The attack aircraft has long been in use and today's mounts have benefited through the many decades of conventional warfare. Precision bombing, fast-attack and low-level strikes are the call-of-the-day, ensuring that one's enemy cannot retaliate at full strength. The GFP total ONLY includes fixed-wing attack / strike types (including light-class aircraft) though it excludes armed UCAVs / Drones (for the time being). Attack helicopters and gunships are NOT taken into account for this particular listing. Aircraft on order into 2016 are NOT taken into account.
