  USAF Sees Five-Year Window To Invent A New Fighter Aircraft Industry

  By Steve Trimble and Lee Hudson The U.S. Air Force's vision to rapidly produce multiple fleets of advanced fighters the way Apple makes iPhones begins with an important change in plans for the secretive Next-Generation Air Dominance (NGAD) program. For three years, the Air Force analyzed how to replace the Lockheed Martin F-22 by 2030. The original plan—defined as the Penetrating Counter-Air capability in the Air Superiority Flight Plan released in 2017—called for developing a conventional replacement for the F-22, with a next-generation F-X fighter featuring a dazzling array of new technologies, ranging from adaptive cycle propulsion to advanced weapons and new sensors. As an extended, two-year-long analysis of alternatives neared a conclusion in mid-2018, the Air Force decided to shift to a new approach. The new strategy led Air Force leaders to drain about half of the $13.2 billion budget previously allocated to the NGAD program through fiscal 2024 in the Defense Department's five-year spending plan sent to Congress in March. Instead of launching full development of the F-X within that five-year window, the Air Force is developing a radical new aircraft design process—even as spending continues on deliveries of Lockheed F-35As, Boeing F-15EXs and a host of fighter upgrade programs. “We're at a good point to attempt something new because we have hot production lines for fifth [generation fighters]. [And] fourth-gen fighters [are] going through major multibillion dollar modernizations,” says Will Roper, the assistant secretary of the U.S. Air Force for acquisition, technology and logistics. “So it's a good time to try something new for a five-year window and see if we can create a new way to build airplanes for us that [is] between the building of one or two X-planes and the building of 1,000 units in a major defense acquisition program,” Roper, who is leading the new NGAD strategy, tells Aviation Week in an interview. Roper's comments on the sidelines of Aviation Week's DefenseChain Conference on Oct. 22, help clarify the dramatic shifts within the classified NGAD program over the last year. The U.S. Air Force essentially has delayed F-X development beyond the five-year spending plan to provide a window of time to invent a new business model for the combat aircraft industry, one ideally suited for a new era of air warfare with peer adversaries. The initiative will be supported by the new Program Executive Office for Advanced Aircraft that was established on Oct. 2. The office will be led by Col. Dale White, formerly the senior program director for the Northrop Grumman B-21 bomber development program at the Rapid Capabilities Office. Roper's vision for NGAD calls for a sharp break from the conventional acquisition approach adopted for the B-21, with a single prime contractor responsible for the full aircraft lifecycle, including at least a 10- to 15-year period between an initial contract award and delivering an operational capability. To Roper, the ideal model for NGAD is not another Western fighter program, but rather a consumer electronic device. Apple's customers buy an iPhone model that is designed to become obsolete within a few years, and replace it with a more advanced device, he says. The equivalent in the fighter business are aircraft designed to last perhaps 3,500 flight hours, which the U.S. Air Force buys in batches of hundreds and replaces in intervals of 10 years or less. “We want to retire airplanes when the next one is ready to be brought out—very similar to the iPhone model. So there's no reason to keep that old iPhone once you have the new one,” Roper says. Over the next five years, the Air Force wants to define the digital engineering-based approach to the hardware and common operating system approach to the software for the NGAD aircraft family. The goal is to attract new companies besides traditional defense firms to be involved in production, along with the specialized design units of the prime contractors such as Lockheed's Skunk Works, Boeing's Phantom Works and Northrop Grumman's Scaled Composites. “I could imagine companies that could build a few airplanes per month eventually breaking in and wanting to do it because there's an opportunity to do it frequently. And let's face it, design and cutting-edge airplanes [are] just wicked cool,” Roper says. https://aviationweek.com/defense/usaf-sees-five-year-window-invent-new-fighter-aircraft-industry

