The KP-SAM Shin-Gung or Shin-Kung (Korean: hangul: 신궁, hanja: 新弓) is a South Korean shoulder-launched surface-to-air missile manufactured by LIG Nex1. It is marketed internationally as the Chiron.
The Shin-Gung was created to protect ROK troops in the forward area, which started in 1995 under the direction of LIG Nex1 Co., Ltd. In late 2003, the delivery of the Igla SAMs from Russia in payment for Russian debts to Korea appear to have solved the problem momentarily. The KP-SAM began production in 2004 with extended trials in early 2005. In late 2005, the KP-SAM Shingung entered service with the South Korean Army, after being in development for nearly 8 years. The South Korean Army has ordered some 2000 units to be delivered in the near future.
While the missile system externally resembles a French Mistral system, the entire missile system including the seeker, control section, warhead and motor were developed and manufactured in South Korea. The missile features integrated IFF systems, night and adverse weather capabilities, a two-colour (IR/UV) infrared seeker to aid in negating infrared countermeasures (IRCM) and a proximity-fuse warhead. During development tests the missile scored a 90% hit ratio.
According to Agency for Defense Development officials, the missile is superior to the American FIM-92 Stinger or the French Mistral in hit probability, price and portability. It had been involved in a missile test where the Shingung's missile made impact on a low-flying target as high as 3.5 kilometers with a speed of 697.5 m/s (more than Mach 2.36) and a distance range of 7 km.
