C-level Base, which essentially served as a support to the B-level Base, had a new task: to produce an unmanned cargo version of the deeply modified H1W.
Compared to the H1, the H1W had an upturned nose because it was designed to be launched in conjunction with the An-1250 and shuttle-shaped fuel tank. Although its cargo bay was somewhat irregular, it could still accommodate large satellites.
While incorporating some new technologies, the production cost of the H1W was significantly reduced due to the lower operational requirements of unmanned craft, which allowed for fast production. It rolled off the assembly line in November and was completely ready for its maiden flight in December.
The fuel tank was also simple—a disposable pressure vessel—, with the only expensive part being the insulation material covering its surface, as the extremely low temperatures of liquid hydrogen and oxygen could not be allowed to spread unchecked.
