In support of the Navy Standard Missile Lightweight ExoAtmospheric Projectile (LEAP) program GDC designed, manufactured, integrated, and delivered a unique air bearing test bed that allowed the fully integrated flight hot-gas guidance and control missile section to be inserted through a circumfrential air bearing. The pre-flight test program consisted of cold-gas tests in the laboratory to functionally check-out the flight software, followed by a full-up hot gas test conducted at altitude in a large spherical vacuum chamber. GDC also provided a center of gravity balancing system, that maintained the test item balance during expenditure of the hot gas generators.
