    USAF Announces New Major Deficiency On KC-46

    Lee Hudson The U.S. Air Force has upgraded an existing deficiency for the KC-46A Pegasus fuel system to Category 1. The service's program office first identified “excessive fuel leaks” in July after an air refueling test. The Air Force and Boeing are working together to determine the root cause and implement corrective actions. A Category 1 deficiency means the government has identified a risk that jeopardizes lives or critical assets. “The KC-46 Program Office continues to monitor the entire KC-46 fleet and is enhancing acceptance testing of the fuel system to identify potential leaks at the factory where they can be repaired prior to delivery,” according to an Air Force statement. Boeing is contractually obligated to rectify this deficiency at no additional cost to the Air Force. “We are disappointed to learn of this development and are already implementing assembly and installation improvements to correct the issue,” Boeing spokesman Larry Chambers said in a statement to Aerospace DAILY. “We have repaired several of the airplanes and will continue to implement repairs as needed. Boeing is working with urgency to address this issue.” The Air Force discovered several required fuel-system repairs, Chambers said. The fuel system is equipped with redundant protection for fuel containment. “In some cases with this issue, aircraft maintenance crews are finding fuel between the primary and secondary fuel barriers within the system,” Chambers said. The KC-46A program still faces other unresolved Category 1 deficiencies that involve the Remote Vision System (RVS) and the boom telescope actuator. The problem with the RVS is what the Air Force calls a “rubber sheet” effect that distorts the image on the visual display used by the boom operator during refueling operations. The actuator on the boom needs to be more sensitive to smaller receiver aircraft, such as A-10s and F-16s. Boeing has agreed to pay for the RVS design fix, while the Air Force will finance the design change to the actuator. “There's profound problems with the system,” Air Force Chief of Staff Gen. David Goldfein said March 3 during a Senate Armed Services Committee hearing. The service is certifying the aircraft to conduct airlift and medical evacuation missions. The plan is for the Air Force to employ the KC-46 in those roles while a long-term fix is being developed, Goldfein said. Goldfein told new Boeing CEO Dave Calhoun to focus on the KC-46 program, even as it is fixing the 737 MAX. Calhoun said the KC-46 is his top military priority. “I have seen a change in the behavior of that company since he took over, and so that's why we're more confident sitting here today that we have a serious fix on the table,” Goldfein said. “We're in final negotiations, so we can't go into any more detail than that. But I will say that it's looking better today than it was even six months ago.” https://aviationweek.com/defense-space/aircraft-propulsion/usaf-announces-new-major-deficiency-kc-46

