The fuel tank the base currently uses to transport fuel to the Black Rabbit Space Station is actually not much different from the rocket body—in appearance, they are even identical.
It is launched using the New Yuan No. 3, using a 7-meter diameter design, only with a few more small engines for attitude adjustment compared to a normal rocket's second stage.
However, its production cost really isn't low, the liquid hydrogen container is inherently expensive. Being able to carry nearly 120 tons of fuel, the cost for a single resupply mission is about 500 million RMB, including the rocket launch costs of more than 300 million RMB. Yet, there's no room for further cost reduction.
Within United Mining's procurement price, the quote is 1.2 billion RMB. On the surface, it would take 12 billion RMB for just 10 launches, and even United Mining's funds can't withstand such expenditure.
