Born out of Sweden's need to catch up after WWII, the SAAB J29 emerged as a technological marvel. Designed in just a few years, it incorporated swept wings (acquired from German research) and a powerful British engine, becoming the first mass-produced jet fighter with this configuration in Europe. The A29B variant, essentially a J29 variant initially used for attack missions due to delays in a dedicated attack aircraft, played a key role in this early jet development story. The aircraft was also fitted with internal deflatable fuel tanks that give this fighter more flexible fuel options when compared to the [[J29A]].

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish jet fighter {{Battle-rating}}. It was introduced in [[Update 1.95 "Northern Wind"]].
+
It was introduced in [[Update 1.95 "Northern Wind"]]. When it comes to armament, the A29B is identical to the J29A except for the addition of powerful rockets (without a ballistics computer), making it a force to be reckoned with in ground battles both in CAP and CAS applications. Since it is a conversion of a fighter for ground attack missions, it has very capable flight performance without ordnance. A good strategy to use in grounds battles would be launching your rockets on easy targets before quickly changing your focus to air superiority, racking up points and helping your team against enemy CAS.

The stout little {{PAGENAME}} 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 {{PAGENAME}} have a hard time standing up to this aircraft.

The {{PAGENAME}} is armed with 4 x 20 mm Akan m/47C cannons, but still lack a bit of a punch for a fighter. The {{PAGENAME}} has a good top speed but its acceleration is not the quickest. Once it has built up speed it can catch most enemy jets that it will face, but having an altitude advantage to dive on the target will help get that extra acceleration to hunt down targets.
  
−
=== Manual Engine Control ===
+
Turning with the {{PAGENAME}} is a bad idea since the plane bleeds speed when turning. Even though the {{PAGENAME}} 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 {{PAGENAME}}'s strengths are the Hit & Run tactic also known as Boom & Run. Should the {{PAGENAME}} be uptiered against 8.7, it will struggle to keep up with the enemy jets but that will make the {{PAGENAME}} an excellent support fighter: when Allied jets are engaged in combat with the enemy and make that enemy bleed its speed, the {{PAGENAME}} can swoop in and help the teammate.

=== 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 British "in development" de Havilland Ghost engine. There are several reasons why Sweden was allowed to buy this new powerful 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 Englishmen 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.
 +
 
 +
=== Legacy ===
 +
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-86A-5|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.

As mentioned previously the J29B was fitted with new internal deflatable fuel tanks and these were located in the inner wings. This gave the J29Bs ~50% more fuel than its older brother the J29A. The J29B could also equip two under wing drop tanks weighing up to 600 kg each, which increased the range even further. 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.

Description

Born out of Sweden's need to catch up after WWII, the SAAB J29 emerged as a technological marvel. Designed in just a few years, it incorporated swept wings (acquired from German research) and a powerful British engine, becoming the first mass-produced jet fighter with this configuration in Europe. The A29B variant, essentially a J29 variant initially used for attack missions due to delays in a dedicated attack aircraft, played a key role in this early jet development story. The aircraft was also fitted with internal deflatable fuel tanks that give this fighter more flexible fuel options when compared to the J29A.

It was introduced in Update 1.95 "Northern Wind". When it comes to armament, the A29B is identical to the J29A except for the addition of powerful rockets (without a ballistics computer), making it a force to be reckoned with in ground battles both in CAP and CAS applications. Since it is a conversion of a fighter for ground attack missions, it has very capable flight performance without ordnance. A good strategy to use in grounds battles would be launching your rockets on easy targets before quickly changing your focus to air superiority, racking up points and helping your team against enemy CAS.

The stout little A29B 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 A29B have a hard time standing up to this aircraft.

Armaments

Offensive armament

Main article: Akan m/47C (20 mm)

The A29B is armed with:

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

Suspended armament

Main articles: srak m/55 Frida, psrak m/49A, srak m/51, hprak m/49

The A29B can be outfitted with the following ordnance:

  • Without load
  • 24 x 7,5 cm srak m/55 Frida rockets
  • 14 x 14,5 cm psrak m/49A rockets
  • 14 x 15 cm srak m/51 rockets
  • 4 x 18 cm hprak m/49 rockets

Usage in battles

The A29B is armed with 4 x 20 mm Akan m/47C cannons, but still lack a bit of a punch for a fighter. The A29B has a good top speed but its acceleration is not the quickest. Once it has built up speed it can catch most enemy jets that it will face, but having an altitude advantage to dive on the target will help get that extra acceleration to hunt down targets.

Turning with the A29B is a bad idea since the plane bleeds speed when turning. Even though the A29B 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 A29B's strengths are the Hit & Run tactic also known as Boom & Run. Should the A29B be uptiered against 8.7, it will struggle to keep up with the enemy jets but that will make the A29B an excellent support fighter: when Allied jets are engaged in combat with the enemy and make that enemy bleed its speed, the A29B can swoop in and help the teammate.

When taking off with ordnance in RB and Sim modes you must be careful, the A29B struggles to get off the runway; spooling, pressuring your front landing gear right before you engage flaps, and using flaps are all essential for a safe takeoff in this plane.

Pros and cons

Pros:

  • High speed in a straight line.
  • Powerful cannons with decent ammunition pool and access to very good AA belts.
  • Good ordnance selection for ground attack.
  • Effective flaps.
  • Great turning ability at speed.
  • Good roll rate.
  • High quantity of rockets which launch individually.

Cons:

  • Slow acceleration.
  • Slow climb rate.
  • Ineffective Airbrake
  • Relatively large target in Ground Battles for SPAA.
  • Struggles to get off the runway with some loads.
  • Extremely sluggish turning capability at low speed. Will dump speed when turning also.

History

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 British "in development" de Havilland Ghost engine. There are several reasons why Sweden was allowed to buy this new powerful 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 Englishmen 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.

Legacy

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.

A29B

Between 1953 and 1955, SAAB would produce and deliver 361 J29Bs to the Swedish air force. These would come to serve in the Swedish air force up until the early 1960s.

As mentioned previously the J29B was fitted with new internal deflatable fuel tanks and these were located in the inner wings. This gave the J29Bs ~50% more fuel than its older brother the J29A. The J29B could also equip two under wing drop tanks weighing up to 600 kg each, which increased the range even further. 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.

Due to delays with the A32A-development, the J29B would initially serve as an attack aircraft, being designated as the A29B. While rockets were available for the J29A it was decided to use the J29B as an attack aircraft due to it being a new aircraft type which could be sent directly to the attack wings.
