BETHESDA, Md. - F-35 deliveries will restart later this year after Lockheed Martin reported no shipments during quarter one of 2024. Delivery delays continue plaguing the program due to software issues related to the Technical Refresh 3 (TR-3) upgrade.
Last summer, the Pentagon began refusing delivery of F-35s with the TR-3 modification because of a lack of suitable flight testing on the software. F-35 customers Belgium and Denmark followed suit pending correction of the TR-3 issue.
When Lockheed Martin resumes F-35 fighter deliveries in the latter half of 2024, the aircraft will include an interim "combat training-capable" software standard representing 95 percent of the full software load. Fully combat-capable jets will be available sometime in 2025.
The company projects deliveries of between 75 and 110 F-35 aircraft in 2024. The slow production start to 2024 continues from the previous year after Lockheed Martin delivered 98 total F-35s, its lowest shipment amount in the past several years.
