The {{PAGENAME}} is a highly manoeuvrable plane, with a good climb rate. The guns, although a downgrade compared to the 13.2 mm MGs from the previous propeller-driven version, still provide enough firepower to down most targets efficiently. The {{PAGENAME}} is also the first to feature the iconic "Paddan" gunpod, giving it additional lead downrange. Along with central-mounted rockets, the plane is comfortable in both Air Realistic and Ground Realistic battles. The only downside is the airframe, which prevents the aircraft from reaching higher speeds. This is due to the engine being a bit too powerful for the plane, making it common to rip in straight lines and shallow dives.
 
−
 
−
The plane is an overall great introduction for anyone looking to learn to fly jet aircraft, as the vehicle handles very similar to its propeller-driven counterpart, while at a much higher speed than before.

The A21RB is a very manoeuvrable jet with a good climb rate for an early jet. The guns, although a downgrade from the previous propeller-driven version of the plane provides enough firepower to down targets efficiently unless a snapshot is required. It does however have a very low rip speed, preventing you from diving on or chasing most of the opponents you'll be facing. Mounting rockets increases your drag by a huge amount, reducing your top speed by several hundred km/h while making you almost unable to climb.
  
−
The {{PAGENAME}} is distinctly different in looks and performance from all other planes found at the same BR-range. Along with the Yak-15, the Saab 21R is one of the two propeller-driven planes successfully converted into jet propulsion. Just like its Soviet counterpart, the solution comes at the cost of speed. Although a lot more powerful than the A21A-3, it still has the same airframe limitations. The climb-rate is also significantly improved due to the weight of the vehicle, resulting in good vertical energy with the ability to stall out slower opponents. Getting back down can prove difficult however, as the {{PAGENAME}} has a rip speed of just 787 km/h, which it can accidentally reach if not careful. To avoid this, the plane features a small set of air-brakes, which aids in maintaining a safe speed. Experienced pilots can find a good use for them to force overshoots, or to out-turn propeller-driven opponents. Be careful with the engine however! The propulsion of the {{PAGENAME}} is very primitive, and suffers from fuel starvation during extreme manoeuvres, especially in negative G-loads. This can be fatal when fighting vertically, as the engine drops all power almost immediately, and has to spool back up again before reaching the same efficiency as before.

Although the {{PAGENAME}} is meant for ground-attack, the plane lacks significant protection to withstand a lot of incoming fire. The pilot is well protected by metal plates and bulletproof glass, but the pilot's safety isn't the primary concern for the {{PAGENAME}}, as the tail section is incredibly vulnerable. This is due to the twin-boom design, making a tailstrike twice as likely. And since the tail connects to the wing-section, the plane tends to lose tail-control when struck by wing damage. The engine is very large in comparison to the rest of the plane, making it a common target. The {{PAGENAME}} should avoid all possible damage, as surviving large amounts of fire is highly unlikely. Pulling away from head-on engagements increases the survivability immensely. Avoiding the enemy airfield is also important, as the {{PAGENAME}} lacks the speed to keep it safe from flak fire.

The {{PAGENAME}} shares the same 20 mm cannon found on the previous [[A21A-3]]. This cannon is near identical to the [[Hispano Mk.V (20 mm)|Hispano Mk.V]], only with a 30 rpm lower fire-rate. The shells perform the same as on all the other 20 mm-armed jets, making it highly devastating against all types of aircraft. The Armoured targets belt performs favourably with this cannon, as the Air targets belt can cause some mishaps during short bursts. The cannon runs out of ammunition quite quickly compared to the machine-guns, so saving it by only making use of the small calibre guns first can be ideal for spraying.
 
−
 
−
The {{PAGENAME}} features .50 cal machine guns, being identical to the later American ones. Although a direct downgrade from the Swedish 13 mm previously found on the plane, the {{PAGENAME}} makes good use of these cannons, as they allow for distanced engagements, along with additional firepower to back up the 20 mm cannon. Their ammo count is quite high as well, making them great for strafing, and finishing off heavy bombers.

A unique feature only found on the {{PAGENAME}} is the ability to use the abstract gunpod. Commonly known as "Paddan" (directly translated to "The toad"), the gunpod features eight 8 mm Ksp m/22, repurposed from old J8 Gladiators. Although weak guns by nature, having eight of them gives the {{PAGENAME}} unprecedented fire-power shredding anything that goes head-to-head with it. The ammunition count is low, however, which forces pilots to use them carefully. Saving the gunpod by only using .50 cal on distant opponents, allows the {{PAGENAME}} to get rid of opponents during short bursts, which can be incredibly useful if mastered correctly. It's still important to mention that this gunpod is incredibly heavy and not very aerodynamic, and thus takes a heavy hit on the overall speed of the plane.
 
