Unlike the other first spacecraft of New Yuan, "Enterprise" was directly purchased by the military for an extravagant sum, becoming an active space shuttle in the Space Force.
For Earth's near-Earth transportation, "Enterprise" had limited significance. The Moon was sufficiently serviced by Chapter 9, and the biggest prospective application of Enterprise would still be to follow "March" on exploratory ventures.
At that time, "March" had only completed its design goals. The subsystems and overall performance still needed testing, and significant modifications and trials were required for deep space missions. There was no urgent mission requirement in the short term.
Another point was that Enterprise had as many as six nuclear reactors. Although power generation was a secondary function, they could also provide an unimaginable abundance of electricity for a platform of this size.
