By mid-May 2021, the People’s Liberation Army (PLA) likely began construction of a potential intercontinental ballistic missile (ICBM) silo site in Hanggin Banner, Ordos City, Inner Mongolia (approximately at 40.113, 108.104). Images taken by the European Space Agency’s Sentinel-2 mission between 16 May and 9 August 2021 reveal a construction footprint similar to those found at known PLA ICBM silo construction sites at Jilantai, Guazhou (typically referred to as the Yumen site), and Hami.
