C - 602 The C - 602 , also known as YJ - 62 , is a Chinese subsonic anti - ship missile that can also be used as a land attack cruise missile . C - 602 made its public debut in China at the end of 2006 during the 6th Zhuhai Airshow , though the name begun first appear in 2005 . The development program itself appears to date back as far back as 1989 , under the designation " XY - 41 " . In various US sources of the 1990s and early 2000s the missile was also referred to as " The Land Attack Silkworm " . The missile is reportedly deployed onboard the Type 052C destroyer . The subsonic missile has a designation of YJ - 62 , with YJ short for Ying Ji ( Yingji , 鹰击 ) , meaning Eagle Strike . In addition to anti - shipping capability , the missile is also capable of land attack . The missile has a maximum range in excess of , though the exact number is uncertain , but for the export version , the maximum range is reduced to to meet the international arms trade regulation which limits the maximum range below . The maximum speed of the missile is greater than Mach 0 . 9 but this speed is greatly reduced over the rugged terrain when used for land - attack missions . The missile can be launched in Sea State 6 environment . The cruising altitude over the ground can be as low as while the cruising altitude over the sea can be as low as . During the terminal attack phase against ships , the altitude is further decreased to above sea level . The missile is propelled by a turbojet engine with a solid fuel rocket booster weighing around . The missile is equipped with a “ mono - pulse frequency agile ( active ) radar seeker ” with a maximum detection range in excess of and a maximum lock - on range of . The sector of the scan of the seeker is ± 40 degrees . For the midcourse flight , inertial guidance is used with the help of strap - down inertial measurement unit ( IMU ) and GPS for the export version , while domestic version also incorporated GLONASS and domestic navigational systems . A variety of warhead could be adopted , and the fuse for the anti - ship version is “ delayed electro - mechanical contact fuse ” . The mid - body wings which deploy following launch . The engine inlet is mounted slightly forward of the cruciform tail fins . The missile has incorporated the capability similar to the Boeing Harpoon , so that it could abandon the original target and switch to more threatening ones should such threat arise , but it is not clear whether this capability in built - in like the Boeing Harpoon or achieved via data link , or a combination of both . A new version of the missile with turbofan engine has already being completed and the submarine and air - launched version ( tested on a version of Xian H - 6 ) are also reported to be under development . However , such reports have yet to be confirmed because many domestic Chinese sources have disputed the missile in the photo by claiming it might have been a cruise missile instead . The missile was authorized for export by the Chinese government in 2005 . Specification : CM - 602G . At the 9th Zhuhai Airshow held in November 2012 , a new member of C - 602 series designated as CM - 602G made its public debut . CM - 602G is a dedicated land attack cruise missile with range of 290 km to comply with the export restriction imposed by Missile Technology Control Regime , and armed with a 480 kg warhead . One of the major improvement of CM - 602G over earlier models of the series is that a data link is added so that the operator can change to target after the launch , though the fire - and - forget option is still available . CM - 602G can also be programmed to have a pops up mode to flyover ground obstacles up to 800 meters and thus shorting the reaction time for enemy to defend the intended target . CM - 602G is designed to attack land targets within 25 km of the shoreline .
