A common feature in the Ace Combat series, clear rank gives the player a certain letter grade after a mission's completion to evaluate their performance. The feature was first introduced in Ace Combat 3: Electrosphere and has been utilized in almost every Ace Combat game since.


The player is assigned their clear rank at the end of a mission, typically during the debriefing. Different games have different clear ranks available to the player. Typically, the lowest clear rank is C, followed by B, then A, and finally S. The player is sometimes rewarded with bonus points depending on their clear rank.

In some games, medals or aircraft are unlocked by completing all missions with an S Rank.
