Expert performed high energy laser (HEL) weapon effects analysis and testing for the purpose of determining spacecraft materials and subsystems vulnerability and hardness to continuous wave and pulsed HEL threats. Scope of this test effort included planning, test implementation, results evaluation for critical optical, structural and thermal protection components and materials. Expert was involved in the development of minimum-weight HEL shield concepts and hardened sensor concepts for advanced military space applications, including the Space-Based Interceptor (SBI), Brilliant Pebbles (BP), and Military Orbiter. He is able to perform HEL threat analyses, such as ground-to-ground/air/space, air-to-ground/air/space, and space-to-ground/air/space.

optical warfare





Expert and his colleagues have conducted innovative studies (trades) of active and passive infrared countermeasure applications to space-based weapon platform survivability. The typical countermeasure suite consists of a mix of IR and RF penaids, including decoys, chaff, and platform anti-simulation of varying fidelity/performance capability as dictated by minimum weight and cost constraints. Expert maintains capability to perform IR and RF countermeasure requirements trades and evaluations.

Expert was project engineer for a tactical missile system survivability program with responsiblity for: survivability/vulnerability (S/V) program plan development and implementation; blast hardness requirements analysis and trades for hard missile launcher and control center structures; armor piercing threat resistant silo closure and personnel access door concepts; and blast hardened intra-site cable requirements analysis. He is capable of performing preliminary blast hardened facility and structure requirements analysis and trades for both conventional and nuclear warhead threats.

Expert has experience studying and analyzing the effects resulting from explosions of tactical and strategic nuclear warheads, as well as conventional high explosive and chemical explosive warheads. Effects examined include air blast, ground shock, thermal, nuclear radiation, EMP; and chemical contamination.

explosion effect

Expert has experience studying and analyzing the output characteristics of warheads, including tactical and strategic nuclear warheads, conventional high explosive warheads, and chemical explosive warheads.


Expert was responsible for the development of innovative analyses and trade study models of space platform active self-defense (shootback) using miniature rocket launched hit-to-kill (kinetic) interceptor weapons. These trades yield threat and orbit unique defensive weapon inventory requirements in terms of numbers of interceptors, axial velocity, and rate of fire. He maintains capability to perform space platform self-defense trades.
