Deep Blue Aerospace on the month of forth week September 2026  Nebula-1 Y2 Development Progress | Thunder R2.0 Thrust Jumps to 30-Ton Class, First 200-Second Long-Duration Test Successfully Completed

Recently, DeepBlue Aerospace’s independently developed needle-plug reusable liquid oxygen-kerosene engine, “Thunder R2.0,” completed its power upgrade, increasing its thrust to the 30-ton class, and successfully completed its first 200-second long-duration test. The successful test of the Thunder R2.0 engine will accelerate the improvement of DeepBlue Aerospace’s complete reusable rocket and engine product portfolio, covering multiple scenarios and mission requirements. Based on this, DeepBlue Aerospace will continue to conduct reliability growth tests on the “Thunder” series engines, laying a solid foundation for achieving low-cost, high-frequency space transportation services.

The Thunder R2.0 engine, which powers the DeepBlue Space Nebula-1 Y2 rocket, has just completed a power upgrade, boosting its thrust to 30 tons and successfully completing its first 200-second long-duration test, allowing this rocket, which has not yet made its maiden flight, to directly enter a new stage.

I. Thunder R2.0 Core Upgrade Implemented, Achieving Breakthroughs in Both Thrust and Performance

• Thrust Significantly Increased : The Thunder R2.0 engine’s measured maximum thrust is close to 30 tons, a 50% increase compared to the first-generation model.
• Key parameter optimization : Engine chamber pressure increased from approximately 8 MPa to 10 MPa, and specific impulse performance improved by 10 seconds.
• The structure has been greatly simplified : the number of valves has been reduced by about 1/3, the overall weight has been reduced by about 25%, and the engine thrust-to-weight ratio has been increased from less than 80 to more than 150; the inner wall of the thrust chamber has been upgraded from steel to copper, and the after-processing process has been simplified.2

II. 200-second long-duration test, surpassing the threshold of actual launch load.

• Test nature : This test was the first 200-second long-duration test, which is equivalent to the engine burning continuously for 3 minutes and 20 seconds, fully simulating the intensity of a real launch, rather than a short-term ignition verification.
• Significance of the test : The successful test will accelerate the improvement of DeepBlue Aerospace’s capabilities to meet the needs of multiple scenarios and missions

The Nebula-1 is a medium-sized liquid-fueled reusable launch vehicle independently developed by DeepBlue Aerospace. Currently, the development of its second remote sensing version is underway. Recent key developments are as follows:

Engine Upgrade: Thunder R2.0 Completes First 200-Second Long-Distance Test

DeepBlue Aerospace’s independently developed needle-type reusable liquid oxygen-kerosene engine, “Thunder R2.0,” has completed a power upgrade, with its thrust jumping from the initial 20-ton level of the Thunder R1 to the 30-ton level, and successfully completed its first 200-second long-duration test. Key achievements of this test include: a measured maximum thrust of nearly 30 tons, a 50% increase compared to the first generation; an increase in engine chamber pressure from approximately 8 MPa to 10 MPa, improving specific impulse performance by 10 seconds; a significantly simplified engine structure, reducing the number of valves by about one-third, reducing overall engine weight by about 25%, and increasing the thrust-to-weight ratio from less than 80 to over 150; and an upgrade to a copper inner wall for the thrust chamber, with simultaneous process optimization.

Rocket overall parameters and positioning

The Nebula-1 rocket is approximately 30.2 meters long, has a ground thrust of about 180 tons, and a low Earth orbit payload capacity of about 2 tons. It is positioned as a mainstay commercial launch vehicle for high-frequency missions, targeting small and medium-sized satellite operators, research institutions, and other customers, meeting the needs of rapid networking of small and medium-sized satellites and constellations. The long-term design goal is to increase the thrust of a single engine to the 35-40 ton range and to enable the rocket to be reused 50 times.

Historical Background and Future Prospects

Previously, during its first high-altitude vertical recovery flight test, the Nebula-1 rocket experienced an anomaly during the final landing phase, resulting in a less than successful test. DeepBlue Space has continued its development since then, and in April of this year, Nebula-1 entered the launch site to complete integrated launch and propellant loading system training. The fact that the second version is directly equipped with an upgraded engine indicates that DeepBlue Space is accelerating its technological iteration and striving to achieve its maiden flight as soon as possible.

III. With “Yao-2” taking the lead, the overall development of Nebula-1 has entered the final sprint stage.

• Iteration strategy : In version 1
• Rocket parameters : The Nebula-1 is about 30.2 meters long. It adopts a two-stage configuration and uses a combination of liquid oxygen and kerosene propellants. The first stage is equipped with nine Thunder R-series engines in parallel. Its low Earth orbit payload capacity is about 2 tons.
• Development progress : The first and second stage core power units of the rocket have passed key tests and assessments, and have entered the full sprint stage of the first flight mission. Previously, the parallel test of the nine engines of the first stage power system was completed and the multi-engine collaborative working capability was verified.

The satellites successfully entered their predetermined orbits, and the launch mission was a complete success. This mission marked the 16th flight of the Lijian-1 carrier rocket

 [Lijian-1 Y18 Carrier Rocket Successfully Launches 9 Satellites] At 12:03 PM on September 20, 2026, the Lijian-1 Y18 carrier rocket, carrying the “Supercomputing” satellite, was launched from the Dongfeng Commercial Aerospace Innovation Test Zone. Using a “one rocket, nine satellites” approach, it accurately sent nine satellites, including “Supercomputing-1,” into their predetermined orbits. The launch mission was a complete success. These satellites will be primarily used for space environment monitoring, disaster prevention and mitigation, and scientific experiments.

This mission employed a multi-satellite launch mode, accelerating the construction of a small satellite constellation. Multi-satellite coordinated launches place stringent standards and higher requirements on key technologies such as overall satellite-rocket layout matching, payload interface compatibility, and precise control of multi-satellite separation timing. Relying on a mature and complete multi-satellite overall design system and high-precision satellite-rocket separation control technology, the Lijian-1 carrier rocket successfully completed the safe, orderly, and precise deployment of multiple satellites into orbit, fully demonstrating the rocket’s excellent mission adaptability and engineering reliability.

Currently, the LiJian-1 launch vehicle has a sufficient order backlog and strong market demand, with launch missions scheduled until the second half of 2027. The LiJian-1 has demonstrated stable and efficient performance in high-density launch scenarios, thanks in no small part to the comprehensive R&D, testing, production, and launch capabilities of CAS Space. Ample order backlog, a clear mission schedule, and robust production capacity provide a solid foundation for the LiJian-1 to continuously expand its market reach and steadily evolve towards large-scale, frequent launches of commercial rockets.

This mission marks the 16th flight of the LiJian-1 launch vehicle and the 17th launch of the LiJian series. To date, the LiJian series has successfully launched one spacecraft and 121 satellites into space, with a total payload exceeding 21 tons. CAS Space is the commercial aerospace company in China with the largest number of satellites launched and the heaviest payload.
