Safran

As of October 2026 – No aircraft has “Safran” in big letters on the fuselage. And yet you have probably photographed the group thousands of times: every Boeing 737 MAX flies with engines that Safran builds together with GE Aerospace, as do a large part of the A320neo family, all 737 Classics and NGs and many A320ceos. On top of that come helicopter turbines, the Rafale’s engine, landing gear, brakes and passenger seats. That makes Safran perhaps the most important aviation name that many spotters never consciously notice. This profile shows you what is behind it and how to recognize Safran technology in the field.

From Gnome to Safran: over a hundred years of engine building

The name Safran is young, the roots are not. At the beginning stands Gnome, founded in 1905 by Louis Seguin. From 1909 the company builds the Omega rotary engine in series, one of the defining aircraft engines of the pioneer era. The merger with Le Rhône later creates Gnome et Rhône, one of the big French engine builders of the interwar period.

After the Second World War France nationalizes the company. In 1945 this creates Snecma, the Société nationale d’études et de construction de moteurs d’aviation. Its first own jet engine is the Atar, and military engines like the M53 and M88 follow later. Together with Rolls-Royce, Snecma also builds the Olympus 593 of the Concorde. Over the decades further traditional names are added: Hispano-Suiza for gearboxes, Messier-Bugatti for landing gear and brakes, Turbomeca for helicopter turbines and Labinal for onboard electrical systems.

The second strand is Sagem, founded in 1925 by Marcel Môme and later strong in navigation and electronics. On May 11, 2005 Snecma and Sagem merge to form the Safran group. The group is headquartered in Paris. Since 2015 Ross McInnes has chaired the board, and the CEO since 2021 is Olivier Andriès.

In 2016 the subsidiaries consistently take the group name: Snecma becomes Safran Aircraft Engines, Messier-Bugatti-Dowty becomes Safran Landing Systems. Two large acquisitions then change the group’s profile. In 2018 Safran takes control of Zodiac Aerospace and thereby becomes one of the largest suppliers of seats and cabin interiors. In July 2025 Safran completes the purchase of the actuation and flight control business of Collins Aerospace, after the Italian government had long blocked the part around Microtecnica. In return Safran is parting with peripheral businesses: the sale of Safran Passenger Innovations, responsible for inflight entertainment and connectivity, has been completed since January 2026.

Economically things are going well. For 2025 Safran reports adjusted revenue of a good €31.3 billion, almost 15 percent more than the year before. This is driven mainly by the propulsion business and by the spare parts and maintenance business around the CFM56 and LEAP.

CFM International: the heart of the group

When spotters talk about Safran, they almost always mean an engine with CFM lettering. CFM International was founded in 1974 as a joint venture of Snecma and General Electric; today it is owned half each by Safran Aircraft Engines and GE Aerospace. The partners share development and production. For the LEAP, Safran assembles half of the engines in Villaroche southeast of Paris, while the other half is built at GE in the USA.

The first success product is the CFM56. It first entered series service in 1982 in re-engined DC-8s of the Super 70 series, then became the standard engine of the Boeing 737 Classic and NG and one of the two options of the A320ceo family. The A340-300 also flies with four CFM56-5Cs. To this day these engines are an everyday sight at almost every airport – fleets like that of Ryanair consist largely of 737-800s with CFM56-7B. Most recently Ryanair and CFM concluded a long-term service agreement for around 2,000 CFM56 and LEAP engines.

The successor is called LEAP and comes in three variants:

All LEAP versions have a composite fan with 18 blades and a significantly higher bypass ratio than the CFM56. On the LEAP-1A the fan diameter is around 1.98 meters, on the LEAP-1B around 1.76 meters because of the 737’s lower ground clearance. In 2025 CFM delivered over 1,800 LEAPs, around 28 percent more than the year before – a record.

Recognizing Safran engines in the field

For spotters the engine is one of the best identifying features there is. The CFM family makes it comparatively easy for you, because each generation has its own look. The article Identifying engines offers a detailed overview of all manufacturers.

CFM56-3 on the 737 Classic: Because the old 737 sits very low to the ground, the nacelle is flattened at the bottom. Every 737 fan knows this “hamster cheeks” shape. CFM56-7B on the 737 NG: The nacelle is also slightly flattened at the bottom, but looks rounder and larger. If you see a 737-800, you almost always have this engine in front of you.

LEAP-1B on the 737 MAX: The most striking feature is the serrated trailing edge of the nacelle, the so-called chevrons. They reduce noise. In addition there is the engine mounted further forward and higher. Because the 737 MAX 8 and its siblings fly exclusively with the LEAP-1B, the assignment is unambiguous here. How the four 737 generations differ overall is shown in the article Boeing 737 Original, Classic, NG and MAX.

CFM56-5 on the A320ceo: On the classic A320 family you have the choice between the CFM56-5 and the IAE V2500. The CFM nacelle ends earlier, and behind it you see the exhaust cone. The V2500 nacelle, by contrast, reaches almost all the way back.

LEAP-1A on the A320neo: This is where it gets tricky. Both the LEAP-1A and the geared fan from Pratt & Whitney sit in large, round nacelles that immediately set the A320neo and A321neo apart from the ceo. For the exact assignment you usually need the model number or a look at the airline’s fleet data. Details are provided by the article A320neo or ceo?.

