I was told that if anything a more powerful variant of the RD-93 called the RD-93M would be considered if any new powerplant was. Whether that engine is a concept at present, whether it is testing or about to leave the drawing board, whether it is thrust vectoring I don't know. I wasn't told anything more about this engine. I suspect if it is to be eventually be born however, it will probably be a variant of the RD-33MK, which powers the MiG-35. It certainly fits the bill. After all, the major difference between the RD-93 and the RD-33, from which it was developed, is the repositioning of the gearbox to below the engine. I have also heard past word about the PAF looking into TVC for the JF-17, so I guess the case becomes stronger. To me at least the RD-33MK looks like a very good engine, and if the RD-93M is a variant of this powerplant, I think everyone will be very happy.
