WASHINGTON — Despite impacts from the coronavirus pandemic, the U.S. Air Force's B-21 Raider program remains on track as Northrop Grumman continues production of the first B-21 bomber, the head of the service's Rapid Capabilities Office said Thursday.
Speaking at a Mitchell Institute for Aerospace Studies event, RCO Director Randall Walden acknowledged that some B-21 suppliers had been adversely affected by the ongoing coronavirus pandemic. For instance, Spirit AeroSystems — which builds large composite aerostructures for the bomber — has run into challenges not only on its defense side, but also for its commercial division due to the halt in Boeing 737 Max production, Walden said.
Spirit received $80 million in Defense Production Act funds meant to help stimulate struggling businesses, and Walden noted that the company also funneled employees who normally work on the 737 Max line into augmenting B-21 production efforts.
“The folks that are not manufacturing 737s and those components came over to our production line and really kind of beefed up — where people had some COVID issues — they beefed up that portion of our production,” he said. “Right now, the components that we're building are really for the test fleet, but the good news: All of what we're doing today is really insightful for what we're doing for production in the future.”
After completing a critical design review in 2018, B-21 prime contractor Northrop Grumman is currently building the first B-21 test aircraft in Palmdale, California. The Air Force plans to buy at least 100 Raiders.
On Aug. 3, Walden traveled with Defense Secretary Mark Esper to Northrop's B-21 design and development office in Melbourne, Florida, to receive a program update.
“I think overall his takeaway was he's happy with the progress we're making,” Walden said. “The good news is all of the tough critical designs, all of the hard engineering is kind of behind us, and now it's a matter of actually producing the airplane and actually rolling it out and getting on with the developmental flight test activities.”
Walden said his office has flight tested some B-21 mission systems and avionics on a surrogate aircraft to work though software bugs and design problems before installation on the actual B-21 test aircraft.
“I know we're not going to be immune from design flaws. We're going to have to work through those, and we're doing some of that today. From my perspective, I want to find out what those design deficiencies were as fast as I can, get on with a solution, get that into the program in the development phase, and get on with production.”
In July 2019, Air Force Vice Chief of Staff Gen. Stephen Wilson said the Raider could take to the skies in about “863 days,” which would pinpoint an inaugural flight in December 2021. Walden has since said that would be the earliest possible date for first flight.

The first version of the new cybersecurity requirements the Pentagon wants military contractors to follow could be finalized as soon as Jan. 31. Katie Arrington, chief information security officer for the Office of the Under Secretary of Defense for Acquisition and the point person for the Cybersecurity Maturity Model Certification (CMMC), told an audience Jan. 28 that she will have the requirements by the end of the month. The CMMC is a tiered cybersecurity framework that grades companies on a scale of one to five. A score of one designates basic hygiene and a five represents advanced hygiene. Arrington said Jan. 28 that the lowest level will become the default for Department of Defense contracts and will include basic tasks such as changing passwords. Speaking at an event hosted by the law firm Holland and Knight, Arrington said the new standards won't be in effect overnight. The auditors and assessors who will grade companies need training and new contracts will be slowly phased in. “The likelihood that any awards will be made until 2021 [of the certification] is, I would say, highly unlikely,” she said. She noted that companies are not required to have CMMC certification until the time of award. “You have a full year to get yourselves set, to get yourself in position.” According to one slide in her presentation, all new contracts will have the requirements in fiscal year 2026. Arrington expects 1,500 companies to be certified by the end of 2021. The requirements are expected to be free of jargon and overly technical language that can often make military documents befuddling. “I asked if it could be created on an eighth grade reading level. Why? Because I'm not smart and I owned a small business and I fell prey to this,” she said. “I needed it to be in something that anybody could adapt to. We hear companies all the time say my nephew is doing my cybersecurity. I need your nephew to read what I need him to do.” Arrington promised that the requirement would not become a simple checklist, because if it does “I've failed. We failed.” Moreover, she suggested the framework be reevaluated at least once each year because cyber threats will continue to evolve. https://www.fifthdomain.com/dod/2020/01/28/new-cybersecurity-standards-for-contractors-could-be-finalized-this-week/

Military systems are increasingly using software to support functionality, new capabilities, and beyond. Before a new piece of software can be deployed within a system however, its functional safety and compliance with certain standards must be verified and ultimately receive certification. As the rapid rate of software usage continues to grow, it is becoming exceedingly difficult to assure that all software considered for military use is coded correctly and then tested, verified, and documented appropriately. “Software requires a certain level of certification – or approval that it will work as intended with minimal risks – before receiving approval for use within military systems and platforms,” said Dr. Ray Richards, a program manager in DARPA's Information Innovation Office (I2O). “However, the effort required to certify software is an impediment to expeditiously developing and fielding new capabilities within the defense community.” Today, the software certification process is largely manual and relies on human evaluators combing through piles of documentation, or assurance evidence, to determine whether the software meets certain certification criteria. The process is time consuming, costly, and can result in superficial or incomplete evaluations as reviewers bring their own sets of expertise, experiences, and biases to the process. A lack of a principled means of decomposing evaluations makes it difficult to create a balanced and trustworthy process that applies equally to all software. Further, each subsystem and component must be evaluated independently and re-evaluated before it can be used in a new system. “Just because a subsystem is certified for one system or platform does not mean it is unilaterally certified for all,” noted Richards. This creates additional time delays and review cycles. To help accelerate and scale the software certification process, DARPA developed the Automated Rapid Certification Of Software (ARCOS) program. The goal of ARCOS is to create tools and a process that would allow for the automated assessment of software evidence and provide justification for a software's level of assurance that is understandable. Taking advantage of recent advances in model-based design technology, “Big Code” analytics, mathematically rigorous analysis and verification, as well as assurance case languages, ARCOS seeks to develop a capability to automatically evaluate software assurance evidence to enable certifiers to rapidly determine that system risk is acceptable. “This approach to reengineering the software certification process is well timed as it aligns with the DoD Digital Engineering Strategy, which details how the department is looking to move away from document-based engineering processes and towards design models that are to be the authoritative source of truth for systems,” said Richards. To create this automated capability, ARCOS will explore techniques for automating the evidence generation process for new and legacy software; create a means of curating evidence while maintaining its provenance; and develop technologies for the automated construction of assurance cases, as well as technologies that can validate and assess the confidence of an assurance case argument. The evidence generation, curation, and assessment technologies will form the ARCOS tools and processes, working collectively to provide a scalable means of accelerating the pathway to certification. Throughout the program's expected three phases, evaluations and assessments will occur to gauge how the research is progressing. ARCOS researchers will tackle progressively more challenging sets of software systems and associated artifacts. The envisioned evaluation progression will move from a single software module to a set of interacting modules and finally to a realistic military software system. Interested proposers will have an opportunity to learn more during a Proposers Day on May 14, 2019, from 8:30AM to 3:30PM (EST) at the DARPA Conference Center, located at 675 N. Randolph Street, Arlington, Virginia, 22203. The purpose of the Proposers Day is to outline the ARCOS technical goals and challenges, and to promote an understanding of the BAA proposal requirements.
