Key takeaways

  • The Saab 340 is a 30- to 36-seat regional turboprop from Sweden, originally developed together with Fairchild and built from 1983 to 1999.
  • Fastest way to identify it: low wing plus a normal (not T-shaped) tail plus four-blade propellers.
  • You tell it from the larger Saab 2000 by length and propellers: the 2000 is much more stretched and has six-blade propellers.
  • In Scandinavia and Great Britain the type is largely history in passenger service – Loganair retired its Saab 340s in early 2024.
  • In flight plans and tracking apps the type appears as SF34.

Identifying features

Is this really the aircraft type in front of you?

Check off everything that applies to the aircraft you are looking at.

  • Low wing: the wings sit low on the fuselage – unlike the ATR and Dash 8, which are high-wing aircraft
  • Conventional tail: the horizontal stabilizer sits at the rear of the fuselage, not on top of the fin as on a T-tail
  • Two four-blade propellers on slender engine nacelles that extend forward past the wing leading edge
  • Short, rounded fuselage just under 20 m long
  • Main landing gear that retracts into the engine nacelles
  • Large, swept-back fin that runs out into a long dorsal fin

Updated: October 2026 – A small twin with droning four-blade propellers, the wings low on the fuselage, the tail completely conventional at the back: if something like that comes into your viewfinder, it’s worth a second look. It may well be a Saab 340 – an aircraft that shaped regional air travel in Scandinavia and Great Britain for decades and is now a real rarity in central Europe. Here you learn how to identify it with confidence, how to tell it from the Saab 2000 and other turboprops and where you can still find it today.

What is the Saab 340?

The Saab 340 is a twin-engine regional turboprop for 30 to 36 passengers, most commonly with 34 seats. It began as a joint project: in January 1980 the Swedish group Saab and the US manufacturer Fairchild announced a joint feeder aircraft, initially called the SF340. Saab took on the fuselage, fin and final assembly in Linköping, Sweden; Fairchild supplied the wings, horizontal stabilizer and engine nacelles. The work split was roughly 65 to 35.

The first flight took place on January 25, 1983. Already in June 1984 Switzerland’s Crossair took over the first production aircraft – the regional airline from Basel was thus the launch customer and brought the type into central European airspace early on. Fairchild left the program in 1985, after about 40 aircraft had been built jointly. From then on the type was a pure Saab product and was simply called the Saab 340.

By the end of production in 1999, about 459 units had been built, with the last delivery in June 1999. That makes the 340 one of the most successful regional turboprops of its generation. Its bigger brother, the Saab 2000, picked up the concept but remained far rarer. After the 340 and the 2000, Saab withdrew from civil aircraft manufacturing and concentrated on military technology such as the JAS 39 Gripen.

The versions: 340A, 340B and 340B Plus

For spotters the variants are hard to tell apart from the outside. Still, it is worth knowing the differences, because the exact version appears in databases and registers.

Version Built Engine Notes
340A 159 GE CT7-5A2 First production version from 1984
340B 200 GE CT7-9B More powerful engines, wider horizontal stabilizer, more performance in heat and at altitude
340B Plus 100 GE CT7-9B From 1994, active noise and vibration suppression, extended wingtips as standard

The active noise suppression on the 340B Plus works with microphones and anti-noise in the cabin and noticeably lowers the noise level in cruise. Some of the late 340Bs already had this system. On many late aircraft the lavatory also moved from the rear to the front behind the cockpit to create more baggage space.

In addition there are freighter conversions (340AF and 340BF), built since the early 2000s from former passenger aircraft. Smaller cargo airlines use them to fly express freight over short routes – one reason the type keeps turning up even after its withdrawal from scheduled service.

Clarify the version by registration

Whether 340A, 340B or freighter: from the outside often only the registration helps you. With it you find version, year of manufacture and previous owners in registers and databases. How that works is shown in the guide Tracking an aircraft by registration.

The three features that are enough to identify it

At first glance turboprops often look alike. With the Saab 340, though, three observations get you there quickly.

Where is the wing?

The Saab 340 is a low-wing aircraft: the wings attach low on the fuselage. The ATR and Dash 8, common in Europe, have their wings on top of the fuselage instead.

What does the tail look like?

The horizontal stabilizer sits at the rear of the fuselage, below the fin. Many competitors like the Dornier 328 or Embraer Brasilia carry it on top as a T-tail instead.

Count the blades

Four blades per propeller point to the 340. If you see six blades on a much longer fuselage, it is more likely a Saab 2000.

In addition, the fuselage looks short and round, the engine nacelles extend far ahead of the wing leading edge, and the main landing gear disappears into the nacelles when retracted. With a bit of practice, the silhouette on approach is enough for you.

Saab 340 or Saab 2000?

The Saab 2000 is the larger successor to the 340 and follows a similar basic layout as a low-wing aircraft. You can mix the two up mainly in photos with no size reference.

Feature Saab 340 Saab 2000
Length 19.73 m a good 27 m
Seats 30–36 approx. 50
Propellers Four-blade Six-blade
Engine GE CT7 Rolls-Royce AE 2100
Look in profile stubby, rounded long and slender

In a photo the difference shows most clearly in the ratio of fuselage to wing: on the 2000 there are visibly more windows ahead of the wing, and the nose looks longer. The six-blade propellers are easy to count in good light – as long as you don’t expose too fast.