    UK defense plans could take major hit from coronavirus fallout

    By: Andrew Chuter LONDON — Britain is facing some “distasteful medicine “ in an upcoming defense review, with question marks around money, allies, the industrial base, Defence Secretary Ben Wallace has warned. Giving evidence in a virtual session of the Parliamentary Defence Committee April 22, Wallace said there were some difficult issues to be addressed by a post COVID-19 Britain. “We will have to take some pretty distasteful medicine," he told committee members spread across the country in the first ever virtual session of the committee. "It's not just about sums of money. It is about cultural change — our relationship with our allies, what Britain's ambitions are going to be. Do we want to do everything? Do we want to do less? Do we want to let go of something? Do we want to bank on international consortia every time, or do we want to invest in our industrial base? All those are difficult questions. The defense secretary, who only recently recovered from COVID-19, said changing the culture is going to be as important as the sums of money made available to the Ministry of Defence in the integrated review. The government refers to it as an ‘integrated review' as it involves, defense, security, foreign policy and international development departments. Wallace said that whether the review is uncomfortable or not, his hope is the defense ministry will have a realistic amount of money available to undertake what it recommends. That's rarely been the case in previous reviews over the last 30 years or so, and few people here are expecting much different this time round. The issue is already complicated by the never-ending budget pressure at the MoD. According to the National Audit Office, the government's financial watchdog, the MoD already has a financial black hole for its equipment program of between £3 and £13 billion, or as much as $16 billion. John Louth, an independent defense analyst in the U.K., said one of the big challenges facing the MoD will be putting the procurement roadmap back together post COVID-19. “One of the real challenges will be re-profiling a schedule for procurement," Louth said. Everything is slipping to the right, and re-profiling is going to be difficult, particuarly as many of the programs are interdependent on other programs. That poses a large and difficult challenge within a restricted budget." The economic impact of the COVID-19 pandemic is likely to make more difficult allocation of cash to its various departments and ministeries in the next comprehensive spending review. That's not withstanding the fact that MoD personnel — nearly 3,000 at the last count — have been lauded for their excellent performance assisting the National Health Service and others, carrying out tasks ranging from delivering oxygen to hospitals to setting up and running command and control centers. In particular the MoD has been widely praised for rapidly constructing several field hospitals for COVID-19 sufferers, including a 4,000 bed facility at the Excel Centre in London. The site is well known to defense contractors, as it's the venue for the DSEI exhibition. The government announced last week it was pausing the integrated review to focus resources on the COVID-19 fight, without saying when the work would recommence. Wallace answered that question — twice. First he said the review would recommence next year; later he said the correct date was the end of this year, but he was seeking clarity on the exact timing. That decision will be taken by the Cabinet Office who are leading the review. They had previously ordered the review, which was initiated after Prime Minister Boris Johnson won the general election last December, be completed by July. That was a date many analysts and politicians, including the defense committee, thought was risky. “This [the delay] is welcome news. I want a longer period for the integrated review. I want us to examine our place in the world, especially post COVID. It's going to be a different world,” he said. Wallace, an ex-British Army officer, said the number one threat is lack of resilience. "I suspect it will be higher up the agenda as a result of the virus,” he said. The defense secretary said that unlike countries such as France, Britain wasn't bringing forward a number of programs to protect the industrial base. “We are though speaking to industry to ensure their cash flow is continuing. There is a lot of work on the books that we would like to keep going,” he told the committee. One industry executive who asked not to be named said, “cash is not an issue yet, but I'm prepared for that to happen. I'm bracing for extended credit being taken by our customers, but I haven't seen it yet.” The virus has had an impact on a number of major defense programs in the U.K., as people have been ordered to work at home or, if that's not possible, adopt social distancing requirements in the workplace. The impact that might have on defense suppliers ability to meet their contractual obligations, and subsequently their financial viability and and that of the supply chain, has been recognized by the government . A series of actions relating to paying suppliers has been in place since late March, with MoD procurement authorities advised to support suppliers in a range of ways to maintain cash flow. This includes forward ordering, payment in advance, interim payments and payment on order rather than receipt. The scheme has been well received by industry here. The executive said he applauded the government for its swift action, but acknowledged the challenge remains for protecting employment and cash flow. The executive did say though that more clarity was needed from the government over the availability of initiatives like the Corona Business Interruption Loan scheme for defense exporters. Wallace named BAE's F-35 and nuclear submarine activities as programs where the balance between COVID restrictions to keep workers safe and keeping production and cash flow moving were vital. “It's really important that we continue some work that's absolutely key. We also need to help these firms to get through the process, because cash flow is really important to their survival,” said Wallace. But it's not easy keeping your distance from colleagues if you are trying to build something like a nuclear submarine. As such, Wallace said submarine building activities in the U.K. had some of the highest absentee rates in the sector. BAE employs around 9,000 people at its nuclear submarine yard at Barrow in northwest England where it is building Astute-class attack submarines and working on the Dreadnought class of Trident nuclear missile boats. About 4,000 of the staff are working from home with over 1,100 employees now working on site – up from 800-900 last week. A BAE spokesperson said the employees were supporting critical work at the yard. Last week the company reported that HMS Audacious, its latest attack submarine to be built for the Royal Navy, had left the yard and was heading to the submarine base on the Clyde in Scotland. https://www.defensenews.com/global/europe/2020/04/23/uk-defense-plans-could-take-major-hit-from-coronavirus-fallout/

    The Army network plan to ‘compete everything’

