Assuming the PL-17, PL-20, and PL-21 are the same as shown in this model Su-35. There's got to be at least two ramjet missiles. One built off the PL-12 and a more ground up model.That would make 4 different medium/long range missiles. Sounds a bit too many. Pl15, the sino meteor, the big missile we saw on j16 and the alleged slightly smaller than pl15 missile tailored for j20.
@SinoSoldier We're also assuming the J-16 and whatnot haven't already been armed with these missiles for some time. What's not broadcasted isn't exactly what's not there. Maybe they've managed to integrate it/them with Su-35 only recently? Who knows. Could just be an error from Huitong.
