North Korea’s missile engine test confirms the growing power of Pyongyang’s strategic arsenal. Made of carbon fiber, this solid propellant could equip future ICBMs capable of reaching the United States.
Pyongyang is ramping up pressure. North Korean leader Kim Jong-un witnessed a new test of a solid fuel missile engine as part of the country’s strategic arsenal development, announced the North Korean state agency KCNA on Sunday. Solid propellant engines offer high propulsive power and allow for faster launch procedures. According to experts, this engine is intended to equip the new Hwasong-20 intercontinental ballistic missiles (ICBMs) unveiled in October, aiming to reach the United States.
The test marks “Pyongyang’s determination to acquire missiles capable of reaching targets anywhere in the world,” noted analyst Hong Min from the South Korean Institute for National Reunification. The test, whose date and location were not specified, aligns with “the main objective of modernizing strategic strike capabilities,” as specified by KCNA, which states that the engine is made of a composite material based on carbon fibers.
In September 2025
According to this source, Kim Jong-un declared, while supervising the test, that North Korea’s defense capabilities had entered “an important phase of change.” North Korea’s nuclear and missile programs are subject to heavy UN sanctions. Pyongyang justifies them by citing threats from the United States and its allies, including South Korea. A previous test of this type of engine took place in early September 2025.
On March 14, Kim Jong-un and his daughter witnessed the firing of twelve 600mm multiple rocket launchers. Pyongyang claims these rockets can carry tactical nuclear warheads. A test in direct response to joint military exercises between the United States and South Korea. Kim described this weapon as a “massively effective means of destruction.”
