===Reserve assets===
While the UNSC would establish and maintain massive stocks of decommissioned spacecraft in years to come, in March 2170 there were no such facilities or plans for creating a reserve fleet. Due to the endless demand for military spacecraft during the Interplanetary War, the UNSC kept all available ships in service as long as possible. The first UNSC ships to enter reserve did so in the months after the conclusion of the fighting.
