Unveilling Next-Gen High-Flying Global Hawk UAV

The first of 15 Block 40 Global Hawk unmanned aircraft reconnaissance system is unveiled by Northrop Grumman and U.S. Air Force officials June 25 in Palmdale, Calif. This newest addition to the Air Force's growing fleet of Global Hawks carries an advanced, all-weather multi-platform radar technology insertion program (MP-RTIP) sensor capable of detecting, tracking and identifying stationary and moving targets.

Northrop Grumman and the U.S. Air Force unveiled the next-generation of high-flying unmanned aircraft - the RQ-4 Block 40 Global Hawk - in a ceremony at Northrop Grumman's Palmdale, Calif., manufacturing facility.

"This unveiling of the first of 15 Block 40 aircraft is a significant step to fielding Global Hawk to Grand Forks Air Force Base, North Dakota, in 2010 and reaffirms our excellent track record of delivering Global Hawks since low rate production began," said Duke Dufresne, sector vice president for Northrop Grumman Aerospace System's Strike and Surveillance Systems Division.

"Carrying an advanced, all-weather multi-platform radar technology insertion program (MP-RTIP) sensor, the Block 40 aircraft will provide game-changing situational awareness for our warfighters with its unprecedented capability to detect, track and identify stationary and moving targets."

Use of the MP-RTIP sensor on the Block 40 Global Hawks marks the first time the active electronic scanned array (AESA) technology has been used on a high-altitude unmanned aircraft. AESA technology provides all-weather, day-night synthetic aperture radar mapping and ground moving target indicator capability.

"The Global Hawk system is in high demand by joint warfighters overseas, having successfully flown more than 31,000 hours since 2001," said Steve Amburgey, Global Hawk program director for the 303rd Aeronautical Systems Group at Wright-Patterson Air Force Base, Ohio. "Congratulations to the entire Global Hawk team for continuing to provide our service men and women with a reliable intelligence, surveillance and reconnaissance (ISR) system."

Designated AF-18, this Block 40 aircraft was the 27th Global Hawk built since the program's inception in 1995 and is scheduled to begin flight testing next month.

"This magnificent aircraft represents the future of Grand Forks Air Force Base. This and the rest of the Block 40 fleet will make significant contributions to the safety and security of our nation for years to come," said Sen. Kent Conrad of North Dakota. "I look forward to seeing this airframe on the Grand Forks ramp next year."

Global Hawk's range, endurance and large payload capabilities are well suited to support a variety of customers and missions, including environmental and Earth science research, homeland security, border and coastal patrol, hurricane and fire monitoring, and other disaster relief support activities. Global Hawk effectively provided imagery of the California wildfires in 2007 and 2008, and of Hurricane Ike in 2008.

Flying at altitudes of more than 60,000 feet for more than 32 hours per sortie at speeds approaching 340 knots, the MP-RTIP-equipped Block 40 Global Hawk can persistently see through most type of weather, day or night. As the world's first fully autonomous high-altitude, long-endurance unmanned aircraft system, Global Hawk is the platform of choice for a wide variety of sensors, foreign and domestic, meeting the global need for persistent ISR.

Northrop Grumman is the prime contractor for the Global Hawk and MP-RTIP programs and continues to move these technologies forward under the stewardship of the Air Force's Aeronautical Systems Center at Wright-Patterson Air Force Base, Ohio, and the Electronic Systems Center, located at Hanscom Air Force Base, Mass. Northrop Grumman's Norwalk, Conn., facility is the principal MP-RTIP radar developer along with principal subcontractor, Raytheon Space and Airborne Systems, El Segundo. The development MP-RTIP sensor is undergoing a radar system level performance verification on a surrogate aircraft, and will be integrated into AF-18 for an operational evaluation.

Northrop Grumman's Global Hawk program is based at its Aerospace Systems' Unmanned Systems Development Center in San Diego, Calif. The company performs Global Hawk sub-assembly work at its Unmanned Systems Center in Moss Point, Miss., and final assembly at its Antelope Valley Manufacturing Center in Palmdale.

The principal Global Hawk industry team includes: Aurora Flight Sciences, Bridgeport, West Va. (V-tail assembly and other composite structures); L-3 Communications, Salt Lake City (communication system); Raytheon Company, Waltham, Mass. (ground station); Rolls-Royce Corporation, Indianapolis (engine); and Vought Aircraft Industries, Dallas (wing).


Navistar Debuts Its Husky TSV At UK Vehicle Show

Navistar Defense has debuted its International Husky Tactical Support Vehicle (TSV) at the U.K. Ministry of Defence vehicle show known as DVD.

In April, the Ministry of Defence awarded the company a contract to provide 262 Husky vehicles. Organized by the Ministry's Defence Equipment and Support division, DVD offers attendees the chance to see vehicles in action on the show's off-road course.

Specially designed to meet U.K. urgent operational requirements in Afghanistan, the lighter and more mobile Husky is built to navigate the rough Afghan terrain, while offering added protection from ballistics fire, mines and roadside bombs.

The Husky, which is the medium variant for the TSV program, will be procured in three vehicle types: patrol, ambulance and command vehicle. Integrated with U.K. specific systems by Dytecna, the vehicle accommodates a four-person crew and is equipped with a MaxxForce D 6.0 L V8 engine, Allison five-speed automatic transmission, and also incorporates Plasan Sasa's armouring solution.

Last month, Navistar also delivered its first two Husky prototypes, ahead of schedule, to undergo final requirements testing before full production begins this summer.

"The Navistar team is going after an aggressive delivery commitment to provide our U.K. forces with the equipment they need as soon as possible," said Archie Massicotte, president, Navistar Defense. "Not only will we deliver quickly to support those in theater, but Navistar is prepared to rapidly incorporate design changes into our vehicles as in-theater threats evolve."
