This testing, which is similar to ones conducted previously on the RQ-4A configuration, is designed to simulate forces experienced due to specific "gust load" winds during a mission.

The enhanced wing is one of a number of system improvements prime contractor Northrop Grumman is making to Global Hawk to accommodate an increased payload carrying capability while maintaining current platform performance specifications.

Vought's work scope includes design development, fabrication, assembly and structural testing of the new wing. The company is currently scheduled to build seven production wings for the new RQ-4B model, with options for future production lots of the new wing configuration.

Vought has built two RQ-4B prototype wings and is producing another article for testing ultimate loads. For the RQ-4A model, Vought built two prototype and nine production wings under its Low Rate Initial Production (LRIP) contract with Northrop Grumman.

"This is an important step in developing the new Global Hawk wing," said Erich Smith, Vought's senior vice president, program management and business development. "We look forward to delivering the first enhanced wing to Northrop Grumman in July on schedule."

Global Hawk has completed more than 200 missions and logged over 4,000 flight hours in the Global War on Terrorism.

It began flying missions over Afghanistan in 2001, playing a key role in supporting Operations Enduring Freedom and Iraqi Freedom. Global Hawk enhances the U.S. military's ability to prevail in all types of operations, from sensitive peacekeeping missions to combat operations.

The new RQ-4B wing is 130.9 feet long and weighs about 4,000 pounds. It will be the longest wing ever delivered from Vought's Dallas facility.
