According to the Union, an object traveling Mach 5 for a period of time "slowly tears itself apart during the flight." The heat is so great it creates a "plasma" around the craft that makes it difficult "to reference GPS or receive outside course correction commands."
If the target is moving, as with an aircraft carrier or a mobile missile, it will be almost impossible to alter the weapon's flight path to intercept it. And any external radar array would never survive the heat or else be so small that it would have very limited range. In short, you can't get from here to there.
Lockheed Martin says the tests are going just fine, but then Lockheed Martin is the company that builds the F-35, a fifth generation stealth fighter that simply doesn't work. It does, however, cost $1.5 trillion, the most expensive weapons system in US history. The company has apparently dropped the scramjet engine because it tears itself apart, hardly a surprise.
The Russians and Chinese claim success with their hypersonic weapons and have even begun deploying them. But Pierre Sprey, a Pentagon designer associated with the two very successful aircraft -- the F-16 and the A-10 -- told defense analyst Andrew Cockburn that he is suspicious of the tests.
"I very much doubt those test birds would have reached the advertised range had they maneuvered unpredictably," he told Cockburn. "More likely they were forced to fly a straight, predictable path. In which case hypersonics offer no advantage whatsoever over traditional ballistic missiles."
While Russia, China and the US lead the field in the development of hypersonics, Britain, France, India and Japan have joined the race.
Why is everyone building them?
At least the Russians and the Chinese have a rationale. The Russians fear the US anti-missile system might cancel out their ICBMs, so they want a missile that can maneuver. The Chinese would like to keep US aircraft carriers away from their shores. But anti-missile systems can be easily fooled by the use of cheap decoys, and the carriers are vulnerable to much more cost effective conventional weapons. In any case hypersonic missiles can't do what they are advertised to do.
