KAAN needs to start resuming flying tests like Hurjet is doing, in order to develop in to a plane that can become a block 10 aircraft. That is number one issue.
A second issue is the finalisation of license production agreement of f404 and f110 engines between TAI and GE. If we are to produce 11 more prototypes and 20 block 10 planes until 2028, we need over 60 units of f110 engines in the short term. And if we are to have 2 or even 3 squadrons of KAAN With f110s, then we need between 100 to 150 engines before indigenous engines are ready.
We also need at least 90 units of f404 engines for Hurjet to replace the 68 T38 trainers and 12 F5s in the aerobatic team.
It is not viable to buy them, when we can manufacture them at TEI.
As per below news piece video which has Bloomberg as the reference point of news, Türkiye has applied for permission to manufacture the KAAN’s and 40 F16 V70 jets’ engines in house at TEI. According to this video, currently 2 new KAAN prototypes are in the process of being built. There will be a further 10 units of KAAN prototypes to be produced until initial low rate serial production will start.
