The Comona Islands are an island chain located off the southeastern coast of the Usean continent. The islands feature a tropical climate and are home to the Riass Space Center, Comona University and a military airport. The islands have been the setting of several major battles.


20th Century

In December 1994, the International Astronomical Union discovered the existence of an asteroid that had a likelihood of entering Earth's atmosphere. The IAU formed a special team of astronomers, who named the asteroid Ulysses 1994XF04. Comona University, believed to be located on the Comona Islands, worked along with Shellsbridge University to calculate the asteroid's trajectory, and by October 1995, confirmed that it would impact the planet.[3]

This information wasn't made public until April 1996; until then, it was privately shared between allies of the FCU, who formulated plans to deal with the threat of Ulysses.[3] One proposal involved an anti-asteroid laser system, which could be equipped to satellites, and used to destroy Ulysses from space at long range. Although the laser system was never fully completed, it did possess functional attack capabilities against surface targets on the planet. It remained in storage at the Comona Islands for some time.[2]

Usean Continental War

The Comona Islands and the Riass Space Center were captured by Usean Rebel Forces.

On August 30, 1998, the Usean Rebels commandeered all of the anti-asteroid laser units and planned to launch a satellite equipped with one to destroy the Usean Allied Forces. The Allied Forces launched a successful attack on the space center and destroyed all of the laser units, including the shuttle that was preparing to launch. Scarface Squadron was then alerted that Beast Squadron, who survived their first encounter with Scarface, had entered the airspace. After an extended dogfight over the islands, Scarface Squadron emerged victorious, leading to the ultimate success of Operation Alphaville.[2]

21st Century

At some point in the early 2000s, the Comona Islands joined the Independent State Allied Forces. At the outbreak of the Second Usean Continental War, Erusea invaded the entire Usean mainland but never took control of Comona.[4]

Second Usean Continental War

Following Erusea's use of Stonehenge against ISAF forces during Operation Blackout[5], ISAF organized a reconnaissance satellite launch from Comona—codenamed Operation Countdown—in preparation for a mainland offensive. Erusea learned of ISAF's intentions and deployed a large aerial force to prevent the launch. ISAF responded in kind, and a major air battle broke out over the space center. At some point, a formation of Erusian B-2A Spirit bombers entered the airspace. Mobius 1 broke off from the furball and downed the approaching bombers. The launch proceeded as planned and the satellite was unharmed.[6]

Usean Corporate War

Over the next three decades, the Comona Islands would continue to host major space operations. At some point, they came under the ownership of Neucom Incorporated. During one of the seminal events in the Nemo Project, an R-352 Sepia was launched to destroy General Resource Limited's Orbital Satellite Laser units in the upper atmosphere. Depending on Nemo's actions up to that point in the story, Nemo either pilots the R-352[7] or prevents its launch.[8]



  • The Comona Islands closely resemble the Florida Keys in appearance as well as hosting a military airport. However, Florida's space missions are primarily launched from Kennedy Space Center, whereas the Comona Islands consist of an airbase and various space facilities in one place.
  • The Comona Islands appeared as the West Indies Comona Base for various missions in Ace Combat Infinity. Both facilities host a space center; however, Comona Base can also perform SSTO launches—the Comona Islands' space center cannot.
