F-15 is the name used to distinguish the variants of the Eagle series (but only the ones seen in Ace Combat, not real variants like the Singapore-employed F-15SG).

• F-15C Eagle, the original model

• F-15E Strike Eagle, two-seater attack variant, multirole in AC6

• F-15S/MTD (Short/Maneuvering Take-off Demonstrator), advanced variant of the original Eagle

• F-15S/MT Eagle+, COFFIN-equipped, high-tech variant of the S/MTD, employed during the the Corporate War of 2045