Saab 340, ATR, Dash 8 or Dornier 328?

Among regional turboprops there is a whole series of look-alike candidates. The finder helps you narrow it down in three steps. The post Telling turboprops apart offers a detailed overview of the competitors.

Quick ID: small regional turboprop

Three questions, one estimate. The registration remains the final authority.

Likely

Saab 340

Low wing, conventional tail and four-blade propellers are the typical Saab 340 look. If the fuselage looks very long and you see six blades, check the Saab 2000.

Likely

ATR, Dash 8 or Dornier 328

High wings and a T-tail point to a high-wing aircraft like the ATR 42/72, Dash 8 or Dornier 328. It is not the Saab 340.

Likely

Embraer EMB 120 Brasilia

A low wing with a T-tail and four-blade propellers fits the Brasilia, the Saab 340’s direct competitor from Brazil.

You rule out the high-wing ATR 42-600 and Dash 8-100 immediately by the wing position. Trickier is the Embraer EMB 120 Brasilia: it is also a low-wing aircraft of similar size but carries its horizontal stabilizer on top of the fin. The Dornier 328, in turn, has its wings on top and a T-tail – it has little in common visually with the Saab.

Operators in Scandinavia and Great Britain

For about three decades the Saab 340 was a typical sight at northern European regional airports. Today that has changed dramatically – much of this section is aviation history.

Scandinavia: the home region

In Sweden numerous regional airlines flew the home-built type, including Skyways, Swedair and later NextJet, which ceased operations in 2018. The 340 also operated for a time under the brand of SAS. In Finland Blue1, Finnaviation and Finncomm Airlines, among others, relied on Saab; in Norway smaller companies such as Norving. What they have in common: they no longer fly the type today, and many of them no longer exist.

One reason for the withdrawal is the generational change. Modern turboprops like the ATR 72-600 offer more seats and lower costs per seat, and the supply chain for spare parts for an aircraft that has not been built since 1999 is thinning. How the regional market as a whole has shifted is covered in the post Regional airlines in Europe.

Militarily, Sweden stayed loyal to the type longer: the air force used it as a transport (Tp 100) and above all as the S 100 Argus early warning aircraft with the Erieye radar. As a successor, Sweden ordered the GlobalEye, based on a business jet, in 2022. If you are interested in Swedish aviation history around Saab, the Flygvapenmuseum in Linköping (Swedish Air Force Museum) is a good place to start – Linköping is also where the Saab 340s were assembled.

Great Britain: Loganair and the islands

In Great Britain the 340 was associated above all with Loganair. The Scottish airline flew it from 1999, for a time in the colors of British Airways and later as a Flybe franchise. In 2017 Loganair first showed its own new livery on a Saab 340B freighter. Its base in Glasgow made Glasgow Airport one of the best places for Saab photos in Europe for years.

In January 2024 Loganair retired its last Saab 340s and replaced them with ATR turboprops. The last rotation on January 25, 2024 fell exactly on the 41st anniversary of the Saab 340’s first flight. The airline had already given up the larger Saab 2000 in 2020. Other former British operators included Manx Airlines and – on the Channel Island of Guernsey – Aurigny. At least until the mid-2010s, Cranfield University also used a Saab 340 as a flying laboratory in training.

Fleets change quickly

With such an old type, every retirement or sale can change the picture. Before a targeted trip, check whether an operator currently still uses the Saab 340 – best with the type filter SF34 in a tracking service.

Where the Saab 340 flies today

The center of gravity has moved far away from Europe. The largest operator is Australia’s Rex Regional Express, which had 57 Saab 340s in its fleet in August 2025 and thus runs the world’s largest Saab 340 fleet. Other active aircraft fly in the Americas, among other places, often with cargo and charter companies. According to common reference works, about 250 Saab 340s were still in active service in 2023 – exact current figures vary.

In Europe you only come across the type with a few smaller cargo and charter operators. In Germany, Austria and Switzerland it is therefore a real rarity that turns up more by chance at regional airports or on cargo aprons. How to put such lucky finds in perspective is explained in the post How rare is my sighting?.

Region Chance of a hit Why
Australia high Rex operates the world’s largest Saab 340 fleet
Scandinavia low Passenger operators have largely disappeared
Great Britain low Loganair retired the type in 2024, only isolated aircraft
DACH region very low Sporadic cargo and charter flights, ferry flights

A brief look at the history

The Saab 340 did not only see successes. Besides launch customer Crossair, which used the type intensively from Zurich Airport and Basel, KLM Cityhopper also flew the 340 in the 1990s. Both airlines had fatal accidents that led to intensive investigations, such as the crash of Crossair Flight 498 in 2000 shortly after takeoff in Zurich. Over its entire service life, the type is nonetheless regarded as a solid, robust workhorse that plays to its strengths especially on short runways and in rough weather.

That the 340 still flies in Australia, the Americas and as a freighter more than 25 years after the last delivery speaks for its design.

