And what if you can not track it.

 Target speed of almost 1000 m / s this is true, it is strange that in Operation Tallinn grab this goal is very difficult, I tried a lot of times, it was possible only very rarely.

 Strange if another shoot at moving away goal, then the maximum speed of 300 m / s, why do Volkhov then 420 m / s, Volkhov system older than Vega rocket and she also weaker.

 At the C-200 'Vega' Hypersonic missile, the idea should not be a problem, it just easily catch up with the target.
