Description
The MiG-21bis is a rank VII Soviet jet fighter with a battle rating of 11.0 (AB/RB/SB). It was introduced in Update "New Power".
General info
Flight performance
The MiG-21bis has absolutely phenomenal acceleration and high-speed performance making it one of the strongest 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 tier, such as Phantoms and the Mirage, with the exception of the F-104 Starfighters which can outrun it by a small margin. Secondly, the aircraft has the strongest overall acceleration of any aircraft in the game, meaning that it can reach its top speed very quickly. However, like all other MiG-21s, the MiG-21bis cannot turn well and tends to bleed speed at an alarming rate during turns. Extended dogfights should therefore be avoided, as the MiG-21bis will often end up on the losing side.
The MiG-21 has a strong set of control surfaces including an all-moving tail, which keeps the aircraft responsive up to high speeds (>1300 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.

Usage in battles
This plane is fairly manoeuvrable at high speeds and since it accelerates very fast and climbs extremely well, it works well as an interceptor (you take off, reach around 1000 km/h, burstclimb at a 20-25 degree angle up to 6,000-7,000 metres and fire on anything you see in front of you) but this method has some risks.
First you're very prone to the Matra R530E and the infamous AIM-7 SARHMs (Semi Active Radar Homing Missiles) that can easily shoot you down since your plane becomes a brick at higher altitudes.
And sometimes, even if you achieve your interception objective, some enemies will fly in a different path, so they'll easily sneak up behind you and take you down if you're high or slow enough.
The 2nd way to play this plane is to fly at lower altitudes (below 2,000 m) and engage any target you may see, the risk here is that you're vulnerable to high-flying enemies that, again, can easily sneak up on you and take you down, so pay attention.
The 3rd way and probably the safest playstyle (recommended to stock players) is to "flank", or slightly sideclimb up to 4-5 km, wait until the majority of the enemy team is spotted and then come back to the battelfield and engage targets. It is safe because most (if not all) of your enemies, which are Phantoms and Mirages, will most likely play aggressively by climbing directly towards your team, so the only enemies you may encounter in your flank path are other stock players, AFK players, or, with a measure of unluckiness, cunning players that are aware of you. So pay attention when flanking and try to take the least frequented flight path (or the flyzone that is the farthest from the main battlefield or warzone).
Enemies you should pay attention to:
- Phantoms, particularly F-4E and EJ models: these should be your priority targets, F-4Es and F-4EJs are very well known for being extremely versatile and dangerous (even sometimes referred to as the best top tier jets in the game). These planes accelerate very well, can wield the dangerous AIM-9J AAMs that are able to pull 20 Gs of overload and very often can hit targets up to 3 km of range, have access to a very good amount of flares and have very responsive controls. However, a lot of Phantom pilots are very overconfident into their planes and will very often jump into a dogfight with you, as a MiG-21 which is a very bad idea for them. Everybody knows the motto "a slow jet is a dead jet" which is true but the MiG-21 has an ace up its sleeve against Phantoms: better low speed manoeuvrability and high speed manoeuvrability that can sometimes match the Phantom's turn rate! So if a Phantom attempts to dogfight you, go for it, they'll most likely lose, but only do so if your team is nearby or if there aren't any enemies nearby or you may end up getting taken out unexpectedly.
- The Mirage IIIC and the 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 RB24Js 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 you and then do oblique turns since they both bleed a ton of speed when turning and have a lower acceleration than you do. And if they try to fire a missile at you? Don't worry, pop flares, turn off afterburner, and pull hard.
Pros and cons
Pros:
- Impressive climb rate of 225 m/s, making this plane the 2nd best top tier climber behind the F-104S and above the Phantom FGR.2 and FG.1
- Increased flight performance compared to earlier MiG-21s
- Very capable both against aerial and ground targets
- Has access to flares that are fired downwards, which means that missiles will be dodged easier
- Stunning acceleration
- Very good energy retention
- Can wield 6 R-60s
- 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
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 manouverable R-60 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.
