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.

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 Stronger than 38% of missiles
- Range
Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.
- 180 km Stronger than 46% of missiles
Firepower
Armament, payload and guidance.
- Warhead
Warhead mass. Heavier generally means larger effect radius, at the cost of range.
- 250 kg Stronger than 58% of missiles
- 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 Stronger than 36% of missiles
- Units built
Total production run. Higher means proven manufacturing, mature logistics and spares availability.
- 33 Stronger than 29% of missiles
- Operator countries
Number of countries operating the system. More operators means broader support ecosystem.
- 3 Stronger than 39% of missiles
