In 1972, in parallel to the [[MiG-21SMT]] and ST variants, a full overhaul of the MiG-21 airframe was being developed around the new Tumansky R-25 engine, which promised a thrust-to-weight ratio of over 1 on full second-stage afterburner when mated to a lightened MiG-21 airframe. The resulting design was given updated avionics and other modernizations, before entering service as the MiG-21bis, the ultimate culmination of the third-generation Fishbed. The MiG-21bis was quickly adopted in the USSR by both the PVO and the VVS, with one minor difference for the two operators. The PVO-flown MiG-21bis was fitted with a Lazur-M GCI (Ground Controlled Interception) guidance system, whereas the VVS-operated variant had a Polyot-OI instrument landing and guidance system outfitted, with the only visual difference between the two variants being a single small antenna under the forward fuselage. The two variants in export were respectively designated as the [[MiG-21 "Lazur-M" (Germany)|MiG-21bis Lazur-M]] (Fishbed-L) and the [[MiG-21bis-SAU (Germany)|MiG-21bis-SAU]] (Fishbed-N) to differentiate them.

Introduced in [[Update "New Power"]], the MiG-21bis is the ultimate Soviet development of the MiG-21. It looks roughly the same as the [[MiG-21S (R-13-300)|MiG-21S]] and [[MiG-21MF (Germany)|MiG-21MF]], both being third-generation MiG-21 models with search radars, internal [[GSh-23-2 (23 mm)|GSh-23]] cannons, and pronounced fuselage spines. However, the similarities end there, as under the hood, the MiG-21bis is a completely new beast. The most important upgrades are the new addition of the new R-25-300 engine, giving this aircraft exceptional thrust, and easily putting it among the best in terms of thrust-to-weight ratio of its battle rating, beaten only by the [[Mirage 5 (Family)|Kfir family]]. The other major upgrade to the MiG-21bis is its fire control system, which now allows it to not only use the [[R-13M1]] missile, but also the ability to mount the APU-60-2 pylons which can carry twice as many [[R-60M]]s on one hardpoint. All in all, people who enjoyed previous Fishbeds for their incredible dogfight performance, and built upon the mastery of working around both the disadvantages and advantages of the Fishbed airframes, will find this aircraft to be very enjoyable to fly, as what it lacks in BVR and strong missiles at its battle rating, are easily outweighed by the lightened airframe and absurdly powerful engine allowing it to punish most planes that engage it in unconditional close-range dogfighting at low altitude.

The {{PAGENAME}} has absolutely phenomenal acceleration and high-speed performance making it one of the highest-performing aircraft in the game. Firstly, the aircraft is quite fast, being able to reach 1365 km/h IAS on the deck (at low altitudes) before its wings rip - this means that it is usually capable of outrunning most enemies at its rank, such as Phantoms and the Mirage, with the exception of the F-104 Starfighters which can outrun the {{PAGENAME}} by a small margin. Secondly, the aircraft has the fastest overall acceleration of any aircraft in the game, meaning that it can reach its top speed quickly. However, like all other MiG-21s, the {{PAGENAME}} cannot turn well and tends to bleed speed at an alarming rate during turns. Extended dogfights should therefore be avoided, as the {{PAGENAME}} will often end up on the losing side.

The {{PAGENAME}} has above-average acceleration and high-speed performance. Firstly, the aircraft is quite fast, being able to reach 1365 km/h IAS on the deck (at low altitudes) before its wings rip, this translates to above-average level-flight speeds at medium to high altitudes. However, like all other MiG-21s, the {{PAGENAME}}, whilst being able to turn well, it tends to bleed speed at an alarming rate during turns. Extended dogfights should therefore be avoided unless you are absolutely sure you are able to outturn your opponent, as the {{PAGENAME}} will often end up on the losing side.

The {{PAGENAME}} has a strong set of control surfaces including an all-moving tail, which keeps the aircraft responsive up to high speeds (>1,300 km/h). However, be aware that the aircraft has two limiting structural factors: the wings' rip speed and structural G limit. Wings will rip at 1365 km/h IAS, a speed the plane can reach relatively quickly given its phenomenal acceleration. The structural limit of 13G means stronger turns should thus be avoided as there is a risk that they will rip the aircraft's wings.

