I'm really confused on what you're asking.

The medal for S-ranking all missions on Normal difficulty appears after you complete the final mission with an S rank on Normal difficulty. By final mission, I mean the last mission without an S rank that you get an S rank. For example, in Ace Combat 5, if you have all missions except Mission 12 S-ranked, then you'll get the medal once you earn an S rank on Mission 12.
