I am not referring to the F-16.
Regardless, you seem to have a lot of sources.. maybe you'll find out.
I cannot disclose everything. So till then we definately have no hms (f16 excluded).
Sir, you are correct but if one pushes the aircraft into only tvc controlled flight the whole plane starts to add drag. And kinetic energy is almost always more important then changing nose position.Not exactly, TVC also has a lot of usefulness at supersonic speeds as it can aid manoeuvring. Specifically for Stealth aircraft like the F-22 , it can allow for changes in attitude without the aircraft moving its control surfaces and compromising RCS.
It can also aid in supersonic manoeuvring if the controls are less than effective in executing a turn.
Also,TVC applications are different in different aircraft. The Su-30MKI for e.g. has a "fake" 3D system whereby its nozzles while moving in two dimensions are manipulated by the FCS in such a way that they act in three axis. This does mean however that its thrust is complexity off its flight path when its TVC goes active which also contributes to drag.