−
This plane is fairly manoeuvrable at high speeds and since it accelerates quickly and climbs extremely well, it works well as an interceptor (take off, reach around 1,000 km/h, burst climb at a 20-25 degree angle up to 6,000 or 7,000 m and fire on anything that can be sighted) but this method has some risks.
+
The main things to remember about this plane is that it is fairly manoeuvrable at high speeds and it accelerates quickly and climbs pretty well. In a combat situation, you should avoid flying slower than 800 km/h, as your plane loses a significant amount of thrust and manoeuvrability at speeds lower than that.
  
−
First the {{PAGENAME}} is prone being hit by a [[Matra R530E]] or the infamous [[AIM-7E Sparrow|AIM-7]] SARHMs (Semi Active Radar Homing Missiles) that can easily shoot the {{PAGENAME}} down since the plane becomes a brick at higher altitudes.
+
Here's how you would want to use this plane to its advantages depending of the state of the game you're in:
  
−
And sometimes, even if the {{PAGENAME}} succeeds in its interception objective, some enemies will fly in a different path, so they'll easily sneak up behind the {{PAGENAME}} and take it down with missiles if it is high and slow enough.
+
At the beginning, climb at a low angle (around 5-10 degrees) and watch your radar for any enemies flying high, it is recommended you stay at lower altitudes and keep a relatively high speed (between 900 to 1300 km/h) so that you can turn away from an enemy locking you with their radar/shooting a missile at you. If the enemy you have located is isolated/not paying attention, engage it and use either your missiles or gun to engage it. Try not to lose too much speed as your plane relies on it. don't forget to look around for any incoming threat.
  
−
The second way to play this plane is to fly at lower altitudes (below 2,000 m) and engage any targets that are encountered, the risk here is that the {{PAGENAME}} is left vulnerable to high-flying enemies that, again, can easily sneak up and take the {{PAGENAME}} down, so pay attention to the surroundings and avoid getting an IR missile shot up into the engine.
+
Towards the mid or end-game, keep flying fast and avoid wasting speed in turns. Use Boom-N-Run tactics (fly towards a target at high speed, engage them quickly and run away) and assist the team with any problematic enemies. If you find a lonely target you can dogfight with, go for it as long as you don't have any other enemy nearby, as extended dogfights with the MiG-21bis tend to leave it very vulnerable to enemy fire.
  
−
The third, and probably safest, way to play the {{PAGENAME}} is to flank around the main fighting area. Side-climb up to around 4-5 kilometres in the air, making sure to avoid the frequented flight paths so the {{PAGENAME}} does not appear on their radar (additionally, turn off the {{PAGENAME}}' radar during this climb so that the enemies' radar-warning receiver does not pick up the MiG-21's radar as well). Idle around the sides until the main body of the enemy team is spotted and then begin turning towards the battlefield to begin engaging targets. As the {{PAGENAME}} returns, keep an eye for any enemy planes that have a similar idea of flanking around. This scenario usually compose of only one enemy fighter climbing up, which a skilled {{PAGENAME}} pilot can begin engaging in their favor if they have a height advantage. However, if two fighters appears, it is best to break off and move towards the vicinity of allies to help engage.
+
In summary: the MiG-21bis is best used in Boom-N-Run tactics for most of the game unless your target is not very manoeuvrable, then you can turnfight with them.
  
−
A more risky but rewarding playstyle is to use (2 x R-13M-1 and 4 x R-60M) or (4 x R-13M-1) and take advantage of MiG-21's huge climb rate, which in theory, is superior to even the F-4K and F-4M (FG.1 and FGR.2). Radars on most jets can scan ~15 degrees above the horizontal, and by climbing at Mach 0.90-0.95, it is possible to fly above the radar and remain undetected at BVR ranges. At high altitudes, the R-13 can be launched at 3km in a chase and even farther in a dive against lower targets. Although the MiG-21 has a substantial advantage in transonic manoeuvrability, the MiG-21's delta wings cause significant energy bleed in turns as mentioned above. Making high-speed diving attacks is certainly a valid tactic, and fighting from high altitude downwards makes situational awareness easier as most enemies will be at lower altitudes rather than in all directions. This playstyle is most suitable for principled Phantom pilots who are accustomed to maintaining a high energy state.
+
Since your main missiles will usually be R-60Ms, try to fire them relatively close to the enemy (between 2 km to 0.5 km). If you're engaging a target flying at high speeds, the minimum distance of engagement will be < 2 kilometres, if your enemy is farther/flying away, try using R-13M1s instead.
  
