Space for next slide (has the missiles, and the third slide is the missiles in the OBP) The OBP is a large satellite / small space station that fires powerful missiles. It carries 4 SGM-21 Space to Ground missiles. It can only carry those 4 due to how big they are, and to be replaced they must be brought up into orbit and fitted into the silos. The SGM-21 is a large thermobaric 2 stage missile. The first stage boosts the missile for a very short period of time after re-entry, then detaches and the glide vehicle with a thermobaric warhead will glide and hit the target. Cost Orbital Bombardment Platform - 500 Million SGC SGM-21 - 1 Million SGC
