2 decades hell no. What you remember is the Yıldırım missile. It is the predecessor of Bora/Khan but Bora kept secret for a long time that is true it is not even offered for export in its limited-range Khan version not until permission is given to Roketsan so that Roketsan can market it as Khan.I believe wikipedia is faulty on this one. Yes it was first seen fired in action in 2017. However, I believe they've had it in inventory for at least 2 decades now.
@TheInsider, could you enlighten this topic?