    Andrew Eversden The Army recently conducted a critical design review for technologies it plans to deploy for Capability Set '21, one of the first pieces of its battlefield network modernization. In the review, the Army tested various elements of Cap Set '21, such as tactical radios and satellite terminals. Now, the service is making a series of capability trade offs — assessing affordability, technical maturity and density across formation. For example, the Army is weighing trade-offs between how many of its two-channel Leader radios and more affordable single channel radios will ultimately end up in an infantry brigade. Col. Garth Winterle, project manager for tactical radios at the Army's Program Executive Officer for Command Control Communication - Tactical, and Lt. Col. Brandon Baer, program manager for helicopter and multi-mission radios (HAMMR), talked with C4ISRNET about the decisions made during the critical design review and what these choices mean for the next batch of equipment known as Capability Set '23. This transcript has been edited for clarity and brevity. C4ISRNET: What decisions were made during the critical design review (CDR)? COL. GARTH WINTERLE: We went from a 100 percent classified network, hard to get people security clearances, very expensive, NSA-certification required for everything as part of the network architecture, to 75 percent secure but [with an] unclassified architecture at battalion and below. That really adds a lot of flexibility — not only in the addition of affordable commercial technologies that really add capability rapidly because that shaves about 24 months off potential fielding timeline if you don't have to go to NSA — but it keeps a very strong encryption using some of the same algorithms you use for NSA certified radios. It's secure. It's not unsafe. While it's unclassified, it's still very well encrypted. It's just a different way of doing business. So it really opens the door for a lot of different things. Plus, it really improves the ability to share data with coalition and multinational partners, who are also operating at that security level. C4ISRNET: Can you explain the Terrestrial Transmission Line of Sight (TRILOS) radio and the capability trade off you made? WINTERLE: The quantities were adjusted in order to afford more flexible, more expedient and pretty much more affordable options at the brigade level and below. There's a system called TRILOS. Think of a big dish on a portable tower. If you can line it up with another big dish on a portable tower over pretty long distances, you can get very high data throughput very quickly ... It's purpose is to connect large command nodes together and enable them to share data much, much better. So one of the things we looked at as part of the CDR, and we experimented with, is a new smaller expeditionary version. I talked about a giant dish on a portable tower. We went to the company we worked with called Silvus. They have a smaller, little four antenna radio, it's about the size of your home WiFi router [and] does the same thing in slightly less bandwidth. It's not as capable, but it performs that same function. And it's much, much lighter, much easier to pack out and we're actually putting those under quadcopters, like a drone, that are tethered [so] they operate off a line. So you can raise that up in the air and hold that radio up in the air and get really good range to connect two of those radios together to share data. By trading out one system of those large dishes on the tower, we're able to buy a significant quantity of the smaller systems. TRILOS, those dishes on towers, still remain in the architecture. But just by reducing the quantity marginally, we're able to really add a much more expeditionary much, much lighter, easier to set up. And we can buy it in larger quantities to increase the quantity out in the architecture to increase that capability. C4ISRNET: Can you describe how the Army intends to procure some of the Integrated Tactical Network components? WINTERLE: The intent is to compete everything. Single channel radios are a prime example. We're getting ready to invite vendors that have conforming radios to an industry day to basically have a radio run off. [We want them to] provide us enough radios so we can get them integrated and start assessing them against each other and against the current offering from the vendor that actually went through the experiment. It's going to be a fully competitive action. It is important to note though that I can't just go out and buy a new radio and, boom, I can field it. There is an amount of time where we are going to have to procure a limited quantity of the systems that went through the experiment until I can get those other radios through enough lab-based experimentation and integration, so that I know they work on the network. So even though they might be very similar [to] what we experimented with, there will be a delay so I can actually start fielding those to operational units. But [our] intent is to start that as soon as possible as part of the procurement fielding next year — this competitive run off of single channel radios. Anywhere else where there was a stand-in capability where we know from market research that there's other vendors, we'll perform the same sort of competitive actions. C4ISRNET: What are some of the lessons learned from Capability Set '21 that can be applied to Capability Set '23? WINTERLE: We're going to have a design review every year. The year prior to the preliminary design review, which is the year we're in right now for Cap Set '23, focuses on small-scale experimentation and a kind of assessment of ‘what are those technologies that going to compete to be added to the architecture as part of the preliminary design review' in April of next year. So we picked April. We just did this CDR in April. So the preliminary design review for Cap Set '23 is next April. We've partnered with the network cross functional team to help conduct research and development funded activities of certain key technology that they want to see added to the architecture in Cap Set '23. C4ISRNET: How has the Army's capability set testing structure been suited for COVID-19? LT. COL. BRANDON BAER: Traditionally, we do a large operational type test, where our approach has been lab-based testing, [cyber]-based testing, and then doing what we're calling soldier touchpoints. They're smaller experiments, but we're doing more of them. It gives us an opportunity to capture data, soldier feedback at different points of time. We call it developmental operations or DevOps. We can go back and tweak the stuff, fix any problems, get it back out there and continue to collect feedback. But I think it's extremely important due to current conditions with COVID-19, and everything else. Because everything has kind of gone into a large pause. And if we would have had a large pause during operational tests, it could be six months or a year before we have another opportunity to do that, where when you're doing multiple events ... we're capturing data at different times and different soldier feedback, you're not reliant upon one event. As we move forward, I see continuous benefits through that. https://www.c4isrnet.com/battlefield-tech/c2-comms/2020/05/13/the-army-network-plan-to-compete-everything/
