The analysis for the overall theoretical debris survivabilty of mega-constellation architectures, with an emphasis on space-based ballistic missile defense constellation (SB-BMD), is explored via three extensive different Monte Carlo simulations: preliminary analysis of low Earth Orbit (LEO) mega-constellation survivabilty following a fragmentation event within the constellation, analysis of LEO mega-constellation survivability with a fragmentation event occurring on a satellite performing a maneuver to insert itself within the constellation, and the analysis of LEO mega-constellation survivabilty after a fragmentation event resulting from the destruction of a missile. The LEO mega-constellations represent the SB-BMD constellation. The first two analysis sections will include simulations on the LEO constellation and a medium Earth orbit (MEO) constellation, in order for comparison of survivability. Each simulation will build on itself and provide insight in how a mega-constellation interacts with varying types of debris events, with the end goal of establishing tactics for the SB-BMD. An operational range of the SB-BMD will be developed, to ensure that the constellation engages the missiles at window of altitudes to minimize the overall threat of the resulting debris field on the SB-BMD mega-constellation.
