South Korea LIG Nex1
SSM-700K Haeseong
South Korea's indigenous ship-launched anti-ship cruise missile, designed as a domestic alternative to the US-made Harpoon and fielded across the Republic of Korea Navy's destroyer and frigate classes. It uses GPS-aided inertial navigation for mid-course flight and active radar homing in the terminal phase, powered by a Hanwha Techwin turbojet.
In service since 2006 · 3 operator countries

💲 ≈ $1,750,000, South Korea's Defense Acquisition Program Administration has not published an official per-unit price, so this figure should be read as an industry estimate rather than a confirmed government number. It is broadly consistent with comparable Western subsonic anti-ship missiles, such as the Harpoon Block II at roughly USD 1.4 to 3 million depending on contract year and the Naval Strike Missile at roughly USD 2 million.

Full specifications
Performance
Speed, range, altitude and engagement capability.
| Max speed (Mach) Maximum speed as a multiple of the speed of sound. Mach 2+ is typical for air-superiority fighters. | 0.95 Mach |
|---|---|
| Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence. | 180 km |
Firepower
Armament, payload and guidance.
| Warhead Warhead mass. Heavier generally means larger effect radius, at the cost of range. | 250 kg |
|---|---|
| Guidance How the weapon finds its target: inertial, GPS/GLONASS, active/semi-active radar, infrared, laser, TV, wire. | GPS-aided inertial navigation (mid-course), active radar homing (terminal) |
Physical
Dimensions, weight and crew.
| Length Overall length including gun/probe where applicable. | 5.46 m |
|---|
Propulsion
Engine, power and fuel.
| Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet… | Turbojet (Hanwha Techwin SS-760K / SSE-750K) |
|---|
Program
Cost, production scale and operators.
| Unit cost Approximate flyaway/unit cost where public. Defense pricing varies hugely by contract, offsets and configuration. Lower is cheaper. | $1,750,000 |
|---|---|
| Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability. | 33 |
| Operator countries Number of countries operating the system. More operators means broader support ecosystem. | 3 |
