Thank to everybody, i know more about the situation of PAF. The problem of image from coups is really hard to solve and will take long time.
I read on the topic about LIFT, i think Phillipines can start by sending pilots to train, i think it will take shorter time, because even if PAF have FA-50, you will need to hire some foreign instructors for training. Maybe Phillipines can cooperate with Vietnam or Thailand, Indonesia for that.
About the new ship, it is a must-do, but also how about coast defense missile system, like K-300P Bastion-P. The range will be more than enough of a deterrent to protect fishmans go all small islands near you, besides it will take shorter time than ship training.
And back to the aircraft, FA-50 is chosen because the characteristics and the US system weapons. I know that the weapons in Phillipines Army are mostly American, but the PAF, sorry to said, but has almost no jet, so why not Yak-130 and after that Sukhoi and Mig from Russian, there will be a Maintenance Center in Vietnam of Sukhoi so it will be convenient.
