LeiShi-6 Precision Guided Glide Bomb
The LeiShi-6 (LS-6, LeiShi = “Thunder Stone”) precision guided glide bomb was first revealed in October 2006. The weapon comprises a conventional 500kg general purpose bomb and guidance and range-extension package developed by Luoyang Optoelectro Technology Development Centre (LOEC). The package is a GPS/INS-based guidance and targeting system, along with a pair of foldable wings, which, after bolting onto the bomb, transforms the weapon into a “stand-off” precision guided ammunition.
The weapon package allows conventional “dumb” bombs to be converted into smart weapons. The package provides both guidance and navigation to a target, in all-weather day/nigh conditions with great accuracy. The wings, which extend from a compact folded position upon deployment, give the bomb a great deal of manoeuvrability. Such a capability would allow the pilot to release the weapon from a standoff distance to protect both himself and the aircraft from surface-to-air weapon threats. When released from an altitude of 10,000m, the LS-6 could attack a point target 60km away at a speed of Mach 1 with an accuracy of better than 15m. When assisted by an auxiliary propulsion system, the weapon can reach a maximum range of 300km.
Chinese official says "about a dozen" launch tests of the LS-6 precision bomb kit have been carried out using a Shenyang J-8B as the test aircraft. The program began in 2003, with testing completed by 2006. A family of weapons is planned. It is not known whether the weapon has been equipped by the PLA. An obvious weakness of the weapon is its reliance on foreign satellite navigation systems such as the U.S. GPS and Russian GLONASS. However, China is expected to be able to deploy its own independent global satellite positioning and navigation system within the next ten years. Once fully deployed, the PLA would possess capabilities similar to the U.S. Joint Direct Attack Munitions (JDAM).
