During last night's large-scale Russian missile attack on Ukraine, the interception rate of Kh-101 cruise missiles was unusually low - one of the lowest so far this year.

Out of roughly 48 Kh-101 cruise missiles launched, I could only confirm around 10 interceptions, mainly by fighter jets.

In my opinion, this was caused by Ukraine's ongoing F-16 maintenance crisis, and due to the fact that Russia is striking areas of Ukraine closer to the border, providing Ukrainian air defences with much less time to shoot down the missiles. The missiles also flew in very large groups immediately towards their targets, without changing course much, completely overwhelming Ukrainian air defences.

The Kh-101s impacted three cities - Kremenchuk (Poltava Oblast), Pryluky (Chernihiv Oblast), and Oleksandriya (Kirovohrad Oblast).

Most of the impacts occurred in Kremenchuk, while around a dozen occurred in Oleksandriya, along with another dozen or so in Pryluky. Multiple different locations in Kremenchuk, including the hydroelectric power plant, were hit.

The interception rate on Kalibrs was much higher (roughly 9 out of 12 missiles were shot down), with the remaining 3 striking two different targets in Kremenchuk.

As for ballistics, patriot systems in Kyiv shot down ~4 out of 10 Iskander-M/RM-48U S-400 missiles, and air defences near the city of Ukrainka in Kyiv Oblast shot down both Oniks-M supersonic cruise missiles targeting the Trypillya Thermal Power Plant. The 2 Zircons both impacted Trypillya TPP.
