Following successful integration of Hellfire missiles, an
armed version of Predator was deployed in Afghanistan during
Operation Enduring Freedom (OEF) in 2002. These aircraft are
designated MQ-1. Officially, the Predator A system was declared
"operational" only in 2004, ten years after it began
flying with the US Military. Predator UAVs are currently operated
by the US Air Force and Italian Air Force. By September 2007
the Predator fleet accumulated a total of 300,000 flight hours,
over 80 percent in combat missions and this pace is increasing.
In October 2007 alone, the Predator fleet performed 12,000
hours. More recently the USAF fielded the Reaper,
a larger more capable UAS based on an outgrowth of the Predator
platform.

Every Predator system consists of four unmanned aerial vehicles
(UAVs), a ground control station, a satellite communications
terminal and 55 personnel. The Predator Unmanned Aerial Vehicle
(UAV) is equipped with reconnaissance equipment and weapons
to provide persistent Intelligence gathering, Surveillance,
and Reconnaissance (ISR) capability. It is designed to perform
over-the-horizon, long-endurance, medium-altitude surveillance,
reconnaissance, and weapons delivery on mission endurance
of up to 40 hours. Predators have also been tested with optionally
expendable Finder mini-UAVs, facilitating a high flying
Predator to perform low-altitude recce missions without descending
and becoming vulnerable to enemy fire.
The production version of the Predator aircraft is equipped
with a turbo-charged Rotax 914 engine producing 105 horsepower.
The aircraft measures 27 feet (8 m') long, 6.9 feet high.
The Predator weighs 1,130 pounds (512 kg) empty, and 2,300
(1,043 kg) pounds Maximum Take Off Weight (MTOW). On a typical
mission the Predator cruises at an altitude of up to 25,000
feet and 70 – 84 mph, with maximum speed of 135 mph.
The Predator can maintain a 40 hours patrol over a large area,
at a distance of 400 miles from its operating base. The payload
capacity is 450 pounds (204kg) internal plus 300 lbs (136
kg) in external stores, and fuel capacity 665 pounds (100gal./286
kg). Enhancements for Predator include replacing the original
electro-optical/infrared sensor ball with an improved system
that adds a laser designator/rangefinder and adding wing hard-points
and wiring to carry and launch two Hellfire missiles. These
improvements evolve Predator to into an armed reconnaissance
platform which retains all the capability of a traditional
ISR asset, and adds a direct strike capability.

As a multi-sensor platform, Predator is equipped with an EO/IR
and SAR payloads. The for day/night imagery, the system uses
the Raytheon AN/AAS-52 Multisensor
Tactical System (MTS) electro-optical stabilized turret,
offering day and night operation. When weather conditions
limit its operations, for coverage of a large area, Northrop
Grumman's TESAR Synthetic Aperture Radar is used. The
UAV uses line of sight communications datalink or satellite
communications, to receive flight instructions and transmit
video streams, still images and other sensor information to
the mission control center. Information gathered by a Predator
can be shared instantaneously with commanders around the world
via Rover remote receiving
terminals. Imagery products are distributed worldwide via
defense communications satellites or commercial services,
utilizing the Trojan Spirit II intelligence distribution satellite
terminals and DCGS intelligence support network.
During
operations in Iraq the Air Force used both in- and out-of-theater
ground control stations, with beyond-line-of-sight air vehicle
control, to fly Predator. This gave the Combined Forces Air
Component Commander great flexibility since he could increase
capability and have redundant control using up to five ground
control stations at multiple locations. Three orbits were
controlled, via remote operations, from the United States.
Four simultaneous Predator orbits were flown over Iraq, and
an additional orbit operated over Afghanistan. Combining the
reach back operation in support of combat operations in-theater,
used for both Global Hawk and Predator significantly reduced
troop deployment and improved system availability, reduced
theater force protection needs, and saved significant operating
costs. Moving data rather than people was a demonstration
of “networked” operations and another example
of the rapidly evolving use of UAVs. This enhanced capability
shortens the kill chain and dramatically reduces the opportunity
for targets to flee if tactical aircraft are unavailable to
deliver weapons.
The USAF preferred to operate the Predator with "pilot
in the loop". During operation in Iraq and Afghanistan,
Predators are flown by USAF pilots located in Nellis AFB California.
The aircraft and mission payloads are controlled via satellite
data link. Sensor feeds are received in the mission control
center back in USA via satellite where they are processed
and analyzed. The imagery and intelligence products are distributed
on the global intelligence network (DCGS) and are accessible
to USAF and other forces worldwide. Raw images can also be
used, as they are received directly by units in theater, using
video links. The air vehicle is equipped with UHF and VHF
radio relay links, a C-band line-of-sight data link which
has a range of 150 nautical miles and UHF and Ku-band satellite
data links.
The UAV Ground Control Station is built into a single 30ft.
trailer, containing pilot and payload operator consoles, three
Boeing Data Exploitation and Mission Planning Consoles and
two synthetic aperture radar workstations On board communications
equipment include satellite and line-of-sight) ground data
terminals. The Ground Control Station can send imagery data
via a land line to the operational users or to the Trojan
Spirit data distribution system. The Trojan Spirit II data
distribution system is equipped with a 5.5m dish for Ku-band
Ground Data Terminal and a 2.4m dish for data dissemination.
In February 2009 the U.S. Air Force (USAF) MQ-1 Predator unmanned aircraft fleet have surpassed the 500,000 flight hour milestone, 87 percent of those hours were flown in combat. “In July 1994 we delivered the first MQ-1 Predator, and next month we are scheduled to deliver the 200th Predator aircraft to our U.S. Air Force customer,” said Thomas J. Cassidy, Jr., president, Aircraft Systems Group, General Atomics Aeronautical Systems, Inc. “In less than two years, flight hours for all Predator A type aircraft have almost doubled and are now approaching 20,000 hours per month, with USAF MQ-1s flying nearly 85 percent of those hours. The 500,000 hour milestone was achieved by USAF Predator P-143 on February 16 while it performed an armed reconnaissance mission in support of Operation Iraqi Freedom (OIF). This particular aircraft has flown over 330 combat missions in the two-and-a-half years it has been deployed.
August 2006:
The fleet of MQ-1 Predator unmanned aerial systems achieved
a milestone of 200,000 flight hours in July 2006. According
to the manufacturer, General Atomics, more than three-quarters
of that time spent in combat for a total of 10,961 combat
missions. According to Thomas J. Cassidy, Jr., president,
Aircraft Systems Group, General Atomics Aeronautical Systems,
Inc. “the Predator aircraft have flown nearly 100,000
flight hours over the past two years and are currently flying
more than 6,000 flight hours per month while maintaining the
highest operational readiness rates in U.S. Air Force inventory.”
May 2007:
The US Air Force received five Predator
Mission Aircrew Training System (PMATS). By June 2007
seven PMATS systems will be based at the Creech Air Force
Base in Indian Springs, NV to support the newly established
432nd unmanned
systems wing, the first US Air Force wing totally dedicated
to Predator and Reaper operations.
