From the Washington Post:
The Chinese have called it their “Underground Great Wall” — a vast network of tunnels designed to hide their country’s increasingly sophisticated missile and nuclear arsenal.
For the past three years, a small band of obsessively dedicated students at Georgetown University has called it something else: homework.
Led by their hard-charging professor, a former top Pentagon official, they have translated hundreds of documents, combed through satellite imagery, obtained restricted Chinese military documents and waded through hundreds of gigabytes of online data.
The result of their effort? The largest body of public knowledge about thousands of miles of tunnels dug by the Second Artillery Corps, a secretive branch of the Chinese military in charge of protecting and deploying its ballistic missiles and nuclear warheads.
The study is yet to be released, but already it has sparked a congressional hearing and been circulated among top officials in the Pentagon, including the Air Force vice chief of staff.
Most of the attention has focused on the 363-page study’s provocative conclusion — that China’s nuclear arsenal could be many times larger than the well-established estimates of arms-control experts.
“It’s not quite a bombshell, but those thoughts and estimates are being checked against what people think they know based on classified information,” said a Defense Department strategist who would discuss the study only on the condition of anonymity.
