Strategic Orbital Linear Gun

The Strategic Orbital Linear Gun (戦略衛星軌道砲), often shortened to SOLG, was an orbital weapons platform developed by the Osean Federation. It was designed for use with Kinetic Energy Weapon shells, though any ballistic shell could be loaded onto it.

The SOLG was initially developed to counter Yuktobania during the Cold War. When the Belkan War broke out, Osea prioritized the SOLG's development for use in the war, but it was abandoned after Belka's surrender. The Grey Men later completed the SOLG and equipped it with a V2 warhead during the Circum-Pacific War. It was subsequently destroyed by the Razgriz Squadron.

In When the Cold Breeze Blows Away, it would be used by the Islamic State of Iraq and Syria and the Grey Men to target on Canopolis and other cities
