Following what became a historic countdown, PLA Sergeant Major Zhao Jing tapped the laptop before him, declared “launch sequence initiated”, and exited the cabin of the missile vehicle he had ridden into the dense jungle of Hainan province.
Some 27 minutes later, a dummy warhead plunged into the southern Pacific Ocean in an uninhabited area near French Polynesia, thousands of miles from Hawaii.
The moment on September 25, 2024, marked China’s first full-range, trans-Pacific intercontinental ballistic missile (ICBM) test since 1980 – and only the second in the country’s history.

In the launch tied to “the honour of the Rocket Force and the dignity and confidence of the nation”, what Zhao activated was a DF-31AG missile.
