That included increases of about $375 million on classified contracts with higher volumes, $80 million more for the F-22, and growth of about $55 million for the F-16 program.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But that growth was offset by a sales decline of about $310 million for the F-35, which Lockheed Martin said was due in part to lower volume.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lockheed halted acceptance flights of new Joint Strike Fighters immediately after a Dec. 15 mishap involving a newly constructed F-35B during an acceptance flight in Texas. Video of that mishap showed the F-35B hovering close to the ground before descending, bouncing and tipping forward until its nose and wing touched the ground. Its pilot safely ejected from the spinning fighter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Navy\u2019s investigation into the mishap, which is still ongoing, uncovered signs that a high-pressure fuel tube in the fighter\u2019s Pratt &amp; Whitney-made F135 engine had failed, a source familiar with the program told Defense News last month.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On Dec. 27, the Defense Department, Lockheed Martin and Pratt &amp; Whitney agreed to <a href=\"https:\/\/www.defensenews.com\/air\/2023\/01\/04\/new-f-35-engine-deliveries-suspended-amid-ongoing-investigation\/\" target=\"_blank\">pause delivery of new F135 engines<\/a> while the investigation continues to look for the root cause of the accident.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The pause in acceptance flights for new F-35s in turn halted deliveries. Lockheed Martin said last month it had been on track to meet its goal of 148 fighters delivered by the end of the year before the new planes were grounded. The company ended up delivering 141 F-35s in 2022.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Taiclet said in Tuesday\u2019s earnings call the company is waiting on the government and Pratt &amp; Whitney to finish the mishap investigation, and that the company expects to be notified it can resume acceptance flights and deliveries once that is done.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Taiclet said final production of F-35s \u2014 primarily at its facility in Fort Worth, Texas, but also in Italy and Japan \u2014 is continuing at the same pace before the mishap occurred. Lockheed is also continuing to order and receive parts to use in its jets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lockheed officials also touched on the company\u2019s plans to upgrade fighters with a new batch of hardware and software upgrades, which is expected to begin with the production of lot 15 fighters later this year.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jay Malave, Lockheed\u2019s chief financial officer, said the company hopes to begin retrofitting the existing fleet of F-35s with the hardware and software upgrades known as Technology Refresh 3 sometime next year. This will be part of Lockheed Martin\u2019s sustainment work on the F-35.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Air Force flew its first test F-35 with TR3 \u2014 which includes improved memory, processing power and displays, and will help get the fighter ready for Block 4 upgrades \u2014 earlier this month.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Taiclet said Lockheed plans to roll out more software releases and added capabilities in the months to come.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIt\u2019ll be able to handle more weapons, it\u2019ll be able to upgrade electronic warfare capabilities, it\u2019ll be able to accomplish more missions,\u201d Taiclet said. \u201cThe basic functionality of the aircraft alone is going to be elevated significantly by the insertion of this technology.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Lockheed Martin also previewed its plans for updating existing fighters with the hardware and software upgrades
