The LY-80E’s maximum/minimum interception altitude is 18km/15 metres, while its maximum interception range for combat aircraft is 40km, and between 3.5km and 12km for cruise missiles flying at an altitude of 50 metres at a speed of 300 metres/second. Single-shot kill probability is a claimed figure of 85 per cent against combat aircraft, and 60% against cruise missiles.The MR-SAM rounds are cannisterised, and are cold-launched in vertical mode. The missile guidance system is of the composite type, comprising initial independent inertial guidance plus intermittent illumination, and semi-active homing terminal guidance. A single LY-80E MFV can engage four targets simultaneously, and the entire system has a reaction time of 12 seconds. The MR-SAM round’s weight minus the launch tube is 615kg, while that with the launch tube is 1,300kg. Missile length is 5.010 metres, diameter is 0.340 metres, maximum missile overload is 25 G, and the cruising speed on a high and long trajectory is more than 750 metres/second.
A single GV controls two to four MFVs, with six rounds of MIT equipping each MFV. The SV comes equipped with a solid-state S-band 3-D passive phased-array radar mounted atop a raisable mast. Once the target is detected, the SV performs automatic IFF, threat judgment, flight path processing and provide target engagement information for the tracking-and-guidance radar. The S-band radar has a slant range of 140km and can detect targets flying at an altitude of 20km. Up to 144 targets can be monitored, and of these, 48 can be tracked. The GV performs target acquisition and tracking, and identification of target-types. It also controls the missile-launching and illuminates the target after the missile is fired. The L-band passive phased-array radar atop the GV has a range of 85km, can detect up to six targets and track four of them, and provide fire-control/guidance for up to eight MR-SAM rounds. The L-band tracking radar adopts a two dimensional phase-scanning system that consists of sub-systems such as an antenna, feed line, beam controller, transmitter, receiver, frequency source, signal processing, software and data processors, servo unit, anti-jamming sub-system, antenna base, cooling unit and simulator. It searches and tracks the targets, measures the 3-D coordinate data and sends it to the fire-control unit, which in turn receives target indication information and combat orders from the CV, and organises the fire-channels for engaging the targets. Besides, it also reports the operational and equipment statuses of the MFV.

In Addition to the above, CETC, CPMIEC and NORINCO have since 2002 developed several types of customised, country-specific air-defence systems ranging from LR-SAMs to VSHORADS (see below) solely for export in Africa, Central/South America, the Middle East and Southeast Asia.
