DARPA: Expediting Software Certification for Military Systems, Platforms

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.

    A compromise is needed on trans-Atlantic defense cooperation

    By: Hans Binnendijk and Jim Townsend The incoming European Commission president, Ursula von der Leyen, will need to work with Washington to defuse a quietly simmering trans-Atlantic defense cooperation issue that, if left unsettled, could do more long-term damage to the NATO alliance than U.S. President Donald Trump's divisive tweets. The United States for years has sought to stimulate increased European defense spending while minimizing wasteful duplication caused by Europe's fragmented defense industry. Europe has finally begun to deliver: Defense spending is up significantly, and the European Union has created several programs to strengthen its defense industries. But in the process, the EU has created a trans-Atlantic problem. These advances in Europe could come at the expense of non-EU defense industries, especially in the U.S. The European Defence Fund, or EDF, established in 2017, is designed to support the cooperative research and development efforts of European defense industries, especially small and mid-sized firms. Three eligible companies from at least three EU countries need to apply in a coordinated fashion to receive project research and development funding, which can be up to a 100 percent grant for the research phase. Plans call for spending about $15 billion between 2021 and 2027 to strengthen Europe's defense R&D and stimulate innovation. Model projects include the Eurodrone and ground-based precision strike weapons. A second related EU program, Permanent Structured Cooperation, or PESCO, also inaugurated in 2017, focuses more on efforts to foster defense cooperation among subsets of European states. Initially envisioned in the 2009 Lisbon Treaty, PESCO is an effort to develop a more comprehensive European defense consistent with EU's common foreign and security policy needs. Thus far, 25 of 28 EU nations have signed up, with 34 modest cooperative projects agreed to by the European Council. The EU estimates that the inefficiency caused by the lack of adequate defense cooperation costs its members between $25 billion and $100 billion annually. These new EU programs, designed to pool and share scarce defense resources, are intended to help address that problem. But the exclusivity of these approaches favor the defense industries of EU members, and the hostile Trump administration rhetoric toward the EU is only supercharging this controversy. President Trump's negative attitude toward NATO and European leaders has undercut European confidence in American trans-Atlantic leadership and strengthened a call in some European capitals for European “strategic autonomy.” Part of this autonomy is developing a more capable and independent European military supported by a stronger European defense industry. A stronger European military capability is a goal shared on both sides of the Atlantic, but not at the expense of defense cooperation. While European leaders understand that they are probably decades away from real, strategic autonomy and military independence, they are shaping the EDF and PESCO approaches to protect European defense industry by being fairly exclusive of U.S. or other non-EU defense industries. This has U.S. defense officials worried. A May 2020 letter to the EU from two senior U.S. officials stated their “deep concern” about the programs' regulations. While current EDF and PESCO programs are small, U.S. officials are worried they will set precedents and will be a model for more ambitious European defense cooperation in the future. They fear not only that U.S. industry will be cut out, but that two separate defense industry tracks will be established that will undercut NATO interoperability and promote further duplication. Some U.S. officials have threatened U.S. retaliation unless changes are made. EU officials respond that these criticisms are excessive. They note that some American defense firms established in European countries will be eligible, that there is nothing comparable to the “Buy American Act” in Europe, that plenty of trans-Atlantic cooperative projects can take place outside of these two EU programs, that the PESCO projects will be guided by both EU and NATO requirements, and that over 80 percent of European international defense contracts go to U.S. firms anyway. They also note that a deterrent to U.S.-EU defense cooperation is that U.S. arms transfer control regulations create potential American restrictions on the sale to third countries of any U.S.-EU cooperative weapons systems that contain U.S. technology. NATO Secretary General Jens Stoltenberg, who seems caught in the middle, has supported both EDF and PESCO, so long as the results fill NATO capability gaps and do not lead to further duplication. Flexibility will be needed on both sides of the Atlantic to defuse this issue before it becomes too difficult to manage. Some opportunities for third-country participation will be needed. Possible approaches to level the playing field include focusing on modifying PESCO, which is still under development in the EU. One suggestion is to create a “white list” of NATO nations not in the EU (such as the U.S., Canada, Norway, post-Brexit United Kingdom and Turkey) that might be invited to participate in selected PESCO projects on a case-by-case basis. This would at least set a precedent that PESCO does not completely exclude third countries. And it would strengthen EU-NATO defense links. Additionally, formal procedures might be established for closer cooperation between the PESCO project selection process and NATO's defense planning process. This will help avoid duplication and identify at NATO those areas where NATO nations outside the EU could cooperate on PESCO projects, The U.S. might also consider amending its arms export control legislation to waive the third-country transfer review requirement for the export of U.S.-PESCO joint projects if the sale would be made to a country to which the U.S. would have made a similar sale. EU internal negotiations on EDF are finished, and changes will be hard to make. Plus, EDF provides R&D funding grants that use European financial resources. While some $118 million in U.S. Defense Advanced Research Projects Agency funds go to European firms, that is about 3 percent of DARPA's budget. So the U.S. might ask for some modest reciprocity from the EDF. But more constructively, DARPA and the EDF might co-fund R&D for joint U.S.-EU projects. The United States has much to gain from a strong European defense industry. Europe has much to gain from cooperation with the U.S. defense industry. All NATO allies need to stimulate defense innovation to compete effectively with Russia and China. Both sides of the Atlantic have much to lose if this issue further disrupts NATO's already shaky political equilibrium. Hopefully von der Leyen's experience as a former German defense minister will help her to understand the urgency and to find a solution to this problem.

