by the way if the st21 really put into reality, then it's IRST should be something even stronger than that of f14d's, and the AESE radar is even more monsteriosly powerful than f22(you got what i mean?)
the cockpit would be like a more spacious f18d bock50, with less nob and button like removed manual switch of stab aug( full fly by wire), a f18 alike HUD, MFD, fully removed anaolg gauges and a similar stick as f18 with dlc for pilot, for RIO, it would like later version f14d( more removed system) it also would take it could also take f119 as a alternative option( cost efficiency?), which is guarantee to be strickly classified, i could say within 10 years, majory detail of those information is still unaccessble, just simply imagination?
