Description

In 1963, after rejecting a deal of MiG-19s in search for a new frontline fighter, Finland became the first country outside the Warsaw Pact to purchase the MiG-21, starting with MiG-21F-13s and building their long and prosperous relationship in purchasing Soviet aircraft. Their long service of the Fishbed would culminate in 1977, when Finland acquired 26 examples of the MiG-21bis airframe, specifically the Fishbed-N variant with the Polyot-OI guidance system instead of the Lazur system. These aircraft would remain in Finnish service until 1998, when they were replaced by the F/A-18C Hornet after the end of the Cold War.

The ▄MiG-21bis (NATO Code: Fishbed-N) was introduced in Update "Fire and Ice". This aircraft is completely identical to the MiG-21bis found in the Soviet tech tree, and as such, plays exactly the same. The only differences are cosmetic, such as the camouflage and the names used on its missiles (i.e it has the export R-60MK instead of the R-60M, which is the exact same missile with a different name). The same tips and cautions should be exercised when flying this aircraft; chief of which being the incredible AoA/instantaneous turn and engine acceleration power to utilize, while being cautious of the weak energy retention and subpar missiles compared to many of your adversaries at this battle rating.

The MiG-21bis 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 1,365 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 MiG-21bis 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 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-21bis 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 1,365 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

The MiG-21bis 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.

First, the MiG-21bis is prone being hit by a SARH (Semi-Active Radar-Homing) missile such as the AIM-7F or R-24R that can easily shoot the MiG-21bis down since the plane becomes a brick at higher altitudes. And sometimes, even if the MiG-21bis succeeds in its interception objective, some enemies will fly in a different path, so they'll easily sneak up behind the MiG-21bis and take it down with missiles if it is high and slow enough.

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 MiG-21bis is left vulnerable to high-flying enemies that, again, can easily sneak up and take the MiG-21bis down, so pay attention to the surroundings and avoid getting an IR missile shot up into the engine.

The third, and probably safest, way to play the MiG-21bis 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 MiG-21bis does not appear on their radar (additionally, turn off the MiG-21bis' 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 MiG-21bis 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 MiG-21bis pilot can begin engaging in their favour 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.

A more risky but rewarding playstyle is to use 2 x R-13M-1 and 4 x R-60MK, or 4 x R-13M-1, and take advantage of MiG-21's 225 m/s climb rate, which in theory, is superior to even the Phantom 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 3 km 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.

Enemies worth noting:

• F-4 Phantoms, particularly those with PD radars: these should be the MiG-21bis' priority targets, F-4s are well-known for being extremely versatile and dangerous. These planes accelerate quickly and wield dangerous AIM-7 SARH missiles that can shut down the MiG-21's climbing efforts. While the F-4E variant can be relatively easily countered with chaff to interfere the radar, the ones with PD radars like the F-4J and F-4S can easily track and destroy the MiG-21, requiring notching to break off the radar lock. These planes also have a large number of countermeasures, so the MiG-21's effort to attack them with IR missiles can be easily thwarted. At closer ranges, the fight is more even, as the F-4's Sidewinder missiles can be diverted with countermeasures (though beware if it is a F-4 equipped with the all-aspect AIM-9L Sidewinder missile) However, the dogfight can still be tough if the F-4 has the right pilot playing to its strengths, so be wary and don't assume the MiG-21 has control of the dogfight until the MiG-21's nose is pointed right at the target's six o' clock.

Pros and cons

Pros:

• Impressive climb rate of 225 m/s
• 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 R-60MKs
• 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
• 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

By the late 1960s, 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-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.
