CostI wonder what's the rational behind fielding HQ-6A, HQ-12A, and HQ-22 (it appears in limited numbers), which would complicate logistics as well as training, when their HQ-17A, HQ-16B and HQ-9B already provide comparable or greater air defence coverage, and with VLS being more flexible and faster responding at the same time?
What's the advantage of the HQ-22 over HQ-9B? Based on what I know, HQ-9B has a roughly 230km range, while HQ-22 has a range of 170km (or only 100) range at most. Is it because HQ-22 is cheaper and more capable of targeting low-flying cruise missiles?the production of the HQ-22
