The US Department of Defense has stated that China has developed and reached initial operating capability of a conventionally-armed high hypersonic land-based anti-ship ballistic missile (ASBM) based on the DF-21. This would be the world's first ASBM and the world's first weapons system capable of targeting a moving aircraft carrier strike group from long-range, land-based mobile launchers. These would combine maneuverable reentry vehicles (MaRVs) with some kind of terminal guidance system. Such a missile may have been tested in 2005-6, and the launch of the Jianbing-5/YaoGan-1 and Jianbing-6/YaoGan-2 satellites would give the Chinese targeting information from SAR (Synthetic Aperture Radar) and visual imaging respectively. The upgrades would greatly enhance China's ability to conduct sea-denial operations to prevent US carriers from intervening in the Taiwan Strait. A professor at the U.S. Naval War College says that carrier-killing missiles underscore that the U.S. can no longer assume naval supremacy as it has since the end of World War II.
China has recently launched a series of satellites to support its ASBM efforts:
