Jet and Aircraft Engine Manufacturers

Four companies build the engines on nearly every airliner flying today: GE Aerospace, Rolls-Royce, Pratt & Whitney and Safran. Two of them do most of that work through a joint venture, CFM International, whose LEAP and CFM56 engines power the Boeing 737 and most Airbus A320s. Below the big four sit a second tier of turboprop, business jet and helicopter engine makers, the piston engine builders behind most training aircraft, a handful of APU specialists, and a small group of electric and hydrogen powertrain developers, one of which holds the first EASA certificate for an electric motor for new air mobility.

This guide lists them all, with headquarters, main engine families and the aircraft each one powers, and links to their pages in our directory. You can also browse all manufacturers and aircraft parts suppliers. Engine data is taken from the manufacturers' own sites and public certification records as of 26 October 2026. If you are looking for the companies that build the aircraft themselves, see our guide to aircraft manufacturers by country.

The big four

GE Aerospace

GE Aerospace (Evendale, Ohio) became a standalone company in April 2024 when the old General Electric split in three. It has the largest installed base of commercial engines in the world, counting its CFM joint venture. Its own wide-body engines are the GE90 (Boeing 777-200LR and 777-300ER), the GEnx (787 and 747-8) and the GE9X, the most powerful jet engine certified. It will power the 777X, whose first delivery Boeing now expects in 2027. The CF34 powers Bombardier CRJs, first-generation Embraer E-Jets and the Challenger 600 series. The Passport powers the Bombardier Global 7500 and 8000.

In turboprops, the Catalyst, developed largely at GE's Avio Aero unit in Italy, received FAA certification in February 2025 and is the engine of the Beechcraft Denali. The Denali is still in flight testing, and Textron expects it to enter service in 2027. Military engines include the F110 (F-16) and F414 (F/A-18E/F, Gripen E).

Rolls-Royce

Rolls-Royce Holdings is headquartered in London; its civil engines are built in Derby, England, and business jet engines at Rolls-Royce Deutschland in Dahlewitz, near Berlin. Its Trent family is the only choice on the Airbus A350 (Trent XWB) and A330neo (Trent 7000), one of two options on the 787 (Trent 1000) and one of two on the A380 (Trent 900), which is no longer built. Rolls-Royce no longer competes for narrow-body airliners, having sold its share of IAE in 2012; its UltraFan demonstrator, run in 2023, is intended to bring it back into that market in the 2030s.

For business aviation the Pearl 15 powers the Bombardier Global 5500 and 6500, the Pearl 700 the Gulfstream G700 and G800, and the Pearl 10X will power the Dassault Falcon 10X. The AE 3007 powers Embraer ERJ 145s, the Cessna Citation X and the RQ-4 Global Hawk, and the AE 2100 turboprop powers the C-130J.

Pratt & Whitney

Pratt & Whitney (East Hartford, Connecticut) is part of RTX. Its main commercial product is the PW1000G geared turbofan, usually called the GTF, in which a gearbox lets the fan turn more slowly than the turbine. The variants and the aircraft they power:

• PW1100G-JM: Airbus A320neo family, in service since January 2016, in competition with the CFM LEAP-1A
• PW1500G: Airbus A220, sole engine
• PW1900G: Embraer E190-E2 and E195-E2, sole engine
• PW1700G: Embraer E175-E2 (aircraft not yet in service)
• PW1200G: Mitsubishi SpaceJet, cancelled with the aircraft in 2023
• PW1400G: Yakovlev MC-21, replaced by the Russian PD-14 after sanctions

The GTF has had a difficult first decade. A powder-metal contamination problem found in 2023 forced accelerated inspections that grounded hundreds of A320neo-family aircraft at a time. An upgraded version, the GTF Advantage, with higher thrust and longer time on wing, was certified by the FAA in February 2025 and validated by EASA in October 2025. EASA approved the A320neo family with the Advantage in April 2026. Pratt & Whitney expects the Advantage to become the production standard by 2028. Older Pratt engines such as the PW4000 and PW2000 remain in wide use on 777s, 767s and 757s. Military engines include the F135 (F-35) and F119 (F-22).

