Michael Elleman, вЂњNorth KoreaвЂ™s Hwasong-14 ICBM: New Data Indicates Shorter Range Than Many Thought,вЂќ 38 North, November 29, 2018.

As a weapon, the Hwasong-14 would represent a niche capability straddling the Hwasong-12 and Hwasong-15 its absence could that Pyongyang does not aim to procure it in larger quantities. In a parade commemorating the WorkersвЂ™ Party of KoreaвЂ™s 75th anniversary on October 10, 2020, North Korea displayed the Hwasong-12, Hwasong-15, and a large unnamed ICBM-with the Hwasong-14 conspicuously absent from the proceedings.

It is currently uncertain whether the Hwasong-14 has entered serial production. In addition, the latter Hwasong-14 featured yaw maneuvering motors previously absent on the first Hwasong-14вЂ™s second stage. On July 28, the missileвЂ™s first stage fired for 151 (+6) seconds and its second stage for 224 (-9) seconds. In the July 4 test, the Hwasong-14вЂ™s first stage fired for 145 seconds and its second stage fired for 233 seconds. Reports suggested that North Korea achieved these increases through changes to the missileвЂ™s structure and throttle control systems. The Hwasong-14вЂ™s performance in its second, July 28 test well exceeded of its first, traveling for 47 minutes to a range of 1,000 km and reaching an altitude of 3,700 km.

government first estimated the Hwasong-14вЂ™s range to be 7,000 вЂ“ 9,500 km. 8 Based on this performance, analysts initially estimated that the Hwasong-14 could reach up to 8,000 kilometers if fired in an easterly direction. In its first test, the missile flew on a lofted trajectory to a range of around 930 km and an altitude of 2,803 kilometers. With a range of over 10,000 km, the Hwasong-14 is the first North Korean missile able to reach mainland North America. In a subsequent statement, North Korean state media claimed that the missile could вЂњstrike anywhere on earth.вЂќ 7 DateДЇlight time: 39 min distance traveled: 930 km apogee: 2,803 km.ДЇlight time: 47 min distance traveled: 1,000 km apogee: 3,700 km. The missile launched from Panghyon in the countryвЂ™s northwestern region and traveled for 39 minutes before landing in the Sea of Japan. North Korea successfully flight tested the Hwasong-14 for the first time on July 4, 2017. Earlier mockups of the Hwasong-13 (KN-08/14) did not feature these elements. 5 These small solid-propellant rockets, visible on the interstage, are used to decelerate a missile stage during separation to ensure the multiple stages do not collide, an critical element for a reliable multistage missile. 4 The Hwasong-14 also employs eight retrograde rockets to aid in separating the first and second stages. While little imagery exists of the Hwasong-14вЂ™s second stage, analysts have highlighted design commonalities with the Taepodong-2 and Hwasong-13вЂ™s third-stage boosters.

North Korea conducted at least two suspected ground tests of the Hwasong-14вЂ™s вЂњKorean-style high-thrust motorвЂќ in March and June of 2017. The Hwasong-14вЂ™s first stage is powered by a large liquid-fueled engine and four vernier thrusters in a configuration similar to the Hwasong-12. With a 500 kg payload, the Hwasong-14 would be capable of striking targets in the Western United States. Analyst estimates place the missileвЂ™s range at 7,000 to 10,400 km depending on the missileвЂ™s payload. The Hwasong-14 is a direct evolution of the single-stage Hwasong-12 intermediate-range ballistic missile (IRBM), which North Korea first tested in May 2017 to a range of around 4,500 kilometers.
