Russia's 'Undefeatable' Missile Fails in Ukraine, Says UK

The AS-24 KILLJOY missile, touted as a 'super weapon' by Putin, has been missing targets and intercepted by Ukraine's defense system.

Russia's 'undefeatable' AS-24 KILLJOY air-launched ballistic missile has been missing its targets in Ukraine, according to British defense officials.
The missile, which can carry a nuclear payload and can travel faster than the HIMARS (High Mobility Artillery Rocket System) that the U.S. has given Ukraine, was likely fired at a military airfield in central Ukraine on December 14.
This was probably the first time since August that Russia had fired the missiles, which are one of the six 'super weapons' announced by Putin in 2018 as playing a significant role for Russia's military doctrine.
Many of the missile's launches have likely missed their intended targets, while Ukraine has also succeeded in intercepting attacks by this supposedly 'undefeatable' system.
Ukraine had already shot down six Kinzhal missiles that Russia fired in an assault in May.
