There may be a press release available on www.lmco.com in the near future providing more details on the launch. Speaking of press releases, here's another Ada success story in the works from _my_ division of Lockheed Martin: ---------------------------------------------------------------- This information has been provided to the news media, with USAF approval. It refers to the initial software release in December; an updated software package has since been released. F-22 FIRST FLIGHT SOFTWARE PROGRAM COMPLETED FORT WORTH, Texas -- Lockheed Martin Tactical Aircraft Systems recently released the first complete Operational Flight Program (OFP) for the F-22 aircraft. The software package was electronically transmitted via a secure communication link to Lockheed Martin Aeronautical Systems in Marietta, Ga., where the F-22 is undergoing final assembly. The delivered OFP includes the computing power to control the major subsystems needed for the first flight of the aircraft, including the hydraulics and electrical power systems, flight controls, cockpit displays and engine controls. Elements of the software have been developed by Lockheed Martin Tactical Aircraft Systems, Lockheed Martin Aeronautical Systems and Boeing Military Airplanes Division. Lockheed Martin Tactical Aircraft Systems, Fort Worth, Tex., is responsible for system testing and integration of the OFP for the initial aircraft. The initial software release includes 275,000 lines of software code, of which Tactical Aircraft Systems developed about 57 percent. An additional 1,450,000 lines of code will be developed during Engineering and Manufacturing Development of the advanced avionics systems for the F-22. The flyable software developed by F-22 team members and major suppliers is integrated at Fort Worth and assembled into a single OFP for the initial aircraft. The OFP is loaded on the aircraft at the Marietta site using a Portable Maintenance Aid (PMA) that was developed by Lockheed Martin Tactical Aircraft Systems and Allied Signal. "The OFP assembly and load processes, demonstrated with this initial release, encompass a significant advancement in software supportability that will be used throughout the F-22 EMD, production, and field support phases," said Charla K. Wise, F-22 vice president and program director at Tactical Aircraft Systems. "The concept improves software reliability and maintainability, simplifies the software update process, and will reduce life cycle cost for the customer," Wise said. "The quality and integrity of the total software package is key to the success of any new fighter aircraft flight- test program. We are encouraged that major milestones in F-22 software development are occurring on schedule with no unforeseen problems." Lockheed Martin Aeronautical Systems used the initial OFP release for power-on testing of the first F-22 EMD aircraft. Two additional software releases are scheduled prior to the first flight of the F-22 in May, to incorporate changes recommended as a result of the integration testing at Fort Worth. The F-22 is being developed as the new air dominance fighter for the U.S. Air Force. # # #
