LandSpace’s Zhuque-3 Y2 Passes Full-Stack Test, Eyes July Launch Window

LandSpace announced on June 29 that it has successfully completed a full-stack static fire test of its reusable Zhuque-3 Y2 launch vehicle at the Dongfeng Commercial Aerospace Innovation Test Zone, marking the final and most critical ground verification milestone before flight.

The company said all systems performed stably throughout the test, with core performance parameters meeting design specifications. The static fire test — which simulates actual launch conditions on the ground — conducted a full-chain integrated validation of the rocket's propulsion cluster, airframe structure, electrical control systems, and launch support infrastructure. The exercise verified thrust stability during simultaneous multi-engine ignition, structural load-bearing capacity, and the coordination between the rocket and ground systems.

With the completion of this test, LandSpace confirmed that all key ground verification work for the Zhuque-3 Y2 has been closed out, and the rocket is now technically qualified to execute its reusable flight and recovery demonstration mission.

A June launch, however, is no longer feasible. With only one day remaining in the month at the time of the announcement, the timeline is insufficient to accommodate the full pre-launch sequence — including comprehensive data review, vehicle status inspection and reset, full launch rehearsal, and propellant loading preparations. Based on standard post-static-fire procedures, which typically require one to two weeks for data consolidation and final launch site readiness, the launch window for Zhuque-3 Y2 is expected to fall in July 2026.

The Zhuque-3 Y2 mission is designed to validate the rocket's reusability and recovery capabilities, a key step in LandSpace's broader ambitions in the commercial launch market.
