The proof is in the performance figures, which can be seen to be clearly inferior to other aircraft of its size, particularly the Gripen. The JF-17 is a modern day F-20, arriving a quarter century too late. The RD-93 is the same basic engine as the RD-33 with some re-positioning of components. Sprinkling holy water on it does not reduce its fuel consumption. The JF-17 airframe was designed in the 70s using the technology of its day, and remains the same basic design, with modern avionics.
Before you get all bent out of shape, would you like to compare the three planes: F-20, JF-17 and Gripen, to see what the figures actually show? Telling things like they actually are takes only a bit of moral courage, that is all.
Or, since you are a Mod and I am only a (the most?) hated member, may be I should just concede?
Yeah, that is better: I accept that the JF-17 is a 4/4.5/5th generation jet fighter that is so over-engineered that it will be developed to carry far more payload.
There, I said it. Ramadan is coming up and I do NOT wish to fight with you or anyone.
Peace!
