Azad Pakistan , look like you don't know ABC of Stealth... Let me educate you once again...
1. External weapon contribute 3-4 Sq M RCS. Even If you can bring down RCS of JF17 to 0.1 Sq M, fully loaded FC1 will have RCS of 3-4 Sq M.
2. F15 silent eagle is huge plane (Size of Su30), It can carry only 4 missile under its internal weapon bay (If only Internal weapon bay is used), How much a small plane like FC1 or LCA can carry in its Internal bay?? one missile?? One missile can not Guarantee kill.
3. With every country going AESA, its difficult for LO Aircraft to remain stealth.
4. I have just talked bout Frontal RCS, I have not yet talked bout IR signature and other RCS.
The Moral of the story is:
1. Stealth/VLO FC1 is myth and useless.
2. Pakistan must start new project to develop a stealth fighter (from scratch)
3. Experiments on LO JF17 is good for Pakistan R&D sector, they must do it. But ppl like you must not boast on capability of it.
4,. R&D work never go waste, even if you fail, you will get enormous knowledge.
5. Pakistan have china, Pakistan must learn as much possible from china, no one know what will happen in future.
I have read many things but this beats most of it...
Reducing RCS is waste of time thanks to AESA. Well, the whole relationship with AESA or radar with RCS is wrong. If you can see 1 m2 on say 10 meters then you can see it on maybe 20 meters if it is 4 m2. So reducing the rcs helps buying range. Maybe you would also advice India to dump all MKI (that one has definatly huge rcs and lots of weapons)...
I do not think that frontal section increased with that much with more stores. Please provide source.
