with $10.7 million combined potential value. Indefinite Delivery Contract SPM7LX13D0048 (DLA Land and Maritime) carries 118 task orders worth $35.1 million. Indefinite Delivery Contract SPM7LX13DP050 (DLA Land and Maritime) carries 106 task orders worth $2 million. Naval Supply Systems Command Indefinite Delivery Contract N0038302G014G carries 86 task orders. The division also holds three single-award IDIQs: a $350,000 contract with DLA Aviation through May 2029, a $350,000 contract with DLA Aviation through April 2029, and the $900 million Bradley Fighting Vehicle IDR with PEO Ground Combat Systems through September 2032.

Activity has remained relatively flat over the past five years (2022: 250 awards; 2023: 264; 2024: 253; 2025: 259; 2026: 101 year-to-date through mid-July), with 6,771 total awards recorded across the dataset period. The recompete cliff in the next twenty-four months presents material exposure: 207 awards with combined potential value of $533.3 million are scheduled for ultimate completion within that window.

GD-OTS subcontracts to Raytheon Company on Close-In Weapon System (CIWS) Phalanx production and general engineering services, delivering precision-machined components, structural assemblies, hydraulic and electromechanical assemblies, and custom circuit card assemblies. The division also subcontracts to General Dynamics Land Systems Inc. on Optionally Manned Fighting Vehicle development. Sub work accounts for only 1% of the award count (100 sub awards against 6,671 primes), reflecting GD-OTS's role as a direct supplier to federal agencies rather than a traditional systems integrator.

GD-OTS is categorized within NAICS 332994 (Small Arms, Ordnance, and Ordnance Accessories Manufacturing) for 2,781 awards, with secondary concentration in NAICS 333612–333613 (mechanical power transmission equipment) for 1,132 awards, and NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) for 637 awards. PSC concentration mirrors this distribution, with Guns Through 30mm (PSC code—primary) accounting for 3,125 awards, Miscellaneous Power Transmission Equipment (PSC 30) for 780 awards, and Gears, Pulleys, Sprockets (PSC 30) for 767 awards.
