Aerial bombardments weighed heavy on the minds of Chinese military planners in the taut decades of the Cold War, and protecting their fledgling jet fleet was of paramount importance.
To keep their planes and equipment from the prying eyes of satellites, and the earth shattering bombs of an aerial attack, China built an elaborate set of underground bunkers.
Sean O'Connor and Dr. Carlo Kopp from Air Power Australia published a monograph on China's underground air bases, and what it would take to bring them down may surprise you.
China began construction of its 40 or so hidden bases in the 1950s, and though some have fallen out of military use and are open the public as museums many are harboring China's newest military might.
Attacking anything like this requires a unique approach.
China has over 40 of these underground hangars it started building in the 1950s
