With the recent launches of the Yaogan 26 and Yaogan 27 satellites China has demonstrated its ability to routinely identify, locate and track an Aircraft Carrier Group (ACG) on the high seas. This space capability is an important component of an Anti-Ship Ballistic Missile (ASBM) System that China has set up.
The current operational satellite constellation consists of ELINT satellites, satellites carrying Synthetic Aperture Radar (SAR) sensors as well as satellites carrying optical imaging sensors.
Based on the orbit characteristics, their local time of equatorial crossing and other related parameters, these satellites can be grouped into different categories that perform the various functions for identifying, locating and tracking the ACG.
Yaogan 9 (Yaogan 9A, 9B, 9C), Yaogan 16 (16A, 16B, 16C), Yaogan 17 (17A, 17B, 17C), Yaogan 20 (20A, 20B, 20C) and Yaogan25 (25A, 25B, 25C) are the five triplet cluster equipped with ELINT sensors that provide broad area surveillance over the Oceans. With a coverage radius of about 3500 Km, they provide the first coarse fix for identifying and locating an ACG in the Pacific Ocean. Yaogan 20 and Yaogan 25 may be replacements for the Yaogan 9 and the Yaogan 16 that may be nearing the end of their lives.
