Update: F-35 test fleet struggles with low readiness rates as key deadline approaches

Pat Host, Washington, DC

Key Points
The F-35 programme's test fleet has a fully mission-capable rating that is roughly 10% of its goal
This could make it difficult for the Pentagon to make an educated decision on whether to enter full-rate production
The Pentagon's Lockheed Martin F-35 Lightning II Joint Strike Fighter (JSF) test fleet has a fully mission-capable rate of 8.7% compared with an 80% goal, causing one watchdog to question whether the programme can accomplish all of its initial operational test and evaluation (IOT&E) test points before the phase ends.

Dan Grazier, military fellow with the Project on Government Oversight (POGO) watchdog group in Washington, DC, said the Pentagon plans to make its full-rate production (FRP) decision by the rapidly approaching end of fiscal year 2019 (FY 2019) or early FY 2020. The fiscal year changes on 1 October. If the F-35 programme cannot accomplish all its IOT&E test points by this deadline, Grazier said the Pentagon cannot make an informed decision on FRP.

The FY 2016 Director of Operational Test and Evaluation (DOT&E) report called for an 80% availability rate to conduct an efficient IOT&E and support sustained combat operations. According to an F-35 programme briefing slide provided by POGO and dated 19 July 2019, the 8.7% rate is an improvement from 4.7% in May.

  • Are software-defined ground stations the next big leap? Kratos is betting on it.

    Are software-defined ground stations the next big leap? Kratos is betting on it.

