F-35 to Get New Software This Summer—but 

There’s No Date Yet 

Defense One

Lockheed Martin is aiming to release new software to U.S. F-35 jets this summer, a “step” towards the full, combat-ready version of the TR-3 upgrade, according to a company executive. ... The new suite, called Technology Refresh-3 is a software and hardware upgrade needed for Block 4 improvements. It was initially slated for completion in April 2023, but software-development problems have delayed the effort multiple times, and Lockheed execs and Pentagon officials haven't set a firm delivery date for the full package.
