Confirmed hits by Ukrainian drones so far:
5 Tu-95MS strategic bombers, 4 at Olenya and 1 at Belaya (not 6 like previously said)
2 Tu-22M3 strategic bombers, both at Belaya
1 An-12 cargo plane at Olenya.

There are unconfirmed reports of 2 Tu-160s being hit too, and there is footage of at least 2 more fires burning at Belaya Airbase, however the source of these fires has not been determined. Then there's the explosions reported at Diaghilev and Ivanovo Severny Airbases.

This confirmed number is almost certainly going to increase further.
