Well, I suppose it depends in part on which aircraft Pakistan plans on using – I had a feeling they were planning on giving their Navy some of the new JF-17s, so I suspect there would be no problem with them. The problem comes when you consider the P-3s and subs – the subs probably should not be too much of a problem, since they are Agostas, so the Chinese Exocets should not be a problem – but the P-3s could prove a big problem. I suppose it all depends on who does the integrating, the Chinese could probably get the P-3s to fire their missiles, but the US might not be keen on the Chinese playing with their aircraft.

Not so sure about the need to refit all the radars – the missiles integrate with the ships systems, not the other way round (in part because the choice of missiles evolves over time, as newer missiles come on the market), so you should basically be able to ‘plug and play’ the missiles. Also, the Chinese missiles would probably be the Exocet clones, so (logical deduction, which could be completely wrong!) just about anything that can fire Exocets should be able to fire the Exocet clones.
