About the company
Bates Brothers LLC, doing business as Bates Brothers Mechanical, is a Pennsylvania-based limited liability company that subcontracts engineering and logistics support services to prime defense contractors on military aircraft sustainment and modernization programs. The vendor operates exclusively as a subcontractor (100% of recent awards) and holds no independent federal prime contracts or IDVs. Bates Brothers competes in full-and-open subcontract competitions without SBA set-aside designation.
The vendor's recent work concentrates on two prime relationships: Bell Boeing Joint Project Office and The Boeing Company. Under Bell Boeing, Bates Brothers performs V-22 engineering and logistics sustainment support across multiple periods of performance (POP 1, 2, and 3), with awards dated April 2024, February 2025 (two awards), and April 2025. Under Boeing, the vendor supports F-15 Saudi fleet modernization programs (awards in March 2024, July 2024, and November 2024) and the UH-1N replacement program (December 2023 award). A February 2026 sub award represents the most recent activity, continuing V-22 POP 3 work with Bell Boeing.
Customer concentration runs heavily to Navy and Air Force programs. The Department of the Navy Naval Air Systems Command anchors 7 of the 12 recent awards, while the Department of the Air Force Materiel Command Aeronautical Systems Command holds 4 awards and the Department of the Air Force holds 1 award — accounting for 100% of the identified customer base. The vendor's work routes through two indefinite delivery contracts: SPRPA124D9001 (6 task orders) and SPE4AX19D9410 (1 task order), both originating from defense prime frameworks rather than government-wide vehicles.
Capability framing splits between computer systems design services (6 awards) and aircraft parts and auxiliary equipment manufacturing (5 awards), reflecting the mixed nature of engineering, logistics, and manufacturing support on airframe modernization contracts. Activity has grown modestly — two awards in 2023, five in 2024, four in 2025, and one in early 2026 — with combined potential value across all recent awards totaling $867 thousand. The vendor operates at small scale relative to larger defense subs; the subcontract portfolio suggests specialized engineering or manufacturing labor embedded within prime aircraft programs rather than broad program integration or systems capability.
