General Atomics MQ-1 Predator
Probably the most famous UAV in service today is the MQ-1 Predator. It
is used mainly in the recon role but can carry two Hellfire missiles for point
strikes. This craft is actually remote-controlled by people and is not an autonomous
sort. The Predator has been in use since 1995, and has seen service in
the skies over Afghanistan, Bosnia, Serbia, Iraq, and Yemen.
Another quote
from Wikipedia:
"During flight operations the crew in the ground control station is a pilot and two
sensor operators. The aircraft is equipped with Multi-spectral Targeting System,
a color nose camera (generally used by the pilot for flight control), a variable
aperture day-TV camera, and a variable aperture infrared camera (for low
light/night). Previously, Predators were equipped with a synthetic aperture radar
for looking through smoke, clouds or haze, but lack of use validated its removal
to reduce weight. The cameras produce full motion video and the synthetic
aperture radar produced still frame radar images. There is sufficient bandwidth
on the datalink for two video sources to be used at one time, but only one video
source from the sensor ball can be used at any time due to design limitations.
Either the daylight variable aperture or the infrared electro-optical sensor
may be operated simultaneously with the synthetic aperture radar, if equipped."
One role that older, stripped down models of the Predator has been used
for in Iraq, is to be a decoy for Iraqi air defenses. They have also been successfully
armed with Stinger air-to-air missiles and have been used to "bait" Iraqi aircraft...
"An Iraqi MiG-25 shot down a Predator performing reconnaissance over the no fly zone
in Iraq on December 23, 2002, after the Predator fired a missile at it. This
was the first time in history a conventional aircraft and a drone had engaged
in combat. Predators had been armed with AIM-92 Stinger air-to-air missiles, and
were being used to 'bait' Iraqi fighter planes, then run. In this incident,
the Predator didn't run, but instead fired one of the Stingers. The Stinger's heat-seeker
became 'distracted' by the MiG's missile and so missed the MiG, and
the Predator was destroyed."

Northrop Grumman RQ-4 Global Hawk
In role and design, the Global Hawk is similar to the Lockheed U-2, the
1950s spy plane. It is a theater commander's asset to both provide a broad overview
and systematically target surveillance shortfalls. The RQ-4 air vehicle
is able to provide high resolution radar — that can penetrate cloud-cover and
sandstorms — and Infrared imagery at long range with long loiter times over target
areas. It can survey as much as 40,000 square miles (100,000 square kilometers)
of terrain a day.

Lockheed Martin/Boeing RQ-3 DarkStar
The DarkStar was designed as a "high-altitude endurance UAV", and made
use of stealth technology to make it harder to detect. The DarkStar was fully
autonomous, and could take off, fly to its target, operate its sensors, transmit
information, return and land without human intervention. The RQ-3 carried either
an optical sensor or radar, and could send digital information to a satellite
while still in flight.
