As of September 2025, it was at least $6 billion over budget and years behind schedule, which was partly due to delays with the implementation of TR-3. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cBlock 4 means the aircraft\u2019s evolution, and TR-3 makes the F-35 as much as 25 times faster. It gives the jet\u2019s systems a much improved memory, and its tactical displays for pilots are capable of implementing all processes at a faster speed,\u201d Post said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As the F-35 Joint Strike Fighter program is struggling with cost overruns, manufacturing delays and supply chain bottlenecks, the U.S. Government Accountability Office said in a Sept. 3 statement the \u201cprogram plans to reduce the scope of Block 4 to deliver capabilities to the warfighter at a more predictable pace than in the past.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The delayed TR-3 which is critical to the Block 4 modernization effort \u201cwas the primary driver of late aircraft deliveries in 2024,\u201d according to the GAO. Last year, Lockheed Martin \u201cdelivered 110 aircraft. All were late by an average of 238 days, up from 61 days in 2023.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Under the plan, <a href=\"https:\/\/www.defensenews.com\/air\/2025\/02\/05\/key-tests-for-latest-f-35s-will-begin-in-2026-two-years-after-rollout\/\" rel=\"\"><u>dedicated operational tests<\/u><\/a> for the TR-3 upgrades are to begin in the U.S. in mid to late fiscal 2026, allowing to verify if the technology refresh is operationally effective.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><i>Editor\u2019s note: The story has been updated to clarify Lockheed Martin expects the Block 4 modernizations to be done by 2032.<\/i><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Following delays in the
