Then order the Hyperions and the fighters to Attack All Surface Elements as a group.
I noticed the Hyperions hadn't properly activated Shoot to Disable behaviours so ordered them as a specific group. Shoot to Disable activated and they closed to range but are either trying to fire missiles but overidden because it is a station or for some other reason are not in Main Battery range. I'm not sure if this behaviour triggers if they are not given engagement orders with the fighters first and will test that shortly.
M turrets can fire Heavy Missiles I think but automatic resupply always downgrades them to Light ones, and it would be nice to be allowed to use missiles against stations, but that may be intended and not a bug.

Here's your save.
