Most of those are domestic here in the United States.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pratt &amp; Whitney expects to have the remaining 25 percent of Turkish-made parts for the F135 qualified by the end of 2021, with all Turkish parts flushed from the system by the time engines for the 15th lot of aircraft roll off the line in 2020. At that point, about 20 percent of the F135\u2032s parts will be made by international vendors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Turkey, once a partner in the F-35 program and set to buy 100 F-35A conventional takeoff-and-landing models, was expelled from the program after accepting delivery of the Russian S-400 air defense system. At the time, the Pentagon hoped to <a href=\"https:\/\/www.defensenews.com\/air\/2019\/06\/07\/turkish-suppliers-to-be-eliminated-from-f-35-program-in-2020\/\" target=_blank>remove all Turkish suppliers<\/a> from the program by 2020, but it will take until 2022 for all contracts with Turkish companies <a href=\"https:\/\/www.defensenews.com\/air\/2020\/05\/12\/some-f-35-suppliers-are-having-trouble-delivering-parts-on-schedule-and-turkeys-departure-could-make-that-worse\/\" target=_blank>to come to a close<\/a>, said Greg Ulmer, head of Lockheed\u2019s aeronautics programs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Pentagon\u2019s F-35 Joint Program Office is \u201ccontinuing to work with Pratt and Whitney on steps to address the projected cost growth to ensure that the F135 Propulsion System remains affordable component of the F-35 air system,\u201d F-35 program executive Lt. Gen. Eric Fick stated in written testimony to lawmakers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Aside from the engine\u2019s forthcoming cost increase, the F-35 program is also grappling with difficulties in sustaining the F135 due to a power module shortage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On April 22, a total of 21 Air Force F-35As were grounded due to engine problems, said Brig. Gen. David Abba, who leads the F-35 integration office. Fifteen of those aircraft would be flyable with engine repairs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In a March interview, Bromberg told Defense News an array of factors had caused the engine shortage \u2014 which was further exacerbated by the COVID-19 crisis \u2014 and it would take time for corrective actions to work.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike most fighter engine programs, where an additional 20-30 percent of spare parts are maintained to ensure parts are available on the flight line or the depot, the F-35 program funds only about 10-12 percent, he said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe whole program was designed to eliminate intermediate maintenance and have a very robust international sustainment depot system that will be able to turn modules very effectively in the field,\u201d Bromberg explained. \u201cThe lower spares ratio, though, is making all that a little bit more exposed than you would have seen on another program. And we have to get through that.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another issue is that much of the planning and funding of spare parts, repair activity and logistics processes occur years before it is actually needed. For a program like the F-35, which has been operational for a couple years, those plans were based on estimates \u2014 not hard data from decades of flying and maintaining the plane.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That analysis left Pratt &amp; Whitney a bit behind when it came to fielding certain support equipment and technical data, which Bromberg said has since been delivered. In addition, the COVID-19 pandemic tacked on a three-month delay to the company\u2019s plans to ramp up engine production and sustainment efforts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe pick our best estimate. In some cases, you\u2019re over. In some cases, you\u2019re under. All that was in place a year ago,\u201d Bromberg said. \u201cBut in light of 2020, we probably didn\u2019t have enough margin.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The F-35 program is beginning to see increased output of F135 power modules due to the arrival of needed support equipment and technical data, Fick said. The F135 engine depot at Tinker Air Force Base, Oklahoma, plans to end a second shift by the end of the year, and the program office is also working to accelerate the activation of F135 engine maintenance at the Fleet Repair Center South East in Jacksonville, Florida.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe actions we have taken to date have begun to show benefit, as power module production at the Oklahoma City Air Logistics Complex has increased significantly in the last year and the projected readiness impacts, while still above our requirement, have started to stabilize,\u201d he said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Tinker depot plans to produce 40 power modules this year and ramp up to 60 modules in 2022, Abba said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, because the armed services will begin conducting 2,000-hour overhaul inductions in 2022, the program office estimates the costs to maintain the F135 will grow over the next five years, Fick stated.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>By the end of the year, Turkey will no longer supply parts for the F-35&#8217;s
