The Hwasong-19 is a three-stage, solid-fueled missile,
cold-launched on an 11-axle
transporter erector launcher. It appears to be larger than
its predecessor, as the missile uses a 11-axle TEL utilizing a unified hull-cover design. The canister cover is hinged at the bottom and fixed to the hull; while the cover open, it does not fall to the ground and remains connected to the TEL. This design may have been intended to save resources or to serve combat purposes, as well as to camouflage the mobile launcher as not launched to deceive the opponent. The missile's body is longer and wider than the
Hwasong-18, therefore, Hwasong-19 has more solid propellant than its predecessor, causing its flight time and apogee to increase by 13 minutes and , respectively. Its long range, which is estimated to be at least , allows it to reach targets anywhere in the
contiguous United States. Also, due to its increased diameter and heavier payload, Hwasong-19 can accommodate
MIRVs made in the 1960s. The Hwasong-19's length is estimated to be at least , longer than Hwasong-18 and
Russia's mobile ICBMs. However, its large size could limit its deployment area and mobility, making it vulnerable to detection by US and South Korean intelligence before it can be fired and making it a priority target for enemy's preemptive strikes. North Korea planned to use Hwasong-19 along with Hwasong-18 as its "primary core means in defending". It is possible that Hwasong-19 is intended to replace the liquid-fueled
Hwasong-17. Hwasong-19 is also claimed to be the world's largest operational road-mobile ICBM.
Modified version According to information released by North Korean state media in September 2025, the future modified version of Hwasong-19 will use a new solid-fueled engine, which produces a thrust of . This engine, which underwent eight static firing tests between 2023 and 2 September 2025, is also used by the newer
Hwasong-20. It has about 40 percent more thrust than the Hwasong-18 and can be modified to be used for reconnaissance satellite launches. ==History==
