A 220-ton rocket engine roaring on a test stand may sound routine. Yet this latest Landspace firing signals a quiet race to redefine Next-Gen Rocket Technology and who dominates reusable Heavy-Lift Rockets in the 2030s.
Behind the flames, an entire strategy for Space Exploration and satellite megaconstellations is taking shape in China’s private space sector.
Landspace’s 220-ton methane engine raises the stakes
The Chinese startup has confirmed a successful long-duration Rocket Engine Test of its new BF “Blue Flame” powerplant, a Methane Engine delivering roughly 220 metric tons of thrust. This full-flow staged combustion (FFSC) design runs on liquid methane and liquid oxygen, a combination often called Methane Propulsion or “methalox.”

According to reports such as coverage dedicated to the BF test campaign, this trial followed more than 100 integrated ignitions since the first full-system hot fire in May 2025. The new run focused on long-duration stability, validating how the pumps, preburners, and main combustion chamber behave when pushed together for extended periods.
From Zhuque-3 landing failure to heavy-lift ambition
The context explains why this firing matters. In late 2025, Landspace attempted China’s first orbital booster recovery with its stainless-steel Rocket Launch vehicle Zhuque-3. The second stage, carrying a mass simulator, reached orbit, but the first stage failed shortly after the landing burn ignition.
Rather than pausing, the team doubled down. A new recovery attempt is scheduled for the second quarter, with a target to demonstrate reuse before year-end. While engineers refine reentry and landing, the BF engine is being readied as the core propulsion element for larger, more powerful boosters aimed at heavy payloads and frequent commercial missions.
Why this full-flow methane propulsion is a big deal
The BF engine’s architecture mirrors the most advanced approaches in Aerospace Engineering. Full-flow staged combustion sends both oxidizer-rich and fuel-rich gas through separate turbines, driving the turbopumps before everything mixes in the main chamber. This achieves higher efficiency, higher chamber pressure, and improved reuse margins compared with traditional open cycles.
SpaceX’s Raptor proved how this method can support heavy, partially reusable systems. Chinese media, including detailed pieces like recent reports on China’s breakthrough in methalox engines, present BF as part of a broader national push toward high-performance liquid engines. The challenge lies in the complexity: multiple preburners, high internal pressures, and brutal thermal loads demand precise control across all regimes.
Key advances validated during the rocket engine test
During the latest campaign, Landspace focused on integrated behavior rather than maximum numbers. Engineers monitored how the engine handled prolonged operation, throttling transitions, and start–stop sequencing. Even though exact duration and thrust levels were not disclosed, the company states that system maturity and reliability have significantly improved.
The test demonstrated progress in areas that often doom FFSC projects: turbopump sealing, combustion stability at high pressure, and thermal management of hot gas paths. Each resolved issue moves the BF unit from experimental prototype toward a workhorse stage engine for Heavy-Lift Rockets.

New heavy-lift rockets and China’s wider space strategy
The engine will not operate in isolation. Landspace already flies Zhuque-2 and is developing more capable variants of Zhuque-3 to serve large constellations, including batches for the national Guowang broadband network. Stacking multiple BF engines in clustered first stages opens the door to fully commercial heavy-lift vehicles.
The company’s growth is financial as well as technical. Its application for a public listing on Shanghai’s STAR Market was accepted in late 2025, with an estimated raise around one billion dollars. That potential funding would support expanded test infrastructure, serial production, and development of recovery systems tuned for methalox boosters. Related advances in the industry are echoed in webb telescope gamma ray burst.
Competition and collaboration in next-gen rocket technology
On the state side, CASC is working on its own FFSC engine family, sometimes referred to as YF-215, for future Long March 9 super heavy-lift launchers. Commercial rival Space Pioneer has also signaled plans for FFSC designs, while younger players such as Welight and Arktech are circulating conceptual studies.
This ecosystem resembles a technological “scrimmage” where multiple teams iterate on Propellant Innovation. The government’s draft 15th Five-Year Plan highlights reusable heavy-lift systems as a priority, tying them directly to goals like satellite internet coverage and a long-term lunar research base. In that context, every successful BF firing strengthens Landspace as a candidate supplier for national missions.
What this means for future space exploration missions
Imagine a future lunar logistics chain using methalox boosters for the climb from Earth and potentially methane sourced off-world for refueling. High-performance Methane Propulsion becomes more than a lab achievement; it turns into an infrastructure enabler for deep Space Exploration and cislunar transport.
For satellite operators, heavier reusable rockets powered by engines like BF could push down per-kilogram launch prices while increasing cadence. That mix reshapes business models, from Earth-observation fleets that track climate impacts to energy research. Similar innovation is happening on the ground, where researchers explore ways to transform exhaust gases or methane itself into higher-value products, as seen in work on converting CO₂ or even turning methane into medical compounds.

How engineers and fans can follow the BF story
For those following every test firing, detailed breakdowns of the campaign, high-speed footage, and technical interpretations circulate across specialist outlets and social platforms. Analyses by communities focused on Next-Gen Rocket Technology and reusable systems help decode what each static fire reveals.
Some sources, like the in-depth briefs from Friends of NASA or other observers, trace the evolution from the first hot fire in May 2025 to more than one hundred ignitions today, providing a step-by-step record of how a prototype transforms into a flight-ready engine family prepared for clustered use on future heavy-lift missions.

What makes Landspace’s BF methane engine different from traditional rocket engines?
The BF engine uses a full-flow staged combustion cycle with liquid methane and oxygen. Both propellants pass through preburners to drive turbopumps before entering the main chamber. This approach improves efficiency, thrust-to-weight ratio, and potential reuse compared with open-cycle kerosene engines, making it better suited for future heavy-lift reusable rockets.
How powerful is the BF engine and what will it be used for?
The BF engine is designed to deliver about 220 metric tons of thrust. Landspace plans to use it as a core propulsion element for next-generation large and heavy-lift launch vehicles, likely in clustered configurations on first stages. These rockets aim to carry big satellite batches, deep-space payloads, and potentially future lunar infrastructure modules.
How does this engine support reusable heavy-lift rockets?
Methane burns cleaner than kerosene, reducing soot and thermal stress inside the engine. Combined with the full-flow staged combustion design, this allows more start–stop cycles and longer life. Those traits are vital for boosters that must survive multiple flights, controlled reentries, and landing burns while still delivering reliable performance on every rocket launch.
Where can I find more technical details about the BF engine tests?
Specialist space outlets and technical communities regularly publish analyses of Landspace’s test campaign. Articles summarizing the long-duration full-system hot-fire, as well as public test footage and discussions of performance targets, provide additional insight into chamber pressure, ignition sequences, and clustering strategies for future heavy-lift rockets.
How does Landspace fit into China’s broader space ambitions?
Landspace is part of a fast-growing commercial ecosystem that complements state-owned programs like CASC. By developing advanced methalox engines and reusable launchers, the company supports national goals such as satellite internet constellations and lunar research stations, while competing for commercial contracts and investment on a global aerospace engineering stage.
