Russian anti-ballistic capability? Are you talking about S-500? The old Soviet stuff's not useful or usable these days. But if we're talking vaporware, China's got HQ-2X that's supposed to be the equivalent of S-500 BMD capability. And that's just one line of SAMs which may have been in service for a while already. Let's not forget Chinese ASAT demonstration proved the ability is more than concrete. There is simply no point in BMD against the big three nuclear powers. I'd say China's ability to achieve higher LEO, fast pace, kinetic kill back in 2007 demonstrates far superior BMD ability than Russia. HQ-16 having 70km equivalent range compared to previous Buk's 50km goes towards showing having better fuel and rocket technology.
R-37? That's basically an unproven Phoenix missile that's designed to maybe engage large unmaneuverable targets at best. Let's not forget that Russian air doctrine still places emphasis on WVR simply because they've never had any real success with BVR unlike the USAF. If these long range R-77s and R-37s actually worked, China (and anyone who could) would have purchased thousands. Even back in the 90s China began to desperately develop its own replacements for R-77s so J-11B can use Chinese ordinance. The only Russian A2A missile that was proven successful is the Archer. It's not hard to make long range missiles. The hard parts lie in their seekers, ECCM, guidance, and energy management.
As for PL-15 it is nothing like Meteor. Maybe equivalent to 120D but it has dual pulse motors for better energy management. Meteor has better range, better energy, and ramjet powered. PLAAF's analogue of the Meteor is PL-21 if I recall. It's not the thin long range missile seen on J-16 years ago but with ramjet intakes.
The S-300V4 and S-400 already have limited anti-ballistic capabilities, which are better than everything the chineses field to this day, since they actually operate no mobile anti-ballistic assets. S-500 is the paradigm of the serie; It actually exists, compared to the HQ-2X. I notice that you don't even know its designation but still extrapolate on its capabilities; Quite proffesionnal
"It's not hard to make long range missiles" yeah right, that's why they chineses still have not fielded anything comparable to the R-37 or R-33E.
Have you been living under a rock?
The DN-3 is in excess of anything America or Russia have achieved in ABM, being able to hit missiles in orbit before they separate.
Yes, but while living under a rock, I have been able to understand how ABM defence works, compared to you it seems...
In fact what you describe as the capability "to hit missiles in orbit before they separate" is literrally the principle of EVERY SINGLE Heavy ABM defence. It's called mid-course interception, and it's not a particularity of the chinese asset: guest what "GMD", the US equivalent, means ?
Ground-Base Midcourse Defense.
Nothing particular for the PL-15: "large range combined with large no escape zone for any target" is something you can see in basically every other comparable missiles.