Safran

Safran (Paris) is France's engine and aerospace group. Safran Aircraft Engines is GE's equal partner in CFM International and builds the M88 for the Rafale and, through the Europrop consortium with Rolls-Royce, MTU and ITP Aero, the TP400 for the A400M. Safran Electrical & Power received EASA certification for the ENGINeUS 100, the first electric motor certified for new air mobility, in early 2025 (see the electric section below). Safran Helicopter Engines, based in Bordes in south-west France, is covered under helicopters.

The joint ventures: CFM and IAE

CFM International is a 50/50 company of GE Aerospace and Safran Aircraft Engines, with offices in Cincinnati and near Paris. GE builds the core and Safran the fan and low-pressure turbine. The CFM56, delivered since 1982 and now built only in small numbers, powers the Boeing 737 Classic and 737NG, most Airbus A320ceo-family aircraft, the A340-200/300 and the KC-135R. Its successor, the LEAP, is the sole engine of the 737 MAX (LEAP-1B) and the COMAC C919 (LEAP-1C), and has the larger share of A320neo orders against the GTF (LEAP-1A). CFM is also maturing its RISE open-fan technology for a future narrow-body engine, and says ground and flight tests will come before 2030.

International Aero Engines (IAE) is owned by Pratt & Whitney, Japanese Aero Engines Corporation and MTU Aero Engines. Its V2500 powers a large share of A320ceo-family aircraft, plus the MD-90 and the Embraer C-390 Millennium. Production for airliners has ended, but the C-390 keeps the line open, and many engines remain in service.

MTU Aero Engines (Munich) builds no complete commercial engine of its own but is a risk-sharing partner on the GTF, V2500, GEnx and GE9X, and a partner in the EJ200 and TP400 consortia. ITP Aero (Zamudio, Spain) builds low-pressure turbines for the Trent family. Korea's Hanwha Aerospace builds F404 and F414 engines under licence.

Turboprop engine manufacturers

Pratt & Whitney Canada (Longueuil, Quebec) has a world mandate within P&W for small and medium engines and is the dominant maker of turboprops. The PT6A, in production since the 1960s, powers the Beechcraft King Air, Cessna Caravan, Pilatus PC-12, Daher TBM and Kodiak, DHC-6 Twin Otter, Piper M500 and M600, and the T-6 Texan II and PC-21 trainers. The PW100 series powers the ATR 42 and 72 (PW127, now the PW127XT), Dash 8-100 to -300, and the PW150A the Dash 8-400. P&WC's turbofans also power many business jets, including the Phenom 100 and 300, Falcon 2000 and 6X and Gulfstream G500 and G600.

GE Aerospace is P&WC's main challenger with the Catalyst (Denali). Honeywell's TPE331 still powers the MQ-9 Reaper and Dornier 228, and the Europrop TP400, the most powerful turboprop in Western service, powers the A400M.

Business jet and regional engines

Honeywell Aerospace (Phoenix, Arizona) became an independent company on 29 June 2026, when it was spun off from Honeywell and began trading on Nasdaq (ticker HONA). Its HTF7000 family powers the Bombardier Challenger 300, 350 and 3500, Embraer Legacy 450/500 and Praetor 500/600, Gulfstream G280 and Cessna Citation Longitude. The TFE731, in service since 1972, is on the Learjet 70/75 and Falcon 900.

Williams International (Pontiac, Michigan, with its factory in Ogden, Utah) builds the FJ44, the engine on the Cessna Citation M2, CJ3+ and CJ4, the Pilatus PC-24, and the smaller FJ33 on the Cirrus Vision Jet.

Helicopter engine manufacturers

Safran Helicopter Engines (Bordes, France) is the largest. The Arriel powers the Airbus H125 and H130, the Arrius the H135, the Arrano the H160 and the Makila the H225. GE Aerospace's T700 and civil CT7 power the UH-60 Black Hawk and AH-64 Apache. Pratt & Whitney Canada's PT6C and PW200 series are on the AW139, Bell 412 and H135, and Rolls-Royce's M250 and RR300 power the Bell 407 and Robinson R66. Honeywell's T55 powers the CH-47 Chinook.

Piston engine manufacturers

Most training aircraft and light singles use air-cooled piston engines from two US companies. Lycoming Engines (Williamsport, Pennsylvania), part of Textron, builds the O-320, IO-360, IO-390 and IO-540 families found in the Cessna 172 and 182, Piper Archer and Seminole, Cirrus SR20, Robinson R22 and R44 and most Van's RVs.

