Space Force may sound like a pointless, and name only branch, but the Space Force will have a few roles to fulfill. First, they control all of the rockets that would fire into space. This will allow the installation of satellites which will provide a number of roles including Global Positioning, spy satellites, and communications channels. This is the biggest role of the Space Force, but an important one at that.
As a humanitarian goal, the Kaldan military will work with other nations in cleaning up the space trash that currently encircles the planet. This is a potential threat of not only the nation, but the world as a whole, and there never seemed to be a means in dealing with expired satellites. With the Space Force, there will be a plan in place for every satellite launched in space by the Kaldan government.
