The J29A Tunnan is a single-engine jet fighter developed by SAAB in the late 1940s. One of the main design features of this aircraft is its swept-back wings, which were designed after SAAB acquired German documents from the war that proved that swept-back wings were necessary when trying to achieve higher speeds. The J29A also features a Swedish license-built version of the British de Havilland Ghost engine. The armament consists of four 20 mm akan m/47C, a license-built copy of the British Hispano Mk V, but with a lower rate of fire. The first prototype flew in 1948, and the aircraft then proceeded to enter service in the Swedish Air Force, Flygvapnet, in 1951. It remained in service until 1962 and never saw any combat use.

Introduced in Update 1.95 "Northern Wind", the J29A has a very different playstyle compared to the preceding J21RA. The J29A relies more on teamwork with other jets, as it is inadequate at accelerating and getting to high speed will take a while compared to a lot of opposing jets it will face. The J29A bleeds speed in turns and will have a hard time regaining that speed, making it more recommended to do hit and run passes on unsuspecting enemies. The J29A can turn well when having speed, so it is not atrocious at turning for dogfighting, but prolonged dogfighting puts the aircraft in danger. Being armed with four Akan m/47C 20 mm cannons, the J29A has greater firepower the J21RA, with plenty of ammo to compensate for poorly aimed shots.

The stout little J29A is a sneaky little fighter which might be underestimated during a head-on. A 64 mm bulletproof windscreen is in place, which, since it is sloped, provides 165 mm total protection, allowing the pilot to have a greater chance of survival in a head-on. However, unless highly experienced, pilots should avoid head-ons, especially against aircraft such as the Super Mystere B2 and the G.91 YS which also feature 30 mm DEFA 552 cannons. Make sure to avoid the B2 as well, as the AA.20 air-to-air guided rockets will make the J29A have a hard time standing up to this aircraft.

Offensive armament

Ammunition720 rounds
Fire rate750 shots/min
Main article: Akan m/47C (20 mm)

The J29A is armed with:

  • 4 x 20 mm akan m/47C cannons, nose-mounted (180 rpg = 720 total)

Usage in battles

The J29A, also known as the "flying barrel", is armed with 4 x 20 mm Akan m/47C cannons that perform well, but still lack a bit of a punch for a fighter. The J29A has a good top speed but acceleration is not the quickest. Once it has built up speed it can catch most enemy jets that it will face, but something that will help it greatly in doing so is having an altitude advantage to dive on the target to get that extra acceleration to hunt down targets.

Turning with the J29A is a bad idea since the plane loves to bleed speed when turning, even though the J29A is good at turning, it can only do so for a small amount of time, before losing enough speed to be easy target for incoming enemies. The J29A's strengths are the Hit & Run tactic also known as Boom n Zoom. Should the J29A be uptiered against 8.7, it will struggle to keep up with the enemy jets but that will make the J29A into an excellent support fighter: when allied jets are engaged in combat with the enemy and make that enemy bleed its speed, the J29A can swoop in and help the teammate.

When taking off in RB and Sim modes you must be careful, J29A struggles to get off the runway, spooling, pressuring your front landing gear right before you engage flaps, and using flaps are all essential to a safe takeoff in this plane.

Enemies to be aware of:

When facing these enemies and you see them from distance it's great to take note of any close teammates to help the J29A stand a chance to not be Boom-n-Zoomed, this is why flying with a squadmate that is in a more dogfight-suitable aircraft is highly recommended to make the most out of the J29A, as they will often be able to setup a target for the J29A's Boom-n-Zoom runs.

Pros and cons


  • Decent cannons with plenty of ammunition
  • Can turn well at speed
  • High max speed


  • Inadequate versus its opponents at 8.7 which it faces often
  • Very sluggish acceleration
  • Dumps speed in turns
  • Rudder locks up at higher speeds


Initial development

During WWII, Sweden had effectively fallen behind in the development of military aircraft. This was largely due to a severely underdeveloped aircraft engine industry in Sweden which meant that there were no high-end engines available for aircraft production. Thus Sweden was still projecting propeller-driven fighter aircraft in 1945 equivalent to fighters projected by other nations 1-3 years prior. Since it was obvious by 1945 that jet aircraft was the future the Swedish Air Force decided to immediately scrap all propeller-driven fighter projects and instead make the jump to a jet fighter. Sweden's leading aeronautical firm SAAB, who was already actively working with the Swedish Air Force on the previously mentioned propeller fighters, was tasked with projecting this new jet fighter. Several designs were looked at but by mid-1945 it was decided that a mid-high wing aircraft with a central air intake would be the best option. Due to the mid-high wing it was not possible to house the landing gear in the wings. Instead, it was decided to house the landing gear in the fuselage of the aircraft. This concept got the project name R1001, R standing for "reaktionsmotor" (reaction engine), the Swedish military term for jet engines.