Continental Aerospace Technologies (Mobile, Alabama), owned by China's AVIC since 2011, builds the IO-550 for the Cirrus SR22, Beechcraft Bonanza and Baron, the TSIO-360 for the Piper Seneca and jet-fuel diesels used in the Diamond DA40 and DA42.

Rotax Aircraft Engines (BRP-Rotax, Gunskirchen, Austria) builds the 912, 915 iS and 916 iS liquid-cooled engines that power the majority of light-sport and ultralight aircraft in Europe, including Tecnam, Pipistrel, BRM Aero and Flight Design types and the Tecnam P2006T twin.

Austro Engine (Wiener Neustadt, Austria), owned by Diamond Aircraft, builds the AE300 and AE330 jet-fuel engines for the DA40 NG, DA42-VI and DA62. Jabiru (Bundaberg, Australia) builds its own 2200 and 3300 engines.

APU manufacturers

An auxiliary power unit is a small gas turbine, usually in the tail, that supplies electrical power and air on the ground and in flight.

Honeywell is the largest. Its 131-9 family is standard on the 737NG and 737 MAX and on most A320-family aircraft; the 331-500 is on the 777, the HGT1700 on the A350 and the RE220 and 36-150 series on business jets and regional aircraft. Pratt & Whitney (through the former Hamilton Sundstrand and P&WC lines) builds the APS3200 for the A320 family, the APS5000 for the 787, the APS2300 for Embraer E-Jets and the PW980 for the A380. Safran Power Units (Toulouse) supplies APUs for business jets and helicopters.

Engine makers in China, Russia and Ukraine

Aero Engine Corporation of China (AECC, Beijing) builds the WS-10 for the J-10, J-16 and J-20 and the WS-20 for the Y-20 transport, and is developing the CJ-1000A as a domestic alternative to the LEAP-1C on the C919. Russia's United Engine Corporation (Rostec) builds the PD-14 for the MC-21, the PD-8 for the SJ-100 and the PS-90A for the Il-76 and Il-96; it is under Western sanctions. Ukraine's Ivchenko-Progress designs, and Motor Sich in Zaporizhzhia builds, the D-18T (An-124) and D-436 engines.

Electric and hydrogen propulsion

The first certified electric aircraft engine was the Pipistrel E-811, approved by EASA in 2020 for the Pipistrel Velis Electro. Safran Electrical & Power's ENGINeUS 100, a 125 kW motor, became in early 2025 the first electric motor certified by EASA for new air mobility; it has been chosen by Diamond (eDA40), Aura Aero and Electra.

magniX (Everett, Washington) builds the magni350 and magni650 motors flown on a Harbour Air DHC-2 Beaver and a Cessna Grand Caravan. ZeroAvia (United States and United Kingdom) is developing the ZA600 hydrogen-electric powertrain for 9 to 19-seat aircraft. H55 (Sion, Switzerland), a spin-off of the Solar Impulse project, builds battery packs and electric propulsion for trainers, and Beta Technologies (Burlington, Vermont) makes its own motors alongside its Alia aircraft. Among the majors, GE Aerospace and Pratt & Whitney are working on hybrid-electric demonstrators, CFM on the RISE open fan, and Airbus delayed its ZEROe hydrogen airliner in 2025.

Questions people ask about aircraft engine manufacturers

Who makes the most jet engines?

CFM International, by number of engines in airline service, because it is the sole supplier on the 737 and the larger of two on the A320 family. Counting CFM's half, GE Aerospace has the largest installed base of any single company.

What is the biggest jet engine?

The GE9X for the Boeing 777X. Its fan is 134 inches (3.4 metres) across. It is the most powerful jet engine certified.

Who makes the PW1100G?

Pratt & Whitney, with MTU Aero Engines and Japanese Aero Engines Corporation as partners. It is the A320neo version of the PW1000G geared turbofan; the A220 and Embraer E2 use the PW1500G and PW1900G variants.

Does Boeing or Airbus make its own engines?

No. Neither airframer builds engines; both source engines from GE, CFM, Rolls-Royce and Pratt & Whitney. Airlines usually choose the engine when they order the aircraft, where there is a choice.
