Sorry bro this isn't the case. The PAF did order 18 Block-52+ with an option for 18 more, but these 14 F-16s are A/B models being acquired through the Excess Defence Articles (EDA) program. The option for 18 more Block-52+ still stands as well.
As most will know, the PAF originally planned for 50~75 Block-52+ in 2005 - but the earthquake and financial difficulties led to it being cut to 18 with an option for 18 more (36). However, I still believe there is scope for the original figure as long as production at Lockheed Martin continues for the next few years. This depends on whether new deals, such as Iraq, Romania, etc, are secured - certainly possible. The PAF did invest in raising infrastructure for Block-52+; and there is no doubt that it is an advanced yet highly matured as well as proven fighter.
