 Russians fire superweapon AS-24 Killjoy ballistic missile at Ukraine airfield. Vladimir Putin's military has fired his superweapon AS-24 Killjoy ballistic missile at an airfield in central Ukraine, British Defence Chiefs said, according to The Standard. They believe it is the first use of this missile system for six months. In its latest intelligence update, the Ministry of Defence in London said, on 14 December The Russian Air Force highly likely carried out the first use of an AS-24 Killjoy air-launched ballistic missile since August 2023. Russia launched at least one missile into central Ukraine, likely targeting a military airfield. The briefing added, one of the six superweapons President Putin announced in 2018, Killjoy has been earmarked to play a major role in Russia's future military doctrine. In the Ukraine war, Russia has reserved the weapon for what it perceives as high-value, well-defended targets. Killjoy has almost certainly had a mixed combat debut. Many of its launches have likely missed their intended targets, while Ukraine has also succeeded in intercepting attacks by this supposedly undefeatable system.
