Amid a flurry of military exercises by both Taiwan and China, Taiwan has been reportedly testing its domestically-made “Teng Yun” (Cloud Rider) UAVs. The Teng Yun is a medium-altitude long-endurance Unmanned Aerial Vehicle produced by the National Chung-Shan Institute of Science and Technology (CIST). The test took place near an Air Force base in sparsely populated Taitung County. One of the UAVs was recently spotted flying above the Zhihang Air Force Base. The aircraft, which resembled the U.S.-made Predator, was seen flying close to the fishing port of Fugang on several recent evenings.

Taiwan’s Air Force lost interest in purchasing the Teng Yun due to its electronic systems, the United Daily News quoted an expert as saying, according to taiwannews.com. But armyrecognition.com reports that the UAV is equipped with an electronic interference system developed by CIST that upgrades the UAV’s military strategic value from surveillance equipment to a multi-functional jamming device, capable of interfering enemies’ electronic surveillance systems.
