First F-35A Squadrons To Get Full Combat Capability In September

-"Twenty-six of those 108 aircraft will require a software-only upgrade, according to Harris. In addition to software modifications, 19 aircraft will also require new signal processor cards which the service says will take an average of three days to install and test. The service must install 18 aircraft with a newer helmet mounted display system, in addition to the processor cards and software, which will take 15 days to install. 

“The remaining forty-five aircraft will require significant hardware modifications in the form of a Tech Refresh 2 modification,” Harris states. “This modification consists of twenty-six major components and takes approximately 30 days per aircraft to install and checkout.”-
