General Electric Co. (GE)

General Electric Company now operates as GE Aerospace and makes jet engines. It designs, builds and then services them, and the servicing is the larger half: an installed base of approximately 50,000 commercial and 30,000 military engines, counting parked aircraft as well as those flying, supports an aftermarket worth approximately 70 percent of what the company takes in. Customers sit in approximately 120 countries. Manufacturing and service happen at 70 facilities across 23 states and Puerto Rico, 24 of them owned, and at 62 facilities in 23 other countries, 30 of them owned. Offices are at 1 Neumann Way, Evendale, Ohio, with executive offices in Washington and Norwalk, Connecticut. FLIGHT DECK is the company's own lean operating model, which it describes as the way it prioritises safety, quality, delivery and cost. There are two reportable segments.

Commercial Engines and Services

This segment designs, makes and services jet engines for commercial aircraft, business aviation and aeroderivative uses, and was approximately 73 percent of company sales in 2025, services three quarters of that. Services mean maintenance, repair and overhaul plus spare parts, sold under long-term service agreements, spare parts agreements or time-and-materials contracts. Customers are airframers and airlines, Boeing and Airbus among them, and third-party overhaul shops that buy spares and licence the repair technology. The engines power narrowbody, widebody and regional aircraft, including those sold through joint ventures, the largest being CFM International, a 50-50 unconsolidated joint venture with Safran Aircraft Engines. Depending on the aircraft, an airline may choose between GE and another maker, and on some Boeing models a GE engine is the only option.

The engine cycle

Engine programmes run over decades: development is long, and an engine then stays in service for years. On narrowbody aircraft the LEAP engine, in service since 2016, is being ramped up, and the company says it expects LEAP to overtake the mature CFM56 as the industry's largest fleet and to bring a matching rise in shop visits. On widebody aircraft the platforms sit at different ages, from the older CF6 and GE90 to the GEnx, in service since 2011, and the GE9X, which powers the Boeing 777X. Development work reported for 2025 includes the GEnx high-pressure turbine blade passing 4,000 cycles in November, with time on wing improved over 2.5 times in hot and harsh conditions, a second dust ingestion test on the GE9X after more than 30,000 test cycles, and CFM International's RISE programme, covering an open fan, a compact core and hybrid electric systems with more than 350 tests completed.

Defense and Propulsion Technologies

This segment was approximately 23 percent of company sales in 2025, with services about half of it, and holds two businesses. Defense and Systems makes and services jet engines, avionics and power systems for governments, militaries and airframers, with platforms including the F110, F404 and F414 combat engines, the T408, T700 and T901 rotorcraft engines and the LM2500 for mobility and marine use; the T901 flew on a Black Hawk for the first time in 2025. The company also works with government customers on classified and unclassified programmes covering combat engines, hypersonics and uncrewed aircraft.

Propulsion and Additive Technologies

The second half of that segment supplies components and systems to commercial and military users under the Avio Aero, Unison, Dowty Propellers and Colibrium Additive brands: small turboprop engines, aeroengine transmissions, turbines, combustors and controls, additive manufacturing, propellers, ignition systems, sensors and engine accessories. Avio Aero is the propulsion partner for the Italian Ministry of Defence, contributing to the EJ200 engine for the Eurofighter, the new Global Combat Air Programme engine and the Catalyst engine for Eurodrone, and is a core funding member of Clean Aviation on the commercial side.

Spending, supply and the name

Research and development came to $2,989 million in 2025, of which the company funded $1,580 million and customers and partners, primarily the United States government, funded $1,409 million. Supply runs through a global chain for raw materials, components, parts and overhaul services; some suppliers are sole or limited source, some procurement rules restrict which can be used, and the filing states the company operates in a supply-constrained environment that has affected the industry for several years. Competition comes from other global engine makers, from third-party overhaul shops in services, and from American and other companies bidding for government contracts. The GE name and logo are licensed to former businesses, including GE HealthCare and GE Vernova.
