What about the SPS 141-100? I remember seeing a screenshot of it before the 3rd gen migs were released.
LOL
Nope. Somebody might have mentioned SPS-141, but that's like everything.
1) It would require new slot for plane as we've already reached maximum compilable lenght of weapon code for IL-2.
2) It would require actually working radar, what we have now is just some indication inside cockpit. We would need "outer-world" expression, working Radar warning receiver (that uses that outer-world expression) and then we can think about possible countermeassures and actuall ways of how to implement them. That would require it's own physical model - the jammer has some energy (and function), radar has it's energy, you need to get return energy of radar that is big enough to be recognised over the jamming - and then, with different wavelenght the energy degrades with distance differently, different targets have different RCS (basically reflective plane) that return different ammount of energy,...
Plus - SPS-141 was said to be able to knock out really wast part of what AADefense is watching - the theory was that the jamming plane (disadvantaged by heavy jammer) will fly together with combat equipped planes that will strike the bandits + defend jammer.
As a bonus, if you've kept reading this far, I will tell you that Bis was not the only plane capable of carrying it - it could also be fitted on M/MF! But, that required modiffying the centerline hardpoint and cockpit a bit - by adding jammers cabelage and "small" pannel for actually operating the SPS. Minimally the later had to be done for serial Bis.
