"This report analyses the future impact that hypersonic weaponery will have on global affairs. Hypersonic systems include anything that travels faster than Mach 5, or five times the speed of sound. We may be on the cusp of seeing hypersonic weapons proliferate around the world, with Russia, China and the US all in the process of developing and testing them. By 2030 they are likely to be in the inventory of all of the major powers. And Australia might well join them - we have some world class researchers and have been active in joint programs with the US for over 20 years. The government has added hypersonic weapons to its defence acquisition plan. It's a topic we should be interested in and better informed about."--Publisher's website
