The homegrown rocket tank, measuring five meters in diameter and 20-plus meters in length, consists of bottom parts and eight tubular sections, which are welded together, according to the China Academy of Launch Vehicle Technology.
The academy made a major technological breakthrough in the welding of such a massive-sized fuel tank, it said, adding that developing and manufacturing a propellant tank are among the most difficult tasks in building a rocket.
