Evading air-to-air missiles isnt like the movies.
Its a lot harder than you think it is, with only one current tactic currently working against modern missiles, which actually involves flying directly at the missile like a massive game of chicken. The new generation of air-to-air missiles coming out, like the ones with new AESA radar, are very likely to be all but impossible to survive.
No, there´s more tactics that works against modern missiles, flying towards it and then maneuvering is just one of the more effective, if your timing is good enough, you can force most missiles to miss every time. And it should also be mentioned that modern ECM has GREATLY improved in the last 20 years.
AESA isn´t an automatic "i win" button, it improves data generated which in turn allows the programming to function more effectively etc etc, but that does not equate autohit.
In fact, last i read about it, it seems more likely that recent upgrades are considered an almost requirement to not come near invalidating missiles due to defensive improvements, tactics and ECM mostly, but viable decoys are also almost certainly coming in the next decade.
There is good reason why the Russians already have made it a standard tactics to never fire less than 2 missiles against an air target, with different seekers, because it´s become too easy to avoid just one. Other nations are mostly either following or debating following this change of tactics. USA is actually the only major military i have not yet heard anything from about doing the same, although i expect that is because of the influence of the military industry generally promising things they can´t deliver, but being loud enough about it for any dissent to be overruled by sheer noise.
For comparison, the currently most used US AMRAAM model is expected to have 20-25% hit probability against a currently modernised Su-27 derivative, 20 years ago, that number was over 50%(and over 60% vs export versions). Latest model AMRAAM is "better", but noone really knows if its 1% better or 10%, nor are they replacing the older ones until they´ve been used up anyway so barely any production.
When Meteor was designed, it was meant to be a 1 shot 1 kill missile, yet despite being probably the most effective missile currently in existance, its hit probability against a modern non-stealth fighter is likely not above 60%. Similar with IRIS-T and the never built upgraded Sidewinder.
The primary issue with radarguided missiles is also very very simple, when the missile is close to its target, it is far from the launching fighter which means if the target has strong ECM, it can easily(relatively) overpower guiding data. And its even worse if the missile is an Active Radar homer, because then it is even more disadvantaged in pure size and power, as with a Semiactive Radar homer, the launching plane´s "lock" can at least usually project enough pulse energy to not just simply loose that "lock".
