I think they currently have 19 (did have 20). No confirmation of any other aircraft being destroyed just rumours. There is a commitment to provide a total of 72, giving the UAF 4 complete sqns of 18 aircraft per sqn.How many do they still have left that were handed to them?
They've had one shot down or malfunction and another 4 destroyed at an airbase in western Ukraine by Russian missiles.
These will be released in tranches along with groups of trained pilots, ground crews and equipment.
