WASHINGTON \u2014 The U.S. Air Force on Friday conducted the first test flight of an F-35 loaded with a series of upgrades<\/a> known as Technology Refresh 3.<\/p>\n\n\n\n

The successful test flight marks a step toward loading the fighter with improved computer memory and processing power, and it lays the groundwork for a major modernization effort known as Block 4.<\/p>\n\n\n\n

The 461st Flight Test Squadron conducted the 50-minute test flight of the F-35A, which had the tail number AF-7, at Edwards Air Force Base in California, the F-35 Joint Program Office said Tuesday.<\/p>\n\n\n\n

Experimental test pilot Maj. Ryan \u201cBolo\u201d Luersen flew the jet to an altitude of 35,000 feet and at nearly Mach speed as he verified its airworthiness and system stability.<\/p>\n\n\n\n

Technology Refresh 3 includes software and hardware upgrades for the Lockheed Martin-made F-35 to improve its displays, memory and computer processing power, which will allow the fighter to store and process more data as well as run advanced software.<\/p>\n\n\n\n

\u201cThis is a significant achievement for the F-35 program,\u201d said Lt. Gen. Mike Schmidt, the F-35\u2032s program executive officer. \u201cTR-3 is the F-35\u2032s critical computer processing electronics upgrade that will continue to provide all our pilots with the capability they need to be successful against any adversary.\u201d<\/p>\n\n\n\n

In a November 2022 interview with Defense News<\/a>, Lockheed Martin\u2019s director of F-35 domestic engagement, Edward Smith, said TR-3 will provide the \u201cbackbone\u201d for Block 4.<\/p>\n\n\n\n

Those capabilities will include new sensors, the ability to carry more long-range precision weapons, more powerful data fusion, increased interoperability with other platforms, and advanced electronic warfare capabilities, the Pentagon said. This will improve the F-35\u2032s ability to spot, track and engage, as well as survive against, a variety of threats in the air, on the ground and in cyberspace, the Pentagon added.<\/p>\n\n\n\n

The development of TR-3 proved difficult and more expensive than expected. Last year, the Government Accountability Office said<\/a> the increased complication of TR-3 drove the cost of the Block 4 modernization effort up by $330 million in 2021.<\/p>\n\n\n\n

The JPO\u2019s statement acknowledged TR-3\u2032s \u201ctechnical complexity challenges,\u201d but said it \u201cis now on-track to deliver capability to the U.S. and its allies starting in 2023.\u201d<\/p>\n\n\n\n

\u201cLessons learned in the execution of the TR-3 program will be applied across the entire Block 4 modernization program,\u201d the JPO said.<\/p>\n\n\n\n

The first F-35s that will come with TR-3 already installed will be part of lot 15, which is now under construction. The finalized contract for lots 15 through 17 was announced Dec. 30<\/a>, and Lockheed expects to start delivering lot 15 fighters in the second half of 2023.<\/p>\n\n\n\n

The improved capabilities of this batch of fighters, including TR-3, are among several factors increasing the fighter\u2019s average cost.<\/p>\n\n\n\n

More developmental and operational test flights will continue throughout 2023 to ensure fighters loaded with TR-3 are safe, and the jet\u2019s combat capabilities work.<\/p>\n\n\n\n

Lt. Col. Christopher Campbell, commander of the 461st Flight Test Squadron and director of the F-35 Integrated Test Force, said TR-3 will \u201caffect nearly every aircraft feature\u201d in the future.<\/p>\n\n\n\n

\u201cToday\u2019s event was just the start of a comprehensive flight test campaign that will both verify and improve the safety, stability and performance of the whole F-35 weapon system in this new configuration,\u201d Campbell said.<\/p>\n","protected":false},"excerpt":{"rendered":"
