schwit1 sends this news from Aviation Week: "A new U.S. Defense Department report warns that ongoing software, maintenance and reliability problems with Lockheed Martin Corp's F-35 stealth fighter could delay the Marine Corps' plans to start using its F-35 jets by mid-2015. It said Lockheed had delivered F-35 jets with 50 percent or less of the software capabilities required by its production contracts with the Pentagon. The computer-based logistics system known as ALIS was fielded with 'serious deficiencies' and remained behind schedule, which affected servicing of existing jets needed for flight testing, the report said. It said the ALIS diagnostic system failed to meet even basic requirements. The F35 program, which began in 2001, is 70 percent over initial cost estimates, and years behind schedule, but top U.S. officials say it is now making progress. They have vowed to safeguard funding for the program to keep it on track. Earlier this week, the nonprofit Center for International Policy said Lockheed had greatly exaggerated its estimate (PDF) that the F-35 program sustained 125,000 U.S. jobs to shore up support for the program."
