I think UK would be pleased to sell its 30 x Tranche 1 Typhoons. They are scheduled for withdrawal from service in 2025. Spain and Italy might be interested is disposing of early Typhoons, too. I don't know what control Eurofighter partner governments have over other partners selling their used Typhoons. I think that the UK ones have a lot of hours left on the airframes. UK paid around $60 million for its Tranche 1 Typhoons, so they could be very cheap. Spares are reported to be very expensive, but using them for 5-10 years as a stop gap to KAAN might be economically practical for Turkiye.
