GE Aviation Systems LLC

GE Aviation Systems LLC, a subsidiary of General Electric Company operating as Dowty Propellers, manufactures and delivers propeller assemblies, spare parts, overhaul and repair services, and field service support for military transport and maritime patrol aircraft as a full-and-open prime contractor competing without set-asides on contracts valued at $1.01 billion combined potential across 1,294 recent federal awards.

GE Aviation Systems LLC specializes in Dowty R391 propeller systems for the C-130J Hercules, HC-130J, and HC-27J platforms, with capability spanning propeller component procurement, detailed overhaul and maintenance, field service representative deployment, and technical training. Representative prime work includes a $39.7 million single-award indefinite delivery contract with the U.S. Coast Guard (January 1, 2025–December 31, 2029) for repairs, overhauls, and comprehensive support services for R391 propeller assemblies on HC-27J and HC-130J aircraft; a $27.5 million Coast Guard single-award IDC (September 5, 2024–September 4, 2028) for R391 propeller spare parts procurement; a $21.3 million Naval Air Systems Command delivery order (December 1, 2023) for United States Marine Corps Active PEARLS (Propeller Engine Availability Readiness Logistics Support) sustainment covering propeller maintenance, field service repairs, and engineering services across Cherry Point, Miramar, Japan, and Kaneohe Bay; and a $29.4 million Naval Air Systems Command delivery order (December 1, 2025) for C-130J propeller assemblies, maintenance, and sustainment supporting active and reserve Marine Corps operations across multiple locations. Recent task order activity reflects firm fixed-price delivery orders for propeller overhauls ($267,038–$672,168), propeller assembly procurement ($938,725–$9.3 million), and spare parts and components ($4,655–$2.93 million) issued by Coast Guard, Naval Air Systems Command, and Defense Logistics Agency across Sterling, Virginia and forward-deployed locations.

Customer concentration sits with Navy and Coast Guard aviation logistics. The top five funding agencies account for 94% of combined potential value: Naval Air Systems Command (66 awards, $488.8 million), the Coast Guard (432 awards, $164.2 million), the Air Force Materiel Command Warner Robins Air Logistics Complex (40 awards, $112.4 million), the Air Force Lifecycle Management Center Robins AFB (41 awards, $95 million), and Naval Supply Systems Command (297 awards, $82.2 million). The Coast Guard dominates by award count (432) but Naval Air Systems Command anchors the dollar-value ranking, creating a two-tiered customer base: high-volume Coast Guard sustainment work and large Naval Air Systems Command program delivery orders tied to C-130J major defense acquisition program activity.

GE Aviation Systems LLC holds multiple indefinite delivery contracts serving as parent vehicles for task order issuance. Top vehicles include an Indefinite Delivery Contract N0010405GA109 with 155 task orders and $16.5 million combined potential value; IDC N0010400GA115 with 80 task orders; Coast Guard IDC 70Z03820DW0000001 with 67 task orders and $16.1 million combined potential value; Basic Ordering Agreement SPE4A125G0018 with 52 task orders and $2.4 million combined potential value; and IDC N0001917D0089 with 37 task orders and $84.1 million combined potential value. These vehicles enable sustained task order velocity across fiscal years and position the vendor as the primary approved propeller system supplier for Coast Guard and Naval Air Systems Command operations.

Activity has grown year over year — 40 awards in 2022 to 88 in 2025 — with 61 awards (combined potential value $78.5 million) reaching ultimate completion inside the next twenty-four months and therefore presenting recompete exposure. This recompete cliff reflects expiring task orders and option periods on Coast Guard and Naval Air Systems Command propeller sustainment IDCs.

Service Contract Inventory data captures SCI-reportable invoicing of $1.7 million across FY2022–FY2025, with FY2024 at $668 thousand and FY2025 at $1.1 million; the SCI dataset shows roughly 1.1 FTEs delivered to the federal government in FY2024, with 0.0 FTEs in FY2025 (reflecting the episodic nature of labor-intensive propeller overhaul work and the project-based structure of task order delivery). SCI median government-paid rates ran around $298.33/hr. SCI is a partial view excluding goods, products, classified work, and non-federal revenue; these figures capture only service contracts above the $150,000 reporting threshold and significantly understate the vendor's total federal aerospace and defense revenue tied to propeller manufacturing, component procurement, and overhaul operations.

GE Aviation Systems LLC operates as a prime on 99% of recent awards and as a subcontractor on 1%, indicating a build-own-delivery posture. The vendor subcontracts to Rolls-Royce Corporation for engine and propulsion-related components and services (T108 engine sustainment, Quick Engine Change Assembly logistics support, engine and propeller sustainment labor) and to Lockheed Martin Corporation for C-27J propeller repair and return services and pitch control unit repairs under USASOAC (United States Army Special Operations Aviation Command) contracts, positioning GE Aviation Systems as a prime integrator for propeller system delivery while leveraging specialized engine suppliers.

GE Aviation Systems LLC is a child entity of General Electric Company, a multi-billion-dollar multinational manufacturer of aircraft engines, power systems, and advanced technologies. General Electric holds major indefinite delivery contracts with the Department of Defense including a $5 billion Air Force vehicle for F110 aircraft engines and a $1.128 billion Army contract for T700 series turbine engine production, positioning GE as a strategic supplier for Department of Defense aviation sustainment across engine and propeller propulsion systems. This parent relationship provides GE Aviation Systems LLC access to GE's engineering, manufacturing, and supply-chain infrastructure and positions the subsidiary as a critical node in the larger GE defense aerospace portfolio serving military aircraft platforms globally.
