Before it got nerfed HEAVILY in the flight model department, the JA37s used to have a better flight model than the Mig-23s. However, as always when something overperforms according to Gaijin, some “SeKrIt DoCuMeNtS” have been found to nerf the flight model.
You are now struggeling to dogfight F4Es. You bleed speed like a 21 and accelerate like an F5.
Combine that with the tracerless gun because the audacity of having a tracer round included (yes they exist, sweden didn’t just use them because unlike ingame, the radar gunsight doesn’t have an epileptic seizure) is to much of a historical inaccuracy. Because Gaijion would never ahistoriacally buff or nerf vehicles or weapons. Like the Stinger. Or the Abrams. Or the Leopard 2A4, A5, IRIS-T, SPIKE, Brimstones etc. ad absurdum.
A tracer is too much though, because then you could acually learn to shoot the gun.
The missile loadout is also mid at best. At 12.0 you find the F4S which get access to up six Aim-7Fs, you get a maximum of two 7-E2s. Which are good in a headon up to four km. If they actually track the target and don’t try to maim a teammate 40° offbore.
Your heatseekers are four (six if you ditch the 7E2s) Aim-9Ls, which are certainly decent for the BR, especially on a fighter, but just .3 above you sits the F16A, which gets access to six 9L and has a WAY better flight model.
At 11.7, .3 BRs below you, sits the Mig 23 ML family. All shit on you in top speed, turn performance and radar missiles. R23s are arguably better than the 7E2 already, the 24s blow them out of the water.
While the GSH is a water pistol, it actually gets a tracer. Wohoo, you can learn to lead you gun and don’t just have to guesstimate where your rounds go.
9Ls are better than R60s. That is one advantage you have over the Mig 23.
The other one is you get 360 countermeasures. So you can turn on periodic flares to prolong the iinevitable.
Coming back to the topic, a lot of planes like the JA37 are just forgotten. They had a glory period and then fell off. With the main grinding method being premiums now, these planes do not see enough play to be affected by Gaijns balancing “algorithm”. They don’t seem to see enough play, and those that play them are usually not the average joe, which result in higher-than-average stats.
