Why would they allow Turkey to make money from upgrading American equipment when they can earn this money themselves? The US will eventually allow Pakistan to get the V upgrade, the question is whether it will be too late by then.
Pakistan would have to sweeten the deal by buying enough American Ammo and services (Specifically Lockheed products primarily but all the major 5-6 defense contractors) across the three services to make it worth it, and get the defense contractors to lobby for the upgrade.
Buying 18 used F-16C/D plus the following upgrades for 90 planes (5 Squadrons)
1. Auto GCAS upgrade for F-16s
2. A Lockheed supplied and supported overhaul facility in Pakistan for the F-16s
3. F-16 Drogue refueling system
4. Triple Missile launcher
5. Towed decoy
6. A new engine for each plane plus a few extras
7. IRST21 pod and/or Sniper targeting pod
8. 500 AMRAAMs and 500 Aim-9Xs
The key components from turkey from the Ozgur upgrade would be the AESA Radar, jamming pods, mission computer, avionics, cockpit, smart helmet (which could be carried over into the KAAN program when the F-16s retire)
Beyond the F-16:
More Bombardier Global 6000 for the Havasoj program and Saab Globaleye program and Embarer 1000 for the MPA, all non-American products but all have American components.
Avionics modernization for the C-130s
Seahawk (MH-60R) helicopters with lightweight torpedos, ESSM, Rolling airframe missile for the Jinnah Class frigates
Upgrade to the P-3 Orions to extend their lives (upgrades that could be transferred over to the Sea Sultans when the lives of the P-3s run out)
