The Hwasong-12B () is a North Korean single-stage, liquid-fueled hypersonic, intermediate-range ballistic missile. Unveiled in July 2023 during a military exhibition, Hwasong-12B is the second North Korean ballistic missile capable of carrying hypersonic glide vehicle (HGV) after Hwasong-8, as well as the third hypersonic missile of North Korea.
The Hwasong-12B is a single-stage missile, powered by a liquid-propelled engine, carried by 6-axle transporter erector launchers. Although Hwasong-12B has never undergone flight testing, its range is estimated to be over .
The hypersonic glide vehicle (HGV) of Hwasong-12B is simillar in shape to the vehicle used by the solid-fueled Hwasong-16B. It is likely mounted on a shortened, or a standard Hwasong-12 booster. Compared with Hwasong-8, the HGV of Hwasong-12B has some differences in fuselage and control fins. It is the second ballistic missile of North Korea capable of carrying hypersonic glide vehicle (HGV) after Hwasong-8 (launched in September 2021), and the third type of hypersonic missile overall after it and Hwasong-12A (tested in January 2022).
North Korea first test-fired missile with hypersonic glide vehicle in September 2021, with Hwasong-8. According to German analyst Norbert Brügge, North Korea displayed two types of hypersonic glide vehicle (HGV) in a military parade on 25 April 2022.
Hwasong-12B made its public debut on 26 July 2023, during a military exhibition. At the time of debut, a bilingual information board in Korean and English was displayed to Kim Jong Un and Sergei Shoigu with official name. The next day, North Korea displayed four Hwasong-12B missiles at a military parade.
It is possible that the Hwasong-12B was renamed from Hwasong-8 between September 2021 and July 2023. However, it seems unlikely, as the Hwasong-8 may be the name of the prototype hypersonic missile, and Hwasong-12B is planned to be the operational product. Although there has been no known test for Hwasong-12B so far, at least two Hwasong-12B missiles were spotted in October 2024 during Kim Jong Un's visit to a missile base, suggesting that the missile may be deployed without any flight testing.
