Wow...!!! I had no idea designing a 'stealth' aircraft is so easy. Damn...We Americans must have been doing something so wrong all this time to take so long and used so much money.
I can't say about time but you did use a ridiculous amount of money.
As far as the JF-17 is concerned, its even beyond funny to say its going to be a stealth fighter, if not for anything else then just the fact that if it ever is a stealth fighter, it will be another plane altogether. You just cant just fix a couple of things to make a fighter stealthy.
Room for improvement exists in
- use composites for light weight,
- go for higher thrust RD-93,
- increase number of hardpoints,
- develop a nice ECM suite,
- try to reduce RCS further if possible,
- IRST,
- next gen missiles,
- use an AESA radar,
etc., which I believe will be done over time as newer and better materials become available. Most of these facts are infact under consideration/work. For example, we have seen reports of higher thrust RD-93, ACM had said that they are trying to increase hardpoints, ECM suite is under development, I am sure with use of composites in Falco they will have the technology and experience to make it into the fighter jet, and we might see a different package for next batch of JF-17s.
So far so good. The plane is ready for induction with a descent package and further enhancements are already being looked into. Nice job PAF and PAC.
