Yun Feng Development
Following the 1996 Taiwan Strait Crisis, Taiwan began developing the Yun Feng missile in secret, concealing flight tests within the Hsiung Feng III test program to avoid public scrutiny. Media reports of the missile program surfaced much later in December 2012. The missile was developed by the National Chung-Shan Institute of Science and Technology (NCSIST).2
The Yun Feng’s extended range had made it controversial among Taiwan analysts. Analysts caution that the missile is inappropriate given Taiwan’s defensive posture and China’s advanced air defense capabilities, and could negatively impact Taiwan’s relations with the United States.3
Taiwan reportedly flight-tested the Yun Feng along with various other missiles and rockets in April 2020.4
The standard Yun Feng is believed to have a range of 1,200 km, but an extended version also in development has a reported range of 2,000 km.5 The missile uses a ramjet engine which allows it to travel at supersonic speeds, reportedly reaching a maximum of 1,030 m/s.6
The Yun Feng became operational in 2014. NCSIST reportedly began producing a first batch of 20 missiles and 10 mobile launchers in August 2019.7