The original specifications for the R1001 called for a radar rangefinder, four Bofors 20 mm akan m/45 cannons mounted in the nose with 180 rounds per gun, external fuel tanks and a top speed of 1,000 km/h. The engine was originally supposed to be an indigenous design by the company STAL but by late 1945 Sweden had gotten the green light for acquiring the new state-of-the-art de Havilland Ghost engine. There are several reasons why Sweden was allowed to buy this engine even before it was finished, but the two main factors were the economic state of Britain after the war and Sweden's good relations with the company de Havilland. The engine was however not the only thing which changed at an early stage. Originally the R1001 featured straight wings, as was common at the time. However, by pure luck Sweden was able to acquire some German WWII research papers from a Swiss source regarding swept wings on aircraft and their increased performance at high speeds. Thus it was decided to change the R1001 design to feature swept wings. The first blueprints of the R1001 featuring swept wings were finished by late 1945 and within 3 years a prototype had been constructed and was ready for flight testing. During these 3 years the design would change even further from the original concept. The radar rangefinder was dropped for unknown reasons, and the Bofors cannons were switched for Hispano designs due to delays at Bofors. By 1947 the aircraft had also received the designation J29.

Testing and production

The J29 prototype flew for the first time on the 1st of September 1948 and immediately showed incredible performance. The pilot chosen for this flight was SAAB's test pilot at the time, an Englishman by the name Robert A. "Bob" Moore. He was a British squadron leader with previous experience flying jets and was thus suitable for the tests. The test flight lasted for half an hour and after a successful landing, Moore stated that "on the ground, it's an ugly duckling, but in the air it's a swift." Like many aircraft which pick up a nickname due to a specific feature or shape, the J29 would fairly quickly receive the nickname "Flygande Tunnan" (The Flying Barrel) or just "Tunnan" (The Barrel) for short. Initially thought of as degrading, the nickname Tunnan would not only become the official name for the aircraft but would also start the SAAB tradition of naming their combat aircraft, a tradition which persists to this day.

After correcting a few production errors the prototype would not only achieve the specified top speed of 1,000 km/h but it would even surpass it, achieving a sustainable speed of 1,060 km/h at one point. The design of the J29 showed a lot of promise for the future and talk of future variants would begin even before production had started. In fact, just a month after the prototype had taken to the air, there was talk of implementing attack rockets and deflatable internal fuel tanks.

Production of the first J29 variant, the J29A, would commence in 1950 and deliveries to the air force would start in early 1951. It was quickly realized that the internal fuel capacity of the J29A was too limited and work began on implementing the previously discussed internal deflatable fuel tanks. This would be realized in a new version of the J29, designated J29B, which entered production and service in 1953. The J29B's new internal fuel tanks gave it a 50% increase in fuel capacity compared to the J29A. The J29B would be followed by an unarmed reconnaissance version called the S29C which had been planned at an early stage. The S29C was to be followed by the J29D, featuring increased armament and an afterburner, but due to a variety of reasons, the J29D never entered production. Instead, a modified version of the J29B, called the J29E, would enter service. The E-variant featured a new dog toothed wing which increased manoeuvrability at high speeds. The J29E was soon followed by the J29F which was an upgrade-program for 210 J29B and E aircraft, increasing their performance and allowing them to serve throughout the 1960s.

All in all, 661 J29s would be produced for the Swedish Air Force, the largest production run by SAAB ever. The last of these would serve until the late 1970s.


The J29 was a truly historical wonder for its time. After being stranded for the duration of the war, Sweden managed to not only catch up with modern aircraft development in a short amount of time but it was also able to lead jet fighter development in Europe for the time and arguably even into modern times. The J29 was the first swept-wing jet fighter to be mass-produced in Europe and together with the Soviet MiG-15 and American F-86 it set the bar for how the next generation of fighter aircraft should be. It was extremely fast for its time and actually managed to take home two closed-circuit world speed records during the mid 1950s.

Besides its international legacy, the J29 was the first Swedish-designed aircraft to see combat. In September 1961, as part of the Congo-crisis, five J29Bs were stationed in the Republic of Congo to contribute to a UN peacekeeping mission (ONUC) in the region. This led to the formation of the air wing F 22 which exclusively served in Congo. F 22 was later reinforced by four more J29Bs and two S29C reconnaissance planes in 1962. F 22 would quickly take air superiority in the area which in turn lead to them primarily performing attack-missions during the conflict. No aircraft were lost during the ONUC despite large amounts of ground fire. When the ONUC was terminated in 1964, the aircraft-type had been decommissioned in Sweden and thus it was decided to only send home a select few J29s to Sweden. The majority of the F 22 J29s were blown up on the spot in Congo when the Swedish left the area.


Between 1950 and 1953 SAAB would produce 224 J29As. These were delivered to the Swedish Air Force between the 10th of May 1951 and the 22nd of April 1953 and would come to serve in the Swedish Air Force until the early 1960s.

As mentioned previously it lacked the internal deflatable fuel tanks that were fitted to the later models and thus had a fairly limited range. It could however equip two underwing drop tanks weighing up to 600 kg each. This increased the range to acceptable levels. Interestingly, the drop tanks could also be armed as incendiary bombs via a switch box in the cockpit. Beyond drop tanks, the aircraft were also capable of carrying a wide variety of rockets for different missions.

The J29A came to serve in the Swedish Air Force until late 1962 when they were taken out of service. Decommissioned J29As were either scrapped or used as shooting targets. One J29A survives to this day and is owned by the Swedish Air Force museum.
