UAV

 


             Predator UAVs have been operational in Bosnia since 1995, where they have flown over 600 missions in support of NATO, UN and US operations. Predators have also been deployed as part of Operation Enduring Freedom in Afghanistan. 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 in Yemen, a Predator UAV was used to drop a Hellfire missile which destroyed a civilian vehicle carrying suspected terrorists.
             BLOCK 1 UPGRADE PROGRAM.
             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 RQ-1B, has been operational in the Balkans since April 2001. The Predator B has an operational ceiling of 45,000ft and maximum payload of 750 lb. Predator B has been flight tested with Hellfire II anti-armour missiles and can carry up to 14 missiles. Flight trials have also taken place with the General Atomics Lynx SAR (synthetic aperture radar) payload. Lynx also features ground moving target indicator technology. The USAF has also ordered two versions of Predator B with turbofan jet engines.
