Some of the most visible features at each of China’s newly-discovered probable missile silo fields are the environmental shelters that cover each suspected silo headworks. We first describe the shelters, then what we see under the shelters, unique support facilities, and end with overall observations. In this article we describe the progress we have observed. In recent analysis of new satellite images obtained from Planet Labs and Maxar Technologies, we have observed almost weekly progress in construction of suspected silos as well as discovered unique facilities that appear intended to support missile operations once the silo fields become operational. Yet our analysis of hundreds of satellite images over the past three years of the suspected missile silo fields and the different facilities that are under construction at each of them have increased our confidence that they are indeed related to the PLARF’s modernization program. In this article we use words like suspected, apparent, and probable to remind the reader of that fact. The Chinese government has still not officially confirmed or denied that the facilities under construction are silos intended for missiles and there are many uncertainties and unknowns about the nature and role of the facilities.

The images provide a vivid and rare public look into what is otherwise a top-secret and highly sensitive construction program. After the discovery during the summer of what appears to be at least three vast missile silo fields under construction near Yumen, Hami, and Ordos in north-central China, new commercial satellite images show significant progress at the three sites as well as at the People’s Liberation Army Rocket Force (PLARF)’s training site near Jilantai.
