South Korea’s LIG Nex1 is flexing its multi-domain missile muscle at a defense expo in Thailand — showcasing firepower that spans over land, air, and sea.
Leading the lineup is the Haegung surface-to-air missile, designed to shield warships from guided munitions and aircraft.
Equipped with radar and infrared seekers, it can strike targets 20 kilometers (12.4 miles) away at Mach 2 (2,470 kilometers/1,534 miles per hour).
Also sharing the spotlight is the Haeseong anti-ship missile, a subsonic sea-skimmer built to slip under radar and strike from up to 150 kilometers (93 miles). LIG Nex1 previously claimed that Haeseong achieved a “100 percent accuracy rate” in live-fire tests.
Below the surface, the Cheong Sangeo lightweight torpedo delivers rapid-strike capability against submarines. Deployable from ships or helicopters, it operates in shallow waters at up to 45 knots (83 kilometers/52 miles per hour).
An upgraded variant, tuned to counter decoys and boost underwater performance, is set to be unveiled by 2029.
Improving Army, Air Force Arsenal
For the army and air force, LIG Nex1 is developing the Cheongung III medium-range surface-to-air missile system.
It is equipped with a multi-function radar and mobile launchers that enable it to counter both ballistic and aerodynamic targets with improved flexibility and precision.
Rounding out the lineup is the Hyungung third-generation anti-tank munition, offering day-and-night capability through visual and thermal imaging systems.
Armed with tandem-charge warheads, the Hyungung serves as LIG Nex1’s answer to advancing enemy armor and evolving battlefield requirements.
LIG Nex1’s full missile suite is on display at Defense and Security 2025 in Bangkok, running from November 10 to 13.
