Haeseong III Development
The South Korean Defense Ministry officially unveiled the Haeseong III on February 14, 2013, two days after North Korea conducted its third nuclear test.1 The third variant in the Haeseong missile series, it was developed to equip South Korean submarines with greater precision strike capability. The Haeseong III can reportedly be employed as both a land-attack and antiship weapon.2 The missile was developed by the state-run Agency for Defense Development (ADD) and defense firm LIG Nex1.
Specifications
Reports indicate that the Haeseong III has a range of 1,500 km, and is highly accurate with a circular error probability (CEP) of 1-3 m.3 It uses a turbojet engine, allowing for supersonic speeds up to 830 m/s. 4 The missile is launched from the submarine’s torpedo tube, thus allowing it to equip submarines that do not have the more advanced vertical launch systems. The waterproof capsule that encases the missile travels to the surface, and opens for a ‘cold launch’ ejection.5 A cold-launch system uses compressed gas to propel the missile out of the launcher before its own engines ignite.
Service History
The Haeseong III entered operational service in 2013. It currently equips South Korea’s 1,800-ton Son Won II-class (KSS-2 or Type 214) submarines, and is scheduled to equip ROK’s developing 3,000-ton KSS-3 submarines.6
