Hsinchu Air Base (ICAO: RCPO, IATA: HSZ) is a military airfield operated by the Republic of China Air Force, located in Hsinchu City on the northwestern coast of Taiwan. It serves primarily as a combat air base and is home to front-line fighter units responsible for defending Taiwan's airspace. The base is equipped to handle advanced jet aircraft and plays a strategic role in Taiwan's air defense posture given its proximity to the Taiwan Strait. Civilian commercial operations are not conducted at this facility, and public access is restricted. Hsinchu Air Base has historically hosted air shows and military demonstrations open to the public, offering rare glimpses of ROCAF aircraft and capabilities. The base is considered one of the key installations in Taiwan's layered air defense network.
