Based on observations on the India-Pakistan skirmishes as of present, there are three categories which I believe that the Pakistani military should pile on, improve on, and add on respectively. Could be understated or overstated, of course.
1. Better things that should be piled on to further strengthen the advantages:
- Procure additional medium fighters, i.e. J-10CE in greater numbers to replace the older batches of F-16s;
- Procure additional light fighters, i.e. JF-17 in greater numbers that would entirely replace all the Mirages and F-7s;
- Procure additional AEW&C aircrafts, i.e. Erieye to enable greater degree of continuous radar coverage along the entire frontlines;
- Procure additional dedicated EW (ECM and ESM) aircraft platforms that would enable the soft kill of enemy munitions, as well as disrupting enemy aerial combat operations; and
- Procure additional aerial tankers to extend loiter duration of allied warplanes.
2. Not so good things that should be improved upon to remedy deficiencies and rectify problems:
- Procure more LRSAM batteries, i.e. HQ-9 and/or HQ-22 to intercept enemy missiles at long ranges;
- Procure more MRSAM batteries, i.e. HQ-16 and/or HQ-11 to intercept enemy missiles at medium ranges;
- Procure more SRSAM + CIWS + DEW batteries, i.e. HQ-17 + LD2000 to intercept enemy missiles and drone swarms at short/close-in distances;
- Procure land-based EW platforms to soft-kill enemy missiles and drone swarms; and
- Procure more MALE/HALE U(C)AV platforms to assist in reconnaissance, early-warning and strike missions.
3. Things that should be newly added into the inventory for greater battlefield impact:
- Procure 5th-generation fighters, i.e. J-35s and KAAN (if the latter can enter production in time), which would be useful for establishing technological parity with the enemy at the very least;
- Procure dedicated ELINT/SIGINT aircraft platforms to enable reconnaissance and early-warning in the EM domain; and
- Procure strategic ABM and AHM platforms to defend against potential enemy MRBM, IRBM and hypersonic missile attacks.
Oh, and one more thing - Greater degree of OPSEC enforcement is needed.
