Before it, the biggest solid-fuel civilian rocket in China

was the Long March 11, with a length of 20.8 m, a diameter of 2 m and a liftoff weight of 58 tons.

Information previously published by CASIC said the rocket that will fly first is to carry six satellites.

While preparation for the Kuaizhou 11 mission is underway, designers at the Wuhan academy have begun to develop two n

ew solid-propellant rockets of bigger size and carrying capacity-Kuaizhou 16 and 21-said Hu, the rocket designer.

The Kuaizhou 16 will have a diameter of 3.5 meters and be able to place a 4-ton payload in low-Ear

th orbit. The Kuaizhou 21 will be bigger-with a diameter of 4.5 meters-and will also be mightier, able to se

nd a 20-ton spacecraft to low-Earth orbit, power similar to the United States’ Falcon 9 Full Thrust, Hu said.
