“He noted that the cost per KF-X jet is estimated at $55 million and its production aircraft is expected to be deployed from 2020.”
This statement seems wildly optimistic. South Korea does not have an indigenous fighter much less a stealth fighter. Unless they are stealing a design and production methods, I do not see how they can deploy a new stealth fighter until 2030.
They need another “partner” to defend their sorry asses too.
