North Korea's Evolving Arsenal: A Timeline of Advanced Weapons.

North Korea has made significant advancements in its missile technology, making its arsenal of missiles easier to launch, harder to track, and capable of carrying nuclear warheads. Recent developments include the launch of a solid-fuel intercontinental ballistic missile, the Hwasong-18, and the ability to launch missiles from underground. North Korea is also experimenting with submarine-launched missiles and is preparing to launch its first military reconnaissance satellite. However, the country has not yet proven its ability to miniaturize nuclear warheads to mount on tactical weapons aimed at South Korea or Japan.
