Russia masters hypersonic fuel: Russia claims to have perfected a fuel that will enable its missiles to fly faster than five times the speed of sound. “The recipe has been created and the energy accumulated in this fuel will enable our vehicles to exceed Mach 5,” Deputy Defence Minister General Dmitry Bulgakov is reported to have said earlier this week. The US, China, Russia and Indiaare all working to develop hypersonic missile systems; while the US and China have been focussing their efforts on so-called boost-glide hypersonic missiles, which work on the principle of launching a rocket that then glides to its target, Russia and India have been working together on a hypersonic cruise missile and have already developed BrahMos, that can travel at speeds of up to Mach 3 or about 3,675 km per hour.
