Hapa mandharinyuma kidogo kuhusu silaha za babu Putin, leo: Roketi ya Zirkon, inayokimbia kwa Mach 9, lakini ina matatizo kulenga vema kama lengo halisubiri:
Maana si rahisi kupambana na kanuni za fizikia.
Soma kwa undani:
Russia's new Zircon missile can fly at hypersonic speeds or hit a moving ship, but it can't do both.

Putin's 'invincible' missile has a very common problem
- Putin has touted Russian hypersonic weapons like the Zircon missile as impossible to defend against.
- Zircon in particular is powerful but there are limits on what it can do, a Western expert says.
- Like other high-speed weapons, the Zircon's velocity may come at the expense of its accuracy.
Russia's Zircon hypersonic missile can do two things: fly at almost 7,000 mph, which makes it very hard to shoot down, or hit a moving ship. But it can't do both.
Putin's rhetoric can't change the laws of physics. The problem is that objects traveling at hypersonic speeds — Mach 5 and beyond — ionize the air around them, creating a sheath of plasma around the object that blocks radar signals.
Yet radar is precisely how many guided missiles home in on their targets. Once the missile arrives near a designated point, an active radar seeker in the nose switches on, scans the area, and locks on target.
