Message: <blockquote data-quote="totoro" data-source="post: 221797" data-attributes="member: 6313">Does anyone have access to some credible literature or official sources offering information on missile families that are part of s300 SAM?I would like to answer the following question:What were the principal reasons 5v55R missiles is labeled with 25ish km more range over 5v55k, and in turn why is 5v55rm labeled with 15ish km over 5v55r?Likewise, why is 48n6 labeled with 150 km range, 48n6d with 200 km and 48n6dm with 250 km?I understand the ranges that are out there are subject to various interpretations and context.But is there info to confirm rocket motor section of 5v55 variants is the same in all its iterations? Then the 48n6 missile came with new rocket motor (among other things) and all the following variants again have the same motor?If the above assumption is true, it would suggest all the range increases were result ofA) different trajectories used (due to different guidance methods and/or simply wider seeker area in the missile)B) targeting radar improvements, enabling better tracking of both targets and own missiles at longer ranges. (but if this is the reason, it wouldn't really need a different missile variant, would it? though again, more jamming resistant seeker might alone be enough for a new missile designation)C) marketing/doctrinal decisions and changes, depicting stated ranges as max ranges versus targets of various speeds and flight profiles. (as shooting at mach 1.6 fighter and mach 0.9 b707 would certainly be different)Or is it also likely that family subvariants had enlarged motor sections, due to newer and smaller electronics, or they received different and more potent rocket fuel?</blockquote>