    Nathan Strout WASHINGTON — Software-defined payloads have revolutionized how industry and the government approach satellites. So why not software-defined ground stations? That's the question Kratos is asking. On Oct. 20, the longtime Pentagon contractor with experience building satellite support systems unveiled its new OpenSpace platform — a family of virtual products that applies the software-defined approach to the ground station. OpenSpace uses an open standards, cloud-based system that can be continuously adjusted to mission needs without having to install new hardware. Pentagon officials often complain that the nation's current satellite ground architecture is stymied by stovepiped, custom-built proprietary ground systems. The department has said it plans to move to an enterprise ground system, but it's not there yet. Kratos hopes that OpenSpace can at least be part of the solution. Because the platform is software-based, satellite operators no longer need to use custom-built hardware to connect to and control their on-orbit systems. Instead, OpenSpace virtualizes the ground system in software, effectively allowing it to be linked up to any antenna with a digital converter. “It's a big announcement from our perspective in that it's going to address a lot of the key issues that are challenging the space industry across the board, and especially some of the issues that the defense and government world is going through,” Neil Oatley, Kratos' vice president for marketing, told C4ISRNET. Software-defined payloads have opened up new possibilities in the space industry. Previously, satellites were designed to be rather static tools — once placed in orbit, it becomes all but impossible to physically replace the payload hardware or refigure the software. That means that the system you launch is the system you've got, regardless of whether your mission needs change or you want to do something new with your orbital tech. The Defense Department is investing in capabilities that could eventually allow physical access to operational satellites via robotic space vehicles, but that's still in development. All that is just to say, when the military builds a satellite, it builds it with the expectation that the space-bound payload will be largely static over the lifetime of the spacecraft. In other words, it will do the mission it was meant to do, and not much else. “When you look at the ground today, it's the one area where we're really stuck back in 2G-type technology,” said Phil Carrai, president of Kratos' Space, Training and Cyber division. “Systems are stovepiped. They're static. They're built with custom hardware. They have software-specific technologies that are dedicated to specific satellites. And that's really making them unable to play in the coming new world.” Building a new, custom ground system for each new satellite or constellation is not only costly, but it limits flexibility. The satellite-specific nature of existing ground systems makes it difficult to build third-party applications that can easily be installed across systems. Moreover, it limits the ability of operators to simultaneously connect to multiple constellations using the same ground system. However, industry has created a workaround. Satellites may not be physically inaccessible, but they frequently communicate with operators over radio frequency signals. If a given payload's functions are largely virtualized — meaning they are software-defined and not hardware-defined — then operators can alter a given satellite's capabilities and mission by simply installing new software. Hence, the growing interest in building software-defined payloads. In fact, the next GPS payload will feature an entirely digital payload. With OpenSpace, Kratos is applying the basic principles of software-defined payloads to satellite ground systems — the technology used to command and control the spacecraft once it's on orbit. The ground system is what operators use to cue, download data from, and monitor their satellites. According to Kratos, its OpenSpace platform is the first dynamic, software-defined ground system that will apply those lessons learned from the space layer to the ground layer. “What we did with OpenSpace is we actually started from scratch with an entirely new platform that is based on the fundamentals of network function virtualization (NFV) and software-defined networking (SDN),” said Greg Quiggle, vice president of product management at Kratos, comparing the platform to the architecture underlying new 5G networks. “We took that same basic premise and we applied it to the way a ground system should be built to interconnect software-defined satellites, multi-constellation networks and a terrestrial network.” A key feature that enables OpenSpace is the digitization of the radio frequency signal as close to the antenna as possible, transforming that flow of data into what is effectively a large ethernet network. “Once you've done that — you move from [radio frequency] to digital — you now can process those subchannels, that bandwidth, in software through something called virtualized network functions,” Quiggle explained. The platform takes typical purpose-built ground station hardware — splitters, channelizers, matrix switches, modulators, demodulators and much more — and recreates them in a virtual environment. Once the radio frequency data is digitized, it can be processed through all of these virtual tools. One consequence of that is the software can be run anywhere — it does not have to be located at the antenna. Operators can run this solution in the cloud or in a classified data center, said Quiggle. That also means any ground station using OpenSpace can be quickly adjusted for different uses. For instance, take an operator who needs to interact with satellites. By using an OpenSource-enabled ground station, that individual can load his or her own software-defined solution into the system, connect with the satellite, download any data and cue the spacecraft for its next tasks. Once that satellite passes out of view, a second operator can take over the ground station, load an entirely different software-defined solution and interact with the satellite as it passes over. In this scenario, both users were able to use a single ground station to communicate with their own unique satellites. In another example, the first user is ready to use one ground station to interact with a satellite as it passes overhead, but inclement weather disrupts the process. Instead of waiting for the satellite to pass overhead again, the user simply needs to find the next available ground station on the satellite's course, virtually load software and then access the satellite from there. Military applications OpenSpace is clearly set to have commercial implications. In fact, Microsoft announced Oct. 20 that it will use OpenSpace as part of its Azure Orbital ground-station-as-a-service. Azure Orbital is Microsoft's answer to Amazon Web Services' Ground Station model, which allows customers to access their satellites by renting time on Amazon's ground stations and the AWS platform. It's a business model that could be attractive to small companies looking to field small satellites without building massive, cost-prohibitive ground systems to support them. But a product like OpenSpace could make an even bigger splash in the military space community, especially when it comes to satellite communications. In a statement released earlier this year, the Space Force laid out its concept of “fighting SATCOM.” The service envisions enabling war fighters to roam among satellite communications providers to ensure forces remain connected even if one provider is jammed or unavailable. That level of fluidity requires some major changes to how the military has traditionally approached satellite communications. “One of the things that the government is looking for very specifically is the ability to create an open enterprise-wide architecture for their protected communications systems,” said Frank Backes, senior vice president for federal space-related business at Kratos. “And as they move forward with proliferated LEO [low-Earth orbit] and MEO [medium-Earth orbit] constellations to add communication options, resiliency and capability to their current geosynchronous space communications environment ... this ground architecture is very critical to the defense goals and what they're trying to achieve,” he added. Currently, the ability to roam between constellations to avoid jamming is hampered by stovepiped systems, which are designed to work with a single satellite or a set of satellites. Because OpenSpace can leverage any radio frequency antenna, digitizes that signal and process that data in software, the operator can use the same ground station for multiple constellations. Kratos certainly hopes that its system could be the ground solution for the “fight SATCOM” concept. “Today, the U.S. government on the defense side is very dependent on their own antennas and their own hardware that is deployed for their communications infrastructure and their satellite command-and-control environment. And one of the reasons for that is the hardware that is out in the field today is protected hardware: It may have specialized waveforms, it may have specialized components, it may even have specialized encryption infrastructure,” Backes said. “That limits the military to only using certain apertures for communications. As soon as you move to this dynamic environment — this OpenSpace environment that Kratos is talking about — now you have the ability to use any commercial or military antenna infrastructure for your system and dynamically configure that as needed. “Combined with the ability to move protected hardware out of the field and putting that into a controlled cloud environment, now all of a sudden I have the ability to create the resilient environment that the Department of Defense is looking for.” Kratos told C4ISRNET in a statement that the company “is providing satellite ground system engineering support on several DoD pLEO space segment teams.” In addition, the company noted it “will be bidding our OpenSpace and [Eterprise Ground Services] capabilities on pLEO systems as those opportunities mature.” “When you look at ... the new LEO and MEO constellations — just from a pure imaging/sensing perspective — we don't see how you make those happen without an element of a dynamic software-defined ground,” Carrai said. “The timing has to be second or milliseconds. That we think is going to be essential for us to really get what we're paying for and we need from a U.S. constellation perspective.” https://www.c4isrnet.com/battlefield-tech/space/2020/10/20/are-software-defined-ground-stations-the-next-big-leap-kratos-is-betting-on-it/

