Once the Leasath's invasion began, Falco One and his squadron were deployed to defend their territory from enemy attacks. He participated in several operations targeting Leasath's strike force across northern Aurelia.
In one particular operation, Falco One was assigned to help an Aurelian fleet retreat from enemy territory. The mission ended catastrophically, as the fleet was ambushed by the heavy command cruiser Gandr, which destroyed the entire fleet using an SWBM. The airship was later shot down by Falco Squadron and the surviving pilots.
In the ending days of the war, Falco One returned to the front lines with his team. Together, they assisted the famed Gryphus Squadron in an ambush mission in the Danern Straits of Leasath's territory.
