Eaton Corporation

Eaton Corporation's Fuel & Motion Control Systems Division, doing business as Airframe, manufactures aerospace fuel system and motion control components for military aircraft as a prime contractor on full-and-open federal contracts, with no SBA set-aside posture. The division is a subsidiary of Dublin-headquartered Eaton Corporation Public Limited Company and operates from a facility in Irvine, California. Airframe competes as an unrestricted large business across all prime awards and holds no designations as a small, minority-owned, women-owned, or disadvantaged business.

Airframe's federal work centers on specialized fuel and hydraulic valve assemblies, pumps, couplings, and actuators for military aviation platforms. Representative prime work includes a $1.29 million contract from the Air Force Sustainment Center awarded in September 2025 for F-16 fluid filters (79 units), a $1.04 million Naval Supply Systems Command contract from December 2024 for fuel transfer pumps, a $887,730 Defense Logistics Agency contract from June 2025 for F-15 fuel pilot valves, and a $1.42 million Air Force Sustainment Center Indefinite Delivery Contract awarded in December 2025 for remanufacture of KC-135 air refueling and submerged pumps. The division also performs recurring remanufacturing and repair services: KC-135 air refueling pump remanufacture, KC-135 regulated refueling coupling remanufacture, MC-130J and HC-130J boost pump repair, and B-2 actuator remanufacture. These services support the operational readiness of strategic Air Force platforms including the KC-135 Stratotanker, F-15 and F-16 fighters, and specialized operations and rescue aircraft.

Customer concentration is heavily weighted to Defense Logistics Agency logistics operations. Of 1,002 total awards (932 prime, 70 sub), the top five funding agencies account for approximately 91% of volume. The Defense Logistics Agency Aviation branch leads with 368 awards and $35.6 million combined potential value, followed by Defense Logistics Agency Land and Maritime with 257 awards and $25.3 million. The Air Force Sustainment Center is third with 107 awards worth $21.8 million, and Naval Supply Systems Command fourth with 90 awards totaling $11.7 million. The potential-value and award-count rankings align closely—DLA Aviation dominates both dimensions—indicating sustained, volume-based customer relationships rather than a few large programs anchoring the portfolio.

Airframe holds five active single-award Indefinite Delivery Contracts totaling roughly $3.7 million in ceiling value: a $1.42 million IDC with the Air Force Sustainment Center for KC-135 air refueling and submerged pump remanufacture (awarded December 2025, completing December 2028); a $1.27 million IDC with Defense Logistics Agency Aviation for fuel shutoff valves (awarded April 2024, completing April 2027); a $599,651.90 IDC with Naval Supply Systems Command for V-22 valve assemblies (awarded May 2023, completing September 2024); a $218,725.93 IDC with the Air Force Sustainment Center for MC-130J and HC-130J boost pump repair (awarded May 2022, completing May 2027); and a $109,125.10 IDC with the Air Force Sustainment Center for KC-135 regulated refueling coupling remanufacture (awarded May 2024, completing May 2029). Activity has grown year over year—from 16 awards in 2022 to 59 in 2025—though only 8 awards appear in the first quarter of 2026. Sixteen awards with ultimate completion dates in the next twenty-four months carry combined potential value of $5.1 million and therefore face recompete risk.

Airframe subcontracts to Boeing, Sikorsky Aircraft Corporation, Lockheed Martin, Northrop Grumman, Bell Boeing Joint Project Office, and Bell Textron on next-generation and sustainment programs. Boeing sub work spans KC-46 Pegasus development and production (materials and electro-hydraulic-mechanical components), C-17 Globemaster III sustainment, F-15EX advanced procurement, and KC-X modernization efforts. Sikorsky relationships center on Combat Rescue Helicopter components including valve and actuator assemblies. Bell Textron engagement focuses on Future Vertical Lift (FVL) FLRAA development, including non-recurring engineering and pressure refuel adapter assemblies. Northrop Grumman subs involve E-2D Advanced Hawkeye aerial refueling retrofit kits and installation hardware. Lockheed Martin relationships include C-130J sustainment work. Across 70 sub awards spanning 2023 through early 2026, Airframe supplies valves, pumps, actuators, and fuel system components—the same component categories as its prime business—to major primes on both legacy aircraft sustainment and advanced development programs.

The award portfolio concentration by part type is tight. Within the top NAICS categories, Other Aircraft Parts and Auxiliary Equipment Manufacturing (297 awards) and Aircraft Engine and Engine Parts Manufacturing (198 awards) dominate; within PSC codes, Engine Fuel System Components, Aircraft and Missile Prime Movers (227 awards) and Valves, Nonpowered (161 awards) anchor the footprint. This reflects Airframe's core identity: a fuel and motion control component manufacturer positioned as an OEM and monopoly or sole-source supplier for specialized military aircraft subsystems where the customer relies on proprietary engineering data and manufacturing capabilities to sustain in-service fleets.
