**The Russian army raided Kiev on a large scale, and Ukrainian air defense system faced severe tests**
Recently, Russia launched one of the largest air strikes since the war began on Kiev, the capital of Ukraine. 36 missiles intensively bombarded the city and surrounding targets within 3 hours. The Ukrainian military said that the attack included the "Dagger" hypersonic missile and cruise missile. Although it intercepted some incoming targets, infrastructure and civilian buildings were still damaged, causing casualties.

**The battle situation escalates, and the Ukrainian army is trapped in a air defense vacuum? **
Western intelligence shows that the Russian army has recently adjusted its tactics and used the number of missiles and electronic jamming to suppress Ukrainian air defense system. Ukraine has long relied on Western-aided air defense weapons, but the problem of ammunition shortage is becoming increasingly prominent. The attack exposed the defense loopholes of the Ukrainian army in key areas, especially in the face of hypersonic weapons, and the existing air defense network is still insufficient.

**International Response and Follow-up Impact**
NATO announced that it will accelerate the provision of the "Patriot" system to Ukraine, but the deployment will still take time. Analysts believe that Russia's move is intended to weaken Ukraine's rear morale and gain initiative for the eastern battlefield. With the delay of Western military aid, the Ukrainian army may face more severe in the short term.
