Low-Profile Chinese Launch Firm Conducts First Stage Static Fire

Why It Matters

The test validates a new Chinese commercial launcher and advances the nation’s push toward reusable, cost‑effective access to orbit, intensifying competition in the global launch market.

Key Takeaways

• Zenk Space completed Zhihang-1 first-stage static fire.
• Rocket aims 4,000 kg payload to 500 km SSO.
• Uses four CASC‑developed YF‑102 kerolox engines.
• Partial engine recovery planned via parachutes and airbags.
• ZH‑2 and ZH‑3 target larger payloads and full reuse.

Pulse Analysis

China’s commercial launch ecosystem is gaining momentum, and Zenk Space’s recent static‑fire test marks a tangible step forward for the sector’s lesser‑known players. Conducted on February 11 from the HOS‑1 mobile sea platform off Shandong, the test verified the first stage of the 50‑metre Zhihang‑1 vehicle after months of ground‑level qualification. By confirming engine ignition and thrust stability, Zenk Space signals that the rocket is ready to move from laboratory validation to an orbital flight, joining a wave of new Chinese launchers slated for debut in 2026.

The Zhihang‑1 is powered by four YF‑102 kerolox engines, a gas‑generator cycle design originally supplied by the state‑run China Aerospace Science and Technology Corporation and already proven on Tianlong‑2 and Kinetica‑2. With a 3‑stage architecture and a 3.35‑metre diameter, the vehicle can lift roughly 4 tonnes to a 500‑kilometre sun‑synchronous orbit, positioning it for small‑sat constellations and Earth‑observation missions. Zenk Space’s recovery concept focuses on retrieving the engine bay after stage separation, using thermal protection, parachutes and buoyant airbags to enable refurbishment and future reuse.

Beyond the technical milestone, the test underscores China’s broader push toward reusable launch services, a trend that could reshape global launch economics. Zenk Space’s roadmap includes the larger 62‑metre ZH‑2, capable of 12 tonnes to SSO, and the 81‑metre ZH‑3, which aims for full first‑stage recovery. As state‑backed programs like Long March 10A and private competitors such as Galactic Energy and Space Pioneer race to operational status, Zenk’s progress adds depth to a market that is increasingly attractive to international satellite operators seeking cost‑effective access to orbit.