 
'''Enemies to beware of:'''
 
'''Enemies to beware of:'''
  
−
* [[F-4 Phantom II (Family)|Phantoms]], particularly [[F-4E]] and [[F-4EJ|EJ]] models: these should be the {{PAGENAME}}' priority targets, F-4Es and F-4EJs are well-known for being extremely versatile and dangerous (even sometimes referred to as the best top tier jets in the game). These planes accelerate quickly, can wield the dangerous [[AIM-9J]] AAMs that are able to pull 20 Gs of overload and can hit targets up to 3 km of range, have access to a large amount of flares and have responsive flight controls. However, a lot of Phantom pilots are overconfident into their planes and will often jump into a dogfight with the {{PAGENAME}}, which is a terrible idea for Phantom pilots. The motto "a slow jet is a dead jet" rings true for most situations, but the {{PAGENAME}} has an ace up its sleeve against Phantoms: better low and high speed manoeuvrability that can sometimes match the Phantom's turn rate! So if a Phantom attempts to dogfight the {{PAGENAME}}, take up the challenge as it'll most likely end up with the Phantom pilots losing. However, only do so if there are allies nearby or if there aren't any enemies nearby or the {{PAGENAME}} may end up getting taken out unexpectedly.
+
* F-16A early (Block 10): Amongst the highest BR enemy you can fight if you're in a maximum downtier. This plane is your absolute nemesis as it can counter you in every way. It flies faster than you, it turns better than you and climbs better than you. If you spot an F-16A Block 10, your best strategy would be to try to destroy it from a surprise angle or team up on it with your teammates to destroy it. If you find yourself being targeted by an F-16A Block 10, try to stay fast and do short periodical vertical manoeuvres to throw its aim off. Don't forget to pre-flare if you're flying too slowly as its AIM-9L missiles can spell doom to you. Try to have teammates back you up in these situations, as it is unlikely you will be able to defeat a F-16A Block 10 in a 1v1 dogfight.
−
* The [[Mirage IIIC]] and the [[J35D|J35D Draken]]: These planes are also serious foes since they out turn everything at their BR (keep in mind that the J35D Draken is more manoeuvrable than the Mirage) so dogfighting them is a death sentence. They're also able to wield deadly missiles, the Draken wields the Swedish license built AIM-9P3s known as [[RB24J]]s and the Mirage has access to the extremely effective [[Matra R550 Magic 1]] that pulls 30 Gs and has a higher top speed than other IR guided missiles. The best thing to do against these planes is to do a zoom-climb to bleed their speed since they have a lower thrust-to-weight ratio than the {{PAGENAME}} and then do oblique turns since they both bleed a ton of speed when turning and have a lower acceleration than the {{PAGENAME}} does. And if they try to fire a missile at the {{PAGENAME}}? Don't worry, pop flares, turn off afterburner, and pull hard.
+
* F-14 (A Early/B): Another nemesis you can frequently encounter, but you can beat it. Its AIM-54 Phoenix missiles can destroy you at extreme ranges if you're not paying attention, if you find yourself in BVR range against a F-14, you can be easy prey to its AIM-7F missiles unless you counter them (either by flying very close to the ground or by notching and chaffing). When engaging in close-quarters fights against a F-14, one should take notice that the F-14 is rather manoeuvrable and can beat the MiG-21bis in a continuous turnfight. The best strategy against a F-14 is to make it lose its speed by doing burst climbs and re-descending upon it when it is at its slowest.
 +
* F-4E: Whilst not being as nimble, a skilled F-4E player can easily destroy you. At BVR ranges, you are prey to the F-4E's radar missiles (as you would with any other enemy) but at close ranges, the F-4E can keep up with you in turns as long as it is flying at medium to high speeds (800-1200 km/h).It is possible to beat an F-4E in a sustained dogfight, just make sure you're alone to do it. Overall, the best strategy again an F-4E is, yet again, to bleed its speed with burst climbs and re-engage when it is at its slowest.

