PAF initially ordered 40 that were delivered in two batches of 20 each. They arrived on Dec 17th and 20th 2001 in Karachi via Chinese ships. A third batch of 8 was ordered and delivered in early 2003 along with 6 FT-7PG under Hand-Shake IV. That enabled PAF to equip No.17 Tigers, No.23 Talons and No.20 Cheetahs squadrons. There was an initial requirement for up to 80 aircraft but there were no subsequent orders. There were some two seats ordered later on as attrition replacements in the later years as well.
As far as attrition goes, it is not easy to know if the crashes are of F-7P or F-7PG sometimes but as many as 10 F-7PGs and 4 FT-7PGs have crashed
A LIFT jet should not cost more than our frontline fighter, in this case JF-17.
