Well, S-300 / S-400 has ranges in excess of 250km, giving the missile site a lot of room to work with for trajectory shaping. I guess this would explain some of the recent research into constrained terminal trajectory guidance algorithms.If the trajectory is shaped to come down from the vertical direction (which is available when the missile is not flying out to maximum range) then the engagement gives the missile:Maximum energy for end-game maneuversMaximum target cross-section, allowing the smaller missile radar to detect the target at a reasonable rangeMinimum target electronic warfare, especially if target EW is through the radar.Also, reasonable range may be as low as a few kilometers, depending upon the accuracy of the low frequency radar.
