GE Aviation Systems LIMITED

GE Aviation Systems LIMITED, operating through its Dowty Propellers Division and headquartered in Gloucester, United Kingdom, is a foreign-owned manufacturer supplying aerospace propulsion components and propeller systems to the U.S. Department of Defense as a subcontractor (84% of recent awards) and occasional prime contractor (16%) under full-and-open competition with no SBA set-asides. The vendor is a subsidiary of General Electric Company and competes across multiple parent IDIQs with the Air Force and Navy without set-aside protection.

Dowty Propellers delivers concrete aerospace components — propeller assemblies, overspeed governors, de-icing units, propeller blades, auxiliary fuel pumps, power control units, bearings, gaskets, seal assemblies, and specialized repair and engineering services for military aircraft propulsion systems. Representative prime work includes a $2,112.86 purchase order from the Department of Defense Aviation agency (awarded December 2025, ultimate completion July 2026) for a bearing roller component; a $59,878 delivery order from Naval Sea Systems Command (September 2025) for LCAC propeller system repair process development and engineering support; a $36,524.88 purchase order from the Air Force's Warner Robins Air Logistics Complex (April 2024) for calibration of Dowty C-130J master blades; and a $7,731.02 delivery order from Naval Sea Systems Command (October 2024) for quarterly ACV propeller system meetings. The vendor's sub work is substantially larger in volume and concentrated under two primes: Lockheed Martin (the majority of C-130J propeller component and engineering subs, including C-130J Combined Aircraft Delivery Development Integration and Engineering [CADDIE] and Five Year Ordering Contract [FYOC] work) and Textron Systems (LCAC long-lead-time propeller material purchases). Recent sub awards from Lockheed Martin span propeller assemblies, overspeed governors, propeller control units, de-icing timer units, brush blocks, spinners, and beta tubes for C-130J aircraft; recent Textron subs cover LCAC 109, 110, and future LCAC 100-class craft long-lead propeller material.

Customer concentration is heavily skewed toward defense platforms. By award count, the Department of the Air Force Materiel Command's Aeronautical Systems Center anchors 77 of 117 awards, followed by Naval Sea Systems Command (25 awards, $1.4 million combined potential value) and the Air Force Materiel Command's Lifecycle Management Center at Wright Patterson Air Force Base (9 awards). By potential value, Naval Sea Systems Command dominates at $1.4 million of the $1.5 million combined potential value across all awards, with the Air Force's Warner Robins Air Logistics Complex contributing $37 thousand. The concentration disparity reflects Dowty Propellers' role as a high-volume supplier under standing Air Force contracts that issue dozens of small purchase orders and delivery orders (largely sub-awarded through Lockheed Martin and Textron) alongside a smaller but more visible prime presence with the Navy.

Dowty Propellers places work through three parent indefinite delivery contracts: Air Force IDC FA862520D3000 (48 task orders), Air Force IDC FA862516D6458 (38 task orders), and Navy N6133118D0013 (8 task orders, $128 thousand combined potential value). These vehicles are the primary channels for routine component procurement and sustainment across C-130J aircraft and naval vessel propulsion systems.

Activity has accelerated sharply. Awards per year jumped from two in 2021 and three in 2022 to 19 in 2023, then 63 in 2024, with 23 awards through 2025. However, the combined potential value of $1.5 million across 117 awards masks significantly higher obligated dollars — $65 million obligated across all awards — indicating that the vendor's listed potential values understate real performance scale, a pattern common in supply contracts where final invoice amounts exceed contract ceilings. Only two awards (combined potential value $62 thousand) face ultimate completion inside the next twenty-four months, indicating minimal recompete exposure in the near term. By NAICS, the work breaks across Aircraft Manufacturing (86 awards), Other Aircraft Parts and Auxiliary Equipment Manufacturing (13 awards), and Ship Building and Repairing (12 awards), reflecting the vendor's role as both an aircraft propulsion OEM and a naval platform component supplier.
