Innovative solutions are sought to reduce cost and lead-time of hot gas valve components located in the post boost control system (PBCS) of the U.S. Navy s Trident II D-5 Fleet Ballistic Missile. Current PBCS components are based on Nb, Ta10W and TZM, with protective coatings. Although structurally sufficient and compatible with the oxidizing propellant, disadvantages include density, cost and lead-time. A concept promising to reduce weight, cost and lead-time is comprised of a carbon-based core and thin (i.e.
