I do think PAF needs to get 50 Block III with a Chinese based AESA platform so that the PL15 can be utilised, and also get a "all western" avionics suite/mission computers(full platform) that will allow it to use the Raven or Grifo and the Meteor missile. This will allow the intellectual propery rights of both China, and western companies to be protected, preventing leakage of military secrets as it will be a closed ecosystem in both cases. In short, Block III shold be 100 units and not 50. The western systems will allow for better sales potential with some customers who are not familiar with chinese avionics etc.
