A
contract was awarded to General Atomics Aeronautical Systems in January 1994 to
execute the Tier II, medium-altitude endurance Predator programme. The Predator
system first flew in 1994 and entered production in August 1997.
RQ-1
Predator is a long-endurance, medium-altitude unmanned aircraft system for
surveillance and reconnaissance missions. Surveillance imagery from synthetic
aperture radar, video cameras and a forward-looking infrared (FLIR) can be
distributed in real-time both to the front line soldier and to the operational
commander, or worldwide in real-time via satellite communication links. MQ-1,
armed with AGM-114 Hellfire missiles, is the multi-role version which is used
for armed reconnaissance and interdiction.
Predator UAV Operations and Deployments
Predators
are currently in production for the US Air Force and are operational with the
USAF 11th and 15th Reconnaissance Squadrons. More than 125 Predators have been
delivered to the USAF. 36 additional MQ-1B Predators (with Hellfire missile
installation kits) were ordered in September 2007. Six Predator UAVs are in
service with the Italian Air Force. Italian company Meteor was responsible for
assembly of five of the six. The Italian system was deployed to Iraq in January
2005.
Predator
UAVs have been operational in Bosnia since 1995 in support of Nato, UN and US
operations and as part of Operation Enduring Freedom in Afghanistan and
Operation Iraqi Freedom, flying more than 500,000 flight hours on over 50,000
flights. The MQ-1 Predator achieved initial operating capability (IOC) in
February 2005.
General
Atomics is the prime contractor and the main subcontractors include: Versatron
/ Wescam for the electro-optical Skyball Gimbal, Northrop Grumman for the
synthetic aperture radar, L3 Communication for the wideband satellite
communications link, and Boeing for the intelligence workstation and mission
planning system.
In
February 2001, the Hellfire-C laser-guided missile was successfully fired from
a Predator air vehicle in flight tests at Nellis air force base, Nevada. In
November 2002, a Predator UAV was used to drop a Hellfire missile in Yemen,
which destroyed a civilian vehicle carrying suspected terrorists. A Northrop
Grumman Bat submunition was successfully dropped and a FINDER mini-UAV launched
from a Predator UAV in August 2002.
In
2011, GA-ASI signed two separate agreements with CAE and RUAG Aerospace
Services to offer the Predator B UAS to Canada and the Federal Republic of
Germany respectively.
In
June 2013, GA-ASI signed a memorandum of understanding with Fokker Technologies
to offer the Predator B RPA to support the Dutch Government's medium-altitude
long-endurance (MALE) capabilities. It further partnered with Spanish
engineering company SENER to offer Predator B RPA to the Spanish Government in
March 2015.
GA-ASI
and Rohde & Schwarz (R&S) partnered in May 2014 to integrate R&S'
air traffic control radios on the Predator aircraft. A pre-production due regard
radar (DRR) was tested aboard the Predator B RPA in February 2015.
GA-ASI
delivered three Predator B/MQ-9 Reaper systems to the French Ministry of
Defence, as of May 2015. France plans to acquire a total of 12 aircraft by 2019.
Predator B Skywarrior
In
May 1998 General Atomics was awarded a Block 1 upgrade contract to expand the
capabilities of the Predator system. System upgrades include development of an
improved relief-on-station (ROS) system which allows continuous coverage over
areas of interest without any loss of time on station, secure air traffic
control voice relay, Ku-band satellite tuning and implementation of an air
force mission support system (AFMSS).
The
upgrade also covers a more powerful turbocharged engine and wing de-icing
systems to enable year-round operations. The upgraded Predator, the Predator B,
was first operational in the Balkans.
In
August 2005, a version of Predator B, called Sky Warrior, was chosen for the
four-year system development and demonstration (SDD) phase of the US Army's
extended range / multi-purpose (ER/MP) UAV programme, comprising 11 Sky Warrior
systems, each with 12 air vehicles and five ground control stations.
Initial
operating capability was achieved in 2009. Two Block 0 Sky Warrior UAVs were
deployed to Iraq in April 2008. GA-ASI received $195.5m in funding from the US
Army for the low-rate initial production of the Sky Warrior unmanned aircraft
in July 2010.
Also
in August 2005, the US Department of Homeland Security / Customs and Border
Protection (DHS/CBP) ordered two Predator B systems for monitoring of the US'
south-west border. The first was delivered in late 2005, the second in
September 2006. Two further systems were ordered in October 2006, for
monitoring operations on the border with Canada.