Description

In 1972, in parallel to the MiG-21SMT and ST variants, a full overhaul of the MiG-21 airframe was being developed around the new Tumansky R-25 engine, which promised a thrust-to-weight ratio of over 1 on full second-stage afterburner when mated to a lightened MiG-21 airframe. The resulting design was given updated avionics and other modernizations, before entering service as the MiG-21bis, the ultimate culmination of the third-generation Fishbed. The MiG-21bis was quickly adopted in the USSR by both the PVO and the VVS, with one minor difference for the two operators. The PVO-flown MiG-21bis was fitted with a Lazur-M GCI (Ground Controlled Interception) guidance system, whereas the VVS-operated variant had a Polyot-OI instrument landing and guidance system outfitted, with the only visual difference between the two variants being a single small antenna under the forward fuselage. The two variants in export were respectively designated as the MiG-21bis Lazur-M (Fishbed-L) and the MiG-21bis-SAU (Fishbed-N) to differentiate them.

Introduced in Update "New Power", the MiG-21bis is the ultimate Soviet development of the MiG-21. It looks roughly the same as the MiG-21S and MiG-21MF, both being third-generation MiG-21 models with search radars, internal GSh-23 cannons, and pronounced fuselage spines. However, the similarities end there, as under the hood, the MiG-21bis is a completely new beast. The most important upgrades are the new addition of the new R-25-300 engine, giving this aircraft increased thrust over its older variants. The other major upgrade to the MiG-21bis is its fire control system, which now allows it to not only use the R-13M1 missile, but also the ability to mount the APU-60-2 pylons which can carry twice as many R-60Ms on one hardpoint. All in all, people who enjoyed previous Fishbeds for their incredible dogfight performance, and built upon the mastery of working around both the disadvantages and advantages of the Fishbed airframes, will find this aircraft to be very enjoyable to fly, as what it lacks in BVR and strong missiles at its battle rating, are easily outweighed by the lightened airframe and relatively powerful engine allowing it to punish most planes that engage it in unconditional close-range dogfighting at low altitude, bar some specific planes.

The MiG-21bis has above-average acceleration and high-speed performance. Firstly, the aircraft is quite fast, being able to reach 1365 km/h IAS on the deck (at low altitudes) before its wings rip, this translates to above-average level-flight speeds at medium to high altitudes. However, like all other MiG-21s, the MiG-21bis, whilst being able to turn well, it tends to bleed speed at an alarming rate during turns. Extended dogfights should therefore be avoided unless you are absolutely sure you are able to outturn your opponent, as the MiG-21bis will often end up on the losing side.

Offensive armament

Main article: GSh-23L (23 mm)

The MiG-21bis is armed with:

  • 1 x 23 mm GSh-23L cannon, belly-mounted (250 rpg)
  • 64 x countermeasures

The 23 mm GSh-23L are adequate cannons, firing at a high rate of fire. However, the individual rounds from the cannons have a low stopping power, necessitating many hits on target to destroy them.

Usage in battles

The main things to remember about this plane is that it is fairly manoeuvrable at high speeds and it accelerates quickly and climbs pretty well. In a combat situation, you should avoid flying slower than 800 km/h, as your plane loses a significant amount of thrust and manoeuvrability at speeds lower than that.

Here's how you would want to use this plane to its advantages depending of the state of the game you're in:

At the beginning, climb at a low angle (around 5-10 degrees) and watch your radar for any enemies flying high, it is recommended you stay at lower altitudes and keep a relatively high speed (between 900 to 1300 km/h) so that you can turn away from an enemy locking you with their radar/shooting a missile at you. If the enemy you have located is isolated/not paying attention, engage it and use either your missiles or gun to engage it. Try not to lose too much speed as your plane relies on it. don't forget to look around for any incoming threat.

Towards the mid or end-game, keep flying fast and avoid wasting speed in turns. Use Boom-N-Run tactics (fly towards a target at high speed, engage them quickly and run away) and assist the team with any problematic enemies. If you find a lonely target you can dogfight with, go for it as long as you don't have any other enemy nearby, as extended dogfights with the MiG-21bis tend to leave it very vulnerable to enemy fire.

In summary: the MiG-21bis is best used in Boom-N-Run tactics for most of the game unless your target is not very manoeuvrable, then you can turnfight with them.

