About the company
CSI Manufacturing Inc., a for-profit Subchapter S corporation based in Westborough, Massachusetts, manufactures precision electro-optical and night-vision subsystems and components for the Department of the Army as a subcontractor only — the vendor holds no prime contracts or IDVs in federal work.
CSI operates exclusively as a subcontractor on Army programs, with no direct federal prime posture. The vendor's recent activity spans seven awards issued between January 2024 and November 2025, all subcontract placements totaling $511 thousand in combined obligation. Work concentrates on two Army customers: the Department of the Army Acquisition Support Center PEO Soldier (four awards) and the Department of the Army Materiel Command Contracting Command Detroit Arsenal (three awards). NAICS classification splits between Commercial and Service Industry Machinery Manufacturing (four awards) and Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing (three awards), reflecting the vendor's focus on subsystems for ground combat systems.
CSI's recent subcontract footprint centers on two major Army programs: the Enhanced Night Vision Goggle-Binocular (ENVG-B) and the AN/PEQ-15 Infrared Illuminator. Under L3 Technologies as prime, CSI supplies contact assemblies for ENVG-B production systems (three sub awards: June 2025, September 2025, March 2025). For the AN/PEQ-15 program, CSI holds five-year requirements contracts for component manufacturing — mounting ring diodes, battery inserts, and battery caps (awards dated April 2025, September 2024, and November 2025). These are production-volume subcontracts rather than development work, with CSI operating as an approved vendor on multi-year supply lines. The single named prime is L3 Technologies; other unnamed primes are implied by the remaining sub awards but not disclosed in the source.
Activity has accelerated from two awards in 2024 to five in 2025, suggesting ramp on established programs. No recompete cliff is noted. CSI has not pursued or won federal prime contract vehicles and does not operate under GSA Schedules, GWACs, or set-aside certifications documented in this source. The vendor's federal presence is narrow and specialized — a component supplier to legacy Army night-vision platforms competing through established subcontractor relationships rather than through competitive procurement vehicles.
