Air and Missile Defense Environment

SEG has provided threat and systems engineering services and critical path products in support of ACAT 1 programs of the Missile Defense Agency Ballistic Missile Defense System (BMDS), Aegis BMD, Navy Integrated Air and Missile Defense System (IAMD) and the Navy’s Air and Missile Defense Radar (AMDR). SEG’s regular improvement of threat engineering tools and product development processes supported the growing demands of simultaneous Aegis BMD baseline developments that required threat characterizations consistent with Intelligence Community assessments, while meeting Aegis BMD and Common Threat data requirements. SEG products are consistently determined to accurately translate threat definitions into threat models that were used to generate 6 Degree of Freedom (6DoF) trajectory and RF signature data. All data, tools, and simulations satisfied fidelity requirements and design needs for the customer, including Aegis BMD Element Capability Specifications for Aegis BMD 4.0.1, 5.0, 5.0 CU (Capability Upgrade), 5. and 6.x baselines, AEGIS IAMD Baseline 9A and 9C, and the AMDR acquisition program.

In support of the MDA Common Threat effort and Aegis BMD, Navy IAMD, and Navy AMDR acquisition programs, SEG has developed numerous comprehensive ballistic missile threat systems threat engineering packages. The threat package products easily interfaced with the Prime Item Developer’s simulation architectures to minimize integration and design timelines. These threat products consisted of 6DoF Monte Carlo launch-to-impact trajectories for all the principal objects, 3D Scattering Center Models (3DSCMs) and the ASC access tool, DebrisSim Simulation, DebrisSim Inputs, WakeSim, RF-to -Trajectory Frame Correlation Tool, HDFProc Tool (trajectory data postprocessor) and user documentation.
