The fact that Ukraine had 36 Bayraktars TB2, as well as a new batch of these Turkish drones, was confirmed by Reuters and CNN.
Oryx reports 34 (18+16) but let's not split hairs and assume they did have 36.
How come Russia claims to have destroyed 40+ by now? And they're still flying.
Perhaps because mini-Bayraktars, not only TB2, also got into the statistics.
No, they clearly stated TB2:
В течение дня, доложил генерал-майор, российские военные уничтожили еще 65 украинских военных объектов, а также сбили три беспилотника, в том числе Bayraktar ТВ2 турецкого производства.
This was well after the "35" had been "destroyed", and there are few more announcements like that.
