Congress orders F-35 Software Plan

Congress ordered the Pentagon to establish an independent team consisting of subject matter experts to review the development of software for the Joint Strike Fighter program.

The House Armed Services Tactical Air and Land Forces Subcommittee asked the Pentagon to submit a report by March 3, 2014 as part of the committee’s markup of the 2014 defense budget. The F-35 software program has served as one of the largest challenges for program engineers to keep on schedule.

“The committee continues to support the F-35 development and procurement program, and believes a software development review by the Department will ensure that the F-35 program remains on schedule to provide a fifth generation capability in support of our national security strategy,” the Congressional language states.

The JSF program developmental strategy is, in part, grounded upon a series of incremental software “drops” — each one adding new capability to the platform. In total, there are more than 10 billion individual lines of code for the system, broken down into increments and “blocks,” F-35 program office officials explained.

“Software development remains a focus area of the joint program office. We have a solid baseline and we need to be able to execute on that,” said Joe DellaVedova, F-35 program office spokesman.

Software drop 2B is undergoing flight testing at Edwards Air Force Base, Calif., and Naval Air Station Patuxent River, Md; software Block 2B builds upon the enhanced simulated weapons, data link capabilities and early fused sensor integration of the Block 2A software drop, DellaVedova added.

“With Block 2B you can provide basic close air support and fire an AMRAAM {Advanced Medium Range Air to Air Missile}, JDAM [Joint Direct Attack Munition] or GBU 12 [laser-guided aerial bomb]. This allows the plane to become a very capable weapons system,” he said.

Overall, DellaVedova said the F-35 program office has been making substantial progress. Software drop 3I, which is a technical refresh of Block 2B, is slated to by ready by 2016.

“This is complicated and labor intensive work but this has leadership focus from industry and government to deliver on the promise of the F-35. With its stealth and its enhanced situational awareness, the F-35 will provide a backbone for our forces for generations to come. Our progress continues at a slow and steady pace and we are focused on completing things within the schedule and budget we’ve been given.”