−
 
 
−
The {{PAGENAME}} has a lot of additional advantages over the prior A21A-3, especially when it comes to the ground ordnance. The ground rockets are finally mounted in the middle of the plane, firing one at a time starting from the right. Since the Swedish rockets, especially the m/49 rockets, feature amazing ballistics with little inaccuracy, that along with high penetration, makes for some highly effective air-support. And since the {{PAGENAME}} is quite light, it can easily perform several passes on opponents, which is quite important against heavy opponents.

Despite being jet-powered, the {{PAGENAME}} still performs best when played like a propeller driven aircraft. The airplane struggles to reach high speeds, and drops it fairly quickly when manoeuvring. So the best use of the new engine is to gain altitude. Although weak in performance compared to earlier jets, the {{PAGENAME}} is decent at climbing to altitude, and can very efficiently deal with targets thanks to the high agility offered at lower speeds. Although the flaps are designed for much lower speeds (similar to the A21A-3), the plane still performs similar to the propeller variant when turning, making them less desired than on other jets.

The best way to start a match is to immediately gain altitude. A height advantage around 5 km is usually ideal to avoid losing vital speed when fighting, as the plane can simply dive to gain more velocity. The best way to handle opponents, is to single them out from their team, and forcing them to dogfight, as the {{PAGENAME}} is too slow to chase anyone down. The {{PAGENAME}} is also efficient against propeller aircraft, as it can comfortably turn-fight, while keeping a higher speed. When paired with the devastating firepower it provides, the {{PAGENAME}} becomes deadly when used properly.

The {{PAGENAME}} is even more effective in combined battles, as the platform is highly agile, ideal for close and precise rocket attacks. To compliment this, the {{PAGENAME}} features a fantastic rocket placement, in the center of the aircraft. These launch one at a time, similar to other Swedish aircraft. This gives the {{PAGENAME}} 10 single rocket salvos (m/49A), that can effectively kill one tank each when aimed properly. It's ideal to launch each rocket with the crosshair pointed slightly above the target, as they are placed fairly low. A creative pilot could also make use of the much larger m/49 rockets, but these require a lot of compensation in elevation, and are overall much more difficult to make use of.

While playing the {{PAGENAME}} in Ground RB, it's important to still prioritize air targets. The {{PAGENAME}} is still agile, despite carrying suspended armaments, and is even cheaper to spawn with the 8 mm gunpod, which shreds both aircraft and lightly armoured vehicles. Prioritizing aircraft will substantially help both you, and the team below, as they are capable of dealing equally as much damage.

Description

GarageImage A21RB.jpg


The A21RB is a rank V Swedish jet fighter with a battle rating of 6.7 (AB/RB) and 7.0 (SB). It was introduced in Update 1.95 "Northern Wind".

General info

Flight performance

The A21RB is a very manoeuvrable jet with a good climb rate for an early jet. The guns, although a downgrade from the previous propeller-driven version of the plane provides enough firepower to down targets efficiently unless a snapshot is required. It does however have a very low rip speed, preventing you from diving on or chasing most of the opponents you'll be facing. Mounting rockets increases your drag by a huge amount, reducing your top speed by several hundred km/h while making you almost unable to climb.

Armaments

Offensive armament

Main articles: Akan m/45 (20 mm), Akan m/39A (12.7 mm)

The A21RB is armed with:

  • 1 x 20 mm Akan m/45 cannon, nose-mounted (140 rpg)
  • 2 x 12.7 mm Akan m/39A machine guns, nose-mounted (350 rpg = 700 total)
  • 2 x 12.7 mm Akan m/39A machine guns, wing-mounted (325 rpg = 650 total)

Suspended armament

Main articles: m/49, m/49A, m/51, Ksp m/22 (8 mm)

The A21RB can be outfitted with the following ordnance:

  • Without load
  • 8 x 8 mm Ksp m/22 machine guns, belly-mounted (gunpod) (100 rpg = 800 total)
  • 10 x m/49A rockets
  • 10 x m/51 rockets
  • 5 x m/49 rockets

Usage in battles

Describe the tactics of playing in the aircraft, the features of using aircraft in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

II New boosters Compressor Airframe New 20 mm cannons m/49A
III Wings repair Engine Offensive 12 mm New 8 mm MGs m/51
IV G-suit Cover New 12 mm MGs m/49

Pros and cons

Pros:

  • Able to mount very powerful and accurate rockets for ground attack
  • Upgraded engine compared to the comparable J21RA, giving you a better climb rate

Cons:

  • Rocket ramp is rendered as a solid object, reducing your maximum speed by several hundred kph
  • Gun-pod only has 800 rounds in total spread between all guns
  • Extremely low rip speed for a jet, 787 kph
  • 12.7 mm machine-guns instead of the 13.2 mm of the previous propeller-driven version of the plane, severely reducing firepower

History

Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
