The Solano was in service with the Free Navy and assigned to the Michio Pa fleet. Under the Free Navy the ship was used to capture colony ships heading towards the Sol gate. It is one of the Four Horseman, along with the Connaught, Serrio Mal, and Panshin, the most experienced of Pa's fleet. When Michio Pa defected from the Free Navy the crew of the Solano joined her. During one of their operations the Solano captured the colony ship Brilliant Iris out of Luna.
Eventually when this faction joined the Consolidated Fleet Offensive the Solano was heavily damaged and stripped for all useful materials to be put on other ships. The ship's epstein drive was kept intact and functional, and during the Battle of Pallas Station the Solano was used as a "Sacrifice ship" that would ram into Pallas's docks leaving them unusable. However during the battle Michio Pa adjusted the plan to instead destroy the station defenses and get the Solano next to the docks to slag anything that came out with it's epstein drive.
