FORT WORTH, Texas, Oct. 28, 2004. Engineers at Lockheed Martin's Mission Systems Integration Lab (MSIL) here have begun the initial integration testing of the Communication, Navigation and Identification (CNI) suite for the first flight of the F-35 Joint Strike Fighter.

The initial tests of the first-flight CNI suite verified the operation of UHF and VHF communication, radar altimeter, intercom, integrated caution and warning, and identification-friend-or-foe capabilities. Over a three-week period the team tested each capability, generating early confidence in the system's design and stability. Assembly of the first F-35 is under way, with first flight planned for 2006.

"The F-35's first-flight CNI system is being integrated into the Mission Systems Integration Lab and initial tests were flawless," said Bob Elrod, Lockheed Martin executive vice president and F-35 JSF program general manager. "The success of these early tests highlights the contributions and teamwork of multiple team partners, and helps to keep the F-35's first-flight schedule on track."

The F-35's first-flight CNI system was designed and integrated by Northrop Grumman's Space Technology sector, mostly using current-inventory federated systems. Northrop Grumman developed a customized interface adaptor unit to serve as the "interpreter" between these off-the-shelf components and the F-35's displays and controls. Hardware and software integration of the F-35's integrated CNI suite will begin soon at Northrop Grumman's Radio Systems lab facilities in San Diego, Calif.

The F-35 is a next-generation, supersonic, multi-role stealth aircraft designed to replace the AV-8B Harrier, A-10, F-16, F/A-18 Hornet, and the United Kingdom's Harrier GR.7 and Sea Harrier. Three F-35 variants -- a conventional takeoff and landing (CTOL), a short-takeoff/vertical-landing (STOVL) and a carrier variant (CV) -- each derived from a common design will ensure that the F-35 meets the performance needs of the U.S. Air Force, Marine Corps, Navy, the U.K. Royal Air Force and Royal Navy, and allied defense forces worldwide, while staying within strict affordability targets.

Lockheed Martin is developing the F-35 in collaboration with its principal partners, Northrop Grumman and BAE SYSTEMS. Northrop Grumman's Space Technology sector is leading an international team that is providing the F-35's CNI suite.
