The Hong Qi-7 (HQ-7) is a reverse-engineered copy of the French Crotale missile defense system, one of the most successful air defense systems ever developed. Crotale derivatives comprise three hundred systems deployed in fifteen nations.[i]The HQ-7 is designed for rapid deployment in multiple theatres.[ii]The PLA estimates its single-shot kill probability as 80 percent.[iii]The primary differences between the HQ-7B and earlier HQ-7 systems are upgrades to the acquisition radar and the P4R vehicle:[iv]The original HQ-7’s j-band acquisition radar can detect up to 30 targets and track 12 of them at a range of 17 km.[v]By contrast, the HQ-7B features s-band active electronically scanned array (AESA) radar, which can detect up to 48 targets and track 24 of them at a range of 20 km.[vi]A normal battery includes one vehicle with acquisition radar and three TELAR vehicles, which are equipped with four missiles each.[vii]The Naval variant FM-90 (N) is proposed for export and can be mounted on frigates and destroyers. Each launcher has an eight-missile carrying capacity that can be used t intercept sea-skimming anti-ship missiles.[viii]

Strategic Implications

The design philosophy for the French Crotale—off of which the HQ-7 is based—is to fill the role of a short-range, low-altitude, concealed interceptor with a fast reaction time. The development of hypersonic Soviet aircraft with short radar display times spurred French development of the Crotale, which has a reaction time of less than ten seconds and a reload time of two minutes.[ix]Though the original HQ-7 system is outdated, today Beijing uses the HQ-7B as a short-range level of point defense against low-flying aircraft and tactical ballistic missiles, primarily for coastal and border defense of industrial and military assets. Moreover, HQ-7Bs exported to Iran and Pakistan could prove problematic for older generations of U.S. aircraft or short-ranged artillery in the event of a conflict.
