Hyunmoo-3
The Hyunmoo-3 is a cruise missile fielded by the South Korean military designed by Agency for Defense Development (ADD). The name Hyunmoo () comes from a mythical beast described as the "Guardian of the Northern Sky", perhaps hinting North Korea. Design and development
As a signatory of the multilateral Missile Technology Control Regime, South Korea agrees to refrain from importing a non-indigenous ballistic missile with a warhead larger than 500 kg, or a range of more than 300 km. In addition, a bilateral agreement between the ROK and US limits indigenous South Korean produced missiles to no more than  in range, and warheads no larger than . (In September 2017, the presidents of the ROK and the US agreed "in principle" to lift these bilateral limits, increasing the possibility of a longer-range, more powerful Hyunmoo-4 in the future.) Therefore, a heavy emphasis was put on developing long-range cruise missiles by the South Korean government. With the introduction of Hyunmoo-3, the Republic of Korea Army created the Missile Command in order to efficiently manage these missiles. Despite the name, the Hyunmoo-3 bears no resemblance to the previous Hyunmoo SSM, which were improved versions of Nike Hercules surface-to-air missiles that were converted into short-range high-speed surface-to-surface ballistic missiles in response to North Korea's Scud-B and Nodong-1 missile threats. Instead, the new missile's designs are strikingly similar to the United States Tomahawk cruise missile. It is powered by a turbofan engine, and has a maximum payload of  of conventional explosive. The guidance systems consist of inertial guidance system and global positioning system. Variants

Hyunmoo-3A, which was nicknamed "Eagle-1" (독수리-1) during the testing, has a range of 500 km, while Hyunmoo-3B, nicknamed "Eagle-2" (독수리-2) Cheonryong (천룡 순항 미사일), has a range of . Hyunmoo-3C, or "Eagle-3" (독수리-3), will be capable of striking its target up to  away. This is a significant improvement from Hyunmoo I which had a range of  and Hyunmoo-2A, which only has a range of , both of which were ballistic and not cruise missiles. s and KSS-III-class submarines will be equipped with these Chonryong submarine-launched cruise missiles inside their K-VLS cells. A Hyunmoo-3B air-launched cruise missile with over  range exists and it is called Boramae. A submarine-launched cruise missile called the Haeseong III is designed to be launched underwater from submarines. It is actually the designation for the Hyunmoo-3 cruise missile when launched from a submarine and is unrelated to the SSM-700K Haeseong missile design. Operators
