With all this said, please remember the specification for T-X was for avionics that emulate modern frontline capability. That does not mean it will, or could, ever have an actual Radar.
Same could be said for the M-346, before the Israelis decided to put a radar in their 'trainer' aircraft and use them operationally. Also, as the Jane's story states, the plumbing and cooling for such operational equipment is already in place in the T-X.
