Long March 7

01

Current status

Operational from Wenchang since 2016, providing routine Tianzhou cargo resupply for China's crewed program; a Long March 7A variant delivered the Tianlian III-01 relay satellite on July 29, 2026, Wenchang's 50th launch. On August 10, 2026 a Long March 7A broke apart about 85 seconds after liftoff carrying the Zhongxing-4B satellite - the variant's second failure ever, after its March 2020 debut - triggering a mandatory investigation into the shared YF-100 kerolox engine that also powers the Long March 5, 6, 8, 10, and 12 families. As of September 14, 2026 CASC has still not announced a root cause or a 7A return-to-flight date. Other Long March variants have continued flying: a Long March 5B (Aug 13), Long March 12 (Aug 16), Long March 6C (Aug 25, the 665th cumulative mission), and the 666th on September 10 (a hypergolic Long March 4B from Jiuquan, not a YF-100 vehicle).
