Aurora (Colorado): Lockheed Martin hopes to begin rolling out early Block 4 capabilities to the F-35 this summer, a senior company official.
Chauncey McIntosh, vice president and general manager of Lockheed’s F-35 program, said at the Air and Space Forces Association’s AFA Warfare Symposium here that the company plans to drop an update to the F-35′s Technology Refresh 3 software, which will enable new features. The TR-3 software update will bring the aircraft type closer to being able to fly in combat, he said.
“Our warfighters are going to see a much higher increase of stability in that software” once the update is in place, McIntosh said. TR-3 is a series of upgrades to the F-35′s computer memory, processing power, and displays, which are intended to make the jet more capable and pave the way for a subsequent series of more substantial improvements known as Block 4.
McIntosh said in a briefing with reporters that Block 4 will bring the F-35 improved sensors, better sensor fusion, and an expanded array of weapons the fighter can carry. A previous Block 4 capability that was dramatically accelerated in the F-35 was the adoption of the automatic ground collision avoidance system, or auto-GCAS. That life-saving technology automatically pulls a jet up if the pilot is unresponsive and the jet senses it is diving into the ground. Officials began installing the capability in 2019.
TR-3′s rollout was snarled by lingering software and hardware problems that caused the government to refuse deliveries of dozens of new F-35s for about a year. The delivery halt was lifted in July 2024, after Lockheed Martin developed an interim version of the TR-3 software that would allow pilots to fly training missions, and then combat training.
It remains unclear whether F-35s will reach full combat capability this year. McIntosh said it will be up to the military services and international partners flying the jets to decide whether they are ready for combat. He did not directly answer when asked whether Lockheed will be able to deliver all the elements needed for a combat-ready designation by the end of this year.
Lockheed expects to deliver between 170 and 190 F-35s this year, as it works through the backlog from the TR-3 delays. That would be up from the roughly 110 it delivered in 2024.
