The Type 054A carries HQ-16 medium-range air defence missiles and various anti submarine rockets in a VLS system. The HQ-16 provides area air defence from all engagement angles up to a range of 50 km, a considerable improvement over the HQ-7 carried on the Type 054 which have inferior range and limited engagement angles. Contrary to HQ-9 VLS on Type 052C destroyer which adopts a cold launch method, HQ-16 appears to adopt a hot launch method instead, with the same design principle of US Mk 41 VLS: a shared common exhaust system is sited between the two rows of rectangular launching tubes.The VLS system is also capable of firing anti-submarine missiles.[4]