Photo tips for turboprops like the Saab 340

The Saab 340 is not a big subject, but a rewarding one. The compact shape fits well in the frame, and with turning propellers every shot looks alive.

Don’t freeze the propellers

At very fast shutter speeds the propellers stand still in the frame, as if the engine were off. With a somewhat slower shutter speed and panning you get a nice propeller disc. The guide Photographing propellers explains the details.

Choose a side profile

The combination of low wing and conventional tail shows to best effect in profile or slightly from the front at an angle.

Adjust your focal length

At just under 20 meters long, the 340 is small. At regional airports you can often get closer, but at large airports you need more focal length than for a jet.

Plan the light

With rare visitors especially, every attempt counts. Check beforehand where the sun will be at arrival time so you don’t end up shooting into the light.

Where to stand well at smaller airports is explained in the post Spotting at regional airports. With the sun position planner in Planetrack you see right on the spot map when the light suits your vantage point.

Ready for a rare Saab?

Check off what you have already done.

  • I have found an SF34 in the tracking service or flight plan.
  • I know the expected landing direction.
  • I know where the sun will be at the planned time.
  • I have planned a shutter speed for visible propeller motion.
  • My vantage point is publicly accessible and permitted.

Common mix-ups and how to rule them out

It points to the Saab 340 if …

  • the wings sit low on the fuselage
  • the horizontal stabilizer attaches at the rear of the fuselage
  • you count four blades per propeller
  • the tracking service lists SF34 as the type

Take a closer look if …

  • the fuselage looks conspicuously long – then it could be a Saab 2000
  • you only see the aircraft head-on or in backlight
  • a low-wing aircraft of similar size stands in front of you and you can’t make out the tail – the Brasilia looks similar

It is not a Saab 340 if …

  • the wings sit on top of the fuselage (ATR, Dash 8, Dornier 328)
  • the horizontal stabilizer sits on top of the fin
  • you count six blades per propeller
  • a long radar beam sits on the fuselage – then it is the early warning version

Conclusion

The Saab 340 is a piece of northern European regional aviation history. Low wing, conventional tail and four-blade propellers make it unmistakable once you have internalized the combination. While it has largely disappeared from scheduled service in Scandinavia and Great Britain, it still flies in large numbers in Australia – and in Europe only with a few smaller operators. That makes every sighting here a small highlight.

Quick verdict

Wings low, tail at the back, four blades per propeller: that is the Saab 340. If you want to catch one in the DACH region, rely on a type alert for SF34 and keep your eyes open at regional airports and cargo aprons.

Summary

  • The Saab 340 first flew in January 1983, the launch customer was Switzerland’s Crossair; by 1999 about 459 aircraft were built in the 340A, 340B and 340B Plus versions.
  • For decades it shaped regional air travel in Sweden, Finland, Norway and Great Britain; today hardly any passenger 340s fly there anymore.
  • The largest operator is now Australia’s Rex; in Europe the type only flies with a few smaller operators, often in cargo or special roles.
  • Low-wing design, conventional tail and four-blade propellers reliably distinguish it from the ATR, Dash 8, Dornier 328 and Embraer Brasilia.

Frequently asked questions

What is the ICAO type designator of the Saab 340?

The Saab 340 appears in flight plans and tracking services as SF34. The abbreviation recalls the original designation Saab-Fairchild SF340. The successor, the Saab 2000, has its own code.

Why was the Saab 340 originally called the SF340?

The program started in 1980 as a partnership between Saab and the US manufacturer Fairchild. Fairchild built the wings, tail and engine nacelles, among other things, but left in 1985. After that Saab took over all the work, and the SF340 became the Saab 340.

What is the difference between the Saab 340A, 340B and 340B Plus?

The 340A is the first production version with CT7-5A2 engines. The 340B got more powerful CT7-9B engines and a wider horizontal stabilizer. From 1994 the 340B Plus brought, among other things, active noise and vibration suppression in the cabin and extended wingtips. From the outside the versions are hard to tell apart; the registration brings clarity.

How do I tell the Saab 340 from the Saab 2000?

At a good 27 meters, the Saab 2000 is about seven and a half meters longer and has six-blade propellers instead of the 340’s four blades. In profile the 2000 looks slender and stretched, the 340 rather stubby.

Does the Saab 340 still fly in Great Britain?

Hardly any more in scheduled passenger service. Loganair, for years the best-known British operator, retired its Saab 340s in January 2024 and replaced them with ATRs. A few aircraft are still around in special roles – whether a particular aircraft is still active is best checked via its registration.

Where can I still see a Saab 340 today?

The largest fleet is operated by Australia’s Rex with 57 aircraft (as of August 2025). In Europe the type is found only with a few smaller operators and turns up only sporadically in Germany, Austria and Switzerland. A type alert for SF34 is the most reliable way here.

Are there military versions of the Saab 340?

Yes. The best known is the airborne early warning version with the Erieye radar, designated S 100B or S 100D Argus in Sweden. It carries a long, flat radar beam on the fuselage. In addition, the Swedish Air Force used the type as a transport (Tp 100), and the Japan Coast Guard operates a search and rescue version.
