(ECNS) -- China's self-developed solid rocket engine, with a diameter of 3.5 meters and a maximum thrust of 500 tons, concluded its test run successfully in Xi'an, Shaanxi Province.

Backed by a number of cutting-edge technologies such as high-pressure overall design and the high-performance fiber composite shell, it is the most powerful solid rocket engine with the largest thrust in the world so far.

The Fourth Research Institute of China Aerospace Science and Technology Corporation (CASC), the developer of this engine, said the successful test run marks a substantial improvement to the payload of China's solid propellant rockets and is of great significance in promoting the development of the country's large and heavy rockets.
