An F-15E launched a hypersonic missile demonstrator, dubbed HyFly, which cleanly separated, then successfully ignited its solid rocket booster, reaching a speed greater than Mach 3, as part of a hypersonics test program run by the Defense Advanced Research Projects Agency and Boeing, states a company news release. The partnership hopes to use the HyFly program to mature the dual combustion ramjet hypersonic missile concept, eventually enabling a missile that is compatible with Air Force platforms as well as Navy aircraft and vessels.
Expanded production of the B-21 bomber can be accomplished at Northrop Grumman's existing Palmdale, Calif., facilities, the Air Force said. It also said test aircraft will be so simular to the production version that early examples could be used in combat if called for.
