I dont know what engine it uses, If it from US well you guys are lucky, and enjoying the use of MANNA status. If from China which i think is the most possibility, it is yj 62 IIRc a turbojet cruise missile, with added booster et al? Maybe Ukrain? I just dont know but its impossible for pakistan to make a miniaturized turbofan, sorry not according to me. Even if USA gives you the whole engine technology, productionalizing it would take from anywhere 5 to 7 years. If you want to make all parts inhouse with the technology? well forget it GOP would go bankrupt. not worth buying multi million costing machines to produce perhaps a high tolerance small actuator.
