Dear Sir u have given the young poster a befitting reply and ur reply has got the toughness of American Cowboy culture. However perhaps poster was trying to explain benefits of getting TFX over J31.
To me if u do not object the J31 is present for PAF and TFX is the future. We need both. Many have commented here that J31 shall be availble in time frame of 2021-24 but facts show that the jet is ready for production and all improvements have been done. Now the ball is in PAF court, when they will order. I believe that if jets are ordered before end of 2017 the deliveries shall start by 2019. PAF should realize the threats and go for it.
We should start to induct J31 with start of Rafael deliveries to IAF as so far honestly we do not have any modern jet which can challenge Rafael as I believe that once Rafael deliveries are started then Super Skhoi project will take off. Then in medium to long term either f16 block 70 or Grippen NG shall be also there.
We should have at that time sufficient number of JF17-Block 3, up graded previous JF17s and J31 to counter new threats.
For TFX the doubts are still there as due to Turkey's tilt to wards religion the EU and West has started to sabotage their projects especially related to areas where they are still not self sufficient further chances of any internal turmoil in Turkey are still there. May be sane move shall be to go for indigenous next generation fighter jet with the help of Turkey, China and for some tech we may go for SA help.