  Pentagon Rethinks Troubled F-35 Logistics System

  Lee Hudson August 12, 2020 The Pentagon is in the early stages of replacing the troubled Lockheed Martin F-35's autonomous logistics system with a new, cloud-based network, and hopes to get it up and running by the end of 2022. The Operational Data Integrated Network (ODIN) is intended to reduce workload and increase F-35 mission readiness rates by using a smaller, deployable, commercial and cloud-native architecture. Right now, F-35 users operate the Autonomic Logistics Information System (ALIS) that collects inflight information for maintainers to predict part failures. However, the problem-plagued logistics system has encountered numerous issues that range from directing unnecessary maintenance actions, taking too long to boot up and time-consuming data entry. For example, users told the Government Accountability Office (GAO) that electronic records are frequently corrupt or missing, resulting in ALIS signaling the jet should not fly. This occurs in cases where maintainers know the aircraft is safe for flight. Maintainers at one location told the GAO they experienced as many as 400 issues per week for one six-month period in 2019. The F-35 Joint Program Office (JPO) plans to begin installing hardware this September that can run software from both the legacy and new systems until ODIN is deployed fully. ODIN initial delivery is planned for September 2021. ODIN hardware is designed to have a 75% smaller footprint than the legacy system, and be approximately 94% lighter—50 lb. compared with 891 lb. Another radical difference between the two systems is F-35 prime contractor Lockheed owns ALIS development and the new network is being developed by the JPO. The JPO is using agile software development tools that allow rapid updates and improvements like how Apple updates its iPhones, while Lockheed employs waterfall development that allows for updates every 12-18 months. In January, the JPO hit its first milestone by moving existing F-35 data into a new, integrated environment that will support applications designed by organizations such as Kessel Run, one of the Air Force's software factories. Kessel Run formed a team called Mad Hatter and tasked it to build software applications to render F-35 logistics more user-friendly. A key complaint about ALIS was the lack of realistic operational requirements. In other words, user needs can become outdated. To address this shortcoming, the JPO partner nations agreed in January to update a requirements document for ODIN annually—if needed. Instead of crafting a rigid requirements document that will be outdated in 10 years, the new strategy calls for updating protocols based on reality, according to a program office maintenance systems expert. This strategy complies with the software acquisition policy of Under Secretary of Defense for Acquisition and Sustainment Ellen Lord. It calls for the users, developers and software designers to come together and produce a customer-centric design as development progresses. The requirements document features six capability needs: deployment planning and execution; unit maintenance planning; sortie generation; sustainment readiness; information management, and ODIN support. The document also includes 43 performance measurements that the JPO will use as metrics to track ODIN development. Beyond better programmatic planning, the Pentagon is facing a considerable obstacle as it transitions from ALIS to ODIN. The JPO is having trouble receiving technical data from Lockheed, Lord told the House Committee on Oversight and Reform. “While the department recognizes industry's interest in protecting intellectual property, there is technical data that the department has rights to and needs in order to enable effective organic sustainment,” Lord noted in written testimony submitted to the committee. In response to Lord's comments, Lockheed noted the company does not own all the logistics system's intellectual-property and data rights. “ALIS software is also government-owned, per contract requirements with Lockheed, and our suppliers retaining intellectual property and data rights to portions of software that were developed using industry's investment funds is in accordance with the Defense Federal Acquisition Regulations Supplement,” Lockheed spokesman Brett Ashworth tells Aviation Week. The Pentagon's overarching goal is to drive down F-35 sustainment pricing, which is where most of a program's cost resides. The government is still upgrading ALIS, an effort known as ALIS Next, before ODIN comes online to manage costs. ALIS Next consists of more regular software updates, instead of the program's current 12-18 month cycle. An updated version of ALIS, known as 3.5, is outfitted with 300 stability fixes, says F-35 Program Executive Officer Lt. Gen. Eric Fick. Air Force software developers and Lockheed Martin personnel are simultaneously continuing to issue ALIS software patches. ALIS Next provides an opportunity to reduce the amount of administrative personnel needed to support the logistics system's operations in the field. An important step to lowering the overall F-35 sustainment price is reducing the cost per flying hour. The goal is for the F-35A conventional takeoff and landing jet, the most popular variant, was $25,000 by 2025. “We are confident $25,000 is attainable, but it will require collaboration with the JPO, services, allies and our industry partners to reduce overall cost,” Lockheed F-35 Vice President and General Manager Greg Ulmer submitted in written testimony to the House Committee on Oversight and Reform. Over the past five years, the company has reduced a portion of the F-35's operations and sustainment costs by 38%. Lockheed is responsible for 39% of all F-35 sustainment costs, according to Ulmer. The company estimates it will drive down controlled cost another 50% in the next five years, and it is working with the government to achieve similar savings on the remaining 61% of flight-hour costs that are under the purview of the Defense Department and propulsion suppliers. Although in its infancy, ODIN is set to be the cornerstone for the next major wave of F-35 sustainment improvements over the next two years as ALIS is retired. https://aviationweek.com/defense-space/aircraft-propulsion/pentagon-rethinks-troubled-f-35-logistics-system
