Russia’s hypersonic missiles: Can the world avert an arms race?

Moscow takes a lead in new technology that can evade conventional defences and fly at seven times the speed of sound.

Russian President Vladimir Putin dubbed the hypersonic missile the “invincible” and a few weeks later inspected a prototype lightweight stealth fighter plane.

The only plane comparable to Checkmate, as it is known, is the US-built F-35, and it costs a quarter of the price, opening up new markets.

Dmitry Stefanovich, a research fellow at the Institute of World Economy and International Relations, explains how decades of investment is paying off.
