  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 In other words, user needs can become outdated.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

  Unmanned systems, anti-drone tech featured at South Korean arms expo

  By: Brian Kim SEOUL — Unmanned defense systems and advanced weapons to counter drone threats dominated an arms exhibition held outside of Seoul, South Korea, this week. During the biennial DX Korea event, which ran Nov. 18-20, local defense companies showcased their cutting-edge unmanned and counter-drone technologies. Hanwha Corporation, a leading developer of guided-missile technology and subsidiary of Hanwha Group, displayed its new family of laser weapons systems. The company unveiled two types of anti-drone laser weapons: one for installation on light tactical vehicles, and the other a laser-based anti-aircraft weapon gun in a container configuration. The latter, designated as Block I, can be modified to a Block II self-propelled system, but specifications were not disclosed. Hanwha Corporation is a partner in an anti-drone laser weapons development project led by the government's Agency for Defense Development. “The laser-based anti-aircraft weapon is a new concept of armament to shoot down small aerial targets, including drones and multi-copter with a light source laser,” the company said in a news release. “Prototypes of the laser weapon variants are under development jointly with the ADD.” The company also displayed anti-jamming equipment that can be fitted in tactical guided missiles as well as on military vehicles and naval vessels. Hanwha Systems — also an affiliate of Hanwha Group — displayed a mock-up of its personal air vehicle, Butterfly, under development with U.S. air taxi startup Overair. In partnership with Overair, Hanwha Systems plans to fully develop the electric vertical-takeoff-and-landing, or eVTOL, vehicle by 2040, with an eye toward military sales. “With technologies to be accrued from the development of commercial eVTOL, we will push for developing a military variant capable of conducing multiple missions, including special operations, transport and assault,” the company said in a news release. Meanwhile, Hyundai Rotem presented its HR-Sherpa unmanned ground vehicle designed to support infantry troops. The six-wheel drive vehicle can move autonomously or via remote control to perform missions such as surveillance, medical support and chemical detection. It has a payload of 600 kilograms and a combat weight of 1,800 kilograms. It is equipped with airless tires and powered by a battery with an operating time of six hours when traveling at 5 kph. LIG Nex1 showcased the third version of its Sea Sword unmanned surface vessel for riverside defense, following other naval variants. The vessel adopts a high-speed monohull design and is constructed with fiber-reinforced plastic. Equipped with a diesel engine and a waterjet propulsion system, the boat can sail at a maximum speed of 40 knots and has an operational endurance of up to eight hours at 15 knots. An indigenously developed autonomous navigation system enables the vessel to carry out surveillance and reconnaissance missions based on a preprogrammed route. Hanwha group was ranked 32nd in Defense News' list of the top 100 defense companies in the world. LIG Nex1 was ranked 68th, while Hyundai Rotem was ranked 95th. https://www.defensenews.com/industry/techwatch/2020/11/20/unmanned-systems-anti-drone-tech-featured-at-south-korean-arms-expo

  South Korean military to upgrade ‘friend or foe’ ID capability

  By: Jeff Jeong SEOUL — Thousands of South Korean jet fighters, helicopters, warships and missile systems will be fitted with sophisticated identifications technologies by the mid-2020s under a major weapons upgrade program, according to the military and defense companies. For the $2.2 billion deal to switch the decades-old Mode-4 Identification Friend or Foe, or IFF, system to the latest Mode-5, South Korea's arms procurement agency has started issuing a request for proposals. “The number of equipment eligible for the Mode-5 upgrade account approximately 2,000 related to 70 weapons systems,” according to a spokesman for the Defense Acquisition Program Administration. “The request for proposals will continued to be issued separately by the types of weapons systems over the coming weeks.” The upgrade program is in line with the transfer of IFF systems to the Mode-5 version by the U.S military, as the South Korean military conducts key operations with U.S. forces on the Korean Peninsula under the authority of the Combined Forces Command. By 2020, all NATO nations are required to introduce the Mode-5 systems, using advanced cryptographic techniques to secure their systems against electronic deception by adversaries. “This is a huge program as for the numbers and budget, and is strategically important to upgrading the battlefield capability of the South Korean military and its joint operations with allied forces,” said Kim Dae-young, a military analyst at the Korea Research Institute for National Strategy. “The new encrypted system will allow South Korean and its allied troops to work safely together, reducing the risk of friendly fire incidents, and it will also offer commanders a better view of the battlefield,” Kim added. IFF works by sending coded signals, with equipment on friendly planes and ships able to receive and instantly decode the encrypted challenge message, then send the appropriate response to identify themselves. Three South Korean defense manufacturers are competing for the IFF upgrade contract by teaming up with foreign IFF developers. They are Hanwha Systems, teaming up with U.S. company Raytheon and Hensoldt of Germany; LIG Nex1, with Italy's Leonardo and Thales of France; and Korea Aerospace Industries, joining hands with BAE Systems of the United Kingdom. Unlike the installation of the Mode-4, the technologies of which belong to foreign IFF makers, domestic companies are involved in the Mode-5 systems development and will locally produce the equipment for cost-effectiveness and sustainable integrated logistics support, according to Defense Acquisition Program Administration officials. Hanwha Systems, a leading defense electronics company formerly known as Samsung Thales, claims it has the advantage of having know-how related to IFF integration and design. “Our company was in charge of almost all Mode-4 upgrade programs in cooperation with foreign partners,” said Yoon Seok-joon, a consultant with Hanwha Systems' avionics business team. “Through the experience, we have much better knowledge of IFF design and functions than other local competitors. This is a clear advantage.” LIG Nex1, a precision missile developer, formed a task force in 2016 for Mode-5 upgrade work to seek related technology for localization. As a result, the company successfully localized a Mode-5 system for its KP-SAM Shin-Gung (or Chiron) shoulder-launched surface-to-air missiles with the help of Thales, which is contracted to provide Mode-5 technologies for ground weapons systems. “Based on the successful development of a Mode-5 device for Shin-Gung, we're now able to independently develop Mode-5 equipment for other weapons systems, such as Hybrid Biho air defense system; Chunma short-range surface-to-air missile; and TPS-830K low-altitude radar,” said Park Jung-ho, program manager of LIG Nex1's Mode-5 upgrade team. To help facilitate the certification of its Mode-5 systems by the U.S. Defense Department, LIG Nex1 recently signed an agreement with the U.S. defense system certification contractor KBR. Korea Aerospace Industries is expected to win contracts for Mode-5 devices to be fitted on advanced aircraft, including F-15K fighters, T-50 trainer jets and Surion utility helicopters. KAI develops the Surion platform. “We own thousands of platforms around the world with this product, so we have lots of experiences in the U.S. and other countries as well as with this IFF piece of equipment,” said Rob Peer, president of BAE Systems in Korea. “It's advanced technology with low weight, low power and cost effective. All of those things make it very effective.” Peer stressed that he feels BAE Systems' Mode-5 is the best fit for the systems of the F-35 fighter jet, which South Korea is to deploy in the coming years. https://www.defensenews.com/global/asia-pacific/2018/09/24/south-korean-military-to-upgrade-friend-or-foe-id-capability
