About the company
H3 Manufacturing Group LLC Higrade Division, doing business as Hi-Grade Welding And Manufacturing, operates exclusively as a subcontractor on defense manufacturing work, delivering precision-machined components and assemblies to prime contractors on Air Force contracts. The vendor is a self-certified small disadvantaged business (SDB) organized as a limited liability company and headquartered in Schaumburg, Illinois; it is a subsidiary of parent H3 Company Holdings, LLC, also an SDB-certified manufacturer.
H3 Manufacturing's federal footprint consists entirely of subcontract work — four awards aggregating $1.6 million obligated, all delivered to Department of the Air Force Materiel Command Aeronautical Systems Center as the ultimate customer. The vendor subcontracts to CAE USA Inc. on F-16 training simulator programs, delivering display assemblies and video components for the Simusphere 9 Facet high-projector system and VSM Phase 3 architecture (two awards: June 2024 and November 2025). It also subcontracts to BAE Systems Information And Electronic Systems Integration Inc. on Big Safari programs, supplying machined top covers (two awards: April 2024 and October 2024). All four awards fall under primary NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing), consistent with the vendor's positioning as a precision manufacturer for aerospace defense platforms.
Work flows through two parent vehicles: the Basic Ordering Agreement FA862021G4028 (two task orders) and TSA III (two task orders). Activity is minimal and recent — three awards in 2024 and one in 2025 — with no recurring prime posture or government-wide vehicle seats. The vendor operates in a highly concentrated, subcontractor-dependent model serving a single customer agency through two established prime relationships; there is no visibility into pipeline, recompete exposure, or organic growth trajectory within this sparse award window.