Since your main missiles will usually be R-60Ms, try to fire them relatively close to the enemy (between 2 km to 0.5 km). If you're engaging a target flying at high speeds, the minimum distance of engagement will be < 2 kilometres, if your enemy is farther/flying away, try using R-13M1s instead.

Enemies to beware of:

  • F-16A early (Block 10): Amongst the highest BR enemy you can fight if you're in a maximum downtier. This plane is your absolute nemesis as it can counter you in every way. It flies faster than you, it turns better than you and climbs better than you. If you spot an F-16A Block 10, your best strategy would be to try to destroy it from a surprise angle or team up on it with your teammates to destroy it. If you find yourself being targeted by an F-16A Block 10, try to stay fast and do short periodical vertical manoeuvres to throw its aim off. Don't forget to pre-flare if you're flying too slowly as its AIM-9L missiles can spell doom to you. Try to have teammates back you up in these situations, as it is unlikely you will be able to defeat a F-16A Block 10 in a 1v1 dogfight.
  • F-14 (A Early/B): Another nemesis you can frequently encounter, but you can beat it. Its AIM-54 Phoenix missiles can destroy you at extreme ranges if you're not paying attention, if you find yourself in BVR range against a F-14, you can be easy prey to its AIM-7F missiles unless you counter them (either by flying very close to the ground or by notching and chaffing). When engaging in close-quarters fights against a F-14, one should take notice that the F-14 is rather manoeuvrable and can beat the MiG-21bis in a continuous turnfight. The best strategy against a F-14 is to make it lose its speed by doing burst climbs and re-descending upon it when it is at its slowest.
  • F-4E: Whilst not being as nimble, a skilled F-4E player can easily destroy you. At BVR ranges, you are prey to the F-4E's radar missiles (as you would with any other enemy) but at close ranges, the F-4E can keep up with you in turns as long as it is flying at medium to high speeds (800-1200 km/h).It is possible to beat an F-4E in a sustained dogfight, just make sure you're alone to do it. Overall, the best strategy again an F-4E is, yet again, to bleed its speed with burst climbs and re-engage when it is at its slowest.

Radars

The MiG-21bis is equipped with a Sapphire-21 search and tracking radar. The radar is mounted in the nose of the aircraft.

Pros and cons

Pros:

  • Impressive climb rate of 225 m/s, making this plane the second-best top-rank climber behind the F-104S and above the Phantom FGR.2 and FG.1
  • Increased flight performance compared to earlier MiG-21s
  • Excels against both aerial and ground targets
  • Has access to flares that are fired downwards, which means that missiles can be more easily evaded
  • Stunning acceleration
  • Can wield six potent all-aspect R-60M air-to-air missiles
  • Huge thrust to weight ratio

Cons:

  • As all MiG-21s, it tends to bleed speed in turns, though not as much, thanks to the improved engine
  • Vicious rudder lock at speeds above 700 km/h, can be frustrating when trying to get guns on target
  • Pretty bad low speed manoeuvrability
  • Doesn't respond well to wing damage - if a wingtip is lost, landing this plane will be very difficult, and if a wing is lost, the plane should be considered as lost
  • Poor energy retention

History

Devblog

By the late 1960's, the Soviet high command sought to increase the effectiveness of the MiG-21 jet fighter, especially at lower altitudes, while at the same time knowing that this could only be achieved by developing a more powerful engine for it. As a result, in 1971, the order to develop what would essentially become the MiG-21bis was issued by the Soviet high command.

As both the power plant manufacturer - Tumansky - as well as the MiG aircraft design bureau were already working on improvements, this order only officially recognized their work, and as a result, by 1972 the MiG-21bis was ready.

Unlike preceding variants, the MiG-21bis managed to strike a balance between performance and endurance. Additionally, the aircraft was fitted with an improved radar and a systems monitor, which made maintenance substantially easier. Furthermore, the maximum number of missiles the aircraft could carry was increased to six while it also received the option to carry the new R-13M air-to-air missile with increased range, higher G-loading and better seeker tracking over the preceding R-3S. Very manoeuvrable R-60M missiles can be carried as well.

The first MiG-21bis was constructed in 1972 and was adopted into service in the same year. Well over 2,200 units of the MiG-21bis would be manufactured, including licence-built versions. The MiG-21bis was one of the most widely produced variants of the aircraft and saw widespread use with numerous operators around the globe. In fact, some modernized modifications are still in combat use today.
