The source is unreliable, it says that the length of HQ-9 is more than 9 metres, Chinese official source say it's 6.51 metres. And it also claims that HQ-19 is designed to counter the Aurora bomber.
I'm sure that such projects exist, but we don't know exactly what their requirements are. In fact, a while ago Kanwa said that China approached Belarus for help with HQ-17,18,19. But the thing is, nobody knows HQ-18 and HQ-19 are. And these sources are just wild rumours.
this article,(文/刘尔琦 作者为中国航天科工集团第二研究院党委书记)The author is the party secretary of 2nd institute, China Aerospace Science and Industry Research Group, Published in "Observation magazine" (瞭望),the last picture show Tor M1, should be domestic, but it dosn't mention HQ-17 or HQ-18.
there are speculation about China devolop HQ-18,19 in chinese internet.my last post from some one's source, just for reference, he also say HQ-19 is only a project,he provide a russia SAM for reference,I post these to see people's oppinion.
the first picture was SA-6 "gainful" not Sa-17.[qimg]http://bbs.bovii.com/attachments/month_0806/20080621_f702a2a0b766200933d8zeT29tZQXGdG.jpg[/qimg]
just for reference.
That's what I said, only I used the Russian designation 2K12 Kub ( Cube ), not the NATO code name SA-6.the first picture was SA-6 "gainful" not Sa-17.
there is talk that Sa-15 will replace HQ-7 ,but during the military parade,old HQ-7 take part in the parade indicate that HQ-7 will continue to serve well into 2010.
