Drones...
Think your right. Hans Blix found those drones (the ones he buried in the report and deleted from the US's copy) designed for spraying chem bio agents. They are essentially less sophisticated predator aircraft that can be launched without an airfield, essentially fired like a missile.
Still, they need to control them and I'm sure we have denied them any means to do that with our jammers and e-bombs etc.
