Zhuque-2E is the enhanced operational Zhuque-2 configuration. It stretches the vehicle to 55 metres, increases liftoff mass and thrust, replaces the baseline engines with four TQ-12A first-stage engines and one restartable vacuum TQ-15A upper-stage engine, and can deliver up to 6,000 kilograms to low Earth orbit or 4,000 kilograms to a 500-kilometre sun-synchronous orbit.