  • House panel advances $733B defense budget bill over GOP objections

    House panel advances $733B defense budget bill over GOP objections

    By: Leo Shane III and Joe Gould WASHINGTON ― House lawmakers advanced a $733 billion defense policy bill on Thursday after nearly 21 hours of sometimes heated debate on the size of the Pentagon budget, the size of the country's nuclear arsenal and a host of other military priorities for next year. The 33-24 final vote by the House Armed Services Committee on the draft of the defense authorization bill marked one of the most divided stances from the committee in years, as Republicans voiced concerns with Democrats' priorities in the measure. The legislation, which sets military spending policy for the upcoming fiscal year, has been adopted by Congress for 58 consecutive years, usually by sizable bipartisan margins. Committee officials insist that's because the needs of the military usually rise above the partisan politics of Capitol Hill. But this year, the narrow passage out of committee illustrated the stark divide in defense policy between the two parties, and hints at a lengthy battle to come as the measure moves across Capitol Hill to the Republican-controlled Senate in the coming weeks. Committee Chairman Adam Smith, D-Wash., in recent days said he is committed to finding a palatable bill for both Republicans and Democrats. But during the marathon debate he repeatedly defended his party's plans for $733 billion in defense spending for fiscal 2020 as a responsible and sufficient mark. “By a reasonably comfortable margin, this is the largest budget we will have ever passed in Congress (for defense) and it's a significant improvement on where we were before,” he said before the committee vote. Smith had already set aside some of his own priorities in a bid to win support from the panel's hawkish Republicans, who are likely to influence their caucus when it comes time to vote the bill out of the House. Without that support, Democrats may struggle to gather enough votes from progressives in their own caucus, who have questioned even the lower level of spending. But Senate Republicans have already set their authorization bill draft at $750 billion, a mark recommended by the White House and defended by HASC ranking member Mac Thornberry, R-Texas. He said that the figure is needed to keep pace with military modernization and readiness needs. Thornberry's amendment included a lengthy laundry list of weapons and platforms left out of the bill. “I worry that we talk about this like it's just numbers we're pulling out of the air,” he said. “These are real things. An aircraft carrier gets delayed a year if $733 billion is the way it comes out.” The bill includes a 3.1 percent pay raise for troops next January — a point of agreement on both sides that Smith repeatedly referenced — and provisions for increased protections for sexual assault victims, increased oversight of military housing problems and parameters for a new Space Corps within the Air Force. But fights over the effects of climate change on national security, limitations on the use of the Guantanamo Bay detention camp and a provision mandating gender integration in Marine Corps basic training further divided the committee. On a series of Republican amendments aimed at preserving funds for the nuclear arsenal — including one to protect deployment of low-yield nuclear weapons on submarines — Democrats repeatedly defeated Republican proposals. Similarly, the committee upheld several provisions designed to put a check on President Donald Trump's ability to shift resources from the Defense Department to the U.S. southern border with Mexico. Democrats have accused Trump of abusing his emergency powers to shift Department of Defense funds for the border and send thousands of troops there. In the committee debate, Republicans generally argued Trump is taking necessary and normal steps to secure the border given political resistance to addressing the issue. “I want everybody to understand we have been sending DoD assets to the border since the Alamo,” said Rep. Mike Rogers, who sponsored one of the amendments. “We have to do it in order to keep our border secure and deal with the humanitarian crisis.” The measure now shifts to the full House, where Smith and Democratic leadership will have to build a coalition of supporters to get the measure to negotiations with the Senate. That chamber will vote on its draft next week. Work on a compromise draft between the House and Senate is expected to last through most of the summer and fall. https://www.defensenews.com/congress/2019/06/13/house-panel-advances-733b-defense-budget-bill-over-gop-objections/
