The Hwasong-17 (Korean: 《화성포-17》형; Hanja: 火星砲 17型) is a new missile unveiled by North Korea on October 10, 2020, the 75th anniversary of the founding of the Workers' Party of Korea parade.[4] This missile is seen as a new iteration of the Hwasong-15 and is another step along the path of North Korea's intercontinental ballistic missile (ICBM) program.

At the Self-Defense-2021 defense development exhibition, the missile was shown labeled as the Hwasong-17.[5]

Description[]

The Hwasong-17 is assumed to be a two-stage, liquid fuelled road-mobile ICBM carried by a 22-wheeled vehicle. The missile itself is judged from images to be 26 m long with a diameter of 2.7 m. The exact capabilities of the missile are as yet unconfirmed, though speculation by experts has fueled questions as to whether it could reach cities within the United States and potentially evade U.S. missile defenses too.[6] It also might have the capability of carrying multiple re-entry vehicles (MRVs),[1][7] which would be a less expensive way to launch multiple warheads than deploying many ICBMs with single warhead payloads. The size and configuration of the 11-axle TEL indicates North Korea has developed a domestic capacity to manufacture such vehicles, a matter of concern to observers as attempting to block procurement of foreign-built TELs was one limitation on the nation's ICBM force. The country being able to produce their own launchers lifts that constraint and enables them to have the capacity to fire greater numbers of missiles.[8][9]

Since the Hwasong-15 was already capable of striking most of the contiguous United States, the development of an even larger missile suggests North Korea is pursuing MRV, or even MIRV, payloads. As of 2020, the Ground-Based Midcourse Defense system comprises 44 interceptors, requiring the launch of at least four to guarantee a hit, enabling it to protect against a maximum of 11 warheads. The Hwasong-17 may contain three or four warheads, or potentially a mix of decoys and real warheads, so the launch of just a few missiles would be enough to overwhelm U.S. defenses.[10][9] Despite posing such a threat, the missile is greatly limited by its sheer size. The combined weight of the missile and its TEL restricts movement to North Korea's limited network of paved roads, as it would only be able to travel short distances on unpaved roads and only on sturdy ground. Unlike smaller liquid-fueled ballistic missiles, it is unlikely that it can be fueled at a secure location and then driven to and erected at a pre-surveyed site to cut down on launch preparation time, as vibrations during movement of such a large missile would risk causing damage and leaking volatile fuel. This restricts fueling to once it arrives at the launch site itself, a process requiring several hours to complete, leaving the missile exposed and vulnerable to pre-launch attack. The Hwasong-17's multiple warhead capability is also speculative, as it requires complex guidance and warhead release mechanisms needing significant flight testing to ensure reliability, and no test launches had been conducted by the time of its public unveiling.[2]

On August 2021, commander of United States Northern Command Glen D. VanHerck stated that the "KN-28 missile has a much larger capability, and the total number of missiles tends to increase." This suggests that Hwasong-17 is designated as KN-28, not the KN-27.[11]

History[]

Test launches of the Hwasong-17 were carried out first on 26 February 2022, and again on 4 March. North Korea did not publicize news of the launches, with INDOPACOM revealing them later. The United States believed the tests were not intended to demonstrate the ICBM's range but conduct early evaluations of its capabilities.[12] North Korea publicly claimed the launches were intended to test components of a reconnaissance satellite at operational altitudes without disclosing they had been lofted by the new ICBM. It is possible the launches were done to test both satellite components and the ICBM, but only the former was admitted to limit potential international criticism.[13]