MQ-9 Reaper Hunter /
Killer UAV
In
March 2005, the USAF awarded a further contract for the system design and
development (SDD) of MQ-9 Reaper Hunter / Killer. 21 MQ-9 have been ordered and
eight delivered to the USAF. The
first USAF MQ-9 squadron, the 42nd Attack Squadron, was formed in March 2007,
based at Creech AFB in Nevada.
The
USAF first deployed the MQ-9 Reaper to Afghanistan in October 2007 for
precision airstrikes. The MQ-9 Reaper flew its first operational mission in
Iraq in July 2008.
The
MQ-9 Reaper has an operational ceiling of 50,000ft, a maximum internal payload
of 800lb and external payload exceeding 3,000lb. It can carry up to four
Hellfire II anti-armour missiles and two laser-guided bombs (GBU-12 or EGBU-12)
and 500lb GBU-38 JDAM (joint direct attack munition). In May 2008, a USAF
Reaper successfully test dropped four Raytheon GBU-49 Enhanced Paveway II 500lb
bombs, which have laser and GPS guidance.
The
MQ-9 sensor payload can include the General Atomics Lynx SAR (synthetic
aperture radar). Lynx also features ground moving target indicator technology.
The Predator is to be flight tested with a L-3 communications tactical common
datalink (TCDL).
In
September 2006, the UK requested the foreign military sale (FMS) of two MQ-9
Reaper systems with Lynx SAR, multi-spectral targeting systems and one ground
station. Deliveries began in mid-2007 and the RAF deployed the system in
Afghanistan in November 2007. In January 2008, the UK requested the sale of ten
additional MQ-9 systems.
In
August 2008, Italy requested the sale of four MQ-9 Reaper systems with three
ground stations. The USAF accepted the final MQ-1 Predator aircraft in
March 2011.
In
June 2015, the Italian Directorate for Air Armaments and Airworthiness (DAAA)
selected CAE to develop upgrades to a Predator UAS Mission Trainer for the
Predator A and Predator B/MQ-9 aircraft developed for the Italian Air Force.
Delivery of the trainer is expected in 2017.
System Components
A
typical Predator system configuration would include four aircraft, one ground
control system and one Trojan Spirit II data distribution terminal. The
Predator air vehicle is 27ft in length and has a 49ft wingspan. The system
operates at an altitude of 25,000ft and at a range of 400nm.
The endurance of the air vehicle is more than
40h and the cruise speed is more than 70kt. 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 150nm and UHF and Ku-band satellite data links.
Payload
The surveillance and reconnaissance payload capacity is 450lb
and the vehicle carries electro-optical and infrared cameras and a synthetic
aperture radar. The two-colour DLTV television is equipped with a variable zoom
and 955mm Spotter. The high-resolution FLIR has six fields of view, ranging
between 19mm and 560mm.
The Raytheon multi-spectral targeting system (MTS-A) is
fitted on the MQ-1/9 Predator. The MTS-A provides real-time imagery selectable
between infrared and day TV, as well as a laser designation capability. MQ-1
can employ two laser-guided Hellfire anti-armour missiles with the MTS.
The
Northrop Grumman TESAR synthetic aperture radar is fitted on the MQ-1 and
provides all-weather surveillance capability, has a resolution of 1ft. Other
payload options, which can be selected to meet mission requirements, include a
laser designator and rangefinder, electronic support and countermeasures and a
moving target indicator (MTI).
The USAF equipped a number of MQ-1 and MQ-9
Predators with a version of the Northrop Grumman airborne signals intelligence
payload (ASIP) in 2010. Northrop Grumman was awarded a contract for the
development and flight testing of the system on an MQ-1 in April 2008. ASIP has
also been tested on the U-2 reconnaissance aircraft and fitted on the RQ-4
Global Hawk.
Ground Station
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 together with satellite and line-of-sight ground
data terminals.
The ground control station can send imagery data via a
landline to the operational users or to the Trojan Spirit data distribution
system which is equipped with a 5.5m dish for Ku-band ground data terminal and
a 2.4m dish for data dissemination.
Operation
Predator follows a conventional launch
sequence from a semi-prepared surface under direct line-of-sight control. The
take-off and landing length is typically 2,000ft. The mission can be controlled
through line-of-site data links or through Ku-band satellite links to produce
continuous video.
Video signals received in the ground control
station are passed to the Trojan Spirit van for worldwide intelligence
distribution or directly to operational users via a commercial global broadcast
system. Command users are able to task the payload operator in real-time for
images or video on demand.
