About the company
Waltonen Engineering Inc., a Warren, Michigan-based small business OEM Tier 1 supplier and manufacturer of precision-engineered components and mechanical assemblies, operates as a prime contractor (77% of recent awards) and subcontractor on Department of Defense and Army vehicle sustainment and modernization programs under total small business set-asides and full-and-open competition. The company is a Subchapter S corporation with over 50 years of federal contracting experience and holds two subsidiaries: Independence Tooling Solutions LLC and WS3 LLC.
Waltonen's federal footprint centers on Army logistics and vehicle platforms. The top customer by combined potential value is the Department of the Army Materiel Command's Contracting Command Detroit Arsenal (six awards, $1.54 billion combined potential value), followed by the Department of the Navy's Naval Sea Systems Command (five awards, $1.05 billion), and the Army Materiel Command's TACOM Life Cycle Management Command (16 awards, $434.1 million). These three customers account for 27 awards and approximately $3.02 billion of the $3.03 billion combined potential value across all awards in the portfolio. Waltonen's recent TACOM work illustrates its prime capability: a $140,000 total small business set-aside purchase order (August 2024) for 80 mount assemblies (NSN 2350-01-652-2072) under a one-year option exercise, a $106,915 total small business definitive contract (March 2026) for 125 retaining ring assemblies with an option for an additional 125 units, a $104,105 total small business purchase order (November 2025) for support structural crossmembers (NSN 1095-01-330-8880), and a $66,122 total small business purchase order (September 2025) for GPS stand assemblies (NSN 4931-01-083-2057).
Vehicle position reflects the company's multi-layered approach to compete for federal work. Waltonen holds a $1 trillion ceiling OASIS+ Total Small Business multiple award IDIQ with the General Services Administration's Federal Acquisition Service (awarded December 2024, performance through December 2029) enabling task orders across seven functional domains including Management and Advisory, Technical and Engineering, and Research and Development. The company sits on a $1 billion blanket purchase agreement with Naval Sea Systems Command for machine shop services and engineering support (single award, through April 2026); a $910 million Equipment Related Services multiple award IDIQ with Army TACOM (July 2022 through July 2027) for logistics management, product assurance, and test services; a $50 million multiple award IDIQ with Naval Sea Systems Command for rapid machining assembly (through May 2028); and a newly awarded $151 billion Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple award IDIQ with the Missile Defense Agency (December 2025, through December 2035, full and open competition, no set-aside). A Basic Ordering Agreement for Class IX supplies was established with Army Contracting Command Warren on April 3, 2026, through April 2031, under the BOAST program, with no ceiling value specified.
Activity trajectory shows growth from two awards in 2022 to ten in 2025, with two awards in 2026 to date. Only one award (combined potential value $107 thousand) faces ultimate completion within the next twenty-four months, indicating a favorable recompete cliff position. The company reports combined dollars obligated of $24.3 million against $3.03 billion combined potential value across all awards, reflecting the early-stage execution status of large-ceiling vehicle awards.
Subcontract footprint centers on General Dynamics Land Systems Inc., where Waltonen performed modeling and simulation of vehicle dynamics for the M2 A3 Bradley (August 2025) and participates in prototype deliverables for the Optionally Manned Fighting Vehicle (November 2025, July 2025, January 2025 awards). Waltonen also subcontracts to Amentum Services Inc. on Ukraine-related ground equipment work (February 2024). Grant work includes sub-recipient status under Wichita State University for digital twin development of the Bradley M2 A3 Fighting Vehicle supporting the Ground Vehicle Systems Center (awards April 2025 and February 2024).
The vendor's category concentration (NAICS and PSC) reveals defense systems engineering depth: 11 awards in R&D within physical, engineering, and life sciences; 8 in military armored vehicle and tank component manufacturing; and four each in engineering services and testing laboratories. PSC coding surfaces five awards in R&D defense systems weapons (basic research) and four in R&D general science and technology engineering (advanced development), with three awards each in hardware/commercial and professional engineering/technical support codes.
