Russia's long-range heavy bombers have not launched cruise missile strikes against Ukraine for more than a month. This is the longest break in the operation of Russian long-range aviation since the beginning of the conflict. This is stated in a report by the UK Ministry of Defense.

Russia can still use other strike capabilities, but long-range aviation has been the main method for delivering precision strikes from a remote position.

"Russia almost certainly needed to reduce the frequency of its strikes to replenish its stockpile of cruise missiles. It is likely that Russia will use any newly produced munitions to strike Ukraine's energy infrastructure in the winter," the report said.

According to British intelligence, Russia is likely to continue attacks with drones developed by Iran.
