Good News, it seems PAF has regained or will soon regain its original strength of 4 AWACS + 1 Transport / Trainer Saab-2000.
PAF took delivery of another Saab-2000 AWACS in 2016. There was news of this delivery on Civil Aviation websites also.
@Bilal Khan 777 confirmed that it was meant as replacement of one of the completely destroyed Saab-2000 with a new Radar & other Equipment ordered from Sweden.
We know from past posts, news & released pictures that:
040 was operating soon after Kamra attack in an exercise.
025 was repaired extensively(As seen in Wajahat Saleem's show & pictures of 23rd March 2016 Parade Rehearsals)
One of 045, 049 was damaged beyond repair while other was damaged slightly and repaired.(as per statement of defense secretary in parliament).
So it appears 019 will act as replacement and be converted to AWACS, while 029 will act as Transport / Trainer.
