"X-51 was really a proof of concept test," said Air Force Chief Scientist Mica Endsley. "It showed that you could get a scram jet engine, launch it off an aircraft and it could go hypersonic."

"It was able to go more than Mach 5 until it ran out of fuel. It was a very successful test of an airborne hypersonic weapons system."

The follow-up to the X-51, which has been tentatively planned for completion by 2023, will attempt to consolidate the technology by building a stable air vehicle that can carry guidance systems and other materials while maintaining the same speeds achieved during the test flights."What they are trying to do now is build the whole system so that it is not just about the engine," said Endsley. "You have to have materials that can operate at the kind of temperatures you have when you are going at hypersonic speeds."

"There are a bunch of technological challenges that have to be addressed to make a functioning system that will work."

In theory a hypersonic aircraft could fly from New York to Los Angeles in just 30 minutes however the extreme acceleration would make it impractical for it to carry human pilots or passengers.

As a weapon or spy platform though such a vehicle is likely to prove invaluable.
