"You're not gonna believe this, Jean-Louis! All of them have ribbon insignias!"
Gene commenting on Mobius Squadron[1]

Mobius Squadron, officially the 118th Tactical Fighter Wing, was an elite squadron comprised of pilots from the Independent State Allied Forces's Air Force. The squadron saw active service during the 2003–2005 Continental War. Its ace pilot, Mobius 1, rose to prominence and became the flight leader of the squadron around the start of the ISAF's counteroffensive in late 2004.

Mobius Squadron was later reformed under the IUN. In 2014, the squadron was deployed against a resurgent Free Erusea.[2]


Continental War (2003–2005)[]

Around the time of ISAF's evacuation from the Usean mainland, Mobius 1 was the sole member of Mobius Squadron; whether this was by design or the result of losing squadmates during the Eruseans' initial offensive remains unknown.[3]

Beginning with the ISAF's Operation Umbrella in September 2004, Mobius 1 quickly established himself as an ace, downing six Erusean Tu-95 Bear bombers and their escort fighters over Newfield Island.[4] Over the course of the war, Mobius 1's accomplishments would inspire confidence in his allies and fear in his enemies.[3]

The full Mobius Squadron—under Mobius 1's command—was later formed by merging several other ISAF squadrons. On September 26, 2005, one week after the official armistice, ISAF dispatched the newly assembled Mobius Squadron to the Twinkle Islands to destroy Megalith, an Erusean superweapon capable of shooting down orbiting asteroid fragments. Mobius Squadron engaged and shot down the Eruseans’ Megalith defense squadron before moving on to the rocket-launch facility. Through the combined efforts of Mobius Squadron and the special forces unit, ISAF was victorious once again, and Megalith was destroyed.[1]

2006 Free Erusea uprising[]

In 2006, Mobius Squadron would return to active service when Free Erusea terrorists mounted an armed insurrection against the postwar Erusean government. ISAF initiated an investigation into the extent of Mobius 1's abilities, which reached the astonishing conclusion that the combat effectiveness of Mobius 1 was equal to that of an entire ISAF squadron. As such, Mobius 1 was scrambled, along with AWACS SkyEye, to suppress the rebellion and restore stability to Erusea as part of ISAF's Operation Katina.[5]

2014 Free Erusea uprising[]

At some point following Operation Katina, Mobius Squadron was reformed into the IUN. The squadron once again saw action against Free Erusea as part of the IUN's peacekeeping forces.[2]

Mobius 1[]

Mobius 1 was an ISAF ace and the flight leader of Mobius Squadron. He was arguably one of the best ace pilots in Strangereal. Mobius 1's heroics almost single-handedly won the war for ISAF, and he is estimated to have the combat capabilities of an entire squadron.[5] He was the only confirmed member of Mobius Squadron until the assault on Megalith.[3]

AWACS SkyEye[]

AWACS SkyEye was the ISAF electronic support aircraft that worked with Mobius Squadron since its first mission over Newfield Island.[3] As an AWACS, SkyEye provided vital tactical and data analysis for ISAF aircraft during combat operations. In 2006, he and Mobius 1 were dispatched to quell the Free Erusea uprising.[5] Since then, AWACS SkyEye has continued providing ECM and radar support for ISAF operations.



  • Mobius 1 and Mobius Squadron derive their callsign from the Möbius strip, a unique geometrical shape that does not exist in nature and can only exist as a man-made thing. The unique combat record and accomplishments attributed to Mobius 1, likewise, cannot exist in nature; this lends the fitting impression that Mobius 1's prowess is beyond the natural abilities of even the best pilots in the world.
    • A Möbius strip is characterized as being a looped ribbon arranged in such a way that it has no beginning, end, "inside", or "outside".
    • Throughout Ace Combat 04, Mobius 1 is commonly referred to as the "Ribbon Fighter" and to a lesser extent, "The Grim Reaper" or "The Ribbon" by the Eruseans.[3]
  • The emblem of Mobius 1 can be unlocked in Ace Combat: Joint Assault by finishing 100 missions.
  • Mobius 1 appears as an enemy ace in the "Ace of Aces" mission from Ace Combat 6: Fires of Liberation.
  • In Mission 14B of Ace Combat Zero: The Belkan War, the Belkan ace Jakob Pfeiffer, callsign "Adler", pilots an F-22A with the same livery as Mobius Squadron.
  • According to radio quotes extracted from the game, there are more than 13 Mobius Squadron members in Mission 18, ranging from Mobius 14 to 20.
  • All Mobius aircraft have the tail code "NP" to signify where the squadron is based. It is implied to mean "North Point".
