I do not think Haluk Bayraktar is referrring to a TF-6000 class engine, or altogether he might be referring to TF-10000 that is planned in future versions of KE but i do also know this is not the first time Baykar is attempting to step into motor business. Last time they did, some "unfortunate events" have occurred.While it may seem redundant to have two jet engine producers/developers, it can also benefit Turkiye through competition i.e. Baykar vs TAI.
Baykar has a ton of money and they need to invest it to increase shareholder value (instead of paying it out to investors as dividends). Fergani Space and now this jet engine venture seems to be good business choices. I am still waiting for Baykar's big push into the civilian domain.
