Russian sources: The AFU has begun to use light Yak-52 fighters to intercept Russian Orlan-10 reconnaissance aircraft flying in the Odessa region.
The Yak-52 is a Soviet (1974) primary trainer aircraft in use by Russia, Ukraine and several other countries. I am not aware of an armed variant of the aircraft but is is not unfeasible.
