I think you need to get an S on all the archangel's missions. Try getting on the last mission first though, cuz that's the last mission i got an S on and thats when i got meteor.

Must S rank the final mission of each of the Archangel routes to unlock each set of Meteor units. So S ranking Archangel C.E. 71 route will net you the Freedom and Justice Meteors, and ditto on the C.E. 73 route.
