First of all there is no Anka 4 in any public SSB document that I know of.
The only time Anka 4 was mentioned was few years ago when Anka 3 was being shown and Temel Kotil mentioned the name. He said “
we are going to have a supersonic version of Anka 3 , we will have Anka 4.”
We know that Anka3 is a flying wing and it is not technically feasible to produce a supersonic flying wing.
But looking at the below picture, one can see that this plane with vertical rudders can be supersonic. But we don’t know if it is the Anka 4.

Baykar’s KE is a private concern’s investment to produce a UCAV that they can make some money on. Looking at it, one can see that it is not at the same level of engineering as what Tusas can produce. But it will serve a purpose and be just as effective. Also in all honesty, as far as UCAVs go they seem to be a step ahead. But a Tusas that manufactured supersonic flying jets like Hurjet and KAAN, is bound to become better at anything that Baykar can make. But will it be the right choice to use Tusas’s resources on simpler platforms?
Tusas is a state owned entity as per
@TR_123456 ’s above post. Their brief is to produce for Turkish armed forces the newest and best technological marvels they can muster. So it is their duty to produce a platform that will outperform, if need be, a Kizilelma too.
