Deep Blue Aerospace has recently announced the successful execution of a 100-second sustained hot fire test for its 130-ton-class liquid oxygen and kerosene engine, dubbed the "Thunder-RS." This engine serves as the primary propulsion system for the "Nebula-2" rocket. During the test, the engine demonstrated a remarkable thrust of 1,297.5 kilonewtons, with all operational parameters aligning precisely with the design specifications.

This milestone test not only validated the engine's overall reliability but also confirmed the exceptional thermal protection capabilities of its thrust chamber. It signifies a major technological leap forward for China's most potent gas-generator-cycle pintle-injected liquid oxygen and kerosene engine. Moreover, it underscores the continued progress in domestic commercial aerospace technology, particularly in the realm of high-thrust rocket engines.
