I'd like to request a brief mention on the Sinodefense web site on the first export of KS-1A missile system:
And its capabilities:
"01/09/2001: In a report by Jane's Defense Weekly, China National Precision Machinery Import and Export Corporation (CNPMIEC) upgraded existing KS-1 surface-to-air (SAM) systems to KS-1A standards. The KS-1 is a low-to-high altitude SAM system developed to supplement the older HQ-2 SAM that entered service in 1967 and was based off the Russian SA-2 Guideline family. The new KS-1A system featured a trailer mounted phased array radar system, similar to the one used by the US Patriot SAM system. The new radar is claimed by CNPMIEC to enable the KS-1A to engage three targets simultaneously. The KS-1A missile's dual thrust solid propellant motor has been upgraded, increasing its maximum range and altitude to 50km and 88,560 feet. Speculation about the source of the technology upgrades centered on Israel and Russia, both of which have defense cooperation programs and arms sales with China.
