The latest stats out of the Pentagon show that UAV (or UAS--unmanned aerial systems--as they're known in the miltary) flight time is rising faster than ever. It climbed from 160,000 hours in 2006 to an estimated 250,000 this year--up 56%.
And with that has come increased spending, from $400 million in 2002 to more than $2
billion next year to an expected $3.5 billion by fiscal year 2010.
