Russia Claims to Have Developed Special Fuel for Hypersonic Missiles

Russia has created a powerful recipe for fuel that will allow missiles to fly faster than five times the speed of sound, a development that if utilized effectively would make Russia a major player in a growing hypersonic arms race, a deputy defense minister said.

“The recipe has been created and the energy accumulated in this fuel will enable our vehicles to exceed Mach 5,” General Dmitry Bulgakov, deputy defense minister, was quoted by the TASS news agency as saying on Tuesday.

Mach 5, or 6,126 kilometers per hour, is considered to be the barrier between supersonic speeds and hypersonic speeds.

Militaries around the world are racing to harness the power of hypersonic flight, which by slashing missile flight times will complicate countries' ability to detect and respond to attacks and potentially upset the global military balance of power.

The United States, China, Russia and India are all working to develop hypersonic missile systems, but the engineering challenges are daunting. Hypersonic missiles need to be strong to withstand the stress of flight beyond Mach 5.

There is some inaccuracy in the article later.  Yes, the boost glide work is being done by the US and China.  However, the US has been working on scramjects, which are definitely not boost glide technologies for hypersonic cruise missiles, too.
