I didn't like it before, but I'm starting to understand the PAF's approach of controlling costs to this more aggressive degree. Basically, they could have spent more to add more features and capabilities, but if the gains are marginal improvements (versus closing fundamental gaps), then why take on the cost?
It's better to focus on getting the fundamental capabilities for the lowest cost possible. In the case of the Block-3, the main outcomes were an AESA radar, VLRAAM integration, an ECM kit, and HMD/S. I think the HMD/S is the only area the PAF is willing to spend money on because it offers a net-new capability in the form of HOBS AAM. The only reason why it can't is because there are no options at this time.
Basically, if there's any money left for further improving the Block-3, it's reserved for the HMD/S (be it from China, Europe, or Israel via 3rd parties). That's the only missing capability gap.
