  A-10 Enhanced Wing Assembly Replacement Program Comes To An End

  A-10s Get New Wings Workers at the Ogden Air Logistics Complex at Hill Air Force Base have installed the last of 173 new wings on A-10 Thunderbolt II aircraft, finalizing a project that started in 2011 with aircraft 80-0173. The ALC's 571st Aircraft Maintenance Squadron swapped wings on 162 A-10s as part of the A-10 Enhanced Wing Assembly replacement program. The remaining 11 were installed at Osan Air Base in the Republic of Korea. The new wings are expected to last for up to 10,000 equivalent flight hours without a depot inspection. In addition, a better wire harness design was created for easier wing removal and to lessen the chance of damaging the wing during the process. “From a warfighter point of view, bringing this program to a successful conclusion was a significant accomplishment for the entire enterprise team,” said Stephen Zaiser, 571st AXMS director. Working on an aircraft that has been flying for nearly 40 years wasn't without challenges. The modifications included having to make new parts for the fuselage and having to bring other A-10 parts up from the 309th Aerospace Maintenance and Regeneration Group at Davis-Monthan Air Force Base, Arizona. “At the end of the program, making sure we had all the pieces and parts that we needed to make that happen required a really significant team effort,” Zaiser said. “I think the fact that we produced the aircraft so successfully is a testament to the whole team, the special program office, Boeing and others that were a part of making it all work.” Lt. Col. Ryan Richardson, 514th Flight Test Squadron commander and A-10 test pilot, flew the functional check flight on the last A-10 to receive the new wings to deem the aircraft airworthy. “It flew great and passed all the FCF checks,” Richardson said. “It's unusual to have an airplane in production for as long as this one was and have it come out and fly as well as this one did.” Introduced into the U.S. Air Force aircraft inventory in 1976, the venerable A-10 is the only production-built aircraft for close air support. The aircraft was made to fly close to the ground in support of friendly ground troops, drop heavy loads of weapons, attacks armored vehicles and tanks, and can be called in to attack enemy ground forces. With heavy stresses put on the wings over the weapon system's lifetime and with its full-service life still unknown, the Air Force decided to replace some of the fleet's wings in order for the weapon system to remain airworthy. In 2007, Boeing was awarded a $1.1 billion contract to build replacement wings at its Macon, Georgia, plant that will allow the aircraft to continue flying into the late 2030s. “The A-10 Special Program Office, in partnership with the Ogden ALC, is poised to keep the aircraft flying for the foreseeable future,” said Michael Hackett, A-10 SPO chief engineer. http://www.aero-news.net/index.cfm?do=main.textpost&id=e3fe8bb4-6d74-4d69-845e-d6e204fcfbe7

  The US Air Force is in no hurry to commit to a next-gen fighter design

  By: Sebastian Sprenger BERLIN — The U.S. Air Force is taking its time to settle on a next-generation fighter design, awaiting instead lessons learned from the F-35 jet and playing the field with promising technologies, according to a senior service official. Options being kicked around are still in the conceptual stage, as America's newest fighter, the fifth-generation F-35, is only now “coming off the line,” according to Lt. Gen. David Nahom, the Air Force's deputy chief of staff for plans and programs. “We're not in a hurry,” Nahom told Defense News on the sidelines of the International Fighter Conference, an air power-themed confab of industry and government officials held in Berlin, Germany. He noted that expected deliveries of the F-35 and the relatively young age of the F-22 fleet enables the service to be picky about moving forward with the envisioned Next Generation Air Dominance weapon. In short, the Air Force wants to keep its options open for as long as possible for a weapon whose combat punch will lie not in a single aircraft but rather in the amalgamation of hardware and software, an airborne concerto of data clouds, artificial intelligence, and boundless interconnectivity. “We don't want to get too stuck into a platform,” Nahom said. “It's a very different way to approach it.” Still, the service plans to lay the groundwork for boosting the domain of information and data — organizing it, analyzing it, sharing it — as a key element for future aerial warfare. To that end, officials will include a “significant investment in the digital backbone” in the next budget request, Nahom said. As the Air Force studies its options, service analysts have shied away from the term “sixth-generation” aircraft as a successor to the F-35 because it's unclear what breakthrough technology will be created next. “What are the characteristics of sixth-generation? I don't know,” Nahom said. “Stealth is important,” he added, referring to one of the advertised features of the F-35. “But speed is important, too.” The service aims to develop a new capability quickly once the theoretical legwork is done. That is why there is a renewed emphasis now on engineering processes and algorithm development that Nahom said will have to unfold much faster than under previous aircraft programs. Air Force acquisition chief Will Roper has put down a marker to develop an aircraft within five years. “Based on what industry thinks they can do and what my team will tell me, we will need to set a cadence of how fast we think we build a new airplane from scratch. Right now, my estimate is five years. I may be wrong,” he told Defense News in an interview in September. The service's information-heavy tack on future aerial warfare echoes two European projects aimed at building a next-generation weapon: the British-led Tempest and the Franco-German-Spanish Future Combat Air System. Both programs also lean on the the premise that data clouds, driven by artificial intelligence, can turn flying pieces of metal into breakthrough weaponry. In the case of the continental program, an envisioned “combat cloud” will be “the ocean between the islands of the platforms,” French Maj. Gen. Jean-Pascal Breton said at the conference. But Nahom noted a difference in the American way of thinking when it comes to piercing contested airspace — a key skill required of all future warplanes. While the Europeans seem to perceive the task as popping dispersed bubbles of ever-improving air defense systems, the U.S. view is that any airspace may be contested at any given time. That means a next-generation aircraft will be constantly engaged in the mission of punching its way through enemy defenses, like finding the holes in a never-ending series of Swiss cheese, Nahom said. https://www.defensenews.com/global/europe/2019/11/18/the-us-air-force-is-in-no-hurry-to-commit-to-a-next-gen-fighter-design/
