Do you like teapots? Fine, let us talk about the teapot currently orbiting the sun on the opposite side, so small, we cannot see it, but it is obviously there, ancient books and the elder says so. You do not believe me? Then where is your evidence for its not-existence? You cannot prove it? See: The teapot exist!
If it exists, it doesn't follow, that it is used for a tea, or in this case, that it has any military value over military satellites on the Earths orbit... even if it can disable sattelite, that doesn't follow that it is the best satellite disabler and that teapots function is exlusivelly to disable a satellite.
Sometimes stairs are just used as a stairs and there are no other functions for them, than just walk those steps up and down, up and down - every day.
