And even when more F-35s have been fielded, F-15s could still fill a tactical role to help the Air Force carry out its mission. Boeing\u2019s new, single-seat F-15X design may be the Air Force\u2019s answer to that issue.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Very little has been made known about the F-15X initiative, which was first reported by Defense One, and the Air Force\u2019s <a href=\"https:\/\/www.airforcetimes.com\/news\/your-air-force\/2017\/01\/30\/pentagon-working-to-exempt-iraqi-f-16-pilot-trainees-from-trump-travel-ban\/\" target=\"_blank\">Pentagon officials<\/a> could not provide comment on it, only telling Air Force Times that \u201cthere is no acquisition program\u201d with respect to the new platform.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But multiple media outlets still reported this week that the F-15X was being pitched to the Air Force by Boeing. Alternatively, some reports state that the Air Force first solicited Boeing for the new fighter. Regardless, the possibility of a new platform to replace aging the fourth-generation F-15 fighters could alleviate the strain put on<a href=\"https:\/\/www.airforcetimes.com\/news\/your-air-force\/2018\/07\/20\/homeland-defense-missions-organizational-issues-kneecap-f-22s-potential-gao-says\/\" target=_blank> F-22 Raptors <\/a>and make up for the F-35s slow roll-out.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Created during the Cold War, the more than 40-year-old F-15 has been the U.S. Air Force\u2019s primary <a href=\"https:\/\/www.defensenews.com\/air\/2018\/07\/27\/nato-intercepted-a-russian-plane-over-the-black-sea-yesterday-but-us-f-15s-in-romania-will-be-sticking-to-their-training-mission\/\" target=\"_blank\">air-to-air fighter jet<\/a> for decades. The aircraft has been known for its range of operational roles, however, to include close-air support in the Global War on Terrorism.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dan Grazier, the Jack Shanahan Military Fellow at the Project On Government Oversight, writes extensively on military procurement, to include the F-35 acquisition. He said that while he can\u2019t comment on the specific designs of the F-15X, it is generally better to develop weapon systems from \u201can evolutionary approach.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1199\" height=\"631\" src=\"\/wp-content\/uploads\/2026\/08\/F15C.jpg.jpg\" alt=\"\" class=\"wp-image-58518\" srcset=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/F15C.jpg.jpg 1199w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/F15C.jpg.jpg?resize=300,158 300w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/F15C.jpg.jpg?resize=768,404 768w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/F15C.jpg.jpg?resize=1024,539 1024w\" sizes=\"auto, (max-width: 1199px) 100vw, 1199px\" \/><figcaption class=\"wp-element-caption\">U.S. Air Force Col.

It seems those requirements were met, based on the reported features.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The F-15X armament would be designed for a mixed air-to-air and air-ground-role, including \u201ceight air-to-air missiles and 28 Small Diameter Bombs (SDBs), or up to seven 2,000-pound bombs and eight air-to-air missiles,&#8221; according to The War Zone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The F-15X would allegedly be very affordable, as well. The aircraft reportedly costs roughly $27,000 per hour to fly. Meanwhile, the F-35A costs more than $40,000 an hour to fly, according to The War Zone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, The War Zone said the F-15X will have a 20,000-hour service life, meaning it could be flying for several more decades.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Still, Boeing officials have not outright confirmed they were pitching the F-15X.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe see the marketplace expanding internationally and it\u2019s creating opportunities then to go back and talk to the U.S. Air Force about what might be future upgrades or even potentially future acquisitions of the F-15 aircraft,\u201d Gene Cunningham, vice president of global sales of Defense, Space &amp; Security, told <a href=\"https:\/\/www.defenseone.com\/technology\/2018\/07\/heres-look-new-f-15x-boeing-pitching-us-air-force\/150039\/\" target=\"_blank\">DefenseOne<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Air Force has been considering retiring its F-15 Eagles for some time.
