The Jinnah class is the continuation of the Pakistani Indigenous warships project.I'm really confused by the terms "Jinnah class", and "Babur class".The only thing I understand is that it's 2 different projects.
Just like with the Turkish Milgem project,4 corvettes,4 light frigates,7+ destroyers.
Pakistan started with 4 Babur class corvettes then 4 or more Jinnah frigates after that maybe an indigenous destroyer.
