When the defeat of the Celestial Being by the United Nations Forces (UN Forces) seems imminent in AD 2308, the Fereshte team set out to recover equipment Celestial Being had in their secret supply bases to prevent them from falling into the enemy's hands, and to ensure resurrection of the organization. After the UN Forces' victory, Fereshte's Gundam Meister, Fon Spaak instructed the use of the recovered equipment to enhance Fereshte's own Gundams. As a result, the spare parts of the GN-001 Gundam Exia were used by Sherilyn Hyde to upgrade the Gundam Astraea Type F, creating the Gundam Astraea Type F2.

Replacing some of the Astraea Type F's deteriorating parts, which have been in use since the machine started out as the GNY-001 Gundam Astraea 15 years prior, with new parts lead to considerable improvements in the suit's overall performance. Additionally, the hardpoints on the forearms and legs of Astraea Type F are replaced by spare GN Condensers from Exia, and the pair of new head antennae have GN Particle control capabilities like the two clavicle antennae. With its four antennae setup, the Astraea Type F2's ability to control GN Particles is increased by more than 40%.
