Here is the answer, With the Mirrage 2000 H upgradation, India opted for the Deep Upgradation, which included the Replacement of the Engine also and 499 MICA BVR, that's why the upgradation was so high. Pakistan is getting 8 brand new F-16 Block 52 from USA, without BVR thru FMS Channel. Why Pakistan is so desperate for F-16 Bloc 52 :-
1. Facts :- F-16 Block 52 equipped with Targeting Pod is needed against the war on terror, to locate and drop LGB with precission. --- Bull shit, because F-16 MLUed already have Sniper and JF-17 have WMD targetting Pod. In Reality the 40 F-16 A/B acquired in 80's from Peace Gate -1 and Peace Gate -2, of which 8 were lost due to iteration replacement due, since they have already completed their life Cycle, and the Block A/B whose airframe was designed for the A2A role, are subjected to the Ground attack role mostly are putting lot of strain on the Airframe. Even with the MLU, the avionics were upgraded, but not the engine, and airframe thus needs replacement soon.
2. Facts :- The Same formula applies for the Mirrage 2000 H -- Wrong, because Mirrage 2000 H airframe have life left for 15+ more years, and with the Mirrage UPG upgradation, its engine is been replaced with upgraded engine, and not only the avioinics.
