Per Bloomberg, Erdogan will directly mention the Qatari EFs during his visit.
Fatih is right to point out all three countries mentioned(Qatar, Kuwait, Oman) are EF users. Kuwait also have 3As.
Reuters mentions that Turkey is looking at both Qatari and Omani EFs. My brainfreeze, Kuwait, Oman and Qatar all operate 3As, with ECRS MK0 AESA radars. Tranche 3A is the most modern EF flying today, mostly thanks to its AESA radar.
Bloomberg had mentioned 24+16 aircraft. Reuters mentions 12+28. Maybe 6 from Qatar, 6 from Oman; details are scant. Qatar have already ordered 12 T4 aircraft, while no Omani follow up yet exists.
I don't really think cost is the actual reason for seeking second hand aircraft; but timelines. A 3 year old Qatari EF won't be that cheaper; and again, real costs are in setting up the capability and maintaining it, not flyaway cost.
"For the Typhoons, Turkey is nearing a deal with Britain and other European countries in which it would promptly receive 12 of them, albeit used, from previous buyers Qatar and Oman to meet its immediate needs, according to a person familiar with the matter.
Eurofighter consortium members Britain, Germany, Italy and Spain would approve the second-hand sale proposal, in which they would provide Turkey with 28 new jets in coming years pending a final purchase agreement, the person said.
Erdogan is expected to discuss the proposal on visits to Qatar and Oman on Wednesday and Thursday, with jet numbers, pricing, and timelines the main issues.
Erdogan is then expected to host British Prime Minister Keir Starmer and German Chancellor Friedrich Merz later this month, when agreements could be sealed, sources say."
