GAO also lists the challenges of developing a hypersonic weapon, and are likely some of the reasons why the U.S. is losing the weapons race against Russia and China. Heat-tolerant materials: At hypersonic speeds, the exterior temperature of a hypersonic vehicle or weapon can exceed 2,000°F, necessitating advanced materials that will protect interior electronics. Such materials also need to be mechanically strong and efficient. Propulsion technology: Refinement of engine technology is needed for HCMs. This includes increasing the reliability and efficiency of scramjet engines. New types of engines that allow for propulsion from standstill to hypersonic speeds are also being developed, which would eliminate the need for rockets to provide the initial launch. Weapon tracking: Defense against a hypersonic weapon would involve tracking and intercepting it, but current radar and satellite systems are inadequate for this task. Limited testing resources: There are limited places to perform ground tests and flight tests of hypersonic weapons and vehicles in the United States. Currently, there are limited wind tunnel facilities in the country capable of running propulsion tests of hypersonic weapons and vehicles. Safety and control: Hypersonic velocities require additional improvements of aircraft control and guidance to help ensure the accuracy of hypersonic weapons.Now it's too late, and I'm DELIGHTED. We are technologically checkmated. For at least a few years we can't even DREAM of attacking Russia or its friends. The world is SAFE for a few years. THANKS, RALPH.
