China Space News says in its report “Maiden flight of Changzheng-5 rocket will be conducted in the latter half of this year to increase Chinese rocket’s loading capacity 2.5 folds” that China’s new Changzheng-5 (CZ-5) carrier rocket able to carry 2.5 times more load than its best rocket so far has been assembled and passed comprehensive tests on the ground. It will be launched for the first time in the next half of 2016.

According to the report, CZ-5 can carry 25 tons load to near earth orbit and 14 tons to geosynchronous orbit more than 2.5 times heavier than that its rocket in service can carry.

It has 8 newly developed liquid oxygen-kerosene engine with a thrust of 120 tons each, giving the rocket a total takeoff thrust of 1060 tons. The greatest thrust of one engine in China’s rockets in service is only 70 tons. Its takeoff mass is about 878 tons.

The rocket uses almost 100%, i.e. 247 items of new key technology while new rocket in the world generally only adopts less than 30% new technology. Moreover it has a designed reliability of 0.98 higher than the best reliability of 0.97 Chinese rockets have achieved.

The rocket, if succeeds in its maiden flight, will be used in China’s projects of manned space station, third phase of lunar exploration and Mars exploration.
