Zhuque-2 Improved Y5 Launch a Complete Success – LandSpace’s Zhuque-2 Improved Y5 Launch Vehicle Successfully Launched] At 11:00 AM Beijing time on May 13, 2026, the Zhuque-2 Improved Y5 launch vehicle (ZQ-2E Y5) was successfully launched from LandSpace’s liquid oxygen-methane launch pad in the Dongfeng Commercial Aerospace Innovation Test Zone ,Inner Mongolia, China, People’s Republic of China. . The launch successfully completed all flight procedures.



The ZQ-2E Y5 is a two-stage cryogenic extended liquid-fueled launch vehicle developed through systematic iterative design, fully inheriting the mature technologies of previous launches. This mission reached an orbital altitude of 900 kilometers and carried a 2.8-ton customized experimental payload for large-scale satellite constellation deployment. This signifies that the ZQ-2E model has achieved breakthroughs in heavy payload launch capabilities, possessing the engineering conditions to undertake multi-satellite launch missions. It provides mature and reliable launch capability support for implementing the goals of building a new pillar industry of “aerospace” and accelerating the development of “satellite internet” as outlined in this year’s Government Work Report, as well as for subsequent large-scale satellite constellation deployment projects.
The ZQ-2E Y5 rocket has a diameter of 3.35 meters, a maximum fairing diameter of 4.2 meters, and a total length of approximately 55.9 meters. Its liftoff mass is 267 tons (excluding payload), and its liftoff thrust is 338 tons. The first stage uses four TQ-12A liquid oxygen-methane engines in parallel, each with a sea-level thrust of 828 kN, with each engine’s thrust increased by 108 kN and a new thrust self-correction function added. The second stage uses TQ-15A liquid oxygen-methane engines with a vacuum thrust of 858 kN. The ZQ-2E Y5 primarily utilizes techniques such as lengthening the first stage, increasing propellant loading, reducing structural weight, and increasing the thrust of the first-stage engines to further release and optimize the rocket’s carrying capacity, significantly improving its overall performance and enhancing its launch service capabilities for a multi-orbit mission spectrum.
The allure of spaceflight lies not only in its technological sophistication but also in the social value it embodies. During mission preparation, LandSpace specially invited teachers and students from Huanggu Experimental School in Pinghu City to the launch site to observe rocket operations and interact with Qiu Jingyu, the chief designer of the ZQ-2E model. Today, the teachers and students also watched the rocket launch with engineers at LandSpace’s Jiaxing base. Since 1992, teacher Yao Aiying from the school has led students to send letters and donate money to support the aerospace industry, proposing the slogan “Don’t chase pop stars, chase science stars,” continuously sowing the seeds of aerospace dreams for 34 years. In the countdown to launch, this cross-generational support and encouragement quietly took root in the hearts of a generation of young people.








The ZQ-2E Y5 is the maiden flight product of the improved and extended version of the Zhuque-2. This model has achieved a payload capacity of 4 tons to a 500-kilometer sun-synchronous orbit and 6 tons to a low Earth orbit, making it one of the leading models in terms of payload capacity among currently operational medium-sized liquid-propellant launch vehicles in China’s commercial aerospace sector. It can flexibly adapt to diverse mission requirements such as launching multiple satellites with a single rocket and deploying large-capacity payloads. It can also form a combined launch service solution with the ZQ-3 reusable launch vehicle, enhancing China’s ability to ensure large-capacity, low-cost, and high-frequency access to space .

【Zhuque-2 What Evolutions Have Been Made?】The improved Zhuque-2 Y5 carrier rocket (ZQ-2E Y5) features a lengthened first-stage propellant tank combined with fully supercooled fueling technology, increasing propellant capacity by approximately 15%. Simultaneously, weight reduction measures such as eliminating part of the first-stage tank’s insulation layer, optimizing the cable array layout, and removing the first-stage tail fins have achieved systematic structural weight reduction, reflecting the systems engineering thinking in the rocket’s overall design.


In domestic private space missions, the ZQ-2E Y5 pioneered a second-stage, three-ignition “tank pressure ignition + high-orbit deorbiting” technical solution. Utilizing engine tank pressure ignition and the passivation force of the final stage, it achieves rapid high-orbit deorbiting, effectively solving the traditional high-orbit deorbiting problem while ensuring ignition reliability. This responds to national requirements for rocket final-stage deorbiting and space debris mitigation, protecting valuable space orbit resources.
The ZQ-2E Y5 rocket pioneered online engine fault diagnosis and self-correction technology in its first stage and applied a propellant utilization system for the first time in its second stage. This system can automatically diagnose and respond to conditions such as low engine thrust and excessive mixture ratios during flight, significantly improving flight reliability and launch service capabilities, and propelling launch vehicles steadily towards becoming “smart rockets.”
Based on mature mission process design experience, this mission achieved a breakthrough in rapid launch capability with a test and launch cycle of 13 days and a pre-launch propellant loading process of 1.5 hours, fully preparing the ZQ-2E and ZQ-3 launch vehicles for high-frequency missions.
