The Hwasong-18 is North Korea's first solid-fuel ICBM — cold-launched, road-mobile, three-for-three in 2023 tests, with an implied 15,000 km reach covering the entire US. It compresses pre-launch warning to minutes and sparked an unresolved fight over Russian design help.
The KN-25 is North Korea's 600mm "super-large" rocket launcher — the world's biggest-caliber guided rocket artillery, a rocket/ballistic-missile hybrid reaching 380 km, nuclear-tasked and mass-produced. Despite two years of reports, no transfer to Russia has ever been confirmed.
The M1989 Koksan is North Korea's 170mm self-propelled gun — the largest-caliber tube artillery in service anywhere, built to range Seoul. Since late 2024 Pyongyang has shipped 120–200 to Russia, where they now fire on Ukrainian lines and are being hunted by drones and HIMARS.
