Newest F-35s Stalled by Slow Production of Key Parts

Defense News - Lockheed Martin is falling short of its commitment to deliver the upgraded F-35 Joint Strike Fighters this year, with less than half of the promised 52 jets equipped with Technology Refresh 3 (TR-3) improvements completed, according to Lt. Gen. Michael Schmidt, the F-35s program executive officer. Delays in the production of key components necessary for TR-3 hardware are hindering progress, with only 21 jets completed and the remainder awaiting these essential parts at Lockheed Martin Texas facility.

Schmidt identified slower-than-expected production of specific components as the primary challenge, emphasizing that the issue lies not with the quality of the hardware but the pace of production. The TR-3 upgrades encompass both hardware and software enhancements, including improved displays, computer memory, and processing power, setting the stage for a broader Block 4 upgrade to enhance the F-35s weapons capacity, target recognition, and electronic warfare capabilities.

Originally targeted for completion by April 2023, the TR-3 timeline has faced setbacks due to persistent software and integration issues. Schmidt suggested a potential completion date by mid-spring, though uncertainty surrounds this deadline, with previous estimates extending to June. The delay has led to the military inability to conduct necessary test flights, preventing the acceptance of newly built F-35s.

Lockheed Martin acknowledged the challenges, noting recent efforts to test the F-35s next software release for stability, radar, sensor, and weapons capability improvements. The company is also prioritizing the acceleration of hardware delivery from subcontractors contributing to TR-3 components.

Schmidt acknowledged the financial repercussions for Lockheed Martin due to its failure to meet contractual TR-3 delivery requirements, although specific penalties were not disclosed. While the current production issues affect new jets, the F-35 program has yet to commence retrofitting older jets. Schmidt emphasized the urgency for Lockheed Martin to swiftly address these challenges to avoid potential disruptions in the production line.

During a House Armed Services subcommittee hearing, Rep. Rob Wittman expressed concern over the repeated delays in fielding capabilities for the F-35, despite acknowledging its technological advancements. Schmidt attributed part of the problem to underperforming labs used for TR-3 testing, indicating efforts to enhance lab capacity and reduce the reliance on flight tests for discovery.
