Companion satellite to Tianhui 6A, completing the sixth Tianhui formation-flying pair. The relentless cadence of new Tianhui generations — six major iterations in roughly a decade — demonstrates a level of sustained institutional commitment that few nations apply to military topographic mapping, a capability area that rarely generates headlines but underpins nearly every other military operation from missile guidance to logistics planning.
