What’s New in ZQ-2E Y5? • Increased propellant capacity & structural optimization The EXTENDED first-stage tanks, combined with full subcooled propellant loading, increased propellant capacity by ~15%. Structural mass is further reduced through partial insulation removal, optimized cable routing fairings, and removeal of first-stage fins, reflecting a system-level design optimization approach. • Three-ignition second stage with high-orbit disposal ZQ-2E Y5 pioneers, among China’s commercial missions, a three-ignition second-stage flight profile featuring tank-pressure ignition + high altitude deorbit. This approach ensures ignition reliability while enabling rapid high-altitude deorbit, addressing traditional challenges and supporting space debris mitigation requirements. • Toward “Smart Launch Vehicles” The first stage introduces in-flight engine anomaly detection and thrust self-correction, while the second stage debuts a propellant utilization system. These enable autonomous diagnosis and response to off-nominal conditions (e.g., thrust deviation, mixture ratio shifts), significantly improving flight reliability and service capability. • Rapid launch capability Leveraging mature mission operations, the campaign achieved a 13-day launch cycle and ~1.5-hour pre-launch fueling timeline, laying the foundation for high-frequency launch operations with both ZQ-2E and ZQ-3.
