This article is about an in-universe event. For the in-game mission, see Bird Hunt.

The First Battle of Tokyo was an assault on Tokyo by unknown forces.[1]


After the Midway Incident, Martinez Security and the United States Navy Seventh Fleet attempted to prevent the unknown aircraft from reaching Tokyo.[2] However, the unknown aircraft were able to reach Tokyo. In addition, there were reports of a large aircraft with heavy firepower. As a result, Martinez Security and the Seventh Fleet prepared to defend Tokyo.[1]


Martinez Security and the Seventh Fleet arrived in time to support the defense, but not before the large aircraft, codenamed Spiridus, fired its Balaur railgun at Tokyo Bay. However, Antares One was able to keep the Balaur from firing again by repeatedly attacking the Spiradus's heat vent. After several attacks, the Balaur was eventually disabled entirely and the Spiradus was forced to retreat; after additional fighting, the airspace over Tokyo was soon clear of enemy fighters. [1]


Tokyo was successfully defended, but the Spiradus mysteriously disappeared near the Izu Islands; As a result, Antares One and Rigel Squadron were placed on standby in case another attack occurred.[1] In addition, a terrorist organization calling itself the Valahia claimed responsibility for the attack.
