The Hwasong-12 (Korean: 화성 12, meaning Mars 12; KN-17 under the U.S. naming convention)[8] is a mobile intermediate-range ballistic missile developed by North Korea. The Hwasong-12 was first revealed to the international community in a military parade on 14 April 2017 celebrating the Day of the Sun which is the birthday anniversary of North Korea's founding President, Kim Il-sung.

Design[edit]

Estimated maximum operational range of the Hwasong-12 (KN-17) missile: 3700 km (inner circle), 6000 km (outer circle)

Based on photos of the launch on 14 May 2017, the Hwasong-12 appears to be a single stage design, using a single main engine along with four vernier engines. The arrangement appears similar to the "high-thrust" engine test conducted in March 2017.[9] Alternatively, it could be based on the engine used in the older Hwasong-10 with the addition of two more verniers.[5]

Initial estimates suggest the Hwasong-12 would have a maximum range of between 3,700 kilometres (2,300 mi)[5] and 6000 km (3728 mi.) (ICBM means a range of at least 5500 km).[6] In the April 2017 military parade the Hwasong-12 was displayed on the Hwasong-10 mobile launcher, and it may be intended to replace the similarly performing Hwasong-10 which has been shown unreliable during its test program.[10][11]
