Putin's feared Zircon in mass production stage; Key element of hypersonic triad

Zircon hypersonic cruise missile being mass produced. Hypersonic weapons travel 5 times faster than the speed of sound (beyond Mach 5). Conventional weapons have predictable paths; Hypersonics maneuver more in flight. Hypersonics rob adversaries of reaction time and traditional defeat mechanisms. The Kinzhal is the air-launched hypersonic missile, dubbed the 'ideal weapon' by Putin. The other element of the triad is the Avangard, a boost-glide hypersonic missile.
