I agree with need to induct a stealth platform and that it should be manufactured in-house.
However, I would stress the need to reduce JF-17's RCS as much as possible while keeping the expense within certain limits. Every little bit helps, and it does not matter what RCS is contributed by missiles attached to JF-17. Lowering RCS is important for its own sake and the argument about aircraft attachments contributing to RCS is not decisive in my opinion. How much does a single SD-10 contribute? What difference would be made by two BVR and two WVR missiles? Anything beyond that should be eliminated as much as possible. If JF-17's small size counts as a strength, then we might as well make it matter by lowering RCS as much as possible without going broke.
What if the RCS is already low enough that investment in reducing it further will lower it a bit beyond external weapons.
