- "The hero of Ace Combat: The Belkan War, Cipher's Aircraft. This aircraft's armour has been lightened to facilitate greater fire power. Fully customized preemptive striking capabilities place this fighter at the forefront of any battle. As the leader of the Republic of Ustio's Mercenary Galm Unit, Cipher's overwhelming fighting skills amidst the escalating conflict quickly earned him the moniker, "The Demon of the Round Table". Both feared and respected, his was the path of a true ace."

The F-15E -CIPHER- is a downloadable aircraft in Ace Combat 6: Fires of Liberation. It was released in December 20, 2007 with Pack #03, costing $2.49 (200 MSP, pre-MSP retirement).
The first aircraft in a series of aircraft themed after Ace Combat Zero: The Belkan War, the F-15E -CIPHER- is a homage to the F-15C Eagle used by Cipher, the leader of the Galm Team and protagonist of said game. In appearance, the aircraft resembles the basic F-15C paint scheme in most games, with the sole exception of the blue-colored wings and stabilizers. The number "032" is printed beneath the cockpit area.
The aircraft's air-to-air capabilites have been greatly upgraded, while mobility is given a minor boost. However, as is the case with all other "protagonist"-type aircraft, defense has taken a major blow, meaning that effective use of the Strike Eagle's maneuverability and speed is required for maximum effectivity. Also, the aircraft is notable for having an upgrade to its machine gun, increasing its rate of fire.
