A spokesperson for Russia's defence ministry has said that Moscow has destroyed an underground depot in western Ukraine using hypersonic missiles.
Igor Konashenkov claimed that the warehouse had been housing missiles and "aviation ammunition of Ukrainian troops".
Russia has never before admitted to using hypersonic missiles in combat.
They are cutting edge ballistic missiles that can fly in the upper atmosphere at more than five times the speed of sound.
According to the Russian military, the "Kinzhal" missile system used in the strike is capable of hitting targets at a range of more than 2,000km (1,242 miles) and can overcome all existing air and missile defence systems.

But what type of weapon are they? 什么是超音速导弹？
Hypersonic missiles can fly in the upper atmosphere at more than five times the speed of sound They are considered more manoeuvrable than conventional missiles and are more capable of avoiding interception from air defence Russia's defence ministry said the missile used to target the arms depot in Ukraine was capable of reaching targets at a range of more than 2,000km (1,242 miles) Last year, Russia said it had successfully test-fired a hypersonic missile from a frigate in the White Sea off its north-western coast It said it aimed to include the weapon when arming Russian cruisers and submarines Along with Russia, China, the US, and at least five other countries are working on hypersonicmissile technology
Hypersonic weapons are highly manoeuvrable weapons that can travel at sustained speeds of more than Mach 5. They are divided into two categories: hypersonic glide vehicles (HGVs) and hypersonic cruise missiles (HCMs). HGVs (also referred to as ‘boost-glide vehicles’) are non-propelled missiles that glide towards their target at hypersonic speeds after being launched by a rocket into the uppermost layers of the atmosphere. HCMs, too, use traditional booster rockets to bring the projectile up to supersonic speed but then switch to a scramjet propulsion system that enables the missile to sustain hypersonic speed.
Missiles flying at ultra-high speeds are not particularly new. Ballistic missiles, for example, may reach up to Mach 25 upon re-entry.[1] The difference, however, is that ballistic missiles follow a more or less predictable flight path. In the event of an enemy ballistic missile launch, missile defence systems can estimate where the missile will re-enter and adapt accordingly. The novelty of hypersonic missiles is in their manoeuvrability. This allows them to follow far more erratic flight paths, rendering the logic behind contemporary missile defence systems obsolete.
俄国防部发言人声称俄军使用超音速导弹摧毁了乌西一个地下仓库。如果证实，这将是战争史上首次使用超音速导弹。
乌克兰和西方还没证实。

普京发动侵略战争是非正义的，必败。
第一次海湾战争标志着传统战争的终结，非洲部族之间的棍棒战争除外
毛主席的话，一句顶一万句！
并将再次在乌克兰得到验证！
毛语录是百病包治的万金油、总能捡出一句适用滴
导弹速度越高， 就越不可能 “more manoeuvrable”， 这是常识。
超高速导弹不易拦截是以为速度太快而不是会躲避拦截。 事实上导弹设计根本没有考虑 manoeuvrability。
蒙古那会还没有什么正义不正义，纯属两个人群互相打架，就和两群狼抢领地一样。

只用常规武器，付出较大伤亡代价和较长时间消灭乌东乌克兰主力，之后逼乌谈判。如果乌坚持不谈就扶植乌东另立政府搞代理人战争，提供武器让乌东俄裔和乌裔长期打下去。
