Iran’s subterranean labs have made news lately, but it’s China’s bunkers and reinforced underground hangars that have been on the minds of Western military planners for generations.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 air fleet.
Coming at the bunkers with bombs aimed at “the front door” likely won’t do much to take structures like this out.
The problem with bunker buster bomb delivery is that any good bunker will have a highly reinforced outer lip to detonate the bomb before it penetrates too far into the rock
Because of the way the bunkers are built, the energy from a traditional strike will be absorbed by the roof and the excess load will spill from the sides into the surrounding rock
The shock waves would likely buckle the floor and skew the tensile load, buckling the ceiling as well
But there's no guarantee. And the US has only a handful of MOP bombs. If it uses them it won't likely be on Chinese hangars.
