GE Aviation Systems LLC

GE Aviation Systems LLC, a subsidiary of General Electric Company doing business as Dowty Propellers, supplies propeller assemblies, spare parts, overhaul and repair services, and field service support for military transport and maritime patrol aircraft to federal agencies and international partners as a prime contractor (99% of awards). The company competes in full-and-open federal procurement without set-asides, reflecting its status as a large, established defense aerospace contractor specializing in Dowty R391 propeller systems for the C-130J Hercules, HC-130J, and related transport platforms.

GE Aviation Systems LLC operates from Sterling, Virginia as a manufacturer of aircraft components and maintenance, repair, and overhaul (MRO) provider. The company's federal work splits across two capability streams: direct propeller procurement, overhaul, and component repair under prime contracts and subcontracts, and field service representative and technical training support. Recent representative work includes a $39.7 million single-award Indefinite Delivery Contract with the U.S. Coast Guard (awarded January 1, 2025, extending through December 31, 2029) covering repairs, overhauls, and comprehensive support for Dowty R391 propeller assemblies on HC-27J and HC-130J aircraft; a $27.5 million single-award IDC from the Coast Guard (awarded September 5, 2024, through September 4, 2028) for R391 propeller spare parts procurement; and a $29.6 million firm fixed-price delivery order from Naval Air Systems Command (awarded December 1, 2025) for C-130J propeller assemblies, maintenance, and sustainment supporting active and reserve Marine Corps operations across Cherry Point, Miramar, Japan, and Kaneohe Bay.

Customer concentration is extreme. The top five funding agencies account for 75% of recent awards by count and 94% by combined potential value. The Department of the Navy Naval Air Systems Command dominates dollar volume at $489 million combined potential value across 66 awards, anchored by large C-130J Hercules sustainment contracts. The U.S. Coast Guard ranks second by dollars at $160.3 million across 424 awards and drives volume — the vendor maintains multiple indefinite delivery vehicles with the Coast Guard totaling over $77 million in combined ceiling value for HC-130J and HC-27J propeller support. The Defense Logistics Agency Land and Maritime, Warner Robins Air Logistics Complex, and Naval Supply Systems Command round out the active customer set. Recent award activity shows growth: 40 awards in 2022, 36 in 2023, 47 in 2024, 88 in 2025, and 24 so far in 2026 (through mid-May).

GE Aviation Systems LLC holds primary position on five named IDIQs and BPAs: an $39.7 million Coast Guard single-award IDC for C-130/C-27 propeller repairs and overhauls (active January 1, 2025–December 31, 2029); a $27.5 million Coast Guard single-award IDC for R391 propeller spare parts (September 5, 2024–September 4, 2028); a $1,053,039 Coast Guard single-award IDC for R391 system-level propeller training through May 2027; a $10 million DLA Basic Ordering Agreement through October 1, 2029; and a $9.4 million Warner Robins Air Logistics Complex IDC for R391 propeller overhaul through March 26, 2026. Task order velocity under these vehicles remains steady, with 155 orders under one Naval Supply Systems Command IDC and 80 under another, indicating established contracting relationships and streamlined execution. Sixty-five awards with ultimate completion within the next twenty-four months carry combined potential value of $78.6 million, presenting both recompete exposure and opportunity signal for competitors.

GE Aviation Systems LLC operates as a prime on nearly all work (1,265 of 1,283 awards, or 99%); sub-award activity is minimal (18 awards). The company subcontracts to Rolls-Royce Corporation for engine and propulsion-related component support and to Lockheed Martin Corporation for pitch control unit and C-27J propeller repair services. Service Contract Inventory reporting captures $668 thousand in invoiced federal service revenue in FY2024 across 1.1 FTEs, reflecting the limited scope of SCI-reportable labor services — most of the company's federal footprint consists of goods procurement and MRO delivery orders below or outside SCI thresholds. Government-paid hourly rates on captured SCI records run median $298.33/hr.

As a subsidiary of General Electric Company, GE Aviation Systems LLC operates within a parent organization holding multiple large defense contracts. General Electric maintains $5 billion in F110 aircraft engine capacity with the Air Force and $1.128 billion in T700 series turbine engine production authority with the Army, positioning the parent as a primary propulsion systems supplier across Department of Defense aviation infrastructure. This relationship provides GE Aviation Systems LLC with corporate backing and access to parent company supply chain and technical capabilities, though the subsidiary operates as a distinct business unit managing propeller-specific contracts and customer relationships independently.
