Why do you term the article biased.
F-16: PAF has 77 of these fighter of which 14 odd fighter are very close to blk52.
Jf-17: from where did you get 22 per year. They are operating 2 squadron and they have facility to assemble 11-14 aircraft with China also manufacturing Jf-17 for them.
Jaguar: I too know that Jaguar will remain in service after 2017 but read carefully the scope of the article.
Mig-21 bison
ude plz, I don't want our pilots to fly these old design aircraft even after 2017.
J-10: China is developing WS-10 engine and it will mature soon. Every possibility of it to fly in PAF colors by 2016.
Su-35: I included this because there are talks, but I myself have doubt but there are many other aircraft waiting in line to get matured i.e. China always have PLAN B in place.
Mig 27 will start retiring from 2020 onwards.
