The SOLG program involved the creation of military combat satellites equipped with kinetic energy weapons. Such weaponry would be able to perform kinetic bombardment from anywhere in the world using various metal rods equipped on the bodies of the satellites; however, for some reason, the project was abandoned and the satellites left in orbit.
During Operation Eternal Liberation, the USEA Federation came in control of the various satellites. The kinetic platforms were out of commission, so they decided to drop the satellites onto Tokyo to cause massive damage to the populace. The United Nations Forces responded by deploying their mercenary forces to destroy the incoming satellites. Thus far, all of the satellites commanded to fall have been destroyed, likely falling into Tokyo Bay and causing no damage to the city.
Three satellite designs were created as part of the SOLG program, from which numerous units were developed.
SOLG -Schroeter-, named after Johann Hieronymus Schröter, is the base unit. Schroeter features various kinetic weapon launchers, as well as its own defensive laser system. These lasers protect the satellite from both enemy attack as well as space debris. However, of the three designs, Schroeter features the least armor and has proven easy to destroy by the UNF.
SOLG -Oort-, named after Jan Oort, is an upgraded version of Schroeter. Oort features all of the weaponry found on the base unit, but its exterior shell was buffed to withstand repeated attacks. As compared to the grey and black colors seen on Schroeter, Oort displays a red trim throughout its design.
SOLG -Lexell-, named after Anders Johan Lexell, is the most upgraded version of the project's satellites. Lexell continues the trend from Oort and retains all of the original weaponry while featuring a further upgraded exterior shell to protect against most damage. Its design displays a gold trim.
