However, for security reasons, the PAF did not disclose the type of weapon systems to be acquired.
Sources said that these could be air-to-air weapons and air-to-ground platforms which will be fitted to the incoming PAF aircraft.
The Air Force is scheduled to commission eight brand-new AW-109 attack helicopters this year along with two F/A-50 jet fighters.
