SI Orbital Defense Platform

The SI Orbital Defense Platform were part of Spire Industries Space Division and was built in Kobol's orbit in order to defend the planet from insurrectionists attack. Though, there were already orbital defense stations onboard, but this is was to increase the profit of the Industries and to support firepower from it's neighboring defenses. This was presumed to be one of the weakest orbital defense platforms built but was able to help larger defense platforms of the UNSC to destroy Covenant vessels or small flying units on the area. All of this were destroyed after Kobol was lost.
