North Korea has conducted a test of a new rocket engine that could potentially be used for an intercontinental ballistic missile capable of reaching the U.S. mainland, according to state media reports. The test was supervised by North Korean leader Kim Jong Un and is seen as the latest step in the country's ongoing weapons development program.

Why it matters

North Korea's missile and nuclear weapons programs have been a major source of tension with the United States and its allies in the region. This latest test suggests the regime is continuing to make progress on developing a reliable ICBM that could threaten the U.S. homeland, ratcheting up concerns about the potential for conflict on the Korean peninsula.

The details

State media reported that the test was conducted at the Sohae Satellite Launching Ground and involved a new type of 'high-thrust engine' that would be used for North Korea's 'strategic' long-range rockets. The engine was said to have performed well during the test, which Kim Jong Un observed and described as a 'great success' that would enable the country to launch 'large-size heavy satellites'.

  • The engine test was conducted on March 18, 2026.
