Hamilton Sundstrand Corporation

Hamilton Sundstrand Corporation, doing business as Collins Aerospace and operating as a large business subsidiary of RTX Corporation, manufactures and sustains aircraft components, propeller systems, hydraulic and seal assemblies, and electronic control systems for military and commercial aviation platforms as a prime contractor on full-and-open delivery orders, single-award indefinite delivery contracts, and basic ordering agreements issued by defense logistics, naval, and air force agencies. The vendor competes without set-aside designations and does not hold SBA certifications.

The vendor's federal footprint centers on military aviation sustainment. The Defense Logistics Agency Aviation leads by order count at 76,254 awards carrying $1.61 billion combined potential value, reflecting Hamilton Sundstrand's role as a core supplier of aircraft propellers, propeller components, hydraulic system parts, O-rings, packings, gaskets, bearings, gears, shafts, seals, and minor assemblies across the DoD rotorcraft and fixed-wing fleets. The Department of the Air Force Materiel Command anchors the second-largest dollar block, with the Air Force Sustainment Center placing 1,010 orders for $1.32 billion and Robins Air Force Base Lifecycle Management Center authorizing 38 orders for $1.49 billion, predominantly for aircraft component manufacturing, wiring harnesses, and sustainment services supporting B-1, B-2, and F-101 platforms. The Department of the Navy Naval Supply Systems Command issues 2,817 awards valued at $943.6 million for propeller blades, aircraft generators, solenoid valves, motor assemblies, circuit card assemblies, and propeller bulkhead components supporting naval aviation. Naval Sea Systems Command places 326 orders valued at $1.09 billion for field support, design engineering, fuel system components, electrolyzer groom services, and cell stack replacement on attack submarines and related platforms. The vendor's recent award portfolio reflects concentration: 94% of orders are issued by five customer agencies, with DLA Aviation, USAF Sustainment Center, and Naval Supply Systems Command accounting for the vast majority of both order volume and dollar value.

Hamilton Sundstrand's vehicle posture is anchored to indefinite delivery contracts and basic ordering agreements rather than full-and-open single-award contracts. The top five vehicles account for 59,403 task orders and $3.25 billion combined potential value. Indefinite Delivery Contract SPE4AX14D9417 (DLA Aviation) carries 34,904 task orders valued at $74.6 million, serving as the primary vehicle for routine component procurement across DLA Aviation customers. Basic Ordering Agreement SPRPA113G001X (likely a Defense Logistics Agency vehicle) places 8,709 task orders for $551.5 million. Indefinite Delivery Contracts SPE4AX18D9407 and SPE4AX22D9404 carry 5,598 and 5,180 task orders respectively for $198.7 million and $169.5 million combined. Basic Ordering Agreement SPRPA119GCE01 supports 5,012 task orders valued at $296.9 million. A single-award indefinite delivery contract with Naval Sea Systems Command, awarded September 26, 2025, carries a $19.8 million ceiling through September 25, 2030, for field support and design services supporting naval aviation fleet operations, with three delivery orders issued since award for submarine electrolyzer and gas management system support.

The vendor operates with material recompete risk: 1,557 awards (combined potential value $300.2 million) reach ultimate completion within the next twenty-four months, creating a significant pipeline of expiring contracts subject to recompete.

Recent representative prime work spans military aviation components and sustainment. Hamilton Sundstrand was awarded a $2.205 million definitive contract from Naval Supply Systems Command on March 26, 2026, for motor assembly blower components under sole-source terms (the Navy lacked technical data and only approved depot overhaul sources could perform). Delivery orders from the Defense Logistics Agency and Air Force Sustainment Center include a $1.658 million order from DoD Aviation for water and air separators (February 20, 2026), a $1.44 million motor and blower assembly order from Naval Supply Systems Command (April 2, 2026), a $2.042 million aircraft generator order from Naval Supply Systems Command (February 23, 2026), a $1.181 million Weapons Management System order from the Coast Guard (April 15, 2026) for MH-60T aircraft, a $611.8 million wiring harness order from the Air Force Sustainment Center for B-1 aircraft (March 2, 2026), and a $511 thousand housing fuel pump order from the Air Force Sustainment Center for B-2 aircraft (March 30, 2026). The vendor also received a $2.49 million Project Grant from the Department of Transportation Federal Aviation Administration (CFDA 20.115, Fueling Aviation's Sustainable Transition via Sustainable Aviation Fuels and Low-Emissions Aviation Technologies Grant Program) awarded December 1, 2024, for seven research projects evaluating sustainable aviation fuel impacts on aircraft fuel systems and advancing low-emissions propulsion and battery technologies, completing November 30, 2028.

Hamilton Sundstrand holds a secondary subcontractor presence. Sub-work includes contributions to The Boeing Company's C-17 Globemaster III total sustainment program, C-17 virtual fleet material requirements systems, and F-15 conversion support; support to SpaceX's Commercial Crew Transportation Capability contract for crew transportation system integration to the International Space Station; and C-130 supply optimization updates under L3Harris Technologies. The subcontract footprint is minimal (1% of tracked awards) relative to the prime business and does not anchor customer relationships.

The vendor's capability profile is narrowly concentrated in aerospace component manufacturing and sustainment, with top NAICS classifications emphasizing Other Aircraft Parts and Auxiliary Equipment Manufacturing (69,214 awards), Ball and Roller Bearing Manufacturing (5,782 awards), and related equipment. Top PSC codes reflect propeller components (19,117 awards), packing and gasket materials (6,565 awards), O-rings (5,677 awards), hydraulic and de-icing system components (4,958 awards), and bushings and spacers (4,370 awards). Activity has declined from a 2023 peak of 3,830 awards to 362 awards year-to-date in 2026, reflecting the backlog-driven nature of DLA Aviation delivery order issuance and the fact that the source captures only a recent window of activity.

Hamilton Sundstrand is part of RTX Corporation's broader aerospace and defense portfolio and operates alongside named subsidiary Hamilton Sundstrand Space Systems International, Inc., which carries space-related capability framing distinct from the core aviation component and sustainment business represented in the federal award history.
