with or without CSF ?
Jordanian F-16s might be of interest again.
The OHP Class which could be available are FFG-42, FFG-40, FFG-55, FFG-56, FFG-59 and FFG-45.
F-16s would still be a potent platform, if an upgrade can be arranged, but what good are the OHP class frigates?
How has the OHP the PN last received been performing?
Is it a decent enough ASW platform, or would the PN be better off seeking the LCS the USN is considering retiring? It really comes down to the sensors carried by the platform, more than the platform (but even then the age of the platform is also an issue). For a decent ASW frigate, CAPTAS-4 Towed Sonar, a decent ASW helicopter, and the kinds of Command and Control systems to coordinate an attack or a defense.
Either way, the PAF can’t give up procuring the J-10s. Just like the JF-17s, they are essential to maintaining the PAF’s flexibility. The PAF may only be able to acquire a couple dozen F-16, 40-50 used F-16s tops, so it’s no reason to give up on the J-10s and JF-17s. They will constitute the bulk of the PAF.
Btw, is there any indication the US is even receptive to these requests. This could be another saga that gets dragged on for years like the AH-1Z. Considering the current Pakistani government is looked upon favorably by the current US Administration, the Pakistani military probably didn’t see any harm in putting in a request. They probably figured, might as well give it a chance.
