Sure. But looking at all of the downed Israeli crafts, they are all $2-5m drones (all 18 of them).

For perspective: Patriot missiles cost $4m each.

The two(2) H450s are in that unit cost range. The others and the Heron variants range to $40 million. A not insignificant number of Iranian aircraft(such as the US-produced F-5s and C-130s acquired before 1979's Revolution) are low unit costs comparably to the UAVs("drones") lost here.

Attrition compared to US materiel(not material - although that too greatly burdens cost to the US) depletion such as the aforementioned Patriot does not favor the US for sustained operations in theater(let alone should a second theater contingency operation occur).
