After the sucessful testing results of the R-808 Phoca shuttle, Neucom has decided to implement weapons on spacecraft for combat purposes. Soon afterwards, they discover a group of General Resource satellites in orbit, seeing the moment as an occasion to test their new technologies.
General Resource soon discovers the plan and carries out an attack on the Comona Islands to prevent the launch. Piloting the new R-352 Sepia, Nemo launches from a rocket silo and mans the ship through the Earth's atmosphere, seeking out and destroying four Orbital Satellite Laser weapons scattered across space.
- The events of the mission are some of the only in Ace Combat 3: Electrosphere to be depicted from two different perspectives. In the General Resource arc mission "Technology Transer", Nemo is instead part of the GR force trying to prevent the R-352's launch.
- If the four-minute time limit runs out, the player will be treated to a special scene where Nemo is destroyed by an OSL satellite.
- This is one of the few missions where the use of the Orbital Satellite Laser as a weapon is prohibited.
