Northrop Grumman Corporation's first Block 40 RQ-4 Global Hawk high altitude long endurance (HALE) unmanned aircraft system (UAS) has completed envelope expansion flights, just six months after conducting its first flight.

The Block 40 aircraft will be equipped with the high performance Multi-Platform Radar Technology Insertion Program (MP-RTIP) sensor and is the first of 22 Block 40 Global Hawks assigned to Grand Forks Air Force Base, North Dakota.

The company also delivered on time the first development test MP-RTIP sensor to Edwards AFB for integration on the aircraft. The MP-RTIP sensor has completed radar system level performance verification on a surrogate aircraft, and will be integrated into AF-18, a Block 40 Global Hawk aircraft, for operational evaluation.

"The MP-RTIP-equipped Global Hawk illustrates Northrop Grumman's unique ability to create a system that will provide game-changing situational awareness for our warfighters with its unprecedented capability to detect, track and identify stationary and moving targets," said Duke Dufresne, vice president of the Strike and Surveillance Systems division of Northrop Grumman's Aerospace Systems sector.

"Our next step is to finalize sensor integration with the airframe and conduct the first flight of the full Block 40 system later this year."

"The MP-RTIP sensor has proven to perform above and beyond expectations," said George Vardoulakis, Northrop Grumman vice president of MP-RTIP. "The superior technology of the MP-RTIP will prove to be an invaluable resource to the warfighter."

Global Hawk's range, endurance and large payload capabilities are well suited to provide persistent surveillance with MP-RTIP. Flying at altitudes up to 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 types of weather, day or night.

As the world's first fully autonomous HALE UAS, Global Hawk is the platform of choice for a wide variety of sensors, foreign and domestic, meeting the global need for persistent ISR.
