6. Most
military drones don't bomb.
Although
decapitation strikes may get all the headlines, the vast majority of the time,
drones are used for intelligence, surveillance, and reconnaissance -- what the
military calls ISR. The U.S.
Navy's first high-altitude drone can relay black-and-white photos covering
roughly half the Persian Gulf; the Global Hawk's advanced radars make detailed
images of the Earth and attempt to sniff out chemical or biological agents for
telltale signs of weapons of mass destruction. Soon, the Gorgon Stare drone
will "be looking at a whole city, so there will
be no way for the adversary to know what we're looking at, and we can see
everything," according to Maj. Gen. James O. Poss.
7. Attack
drones require more boots on the ground.
Most
unmanned aircraft flown by the U.S. military require not just a ground-based "pilot,"
but also a platoon of surveillance analysts (approximately 19 per drone),
sensor operators, and a maintenance crew. Some 168 people are required to keep
a Predator drone aloft -- and 180 for its larger cousin, the Reaper -- compared with
roughly 100 people for an F-16 fighter jet. To keep up with the demand, the Air
Force has trained more drone operators than pilots for the past two years. The
upside is that, according to the Congressional Budget Office, drones "are
usually less expensive than manned aircraft" ($15 million for a Global Hawk
versus about $55 million for a new F-16),
though costly sensors and excessive crashes can negate the difference.