Four steps to the right engine

Helicopter turbines: the legacy of Turbomeca

A field of its own is Safran Helicopter Engines. The company was founded on August 29, 1938 as Turbomeca, is based in Bordes near Pau on the edge of the Pyrenees and has belonged to the Snecma group since 2001. If you spot rescue, police or corporate helicopters, you constantly encounter its turbines:

• Arriel – the most-built family, over 12,000 units according to reference works. The Arriel 2D powers the H125 and the H130, two Arriel 2Es the H145. The AS365 Dauphin, AW109 and Sikorsky S-76 also use Arriel versions.
• Arrius – smaller turbines, including in the versions of the H135 designated with “T”.
• Arrano – the newest family. Two Arrano 1As power the H160; the turbine received its certification in 2019.
• Makila – the large turbines of the Super Puma and H225.
• Ardiden, Aneto and RTM322 – for medium and heavy helicopters, the RTM322 in cooperation with Rolls-Royce, for example in the NH90.

Visually, the turbines are mostly hidden under the cowling. Here the helicopter type itself helps above all. How to reliably tell the types apart is explained in the article Identifying helicopter types. The parent page for this is Airbus Helicopters, the largest customer of Safran turbines.

Military: M88, TP400 and more

On the military side the M88 is the best-known Safran product. It powers the Dassault Rafale, two engines per aircraft. It first flew on February 27, 1990 in a Rafale prototype, and the production version has been delivered since 1996. At the 2025 Paris Air Show Safran presented the M88 T-REX, a more powerful development intended for the Rafale F5 version. You can read more about the jet and its manufacturer on the page on Dassault Aviation.

On the TP400-D6, the turboprop of the Airbus A400M, Safran is involved in the Europrop International consortium – together with Rolls-Royce, MTU Aero Engines and ITP Aero. Safran contributes the combustor and high-pressure turbine, among other things, which build on experience with the M88. The eight-blade propellers come from Ratier-Figeac. Four of these engines make the A400M one of the loudest and most impressive subjects at any airshow. Tips for recording are provided by the article Recording engine sound.

Historically, Snecma equipped the Mirage generations with the Atar and later the M53; the Larzac was developed together with Turbomeca for the Alpha Jet. Many of these engines are in museums today.

Landing gear, brakes, nacelles and cabins

Less visible, but no less important, are the equipment divisions. Safran Landing Systems sees itself as the world’s largest landing gear manufacturer. From Vélizy near Paris come, among other things, the main and nose landing gear of the Boeing 787, the main landing gear of the A350 and that of the A400M. The division also supplies wheels and carbon brakes for Airbus and Boeing aircraft. If you are interested in landing gear as an identifying feature, the article Landing gear configurations as an identifying feature is worth reading.

Safran Nacelles builds engine cowlings and thrust reversers, including for the A380. Safran Electrical & Power supplies wiring harnesses and power supply, Safran Transmission Systems the gearboxes in the engine. Safran Electronics & Defense stands for navigation and optronic systems found in civil and military aircraft alike.

Since the Zodiac acquisition Safran has also been one of the big cabin suppliers. Safran Seats builds passenger seats from economy to business class, Safran Cabin galleys, lavatories and overhead bins. If you sit in a holiday flight, there is a good chance you have taken a seat on a Safran seat – from the outside, of course, you can’t tell.

What the type reveals and what it does not

Where to see Safran technology best

The simple answer: at every larger airport. The 737 and A320 family dominate European short- and medium-haul traffic, and a large part of it flies with CFM engines. It gets more interesting where Safran is at home.

At Toulouse-Blagnac Airport, new A320neos with LEAP-1A roll fresh out of final assembly, often still without a customer or with test registrations. The Aeroscopia museum right at the airfield shows Airbus history; from the spot at Aeroscopia you can also see the activity on the runway. More tips are in the article Plane spotting in Toulouse-Blagnac.

The group’s heart lies in the Paris region. At Paris-Charles de Gaulle Airport fleets of Air France with the A320 family and other CFM types land. Every two years Le Bourget Airport becomes the stage for the Paris Air Show, where Safran regularly shows new engines and technologies. The article Paris Air Show at Le Bourget explains how to plan your visit. In the Musée de l’Air et de l’Espace you get close to historic French aircraft and their engines – from the museum grounds you also have the flight operations at the airfield in view.

For helicopter turbines you don’t have to travel to France: H125, H135 and H145 fly in air rescue and police service all over Germany, Austria and Switzerland. You see Rafales with M88 mainly at airshows and exercises.

If you want to compare Safran with the other big propulsion manufacturers, there are separate pages on Rolls-Royce, MTU Aero Engines and Pratt & Whitney. The aircraft side of the equation is covered by Airbus, Boeing and COMAC.

Conclusion

Safran is the quiet giant of European aviation. The group builds no aircraft of its own, but through CFM International supplies the engines for the world’s most-flown short- and medium-haul jets, powers countless helicopters with the Arriel, Arrano and Makila, and sits in the Rafale with the M88. On top of that come landing gear, brakes, nacelles and cabins, which you can’t recognize but fly with in almost every airliner.

For your sightings that means: a look at the nacelle, wingtip and model number is often enough to assign Safran technology reliably. On the 737 MAX the matter is clear right away, on the A320neo the registration helps. And if you ever catch an open RISE engine in flight testing, you have a subject that not many spotters own.
