Let's put this figure into perspective:
The U.S.A. only have 57 x MQ-9 “Reaper” drones.
Each one of them costs 30,3 million $ . That's nearly as much as THREE A-10 “Thunderbolt” tankbusters together (at 11,8 million $ apiece), yet not 0,01 % as capable and as survivable as them.
This contract offers 120.551.310 $ for spare parts and airfield equipment for these 57 x MQ-9 “Reaper” drones.
That's (wait, let me think) 2.114.935 $ in spare parts and tool kits per individual drone. Or: 6,97 % of their unit price.
I don't find this excessively expensive, especially not if one considers that the whole “Reaper” program cost 11,8 BILLION $ . Those ~ 120 million $ in spare parts to keep them flying a life long only represent 1,02 % of that total value.
I don't agree that these drones (= coward, “israeli”-style assassination tools against defenseless Third World civilians, totally unworthy of non-djoows) should even have been built in the first place, but now I don't quite understand why the author, Mr. Mark Thompson, chose such an ironical title as “Enough About How Cheap Drones Are” ...