    Lockheed Martin Delivers 134 F-35s in 2019, Exceeding Annual Commitment

    Fort Worth, Texas, December 30, 2019 /PRNewswire/ -- Lockheed Martin (NYSE: LMT) delivered the 134(th) F-35 aircraft for the year today, exceeding the joint government and industry 2019 delivery goal of 131 aircraft. One hundred and thirty-four deliveries represent a 47% increase from 2018 and nearly a 200 percent production increase from 2016. Next year, Lockheed Martin plans to deliver 141 F-35s and is prepared to increase production volume year-over-year to hit peak production in 2023. "This achievement is a testament to the readiness of the full F-35 enterprise to ramp to full-rate production and we continue to focus on improving on-time deliveries across the entire weapons system," said Greg Ulmer, Lockheed Martin vice president and general manager of the F-35 program. "We have met our annual delivery targets three years in a row and continue to increase production rates, improve efficiencies and reduce costs. The F-35 is the most capable fighter jet in the world, and we're now delivering the 5(th) Generation weapon system at a cost equal to or lower than a less capable 4th Generation legacy aircraft." The 134(th) aircraft is a Short Takeoff and Vertical Landing (STOVL) model for the United States Marine Corps. In 2019, deliveries included 81 F-35s for the United States, 30 for international partner nations and 23 for Foreign Military Sales customers. Unit and Sustainment Costs Decrease, Readiness Improving Using lessons learned, process efficiencies, production automation, facility and tooling upgrades, supply chain initiatives and more - the F-35 enterprise continues to significantly improve efficiency and reduce costs. The price of an F-35A is now $77.9 million, meeting the $80 million goal a year earlier than planned. The F-35's mission readiness and sustainment costs continue to improve with the global fleet averaging greater than 65% mission capable rates, and operational squadrons consistently performing near 75%. Lockheed Martin's sustainment cost per aircraft per year has also decreased four consecutive years, and more than 35% since 2015. Program Maturity and Economic Impact With more than 490 aircraft operating from 21 bases around the globe, the F-35 plays a critical role in today's global security environment. Today, 975 pilots and 8,585 maintainers are trained, and the F-35 fleet has surpassed more than 240,000 cumulative flight hours. Eight nations have F-35s operating from a base on their home soil, eight services have declared Initial Operating Capability and four services have employed F-35s in combat operations. In addition to strengthening global security and partnerships, the F-35 provides economic stability to the U.S. and international partners by creating jobs, commerce and security, and contributing to the global trade balance. Thousands of men and women in the U.S. and around the world build the F-35. With more than 1,400 suppliers in 47 states and Puerto Rico, the F-35 Program supports more than 220,000 jobs.
